Food Contact Notification (FCN), GRAS, Prior Sanction & Threshold of Regulation Pathways — Food-contact materials (China → United States (FDA 21 CFR 174-179))?

Before exporting to the US, Chinese manufacturers must map every substance in their food-contact article to a valid US compliance pathway (21 CFR listing, effective FCN, GRAS, prior sanction, or threshold of regulation). No Chinese domestic approval substitutes for this verification. The FCN database and 21 CFR 170.39 exemption list are publicly available on FDA's website.

Material-Specific Rules — Adhesives & Coatings (21 CFR 175), Paper & Paperboard (21 CFR 176), Polymers (21 CFR 177), Adjuvants & Production Aids (21 CFR 178) — Food-contact materials (China → United States (FDA 21 CFR 174-179))?

Chinese manufacturers must verify every substance in adhesives, coatings, paper/paperboard, polymers, and adjuvants against the specific 21 CFR subpart applicable to that material type. Substance lists under GB 4806/GB 9685 are not equivalent to 21 CFR 175-178 lists. Cross-checking each formulation component against the applicable CFR subpart — or securing an effective FCN — is required before US market entry.

Extraction & Migration Testing + Compliance Documentation (21 CFR 176.170, FDA Guidance) — Food-contact materials (China → United States (FDA 21 CFR 174-179))?

FDA does not issue a premarket compliance certificate for food-contact materials — this is a critical difference from some other regulatory systems. Manufacturers self-certify compliance and retain a compliance file. US importers routinely request written compliance statements citing the 21 CFR regulatory basis. Chinese GB 31604 test reports do not substitute for 21 CFR-based test data; re-testing to applicable 21 CFR extraction protocols may be required.

Food-Contact Substance Regulatory Status — FD&C Act §409 & 21 CFR 174-179 — Food-contact materials (China → United States (FDA 21 CFR 174-179))?

Compliance with 21 CFR 174-179 is mandatory for food-contact articles placed on the US market. FDA issues no premarket certificate — the manufacturer self-certifies compliance. Chinese GB 4806 approval does not substitute. Each substance in the food-contact article must be individually verified against the applicable 21 CFR regulation, effective FCN database, GRAS inventory, or threshold of regulation.

State-Level Requirements — California Prop 65, PFAS Bans & Food-Contact Labelling — Food-contact materials (China → United States (FDA 21 CFR 174-179))?

US state requirements layer on top of FDA federal requirements and are not optional for products sold in those states. California Prop 65 warnings are required for products migrating listed chemicals above MADLs. An expanding set of states ban intentionally added PFAS in food packaging — Chinese manufacturers using fluoropolymer treatments or coatings must assess compliance with the applicable state laws for their distribution footprint. No Chinese domestic standard substitutes for US state-level requirements.

Compliance item	Common China baseline	United States (FDA 21 CFR 174-179)	Gap / action	Source + verification date
Food Contact Notification (FCN), GRAS, Prior Sanction & Threshold of Regulation Pathways	China operates a positive-list system under GB 9685-2016 (Additives for use in food-contact materials and articles) and the GB 4806 series. There is no FCN pathway in China — a new substance not listed in the positive lists requires either: (a) amendment of the relevant national standard (a process administered by NHC, typically taking years), or (b) a raw material extension application. GRAS equivalents do not exist as a self-determination mechanism in China. The system is more restrictive in the sense that substances are not permitted unless explicitly listed, but the listing process is also less transparent and less predictable than the US FCN process.GB 9685-2016 — Food safety national standard: Additives for use in food-contact materials and articles (NHC) GB 4806.1-2016 — General requirements for food-contact materials and articles	FDA provides four compliance pathways for food-contact substances (FCS): (1) Food Contact Notification (FCN) — the main modern pathway since 1997; a manufacturer or supplier submits a notification to FDA demonstrating safety at the intended use level; the FCN becomes effective 120 days after receipt unless FDA objects. FCNs are use-specific and notifier-specific — only the notifier may rely on the FCN. (2) GRAS (Generally Recognized As Safe) — substances with a long history of safe use or scientific consensus; GRAS status may be self-determined by the manufacturer (voluntary FDA notification since 1997). (3) Prior-sanctioned substances — substances approved by FDA or USDA before January 1, 1958; listed in 21 CFR 181. (4) Threshold of Regulation (21 CFR 170.39) — for substances migrating at or below 0.5 ppb in food (or 1.5 mcg/person/day dietary exposure) from non-carcinogenic substances with no significant safety concern; manufacturer files a threshold exemption request. FDA's FCN database is publicly searchable.21 CFR 170.39 — Threshold of regulation for substances used in food-contact articles 21 CFR Part 181 — Prior-sanctioned food ingredients FD&C Act §409(h) — Food Contact Notification program FDA Food Contact Substance Notification Program	Chinese manufacturers exporting food-contact articles to the US cannot rely on their domestic positive-list approvals. For each substance: (1) check the FDA FCN database for an effective FCN at the intended use — note FCNs are notifier-specific, so a third party cannot rely on another company's FCN; (2) check 21 CFR 174-179 for a listing; (3) evaluate GRAS status; (4) evaluate threshold of regulation eligibility. If none applies, a new FCN submission or GRAS determination is required before US market entry — a process that takes months to years. The threshold-of-regulation route (0.5 ppb migration) may be available for some low-migration substances and is faster but requires migration data.[INFORMATIONAL] Before exporting to the US, Chinese manufacturers must map every substance in their food-contact article to a valid US compliance pathway (21 CFR listing, effective FCN, GRAS, prior sanction, or threshold of regulation). No Chinese domestic approval substitutes for this verification. The FCN database and 21 CFR 170.39 exemption list are publicly available on FDA's website.

