The Basics of FDA Food Contact Regulations

Anything that comes into contact with food — whether for milliseconds during processing or for weeks in storage — falls under FDA regulation in the United States. This includes the obvious categories like food packaging, dishware, and cooking utensils, plus less obvious categories like conveyor belts in food plants, equipment seals, lubricants used near food, and cleaning chemicals that might leave residues. The regulatory framework that governs all of this is collectively called Food Contact Substances (FCS) regulation, administered by the FDA’s Center for Food Safety and Applied Nutrition.

For compostable foodware suppliers and the buyers who purchase from them, the FDA framework matters because it determines what products can legally be used in food service. Compostability certifications (BPI, TÜV) address whether a product breaks down properly at end-of-life. FDA compliance addresses whether the product is safe to use with food in the first place. These are independent regulatory tracks, and a product needs to satisfy both.

This article walks through the basics of the FDA food contact framework — what categories exist, what manufacturers must demonstrate, how compostable foodware fits in, and what buyers should ask suppliers about compliance.

The legal basis

FDA’s authority over food contact substances comes from the Federal Food, Drug, and Cosmetic Act (FD&C Act), specifically Section 409. The Act requires that food additives — defined broadly to include substances that may become components of food through migration from packaging or processing equipment — be approved by FDA before commercial use, unless they qualify for one of several exemptions.

The framework has evolved substantially. The original 1958 Food Additives Amendment created a slow approval process where each new food contact material required a Food Additive Petition (FAP) — a multi-year regulatory submission. In 1997, recognizing that the FAP process couldn’t keep pace with material innovation, Congress created the Food Contact Notification (FCN) process, which moved most new food contact substances to a notification rather than approval framework.

Today, a manufacturer can introduce a new food contact substance through several pathways:

1. Threshold of Regulation (TOR) exemption — for very low-migration substances
2. Generally Recognized as Safe (GRAS) determination — for substances with established safety records
3. Food Contact Notification (FCN) — the standard pathway for new materials
4. Food Additive Petition (FAP) — the legacy slow-track approval pathway, rarely used today
5. Prior sanctioning — for materials approved before 1958 under earlier regulatory frameworks

Each pathway has different requirements, timelines, and costs. The choice depends on the material, its intended use, and the migration profile.

What “food contact” actually means

The FDA defines food contact substance broadly. A substance qualifies if it’s “intended for use as a component of materials used in manufacturing, packing, packaging, transporting, or holding food, if such use is not intended to have a technical effect in such food.”

In practice, this includes:

• Direct food contact items: packaging films, containers, cups, plates, utensils
• Indirect food contact items: equipment surfaces, conveyor belts, gaskets, sealants in food processing facilities
• Processing aids: lubricants, antifoam agents, mold release agents that may transfer to food
• Cleaning and sanitizing chemical residues that may remain on food contact surfaces

The breadth means that a product like a compostable food container is regulated not just for its overall composition but for every individual chemical or polymer component that might migrate into food. A bagasse container with PLA coating must demonstrate FDA compliance for the bagasse fiber, the PLA polymer, the binders used in molding, the colorants if any, and the coating chemistry.

The migration concept

Central to FDA food contact regulation is the concept of migration — the movement of substances from the packaging into the food. The FDA’s safety assessment hinges on what migrates, how much, and what its toxicological profile is.

Migration depends on several factors:

• Contact temperature — hot foods cause more migration than cold; the differential can be 10-100x
• Contact time — longer contact means more migration; the relationship is roughly proportional for diffusion-controlled migration
• Food type — fatty foods absorb more from many polymers; aqueous foods absorb less; acidic foods can extract certain components more aggressively
• Surface area — larger contact area means proportionally more migration into the same food volume
• Polymer composition — different materials have different migration profiles

For each food contact material, FDA requires migration testing under standardized conditions designed to represent typical or worst-case use. The tests use food simulants (water, fatty food simulants, acidic food simulants) at temperatures and durations relevant to the intended use.

The acceptable migration limit depends on the toxicological profile of what’s migrating. Generally:

• Substances with no toxicological concern can migrate at higher levels
• Substances with toxicological concern have specific limits, often expressed in micrograms per kg of food
• Substances with significant toxicological concern (carcinogens, reproductive toxins) face very low limits or prohibition

How compostable foodware fits the framework

Compostable foodware materials face the same FDA framework as conventional foodware. The fact that a product is compostable doesn’t change its food contact regulatory requirements.

