The Basics of FDA Food Contact Regulations: A Foodservice Operator’s Compliance Guide

FDA food contact regulations govern materials that touch food in commercial foodservice — encompassing all packaging, utensils, containers, and surfaces in direct or indirect food contact. The regulatory framework has been in development since the original Federal Food, Drug, and Cosmetic Act (1938) and continues evolving as new materials enter foodservice. For B2B foodservice operators procuring compostable packaging — where novel bio-based materials raise specific compliance questions — understanding the FDA framework supports informed procurement and compliance documentation.

This guide is the working B2B reference on FDA food contact regulations from a foodservice procurement perspective.

What FDA Food Contact Regulations Cover

FDA’s food contact regulatory framework spans:

Direct food contact materials — anything in direct contact with food (containers, utensils, packaging surfaces).

Indirect food contact materials — materials that may transfer substances to food during processing, transport, or storage.

Food contact substances — chemical components that might migrate from packaging into food.

Manufacturing process aids — substances used in food production that may remain.

For foodservice packaging, the most relevant focus is direct and indirect food contact materials.

Regulatory Framework Components

Several FDA regulatory mechanisms govern food contact materials:

21 CFR (Code of Federal Regulations)

The codified federal regulations covering food contact substances:

21 CFR Part 174-178: Indirect food additives, including various food contact materials.

21 CFR Part 175-178: Specific food contact substance categories with detailed requirements.

Specific listing of approved substances with permitted use conditions.

Food Contact Notification (FCN) Program

For new food contact substances:

FCN process allows manufacturers to introduce new food contact substances.

Manufacturer submits notification demonstrating safety.

FDA review with response within 120 days.

Public listing of approved FCNs.

For compostable bioplastic materials, FCN approvals are critical for new substances entering foodservice.

Threshold of Regulation (TOR)

For substances at very low migration levels:

Below specific threshold, substances may not require formal FCN approval.

Streamlined regulatory pathway.

Generally Recognized as Safe (GRAS)

For substances with established safety:

GRAS substances generally accepted as safe based on scientific consensus.

Not subject to formal premarket approval.

Many traditional food contact substances fall under GRAS framework.

What This Means for Compostable Packaging

Compostable packaging materials must satisfy FDA food contact regulations:

PLA (Polylactic Acid)

PLA is FDA-approved for food contact:

Approved for direct food contact in 21 CFR.

Multiple PLA grades approved for various applications.

Major PLA suppliers (NatureWorks, Total Corbion) provide food-grade documentation.

For B2B procurement, food-grade PLA documentation should be available.

Bagasse Fiber

Bagasse fiber for foodservice has FDA approval:

Approved for food contact when manufactured to food-grade specifications.

Variability between manufacturers. Verify specific manufacturer’s food-grade certification per SKU.

Some bagasse may have additives affecting compliance status.

PHA (Polyhydroxyalkanoates)

PHA for food contact:

Approved for food contact in various FCN approvals.

Specific PHA variants have specific approval scope.

Verify per-SKU approval status for procurement.

Cellulose-Based Materials

Cellulose film and paper:

Generally approved for food contact.

Coatings may affect approval status. Some specialty coatings require separate approval.

Compostable Coatings

PFAS-free compostable grease-resistant coatings:

PFAS-based coatings have specific California restrictions despite FDA approval.

PFAS-free alternatives typically have appropriate FDA status.

Verify per-coating approval for procurement.

Specific Compliance Considerations

For B2B compostable packaging procurement:

Food-Grade Certification Documentation

Suppliers should provide:

Food-grade material certification for each SKU.

Manufacturing process documentation demonstrating food-safe practices.

Specific FDA regulatory citation (FCN number, 21 CFR section, GRAS basis).

Migration test data where applicable for the specific application.

Application-Specific Considerations

Different applications have different specific compliance considerations:

Hot food applications require materials approved for elevated-temperature contact.

Acidic food applications require materials approved for acidic conditions (pH<5).

Fatty food applications require materials approved for grease/fat contact.

Long-duration contact applications may have stricter requirements.

For procurement, match material approvals to actual application conditions.

Imported Material Considerations

For imported compostable packaging:

FDA approval requirement applies regardless of manufacturing location.

Import documentation should include FDA compliance documentation.

Some imported products may have foreign approvals that don’t translate to FDA acceptance.

Common Compliance Mistakes

Assuming compostable means food-safe. Compostability and food-safety are separate regulatory requirements.

Generic supplier claims without specific documentation. “FDA-approved” without specific regulatory citation has limited substantive value.

Not matching material to application. Some materials approved for general food contact aren’t approved for specific applications (high-temperature, acidic, etc.).

Assuming brand-level approval transfers to all SKUs. Verify per-SKU.

Documentation Recommendations

For B2B compostable packaging procurement compliance:

Per-SKU food-grade certification. Document specific SKU’s food contact compliance.

Specific regulatory citation. FCN number, 21 CFR section, GRAS basis — whatever applies.

Application-specific suitability. Documentation that the material is approved for the actual application use conditions.

Manufacturing facility certification. Where applicable, manufacturing facility food-safe certifications.

Annual documentation refresh. FDA approvals update; verify current status periodically.

Additional Regulatory Considerations

Beyond FDA food contact, related regulations:

California Proposition 65 — chemicals of concern requiring labeling. Applies regardless of FDA approval.

State PFAS bans — California AB 1200 and similar restrictions. Apply regardless of federal FDA approval.

Other state-level food contact regulations — varies by state.

International regulations — for operations with international supply chains or distribution.

For comprehensive compliance, FDA food contact compliance is necessary but not sufficient.

Common Compostable Material Categories and FDA Status

Quick reference for common compostable materials:

PLA (cup, container, cutlery): Generally FDA-approved for food contact.

Bagasse fiber (containers, plates): Generally FDA-approved when manufactured to food-grade specs.

Coated paper (with PLA or wax): Generally approved; verify specific coatings.

Bamboo (utensils, plates): Generally approved when food-grade.

Wood (utensils): Generally approved.

PHA (straws, films): Approved with specific FCNs; verify per-product.

Cellulose film: Generally approved for direct food contact.

Sugarcane fiber: Generally approved.

For each material category, per-SKU verification through supplier documentation is the responsible procurement practice.

What “Done” Looks Like for FDA-Aware Procurement

A B2B operation with mature FDA compliance procurement:

• Per-SKU food-grade certification documentation
• Specific regulatory citation per material
• Application-specific suitability verification
• Manufacturing facility certifications where applicable
• Imported material documentation where relevant
• California Prop 65 and state-specific compliance documentation
• Annual documentation refresh
• New SKU approval process integrating compliance verification

The FDA framework provides the foundation for food-safe packaging procurement. Operations that build mature compliance documentation processes avoid compliance gaps and support credible food-safety positioning. The work is administrative more than strategic, but the documentation matters for regulatory compliance, customer trust, and brand risk management.

The supply chain across compostable food containers, compostable bowls, compostable cups and straws, compostable bags, and compostable cutlery and utensils supports food-grade compostable procurement. Operations building integrated procurement should maintain per-SKU food-grade documentation supporting the regulatory compliance foundation.

For B2B operators evaluating FDA compliance documentation, the framework provides systematic structure. Document per-SKU food-grade certification, match materials to application conditions, maintain annual documentation refresh, and the FDA compliance work supports the broader operational compliance foundation.

Verifying claims at the SKU level: ask suppliers for a current Biodegradable Products Institute (BPI) certificate or an OK Compost mark from TÜV Austria, and check that retail-facing copy meets the FTC Green Guides qualifier requirement on environmental claims.
