China has become an important global sourcing base for eco laundry sheets, supported by mature daily-chemical supply chains, flexible private-label manufacturing, competitive packaging resources, and growing expertise in concentrated, water-soluble cleaning formats. For procurement managers, however, choosing a supplier should not be reduced to comparing a unit price or a generic "biodegradable" claim.
This guide evaluates ten China-based manufacturers and supplier candidates from the perspective of an international buyer seeking a long-term OEM/ODM partner. It focuses on factory credentials, formulation and R&D capability, scalable capacity, quality-control systems, export readiness, documentation transparency, and customization depth—not marketing language alone.
China's broader exports of HS Chapter 34 products—covering soap, organic surface-active agents and washing preparations—reached approximately US$9.12 billion in 2025, up 14.4% year on year, illustrating the scale of the country's detergent and cleaning-product manufacturing ecosystem. The laundry-sheet category is also gaining momentum as retailers and DTC brands look for lower-weight formats, reduced liquid shipping, plastic-reduction initiatives, and easy-dose household-cleaning products.
Eco laundry sheets are thin, pre-dosed detergent sheets designed to dissolve in water and release concentrated cleaning ingredients. They are commonly positioned around convenience, lightweight shipping, low-mess handling, compact storage, and potential packaging reduction compared with conventional bulky liquid-detergent formats.
China is attractive for this category because it combines several manufacturing advantages:
- Daily-chemical supply chain depth: Surfactants, enzymes, fragrance compounds, chelating agents, polymers, colorants, packaging films, paper cartons, and flexible packaging can often be sourced within established regional industrial networks.
- OEM/ODM flexibility: Many Chinese manufacturers can support formula adjustment, fragrance selection, sheet size, color, perforation format, pack count, retail packaging, multilingual artwork, and private-label programs.
- Cost structure and scaling: China remains competitive for both trial orders and retail-scale production, especially where the buyer needs multiple SKUs or a coordinated household-cleaning range.
- Export infrastructure: Guangdong, Zhejiang, Shanghai, Jiangsu, Shandong, and other coastal regions have mature logistics connections for sea freight, air freight, e-commerce fulfillment, and consolidated shipments.
- Format innovation: Beyond laundry detergent sheets, established suppliers may also develop dishwashing sheets, floor-cleaning sheets, color-catcher sheets, dryer sheets, fragrance boosters, pet-cleaning products, and personal-care formats.
Industry estimates vary significantly because detergent sheets are often grouped with broader laundry-detergent or household-cleaning categories. One market report estimated China's laundry detergent sheet market at US$150.58 million in 2024 and projected it could reach US$491.37 million by 2033, with a projected 14.16% CAGR from 2025 to 2033. This should be treated as third-party market research rather than an official government statistic.
A professional buyer should not select an eco laundry sheet factory based only on Alibaba listings, social-media videos, or a low quotation. For this guide, the following criteria were prioritized.
| Evaluation Area | What Buyers Should Check | Why It Matters |
|---|---|---|
| Manufacturing identity | Business license, factory address, production license, audit records | Helps distinguish a true manufacturer from a trader or virtual brand |
| Quality systems | ISO 9001 scope, in-process QC, batch records, traceability, retained samples | Reduces consistency risk between approved samples and mass production |
| Environmental controls | ISO 14001, packaging plans, wastewater controls, substantiated environmental claims | Relevant when the buyer markets products as eco-conscious |
| Formula capability | Surfactant system, enzyme compatibility, fragrance stability, cold-water dissolution | Determines cleaning performance and customer satisfaction |
| OEM/ODM depth | Formula development, artwork, pack size, fragrance, claims support, packaging | Important for private-label differentiation |
| Compliance readiness | SDS, ingredient disclosure, safety reports, REACH/RoHS where relevant, destination-market documentation | Helps buyers prepare for retailer, customs, and regulatory review |
| Production resilience | Capacity, production lines, raw-material alternatives, lead-time control | Helps prevent stockouts during promotions or seasonal demand |
| Communication quality | Response speed, specification accuracy, sample feedback handling, change-control discipline | Often predicts project execution quality |
| Export experience | Destination markets, shipping terms, labeling support, carton optimization | Reduces avoidable documentation and logistics errors |
| Commercial transparency | MOQ, tooling fees, payment terms, sample cost, claim limitations | Prevents pricing surprises after product development begins |
Shortlist three to five suppliers, request comparable technical documentation, test physical samples, conduct a pilot order, and then scale. A low initial quote can become expensive if the supplier cannot maintain sheet weight, dissolution behavior, fragrance consistency, carton strength, or shipment timing.