For specific compostable materials, here’s the typical FDA pathway:

PLA (polylactic acid): Has multiple FCN approvals covering various applications including hot beverage cups, cold cups, and food containers. Specific FCN numbers cover specific suppliers and intended uses. PLA migration profiles are generally favorable because the polymer is relatively low-migration at typical use temperatures.

PHA (polyhydroxyalkanoate): Has FCN approvals from several suppliers. Newer than PLA in commercial use; the FCN history is shorter but the framework is the same.

PBAT (polybutylene adipate terephthalate): Has FCN approvals when used in food contact applications. Often used in blends with PLA for flexible film applications like compostable bags.

Bagasse (sugarcane fiber): Generally falls under prior-sanctioned materials for paper and paperboard food contact uses. Bagasse-based products typically don’t require new FCN submissions when manufactured to standard paper industry specifications.

Cellulose film and pulp products: Long-established food contact materials with clear regulatory pathways under prior sanctioning.

Wood-based products (wooden cutlery, bamboo, palm leaf): Generally compliant under existing wood-product food contact provisions when manufactured to standard specifications.

The pattern: established compostable materials with industry track records have clear FDA pathways. Newer or novel materials require more substantial regulatory work.

What manufacturers must demonstrate

For each food contact substance, a manufacturer must demonstrate:

1. Identity — what is the substance chemically? Pure compounds, polymer specifications, blend compositions.
2. Intended use — what types of food will it contact? At what temperatures? For how long?
3. Migration data — laboratory testing under FDA-specified conditions showing what migrates and at what levels.
4. Toxicological data — safety information for the substance and any migrants. The depth required scales with expected exposure level.
5. Manufacturing controls — quality controls demonstrating that the commercial product matches the tested formulation.

The data package for an FCN typically runs hundreds of pages. The migration testing alone can cost $50,000-200,000 for a comprehensive evaluation. Toxicological assessment adds another $100,000-500,000 if new studies are required (less if the substance has existing toxicology data).

For smaller suppliers, working with established manufacturers who already hold FCNs is the practical path — the supplier doesn’t need to file their own FCN if their product uses an established food contact substance under existing authorizations.

Common buyer questions and how to address them

When evaluating compostable foodware suppliers, B2B buyers should ask specific questions about FDA compliance:

“Is this product FDA compliant for food contact?”
This is the basic question. Every supplier should be able to answer yes for any product they sell into the U.S. food contact market and should be able to provide documentation supporting the claim.

“Under what regulatory pathway is the product compliant?”
The supplier should be able to identify FCN numbers, prior sanctioning provisions, or other specific bases for compliance. Vague answers (“our material is FDA compliant”) without specifics suggest the supplier may not actually understand the regulatory basis.

“Has the product been tested for migration under conditions relevant to my use case?”
For unusual applications (very hot foods, prolonged contact, fatty or acidic foods), buyers should verify migration testing covers the relevant conditions. A product tested only for cold beverages may not be compliant for hot food applications.

“Are there any specific use restrictions?”
Some food contact authorizations include restrictions — only for certain food types, only at certain temperatures, only for limited contact duration. Buyers using products near the edges of authorization conditions should verify compliance specifically.

“Do you have a Letter of No Objection or similar from the FDA?”
For older substances, FDA may have issued specific guidance letters confirming compliance status. These provide additional documentation for buyer files.

The PFAS situation

The most significant recent development in FDA food contact regulation involves PFAS (per- and polyfluoroalkyl substances) — the family of chemicals that includes PFOA, PFOS, and the longer-chain compounds historically used in greaseproof food packaging.

FDA has been progressively restricting PFAS in food contact applications. In 2024, FDA announced that all PFAS-based grease-proofing agents would be voluntarily phased out of food contact use. This affects:

• Microwave popcorn bags (historically heavy PFAS users)
• Fast food wrappers and grease-resistant boxes
• Take-out containers with grease resistance
• Some compostable foodware that historically used PFAS for grease resistance

Several U.S. states (California, Washington, New York, Vermont, Connecticut, others) have passed laws banning PFAS in food packaging beyond what FDA requires. The patchwork of federal and state regulation means that PFAS-free compliance is increasingly required for any food contact packaging sold across multiple states.

For compostable foodware buyers, this means that “PFAS-free” should be a specific verified attribute, not assumed. Some compostable products historically contained PFAS for grease resistance; the industry has been phasing out but legacy products may still exist in supply chains.

