FDA 21 CFR 175.300 Indirect Food Additives - Adhesives and Coating Compounds - Resin and Polymeric Coatings

The FDA 21 CFR 175.300 standard, developed by the US Food and Drug Administration (FDA), is a standard known as resinous and polymeric coatings and is a general regulation covering most coating formulations that come into direct contact with food. Coating companies must use materials that comply with FDA regulations, such as this standard, and follow good manufacturing practices in the formulation and production of coatings.

According to the said standard, resinous and polymeric coatings can be safely used as a food contact surface of materials intended to be used in the production, packaging, processing, preparation, transportation or storage processes of foods, in accordance with the conditions specified in the standard.

The coating is applied as a continuous film or enamel on a metal substrate, or the coating is designed for repeated use with food. It is applied to any suitable substrate as a continuous film or enamel that acts as a functional barrier to food. The coating is characterized by one or more of the following descriptions:

  • Oxidation cured coatings
  • Coatings that cure by polymerization, condensation or crosslinking without oxidation
  • Coatings prepared from prepolymerized materials

Coatings are formulated from optional ingredients including:

  • Substances generally recognized as safe in food
  • Substances permitted for use in this standard or authorized by prior sanction or approval and used under the special conditions of previous sanction or approval, if any.
  • Any substance used in the manufacture of resinous and polymeric coatings that is subject to a regulation in this standard and conforms to any specification in that regulation.

Food additive regulations for indirect food additives issued by the FDA are regulations that are often difficult to understand and interpret. The FDA 21 CFR 175.300 standard is among the most complex of these regulations. However, it contains important information.

Among the numerous tests, measurements, analyses, and evaluations our organization provides for businesses in various sectors, we also offer testing services for resinous and polymeric coatings, which are indirect food additives and components of adhesives and coatings, under the FDA 21 CFR 175.300 standard, with our trained and expert staff and advanced technological equipment.