- The company reports more than three self-owned factories and annual capacity of approximately 30,000–40,000 metric tons across its product portfolio. Buyers should clarify what proportion of that figure applies specifically to laundry sheets, because total group capacity and product-line capacity are not interchangeable.
Which facility and production line will manufacture the requested eco laundry sheets?
- Is the proposed formula sulfate-free, phosphate-free, enzyme-containing, plant-derived, or fragrance-free—and what evidence supports each claim?
- What is the minimum order quantity for stock formulas versus fully customized formulas?
- Can the supplier provide stability, dissolution, microbial, safety, and wash-performance test data?
- Can the supplier support U.S., EU, UK, Middle East, Southeast Asia, or Australian labeling requirements for the proposed product?
For international buyers that value responsive communication, iterative sample development, and brand-specific OEM customization, Foshan Magic Crystal is a strong first supplier to include in a qualified shortlist.
Location: Yiwu, Zhejiang, China
Core focus: Solid-form household-cleaning products and detergent sheets
OEM/ODM suitability: Strong for brands prioritizing intelligent manufacturing, solid cleaning formats, and formal quality-management systems
Best suited for: Retailers, importers, and household-cleaning brands seeking a more structured detergent-sheet production environment
Zhejiang Kelee Technology is a specialized manufacturer associated with solid-form cleaning products, including detergent sheets. Publicly available company information describes a 100,000-class dust-free workshop, IoT-enabled production lines, and management-system certifications including ISO 9001, ISO 14001, and ISO 45001. It also indicates that key products have undergone SGS third-party safety and performance testing.
For buyers, this profile may be relevant where production hygiene, documentation, automation, and operational consistency are high priorities. Yiwu also offers advantages for buyers combining product sourcing with accessories, retail packaging, promotional items, and cross-border e-commerce support.
- Confirm whether its cited testing applies to the exact product formula and packaging you intend to purchase.
- Ask for the current cleanroom classification documentation and how it applies to detergent-sheet production.
- Request batch-specific QC parameters, such as sheet weight tolerance, moisture content, dissolution time, pH, active content, and packaging-seal integrity.
- Verify minimum order quantities separately for standard formulations, custom fragrance, custom color, carton printing, and outer-case configurations.
Location: Qingdao, Shandong, China
Core focus: Liquid-less and plastic-reduction household-cleaning products
OEM/ODM suitability: Suitable for buyers focused on laundry sheets and adjacent sheet-format home-care products
Best suited for: Eco-oriented brands, Amazon sellers, specialty retailers, and buyers that want a sheet-format product portfolio
Yuemian positions itself around liquid-less, plastic-free, biodegradable, and eco-friendly household-washing products. Its public materials list laundry detergent sheets, scent booster beads, dishwasher sheets, color-catcher sheets, and softener dryer sheets among its key categories. The company also states that it has 15 years of production experience, nine years of export experience, OEM/ODM capability, ISO 9001 compliance, and a Raschel production line capable of producing more than 10,000 square meters per day.
This may make Yuemian relevant for buyers that want a supplier with a visible focus on sheet-based laundry and home-care formats rather than a broad conventional-detergent catalog.
- Whether the stated daily square-meter capacity translates into your requested sheet dimensions, gram weight, pack count, and monthly finished-pack output.
- Whether biodegradability claims are supported by a recognized test method rather than broad marketing language.
- Whether the "plastic-free" claim applies to the product, the primary package, the shipping carton, or the full packaging system.
- Whether the factory can produce premium formats such as fragrance-free, sensitive-skin, color-safe, enzyme-enhanced, baby-laundry, or cold-water-dissolving sheets.
