FDA US Food Grade Testing
The US Food and Drug Administration, abbreviated as FDA, is affiliated with the US Department of Health, Education, and Welfare and is responsible for the management of drugs, food, biological products, cosmetics, veterinary drugs, medical devices, and diagnostic supplies nationwide.
（1） Introduction to FDA Food Grade Testing
All utensils, materials, etc. that come into direct contact with food and beverages, or with the tongue of the population, must pass FDA standard testing and certification in order to enter the US market.
1. FDA testing and certification of food packaging materials: paper, plastic film, metal plastic aluminum foil
2. FDA testing and certification of glass ceramic products: various types of glass ceramic products such as pots, bowls, plates, spoons, pots, cups, bottles, pots, etc
3. Food grade plastic products FDA testing and certification: Plastic materials that come into contact with food or are directly imported, mainly including nylon, ABS, ACRY, PU, PE, PC, PVC, PP, PR, PET, PO, PS, PSU, POM, PPS, EVA, SAN, SMM, EVA, BS, MEL, COPP, KRAT, ACRY, etc
4. FDA testing and certification of coating products: paraffin copolymers, PVC coatings, powder coatings, inks, etc. applied to food contact surfaces.
5. FDA testing and certification of plumbing hardware products: faucets, water pipes, containers, pump valves, water heaters, etc. that come into contact with drinking water and tap water
6. FDA testing and certification of rubber resin products
7. FDA testing and certification of sealing materials
8. FDA testing and certification of chemical additives: pigments, preservatives, antioxidants, surfactants, etc
