If you source molded fiber tableware for the US or EU market, PFAS has moved from a niche compliance topic to a hard procurement requirement. This guide explains exactly how to verify a PFAS-free claim on sugarcane tableware: what each certification proves, which laboratory tests to demand, how to check official registries, and what to ask suppliers before you commit to volume orders.

The short version
A compostability certificate is not proof of PFAS-free production. Verify with three layers: (1) certification as entry ticket, (2) accredited lab test reports with batch linkage, (3) registry checks plus production-process audit questions. In 2026, US state laws, the FDA phase-out and the EU PPWR all raise the cost of getting this wrong.

Why PFAS compliance is now the first question buyers ask

Three regulatory forces converged to make PFAS the first question on every foodservice RFQ.

The United States: state bans plus an FDA phase-out

In February 2024, the FDA announced that the remaining authorized uses of PFAS as grease-proofing agents in food contact packaging would be phased out of the US market. Under that announcement, sales of PFAS-containing food contact substances ended as manufacturers completed their phase-outs through 2025 — meaning the US market no longer has FDA-authorized PFAS grease-proofing for food packaging.

On top of that, a growing list of states restricts PFAS in food packaging directly:

Maine’s LD 1433 banned intentionally added PFAS in food packaging from January 1, 2022. California’s AB 1200, effective January 1, 2023, prohibits plant-based food packaging containing intentionally added PFAS and established a practical screening rule: products with 100 ppm or more total fluorine are presumed to contain intentionally added PFAS. Minnesota’s HF 2500 extended a similar ban from January 1, 2024, and states including New York, Vermont, Connecticut, Washington and Colorado have passed their own restrictions.

The commercial consequence is simple: a distributor selling into multiple states must be able to demonstrate, on paper, that the packaging it imports does not contain intentionally added PFAS. A single lab report can serve all of these buyers, but only if it is current, complete and linked to the actual product family.

The European Union: PPWR plus a universal PFAS restriction

In the EU, two parallel tracks matter for tableware importers.

First, the Packaging and Packaging Waste Regulation (PPWR), which entered into force in early 2025, introduces restrictions on PFAS in food contact packaging with compliance dates beginning in August 2026. Importers placing food contact packaging on the EU market therefore need documentation that demonstrates compliance ahead of the deadline — not after.

Second, the universal PFAS restriction proposal under the EU’s REACH regulation, submitted by Denmark, Germany, the Netherlands, Norway and Sweden in January 2023, is the broadest chemical restriction ever proposed in the EU. It targets the whole PFAS class and would eventually cover food packaging among many other applications. ECHA’s scientific committees have been evaluating it, and the timeline points to a decision in the 2026-2027 window. Several EU member states did not wait: Denmark banned PFAS in food packaging from July 1, 2020, and the Netherlands followed with its own restriction effective July 1, 2022.

What this means for buyers
Buyers who can show PFAS test documentation today have a head start: they can serve California, Maine, Minnesota and other restricted states immediately, and they will already be positioned for PPWR compliance in August 2026.

What “PFAS-free” actually means for molded fiber tableware

Sugarcane bagasse tableware is made from plant fiber pulp, water and heat. The base material itself contains no intentionally added PFAS. The question is what happens during production.

Historically, many molded fiber manufacturers added fluorinated chemicals — first C8 chemistry such as PFOA, later shorter-chain fluorotelomers — to the pulp or as a surface coating to repel oil and grease. Those additives are the entire reason PFAS appears in this product category. PFAS are persistent, bioaccumulative and extremely stable, which is what made them effective at repelling grease and what makes them a regulatory target today.

When a supplier says “PFAS-free,” it should mean three things:

• No fluorinated additives in the pulp formulation — no in-pulp oil repellents, wet-strength agents or release agents built on fluorinated chemistry
• No PFAS-based surface coatings applied after molding
• Production lines are kept separate from lines that use fluorinated chemistry, or fully validated and cleaned after any changeover

The residual fluorine nuance

Trace amounts of fluorine can still be detected in some plant-fiber products even without any intentional PFAS use, because bagasse and recycled fiber can carry residual fluorine from soil, water or upstream processing. This is why the verification method matters as much as the claim.