Core focus: Laundry pods, laundry sheets, dishwasher tablets, and eco-household/personal-care products
OEM/ODM suitability: Strong for buyers that need coordinated capsule, tablet, and sheet-format product development
Best suited for: Brands planning a multi-format laundry or household-cleaning range
Foshan Jingliang Daily Chemicals offers products across laundry pods, laundry sheets, dishwasher tablets, fruit-and-vegetable cleaning tablets, and related household-care categories. Its public materials describe customization covering appearance, fragrance, formula, packaging, PVA-film adaptation, and finished-product manufacturing. The company also lists ISO 9001, ISO 45001, patents, and other product or quality qualifications.
The supplier may be particularly suitable for a buyer wanting to source several formats from one regional partner—for example, eco laundry sheets plus dishwasher tablets and laundry pods.
- Broader format capability beyond detergent sheets.
- Potentially suitable for cross-selling household-cleaning ranges under one brand.
- Guangdong location can support consolidated export logistics.
- Product-development capability may be useful when a brand wants different price tiers or fragrance variants.
PVA film, water-soluble polymers, and tablet/pod production introduce different technical and compliance considerations from laundry sheets. If a supplier proposes a multi-product program, buyers should evaluate each category separately rather than assuming that strong pod capability automatically proves strong sheet performance.
Location: Dongguan, Guangdong, China
Core focus: Laundry detergent sheets, dishwashing sheets, fragrance boosters, and cleaning-sheet products
OEM/ODM suitability: Suitable for buyers seeking Guangdong-based household-cleaning sheet production
Best suited for: Private-label importers, e-commerce sellers, and distributors requiring product-range flexibility
Dongguan UFine Daily Chemical is commonly listed in Chinese detergent-sheet supplier overviews as a producer associated with laundry detergent sheets, dishwashing sheets, fragrance boosters, and related cleaning-sheet formats. Its Guangdong location can be useful for buyers who prioritize access to Pearl River Delta export logistics and packaging resources.
Because public information may not provide a complete view of current production capacity or certification scope, procurement teams should treat this supplier as a candidate for direct qualification rather than relying on directory summaries.
- Request business-registration details and the exact factory address.
- Confirm whether manufacturing is conducted in-house or by subcontractors.
- Ask for a product technical data sheet and a complete SDS for every shortlisted formula.
- Request production-line photos or a live video factory audit focused specifically on mixing, casting/coating, drying, cutting, packaging, and final inspection.
- Compare a physical sample against the approved mass-production specification.
Location: Shanghai, China
Core focus: Household-cleaning and laundry-care products
OEM/ODM suitability: Potentially relevant for buyers looking for an established household-cleaning company with broader category experience
Best suited for: Larger buyers that value established domestic-brand heritage and a broad cleaning-products portfolio
Shanghai Hutchison WhiteCat is associated with China's established household-cleaning sector and is often included in supplier or manufacturer lists covering dishwashing and laundry-related products. For buyers, a large, diversified household-care manufacturer may offer strengths in category knowledge, formulation resources, quality systems, and scale.
However, a buyer should not assume that a major conventional-detergent producer automatically offers the same flexibility as a specialist eco laundry sheet factory. Some large companies may prefer high-volume programs, have more formal development timelines, or maintain less flexibility for small custom projects.
- Better suited to established distributors, supermarket programs, or higher-volume private-label opportunities.
- May be less suitable for early-stage brands needing very low MOQs, frequent artwork changes, or multiple small pilot iterations.
- Buyers should clarify whether eco laundry sheets are made internally, through a dedicated factory, or through an approved partner facility.
Location: Hangzhou, Zhejiang, China
Core focus: Daily-chemical and household-cleaning products
OEM/ODM suitability: Potentially suitable for buyers seeking a Zhejiang-based supplier for private-label daily-care products
Best suited for: Brands seeking product-development support and access to Zhejiang's broader consumer-goods supply chain
Hangzhou Miuge Chemical Commodities Science & Technology is often referenced in manufacturer lists related to detergent-sheet or daily-chemical sourcing. Zhejiang's industrial environment can be attractive for export-focused brands because it combines access to ports, e-commerce ecosystems, packaging suppliers, and varied consumer-goods manufacturing resources.
Before selection, buyers should confirm whether the company's eco laundry sheets are internally manufactured, what production technology is used, and whether the product has already been exported to the buyer's destination market.
- Does the company formulate and manufacture detergent sheets at its own registered factory?