Material-Specific Rules — Adhesives & Coatings (21 CFR 175), Paper & Paperboard (21 CFR 176), Polymers (21 CFR 177), Adjuvants & Production Aids (21 CFR 178)	China's GB 4806 series covers the same material types with material-specific standards: GB 4806.2-2016 (rubber materials and articles), GB 4806.3-2016 (coatings and coating layers), GB 4806.4-2016 (ceramic and enamel), GB 4806.5-2016 (glass), GB 4806.6-2016 (metal materials and articles), GB 4806.7-2016 (plastic materials and articles — equivalent to 21 CFR 177 for plastics), GB 4806.8-2016 (paper and paperboard — equivalent to 21 CFR 176), GB 4806.9-2016 (metal materials — stainless steel), GB 4806.10-2016 (paint and coatings), GB 4806.11-2021 (nitrile rubber). GB 9685-2016 provides the permitted additives list across all material types. Each GB 4806.x standard includes migration limits for specific substances.GB 4806.7-2016 — Food safety national standard: Plastic materials and articles for food contact GB 4806.8-2016 — Food safety national standard: Paper and paperboard for food contact GB 9685-2016 — Food safety national standard: Additives for use in food-contact materials and articles	21 CFR Parts 175-178 each address a specific category of food-contact material, listing permitted substances and conditions of use: Part 175 (Indirect Food Additives: Adhesives and Components of Coatings) — covers adhesives (175.105), surface lubricants (175.125), and coatings used in contact with food; Part 176 (Indirect Food Additives: Paper and Paperboard Components) — covers paper/paperboard in dry, aqueous, and fatty food contact, including defoaming agents (176.170 extraction protocols for aqueous simulation); Part 177 (Indirect Food Additives: Polymers) — covers common polymers including polyethylene (177.1520), polypropylene (177.1520), PET (177.1630), nylon (177.1500), LDPE, HDPE, polystyrene (177.1640), and many others; Part 178 (Indirect Food Additives: Adjuvants, Production Aids, and Sanitizers) — covers antioxidants, colorants for polymers, defoamers, and sanitizers. Each subpart specifies permitted substances, purity requirements, and conditions of use (e.g., food type contact categories, temperature limits).21 CFR Part 175 — Indirect Food Additives: Adhesives and Components of Coatings 21 CFR Part 176 — Indirect Food Additives: Paper and Paperboard Components 21 CFR Part 177 — Indirect Food Additives: Polymers 21 CFR Part 178 — Indirect Food Additives: Adjuvants, Production Aids, and Sanitizers	The permitted substance lists under 21 CFR 175-178 and the Chinese GB 4806/GB 9685 lists do not fully overlap. A substance listed in GB 9685 may not appear in the relevant 21 CFR part, and vice versa. Key practical gaps for Chinese exporters: (1) Plastic colorants and additives — China's GB 9685 list of permitted colorants differs from those acceptable under 21 CFR 178; (2) Adhesives — 21 CFR 175.105 and 175.300 (resinous/polymeric coatings) require specific polymer types and purity thresholds not directly mapped from Chinese equivalents; (3) Paper/paperboard — 21 CFR 176.170 extraction tests use specific food-simulating solvents and conditions that differ from GB 31604 protocols; (4) Polymer additives — antioxidants and UV stabilizers commonly used in China (e.g., certain hindered amine light stabilizers) may not be listed in 21 CFR 178. Each substance and formulation must be individually cross-checked.[INFORMATIONAL] Chinese manufacturers must verify every substance in adhesives, coatings, paper/paperboard, polymers, and adjuvants against the specific 21 CFR subpart applicable to that material type. Substance lists under GB 4806/GB 9685 are not equivalent to 21 CFR 175-178 lists.