A serious supplier will explain the difference between “no intentionally added PFAS” and a measured limit. California’s AB 1200 convention — 100 ppm total fluorine as the screening threshold — is now widely used by importers as a practical, defensible benchmark even outside California. If a supplier’s product measures well below that threshold with a current, accredited test, the claim has substance.

Step 1: Understand what each certification does and does not prove

This is where most buyers make their first mistake. Several certifications are commonly cited in PFAS discussions, but they measure different things.

• BPI certification (ASTM D6400) proves the product composts in an industrial facility. It does not certify that the product is PFAS-free. A BPI-certified product can still contain PFAS.
• OK Compost HOME and OK Compost INDUSTRIAL (TÜV Austria) certify compostability, including limits on heavy metals and other substances. They are strong credentials, but again, ask to see the underlying test data rather than assuming.
• FDA compliance documentation (for example, compliance with 21 CFR 176.170 for paper and paperboard in contact with aqueous and fatty foods) is the relevant US food-contact standard. Your supplier should provide a Declaration of Compliance naming the specific materials and any food-contact additives used.
• LFGB / BfR compliance is the German and widely accepted EU benchmark for food-contact safety of paper and board products.
• BRCGS Grade A certification is a site-level quality and food-safety credential common among leading molded fiber producers. It tells you the factory runs disciplined systems; it says nothing about fluorine chemistry.

Takeaway
Treat certifications as the entry ticket, then verify PFAS separately with laboratory analysis. A logo on a website is marketing; a test report with a lab name and a method is evidence.

Step 2: Demand laboratory test reports, not just certificates

Certificates are issued once. Test reports are issued for every batch or product family and show actual measured values. For PFAS verification, request the following:

• Total fluorine screening using combustion ion chromatography (EN 14582) or the dedicated food-packaging method ASTM D8351. This is the first-line test that flags whether fluorine chemistry is present at all, and it is the method behind the 100 ppm screening threshold used in California’s AB 1200 framework.
• Targeted PFAS analysis using LC-MS/MS, typically covering 20 or more individual PFAS compounds. US laboratories commonly run EPA Method 533 (25 compounds) or EPA Method 537.1 (18 compounds); international testing often references ISO 25101.
• Testing from an accredited laboratory (ISO/IEC 17025), such as SGS, Intertek, TÜV, Eurofins or an equivalent national lab. Ask for the lab’s accreditation scope to confirm the tests were actually in scope.
• Test date and batch linkage: a report from three years ago on a different product line is not evidence for the product you are buying today. The report should name the product family, the batch or production period, and the sample taken.

Red flag
If a supplier sends a single PDF certificate with no lab name, no method and no measured values, treat it as a red flag, not proof.

Step 3: Verify certifications on official registries

Anyone can print a logo. Verify credentials on the certifying body’s own registry — this five-minute check frequently exposes suppliers who display certification logos they do not hold:

• BPI: searchable product directory at products.bpiworld.org
• OK Compost: certified products are listed by TÜV Austria in its official product database — confirm the exact product family, not just the company name
• FDA: check the supplier’s food facility registration and the applicable food-contact substance listings
• BRCGS: directory at directory.brcgs.com for sites holding BRC certification

When you check a registry, note the certificate number, the product family listed, and the expiry or re-audit date, and ask the supplier to confirm these match the SKUs you are buying.

Step 4: Ask about the production process itself

PFAS-free is a process attribute, not just a test result. In your RFQ or audit questionnaire, ask the supplier:

• What oil and grease resistance chemistry do you use, and is it fluorinated or fluorine-free?
• Do you use in-pulp fluorine-free oil repellents or fluorinated surface treatments? Can you name the additive suppliers?
• Do you maintain separate production lines or validated changeover procedures between fluorinated and non-fluorinated products?
• Do you hold food safety management certifications such as BRC Grade A, ISO 22000 or FSSC 22000, and can you share the latest audit report?
• Can you provide batch traceability from raw fiber to finished SKU?
• What is your typical test frequency for total fluorine and targeted PFAS — per batch, per quarter, or only on request?

The answers separate manufacturers who engineered PFAS-free production from suppliers who simply stopped adding fluorine and hoped no one would test.