- What is the standard formula's active ingredient range and total sheet weight?
- Which countries have received the same or similar product?
- Can it supply current quality-system certificates and third-party testing for the exact formulation?
- What claim substantiation is available for "eco," "biodegradable," "plant-based," "plastic-free," or "non-toxic"?
Location: Shanghai, China
Core focus: Laundry sheets, floor-cleaning sheets, dishwashing products, fragrance boosters, color-grabber sheets, and dryer sheets
OEM/ODM suitability: Suitable for buyers that want a broad sheet-format household-care collection
Best suited for: Retailers and brand owners building coordinated laundry and home-cleaning product lines
Shanghai Finice Commodity is referenced in public supplier lists as being involved in laundry detergent sheets, fabric-care products, color-grabber sheets, floor-cleaning sheets, dryer sheets, fragrance boosters, and dishwashing-related products. Its broad catalog may appeal to buyers planning a comprehensive sheet-format cleaning collection rather than a single laundry SKU.
A category-expansion strategy can offer commercial benefits: it enables common visual branding, consolidated shipments, and cross-selling. Yet it also creates a qualification challenge—each product needs its own safety, performance, claims, and packaging review.
Evaluate the supplier's laundry sheets independently from its other categories. Request separate technical specifications, product tests, SDS documents, and commercial terms for every SKU rather than accepting a generic corporate certificate package.
Location: Jiangsu, China
Core focus: Smart-care and household-care product categories
OEM/ODM suitability: Potential candidate for buyers seeking Jiangsu-based product-development and manufacturing options
Best suited for: Buyers who want to diversify their supplier base beyond Guangdong and Zhejiang
Jiangsu Janix Smart Care is listed in industry-focused supplier overviews as a candidate in the detergent-sheet and smart-care product space. Jiangsu can be strategically useful for sourcing because it has strong industrial infrastructure, proximity to Shanghai-area logistics networks, and access to advanced manufacturing and chemical-supply ecosystems.
For procurement managers, geographic diversification can be valuable. Relying on only one region or one supplier leaves brands vulnerable to local disruptions, port congestion, raw-material shortages, or seasonal production constraints.
- Confirm whether the company owns its production assets or coordinates external manufacturing.
- Verify its active capacity for laundry sheets, not merely its total company capacity.
- Ask whether it can provide customer-approved samples within a documented development timeline.
- Request its policy for formula changes, raw-material substitutions, and customer approval before process changes.
Location: Guangdong / Zhejiang, China
Core focus: Daily chemicals and household-cleaning products
OEM/ODM suitability: Candidate options for buyers building a broader supplier comparison set
Best suited for: Procurement teams that need multiple quotations, regional alternatives, and contingency sourcing options
Guangdong Jieyi Group and Zhejiang Jifu Daily Chemical appear in supplier overviews related to detergent-sheet and daily-chemical manufacturing. Their inclusion in a sourcing shortlist can be useful for buyers seeking price comparisons, regional manufacturing alternatives, or suppliers capable of supporting broader household-care programs.
However, where public disclosures are limited, buyers should avoid treating online listings as proof of manufacturing capability. The appropriate next step is a structured supplier qualification process.
- Business license and manufacturer legal name.
- Factory address, not only a sales-office address.
- Current ISO certificate copies and certification scope.
- Product specification sheet for the proposed laundry sheet.
- Full SDS and ingredient disclosure suitable for the destination market.
- Quality-control plan and product inspection standards.
- Shelf-life and storage requirements.
- Test reports supporting performance and environmental claims.
- Export references or destination-market experience, where available.
- Written confirmation of whether subcontracting will be used.
The following table is a procurement-oriented comparison, not a substitute for supplier audits. "To verify" means that buyers should obtain current written confirmation directly from the manufacturer.
| Manufacturer | Region | Primary Strength | Publicly Indicated Capacity or Scale | MOQ | Certifications / Compliance Indicators | Ideal Buyer Profile |

Important: Certifications do not automatically confirm that a product is environmentally preferable, legally compliant in every market, or made at the factory you are visiting. They must be checked for validity, scope, issuing body, facility address, and product relevance.
"Eco laundry sheet" is not a technical standard by itself. It is a commercial description that may refer to packaging reduction, concentrated format, phosphate-free formulation, biodegradability, lower transport weight, plant-derived ingredients, or plastic-free positioning. Buyers should convert the marketing claim into measurable specifications.