Extraction & Migration Testing + Compliance Documentation (21 CFR 176.170, FDA Guidance)	China's migration testing framework is GB 31604 series: GB 31604.1-2015 (general provisions for migration testing), with specific test methods for individual substances (GB 31604.x series covering over 50 analytes including formaldehyde, bisphenol A, heavy metals, etc.). China uses food-simulating solvents similar in concept (water, 4% acetic acid, 10% ethanol, isooctane/olive oil for fatty food simulants) but with different test conditions. GB 31604 migration tests are conducted by CNAS-accredited or CMA-certified laboratories in China. Chinese test reports from these labs are NOT automatically accepted by FDA or US importers as evidence of US compliance — the test methods and regulatory basis differ.GB 31604.1-2015 — Food safety national standard: General provisions for migration testing of food-contact materials and articles GB 31604 series — Specific migration test methods (50+ individual substance methods)	FDA's approach to migration/extraction testing differs from the EU's specific migration limits (SMLs) framework. The US system: (1) For substances listed in 21 CFR 174-178, the regulation itself specifies the permitted use conditions (food types, temperature, contact duration) and may specify extractability limits or extraction test protocols. 21 CFR 176.170 is the primary extraction protocol for paper and paperboard in contact with aqueous and fatty foods, specifying food-simulating solvents (distilled water, 3% acetic acid, 8% alcohol, n-heptane or hexane) and conditions. (2) For FCN submissions, the notifier must provide migration/extraction data demonstrating that the dietary exposure from the substance at its intended use level is safe. (3) FDA does not issue a premarket compliance certificate — manufacturers prepare and retain a compliance file (including regulatory basis, formulation details, test data if applicable) and are responsible for compliance at the point of import. US Customs and Border Protection (CBP) and FDA conduct import surveillance; non-compliant shipments may be detained or refused.21 CFR 176.170 — Components of paper and paperboard in contact with aqueous and fatty foods (extraction protocols) 21 CFR 174.5 — General provisions applicable to indirect food additives FD&C Act §801 — Import detention and refusal authority	The key documentation gap is that FDA issues no premarket certificate. Chinese exporters accustomed to obtaining a government-issued certificate for each product must understand that US compliance is self-certified by the manufacturer. US importers (especially major retailers) typically require: (1) a written compliance statement referencing the specific 21 CFR basis or FCN number; (2) formulation details or a summary bill of materials; (3) test reports conducted to FDA-relevant protocols (21 CFR 176.170 or equivalent) if migration data is needed; (4) country of origin documentation. Migration test reports generated to GB 31604 protocols are generally not accepted as direct evidence of 21 CFR compliance due to differences in food simulants, test temperatures, and contact time parameters.[INFORMATIONAL] FDA does not issue a premarket compliance certificate for food-contact materials — this is a critical difference from some other regulatory systems. Manufacturers self-certify compliance and retain a compliance file. US importers routinely request written compliance statements citing the 21 CFR regulatory basis. Chinese GB 31604 test reports do not substitute for 21 CFR-based test data; re-testing to applicable 21 CFR extraction protocols may be required.

Food-Contact Substance Regulatory Status — FD&C Act §409 & 21 CFR 174-179	China's equivalent framework is the GB 4806 series of national food safety standards for food-contact materials and articles, administered by the National Health Commission (NHC) under the Food Safety Law. Key standards include GB 4806.1 (general requirements), GB 9685 (additives positive list), and material-specific standards GB 4806.2-10. The system uses positive lists: only listed substances are permitted. China's market regulator (SAMR/NHFPC) enforces GB 4806 compliance. Unlike the US, China does not have a food-contact notification pathway — substances not on the positive lists require a new national standard or a raw material extension application.GB 4806.1-2016 — Food safety national standard: General requirements for food-contact materials and articles GB 9685-2016 — Food safety national standard: Additives for use in food-contact materials and articles Food Safety Law of the People's Republic of China (2021 revision)	Under the Federal Food, Drug, and Cosmetic Act (FD&C Act) §409, any substance that migrates into food from packaging or processing equipment is regulated as a 'food additive' unless it is generally recognized as safe (GRAS), prior-sanctioned, or covered by a specific exemption. FDA's implementing regulations for indirect food additives are codified at 21 CFR Parts 174-179. A substance used in food-contact articles must either: (a) be listed in an applicable 21 CFR Part 174-179 regulation, (b) be covered by an effective Food Contact Notification (FCN), (c) qualify as GRAS or prior-sanctioned, or (d) fall below the threshold of regulation (21 CFR 170.39). FDA does NOT issue a premarket certificate or compliance mark for food-contact materials — the manufacturer bears sole legal responsibility to ensure compliance before placing products on the US market.FD&C Act §409 (21 U.S.C. §348) — Food Additives 21 CFR Part 174 — Indirect Food Additives: General 21 CFR Parts 175-179 — Indirect Food Additives: specific material types	The fundamental regulatory gap is that FDA's system is substance-by-substance and use-specific, whereas China's GB 4806 is a positive-list framework. A substance approved under GB 9685 or GB 4806.x for a given end-use in China is NOT automatically permitted under 21 CFR 174-179 in the US, and vice versa. Chinese exporters must independently verify each substance in their food-contact article against the applicable 21 CFR part, active FCN database, or GRAS inventory. There is no mutual recognition agreement between FDA and Chinese food-contact regulators. Critically, FDA issues no premarket certificate — the exporter's compliance declaration is the only documentation; US importers and retailers typically require a written compliance statement from the manufacturer.[INFORMATIONAL] Compliance with 21 CFR 174-179 is mandatory for food-contact articles placed on the US market. FDA issues no premarket certificate — the manufacturer self-certifies compliance. Chinese GB 4806 approval does not substitute.

