Food Contact Testing

Ensure your products meet consumer expectations and regulatory requirements for food contact materials with CFR Testing Services from SGS PSI.

“CFR” stands for Code of Federal Regulations. It is a series of rules established by the United States government that are published in the Federal Register and driven by the U.S. Food and Drug Administration (FDA).

There are 50 titles within the CFR covering a wide variety of areas, everything from highways and banking to national defense and public health. Each title has parts and sections. To understand how a specific regulation is written it may be helpful to understand that the title is found to the left of the “CFR”, the part is found to the right of “CFR” and the section or subpart is found to the right of the period.

What are 21 CFR 177 Regulations?

Title 21 of the Code of Federal Regulations pertains to Food and Drugs. Part 177 is titled “indirect food additives: polymers”. These regulations cover materials that come in contact with food, and thus are considered an indirect food additive–examples are food storage containers or food packaging materials. Food contact materials used in the United States must comply with 21 CFR 177 regulations.  These call out materials that are acceptable for use by application and material type (Sections 177.1010 – 177.2910).  They also require specific testing (again called out by application and material type).  These are typically tests for identification and extractable content in various solvents.

CFR Food Packaging Testing can be performed at FDA registered and ISO certified SGS PSI