A laundry sheet should dissolve adequately under the buyer's expected wash conditions. Ask suppliers to test:
- Cold-water dissolution.
- Short-cycle machine washing.
- Front-load and top-load machine compatibility.
- Hand-washing performance.
- High-water-hardness conditions.
- Low-water-volume cycles.
- Residue on dark fabrics.
- Residue inside detergent drawers or machine seals.
A sheet that works in a laboratory beaker may still leave fragments in a cold, short European wash cycle. This is why a buyer should test the actual product in representative consumer-use conditions.
A typical detergent-sheet formula may involve surfactants, water-soluble film-forming or sheet-forming components, chelating agents, enzymes, fragrances, preservatives where necessary, colorants, and performance additives.
Buyers should ask about:
- Total active content.
- Anionic, nonionic, amphoteric, or blended surfactant systems.
- Enzyme type and stability.
- Phosphate-free status.
- Optical brighteners and whether they are present.
- Fragrance allergen disclosure.
- Preservatives and restricted substances.
- pH after dissolution.
- Compatibility with delicate fabrics, wool, silk, baby clothing, and athleticwear.
- Antibacterial, deodorizing, stain-removal, or color-protection claim evidence.
A common issue in detergent-sheet sourcing is underweight production. A supplier may submit a heavy, well-performing sample, then reduce sheet weight during mass production to protect margin.
Your purchase specification should define:
- Sheet dimensions.
- Nominal grams per sheet.
- Allowable weight tolerance.
- Number of sheets per pack.
- Active ingredient tolerance.
- Perforation quality.
- Moisture-content range.
- Dissolution-time target.
- Packaging-seal standard.
- Retained-sample requirement.
Laundry sheets are sensitive to humidity. If the package barrier is weak, the sheets may absorb moisture, curl, stick together, lose fragrance, or partially dissolve before consumer use.
Ask suppliers to confirm:
- Primary-pouch material structure.
- Water-vapor transmission rate, where available.
- Seal-strength standard.
- Desiccant use, if applicable.
- Carton compression resistance.
- Storage conditions.
- Shelf-life under hot and humid transit conditions.
- Whether the packing has been tested in high-temperature and high-humidity environments.
One of the most expensive failures in laundry-sheet sourcing is not visible during initial sampling. A supplier may provide a high-quality prototype using better surfactants, higher active content, more fragrance, lower moisture, or a higher sheet weight. Once the buyer approves the sample, the mass-production batch may be produced using a lower-cost formula or a thinner sheet.
This problem is difficult to identify from packaging alone. A product can look almost identical while delivering weaker cleaning, slower dissolution, more residue, or lower fragrance retention.
1. Create a signed Golden Sample record for the approved version.
2. Record exact sheet dimensions, average sheet weight, active-content target, fragrance code, color, and pack count.
3. Require a pre-production sample from the actual bulk raw materials.
4. Approve a production batch only after checking an independently selected sample.
5. Include a no-substitution clause in the purchase order.
6. Retain sealed reference samples from every production batch.
7. Conduct pre-shipment inspection using random sampling from finished cartons—not samples provided by the factory in advance.
8. Ask a third-party inspection company to verify actual sheet weight, pack count, carton markings, moisture exposure, and packaging seals.
The internal rule many experienced buyers follow is simple: never approve a laundry sheet only by visual appearance or fragrance. The technical specification and batch consistency matter more.
A useful request for quotation should define more than "eco laundry sheets."
Include:
- Target country or countries.
- Intended retail channel: supermarket, Amazon, DTC, hotel, travel, wholesale, or subscription.
- Sheet size and target grams per sheet.
- Number of sheets per package.
- Fragrance-free, scented, hypoallergenic, enzyme-based, color-safe, or baby-safe requirements.
- Desired packaging format.
- Sustainability claims you intend to make.
- Required certificates and documentation.
- Target order quantity and annual forecast.
- Desired Incoterm: EXW, FOB, CIF, DDP, or another agreed term.
- Target launch date.
Do not rely only on certificates sent as PDF files. Verify:
- The legal company name on the certificate.
- The registered address and actual production address.