Bisphenols and other regulated migrants

Beyond PFAS, several other migrants face specific regulatory attention:

• Bisphenol A (BPA): Long-established food contact substance facing increasing regulatory scrutiny. Restricted in baby bottles, sippy cups, and infant formula packaging at federal level. Some states have additional restrictions.
• Phthalates: Used as plasticizers in some food contact materials. Several phthalates are restricted; others are under review.
• Heavy metals: Lead, cadmium, mercury, arsenic — all face strict migration limits across food contact applications.
• Nitrosamines: Specific carcinogens that can form during the manufacturing of some rubber products used in food contact applications.

For most compostable foodware, these chemical-specific concerns are less acute than for conventional plastics — the bio-based polymers used in compostable products generally don’t contain these compounds. But verification matters; some compostable products use additives, colorants, or coatings that could contain regulated substances.

Recordkeeping and traceability

FDA enforcement of food contact regulations relies substantially on recordkeeping. Manufacturers must maintain records of:

• Composition specifications for each food contact substance
• Migration testing results
• Toxicological assessments supporting compliance
• Quality control data for commercial production
• Regulatory submissions and FDA correspondence

For multi-tier supply chains (raw material supplier → polymer compounder → product manufacturer → distributor → end user), each tier maintains records relevant to their level of the chain. A product manufacturer relies on certifications from upstream polymer suppliers; the polymer supplier maintains the underlying data on their material.

Buyers should be able to obtain Certificates of Compliance from suppliers documenting FDA compliance status for products they purchase. These certificates typically reference the underlying regulatory pathway (FCN number, prior sanctioning provision) and confirm conformance to specifications.

What this means for international supply chains

Compostable foodware often involves international supply chains — raw materials from one country, polymer production in another, finished product manufacturing in a third, distribution and use in a fourth. FDA compliance applies to anything sold in U.S. food contact markets regardless of where manufacturing occurs.

For buyers sourcing from international suppliers, additional verification is often warranted:

• Confirm the manufacturer understands FDA requirements specifically (not just EU food contact requirements, which are similar but not identical)
• Verify documentation is in English and references U.S. regulatory pathways
• Consider third-party laboratory testing for high-volume or high-risk applications
• Request material declarations covering all components, not just the headline polymer

Reputable international suppliers serving the U.S. market understand these requirements and provide appropriate documentation. Suppliers without clear FDA compliance documentation should be approached with caution regardless of price.

The FCN process in practical detail

For manufacturers introducing a new food contact substance, the Food Contact Notification (FCN) process is the standard pathway. Understanding what this involves helps buyers gauge supplier sophistication and timeline expectations.

The FCN submission contains:

• Identity section with full chemical characterization, molecular structure, manufacturing process description, and impurity profile
• Intended use section specifying food types contacted, temperatures, durations, surface-to-volume ratios, and intended applications
• Migration testing data under FDA-prescribed test conditions using appropriate food simulants
• Toxicology section including any relevant studies on the substance and on potential migrants; the depth required scales with expected dietary exposure
• Environmental assessment evaluating environmental impact of manufacturing and disposal
• Manufacturing controls describing quality systems ensuring commercial product matches the tested formulation

After submission, FDA has 120 days to either object or allow the notification to take effect. Most FCNs are not objected to within the 120-day window, becoming effective at day 121. FDA may extend the review period if additional information is needed, which can push timelines to 6-12 months.

A manufacturer holding an effective FCN can use that substance commercially within the conditions specified. Other manufacturers wanting to use the same substance must either rely on the original FCN holder’s authorization (with permission), file their own FCN, or rely on a different regulatory pathway.

For compostable foodware suppliers, the FCN structure means that material innovation in the compostable space requires substantial regulatory investment before commercialization. This is one reason new compostable polymer types appear slowly — the regulatory pathway is real work even when the underlying chemistry is sound.

The bottom line for buyers

FDA food contact regulation is real, comprehensive, and applies to compostable foodware just as it applies to conventional packaging. For buyers, the practical implications:

• Verify compliance documentation from suppliers as part of vetting
• Ask specific questions about regulatory pathways and use restrictions
• Be especially careful with PFAS-free claims — verify rather than assume
• Consider third-party verification for high-volume or unusual applications
• Maintain records of supplier compliance documentation in your purchasing files

A compostable product that’s not FDA compliant for food contact isn’t legally usable in U.S. food service regardless of how good its compostability profile is. The two regulatory tracks (FDA food contact + compostability certification) both matter and both need to be verified for any product entering food contact applications.

Get the FDA piece right and the rest of the procurement decision can focus on the compostability, performance, and operational factors that matter for your specific application. Skip it and you risk both regulatory and reputational issues that no compostability story can offset.