Step 5: Check supply chain and dual-source structure

A PFAS test report is only as reliable as the production system behind it. Two supply chain questions matter in 2026:

• Single-source risk: if a supplier has only one plant in one country, a regulatory change or a shipping disruption can cut off your certified PFAS-free supply with no fallback.
• Tariff and duty structure: for US buyers, suppliers with production in Thailand benefit from preferential tariff treatment compared with China-origin goods, while China-based lines offer scale and cost advantages. A dual-base structure — for example, Chinese factories for volume plus a Thailand factory for US tariff efficiency — gives importers both price leverage and supply security.

Ask where the product you are buying will actually be manufactured, and make sure the PFAS test documentation matches the producing plant. A certificate from a sister factory is not evidence for another factory’s output.

Building your PFAS documentation file

Once a supplier passes the checks above, keep a structured documentation file for each product family you source. A complete file lets you answer any customer or regulator question without chasing the factory:

• Certificate of Analysis (COA) per shipment, naming the product family, batch and production date
• Latest lab test reports: total fluorine screening and targeted PFAS analysis, with the lab name, method and accreditation number visible
• Certification copies (BPI, OK Compost, FDA Declaration of Compliance, BRC certificate) with certificate numbers and expiry dates
• Registry screenshots with the date you verified them, so the evidence trail is provable
• Audit summaries for BRC Grade A, ISO 22000 or FSSC 22000, plus the supplier’s changeover or line-separation policy

Review this file on a fixed cadence — quarterly for regulatory categories, given how fast PFAS rules are moving. When a supplier updates a test method, a certification or a production site, ask for the updated documents before your next order, not after.

Red flags checklist

• Supplier claims “PFAS-free” but cannot produce a lab test report
• Certification logos that do not appear on the certifying body’s registry
• Vague wording such as “low PFAS” or “PFAS-free coating” (a coating that is PFAS-free is still a coating; ask what it is)
• Test reports without lab name, method, accreditation number or batch reference
• No answer on whether fluorinated products are made on the same line
• Marketing pages with no technical documentation to support claims
• COA (certificate of analysis) that does not name the product family or batch
• Test documentation from a different factory than the producing plant

How Zhongxin approaches PFAS-free production

Zhongxin (603091.SH) manufactures sugarcane bagasse tableware with an annual capacity of 200,000 tons across 3 production bases, ships to 80 countries, and operates a fluorine-free technology platform. Our molded fiber products use an in-pulp, fluorine-free oil repellent system developed for oil resistance up to 90°C, and our heat-resistant fluorine-free molding technology covers the range from plates and bowls to clamshells and trays. 100% of our standard production runs without fluorinated surface coatings.

Our production system is built around the kind of evidence this guide asks for:

• FDA compliance documentation for food contact
• BPI certification (verifiable on the BPI registry) and TÜV Austria OK Compost HOME and INDUSTRIAL certifications
• LFGB / BfR food-contact compliance
• BRC Grade A site certification, ISO 22000 and ISO 9001
• Batch-level traceability and laboratory test reports from accredited third-party labs (ISO/IEC 17025)
• Dual-base supply: Chinese plants for scale plus a Thailand plant that supports tariff-efficient supply into the US market

Because every claim needs to be checkable, we publish verification guides showing exactly how to confirm our certifications on official registries, and we make product and test documentation available to procurement teams before sample orders. Our engineering team of 136 R&D engineers works on fluorine-free formulations and molding processes — the chemistry behind the 90°C oil-resistance performance is a designed system, not an afterthought.

Your verification checklist for the next RFQ

1. Confirm the product family you are buying has its own PFAS test report, not a generic company claim
2. Request total fluorine screening (EN 14582 / ASTM D8351) plus targeted PFAS analysis (EPA 533/537.1 or ISO 25101) from an ISO/IEC 17025 accredited lab
3. Check BPI and OK Compost registries for the specific SKU numbers
4. Ask for FDA Declaration of Compliance and BRC audit summary
5. Confirm production-line separation from fluorinated chemistry
6. Match the test documentation to the actual producing plant (China vs Thailand)
7. Request samples and test them before committing to volume

Frequently Asked Questions

The bottom line

PFAS compliance is not a differentiator anymore; it is the entry requirement. US state laws already restrict PFAS in food packaging, the FDA phase-out has removed PFAS grease-proofing from the US market, and the EU’s PPWR adds a hard August 2026 deadline. The suppliers who win in 2026 will be the ones who can prove PFAS-free production on paper — with current lab reports, verifiable certifications and transparent process documentation — not just claim it on a landing page.