- The scope of certification.
- The certificate issue date and expiry date.
- The issuing certification body.
- Whether the product is produced at the audited site.
- Whether the supplier is acting as a manufacturer, trader, or brand owner.
For example, an ISO 9001 certificate whose scope says "trading of household products" does not prove that the company manufactures detergent sheets.
A reliable sampling sequence is:
1. Initial stock-formula sample.
2. Formula-adjustment sample.
3. Packaging mock-up and artwork proof.
4. Pilot production sample.
5. Pre-production approval sample.
6. Finished-goods pre-shipment inspection sample.
Avoid jumping directly from one small sample packet to a large commercial order.
During an on-site or virtual audit, ask to see:
- Raw-material receiving and lot control.
- Weighing and mixing records.
- Coating, casting, drying, cutting, and perforation processes.
- In-process weight checks.
- Metal detection or foreign-object controls where applicable.
- Primary-pouch sealing.
- Carton-packing checks.
- Finished-product warehouse humidity and temperature control.
- Retained-sample storage.
- Complaint handling and corrective-action records.
Laundry sheets are lightweight, but they are not automatically low-risk to ship.
Important shipping precautions include:
- Use moisture-resistant primary packaging.
- Avoid prolonged exposure to high humidity before container loading.
- Confirm carton strength for palletized or floor-loaded containers.
- Consider desiccants or container liners for humid shipping routes.
- Ensure outer cartons display proper lot, production date, shelf-life, and storage information.
- Confirm whether product labels satisfy destination-market language and hazard-disclosure rules.
- Use cargo insurance for first commercial orders.
China offers a strong sourcing environment for eco laundry sheets, but the most suitable manufacturer depends on the buyer's product strategy. A high-volume retailer may prioritize automation, audit systems, and reliable monthly capacity. A growing private-label brand may place more value on flexible MOQ, rapid communication, fragrance and packaging development, and the ability to expand into dishwashing, fabric-care, personal-care, or pet-cleaning categories.
For buyers seeking a China-based partner with a flexible OEM/ODM approach, R&D focus, multi-category care-product capability, and support for growing brands, Foshan Magic Crystal Technology Development Co., Ltd. is a supplier worth including in the first round of qualification. Its published certification history and product-development positioning provide a starting point, but—as with every supplier—commercial buyers should validate current documents, exact production capability, and product-specific compliance before final selection.
The strongest sourcing process is not "find the lowest price." It is: define your product specification, qualify several factories, validate documentation, test samples in real wash conditions, inspect pilot production, and scale only after batch consistency is proven.
Request the full certificate, not a cropped image. Check the legal company name, factory address, certificate number, issue date, expiry date, certification body, and certification scope. Then contact the certification body or use its official certificate-search platform when available. Most importantly, confirm that the scope covers manufacturing—not only trading, sales, or distribution.
Not necessarily. CE and RoHS are frequently misunderstood in consumer-product sourcing. Their relevance depends on the product type, destination market, and applicable regulations. For laundry detergent sheets, buyers should focus on chemical safety documentation, SDS, ingredient disclosure, product labeling, claim substantiation, destination-market rules, and retailer requirements. Do not use CE or RoHS as a substitute for a proper detergent-compliance review.
MOQ varies according to whether you use a stock formula and stock packaging, customize fragrance, change sheet weight, develop a new formula, require printed pouches, or need retail cartons. A supplier may accept a lower MOQ for a standard formulation but require substantially more volume for custom molds, printed materials, fragrance development, or fully customized packaging. Always request a written MOQ breakdown by component.
Ask what exactly is biodegradable: the surfactants, the sheet substrate, the full formula, or the packaging. Request the relevant test method, testing laboratory, test conditions, and product version tested. A claim based only on a raw-material supplier statement may not apply to the finished product. Your legal and marketing teams should review all environmental claims before using them on packaging or advertisements.
At a minimum, consider product safety testing, SDS review, ingredient review, dissolution testing, wash-performance testing, sheet-weight verification, moisture and packaging-seal tests, microbiological testing where relevant, stability testing, and claim-specific tests. Depending on the market and claims, you may also need fragrance allergen review, restricted-substance testing, biodegradability support, and retailer-mandated social-compliance or factory-audit reports.
