For Southeast Asian exporters targeting the US B2B market, FDA compliance is not optional—it's the price of entry. However, many suppliers misunderstand what "FDA compliant" actually means. The FDA does not certify finished products or issue FDA approval letters for food contact materials. Instead, the agency regulates individual substances that come into contact with food, and compliance is determined by the regulatory status of each component [1].
The regulatory framework is built on Title 21 of the Code of Federal Regulations (21 CFR), specifically Parts 174-179 for indirect food additives. These regulations cover adhesives, paper and paperboard components, polymers, production aids, and adjuvants used in food packaging and processing equipment. A refrigerator interior liner, food processing vessel, or storage container must comply with the specific 21 CFR sections applicable to its material composition [4].
There are three primary pathways to FDA compliance for food contact substances: Food Additive Petitions (requiring pre-market approval), Generally Recognized As Safe (GRAS) determinations under 21 CFR 182-186, and Threshold of Regulation (TOR) exemptions under 21 CFR 170.39 for substances with minimal migration. The appropriate pathway depends on the substance's chemical properties and intended use conditions [1].
FDA regulates individual substances that come into contact with food, not finished products. The overall regulatory status of a food contact material is dictated by the regulatory status of each individual substance it contains. [1]
For exporters, this means you cannot simply claim "FDA approved" on your product listing. You must be able to demonstrate that each material component complies with the applicable 21 CFR section, and you must provide a Letter of Guarantee (LOG) or Declaration of Compliance (DoC) to your B2B buyers. This documentation requirement is where many suppliers fall short [5].