State-Level Requirements — California Prop 65, PFAS Bans & Food-Contact Labelling	China does not have a state-level regulatory framework analogous to US state laws. There is no Chinese equivalent to Proposition 65 or state-level PFAS packaging bans. China's national GB 4806 standards include migration limits for certain heavy metals (lead, cadmium, chromium, nickel, arsenic) and set requirements on specific substances such as DEHP in plastic articles (subject to GB 4806.7 and GB 9685 listing). China does not have a national PFAS-in-food-packaging ban as of 2026, though PFAS restrictions are evolving under China's chemicals management framework (MEE/ECHA-analog processes).GB 4806.7-2016 — Plastic materials and articles for food contact (heavy metal migration limits) GB 9685-2016 — Additives for use in food-contact materials and articles (DEHP and phthalate restrictions)	Beyond federal FDA requirements, US states impose additional obligations on food-contact materials: (1) California Proposition 65 (Safe Drinking Water and Toxic Enforcement Act of 1986) — businesses with 10 or more employees must provide a clear and reasonable warning before knowingly exposing Californians to listed chemicals. Common food-contact-relevant Prop 65 chemicals include lead, cadmium, DEHP (a phthalate plasticizer), and bisphenol A (BPA). No-observed-effect levels (NOELs) and maximum allowable dose levels (MADLs) apply; products that migrate these chemicals above the MADL require a Prop 65 warning or reformulation. (2) PFAS (per- and polyfluoroalkyl substances) bans in food packaging — multiple US states have enacted or scheduled bans on intentionally added PFAS in food packaging: California (AB 1200, effective January 2023 for cookware disclosure, food packaging PFAS ban effective January 2025), Washington (effective January 2023), Maine (effective January 2030), New York (effective December 2022 for certain packaging), Minnesota, Colorado, and others. Federal action is pending. (3) Labelling — there is no federal mandate for food-contact material composition labelling, but California AB 1200 requires cookware manufacturers to disclose chemicals of concern on their websites and product labelling.California Proposition 65 (Safe Drinking Water and Toxic Enforcement Act of 1986), Health & Safety Code §25249.5 et seq. California AB 1200 (2021) — cookware PFAS disclosure and food packaging PFAS prohibitions Washington State HB 1694 (2021) — PFAS in food packaging ban Maine LD 1503 / 38 M.R.S. §1614 — PFAS in food packaging	Chinese exporters face two compounding gaps in the US state regulatory landscape: (1) Prop 65 — products containing or migrating Prop 65-listed substances (especially DEHP, BPA, lead, cadmium) above the MADL must carry a Prop 65 warning if sold in California. Many Chinese plastic and printed food-contact articles use phthalate plasticizers or heavy-metal-based pigments that may trigger Prop 65 obligations. Chinese domestic compliance with GB limits does not satisfy Prop 65 MADLs, which are set at lower levels. (2) PFAS — Chinese manufacturers using fluoropolymer coatings or PFAS-treated paper/paperboard for food packaging must verify product compliance with the expanding patchwork of state PFAS bans. Fluoropolymer non-stick coatings (PTFE, PFOA-free products) should be assessed against state-specific PFAS definitions, which vary. (3) No direct CN equivalent to state-level rules exists — Chinese manufacturers must research each target US state's requirements independently.[INFORMATIONAL] US state requirements layer on top of FDA federal requirements and are not optional for products sold in those states. California Prop 65 warnings are required for products migrating listed chemicals above MADLs. An expanding set of states ban intentionally added PFAS in food packaging — Chinese manufacturers using fluoropolymer treatments or coatings must assess compliance with the applicable state laws for their distribution footprint. No Chinese domestic standard substitutes for US state-level requirements.	California Office of Environmental Health Hazard Assessment (OEHHA)2026-06-12 · unverified
