| What is “food related products”? |
| According to Food Safety Law of the People’s Republic of China, “food related products” refers to food packaging materials and containers, food-applicable detergents, food-applicable disinfectants and equipment in contact with food during production.[6] What we call as “food contact materials and articles (FCM)” fall under the category of “food related products” and include food packaging materials, containers and equipment for food production. |
| Under what circumstances shall users submit application of new food contact substances? |
When any of the following situations exist, relevant stakeholders shall file an application for using new food contact substances, and the competent authority would conduct technical review and consult public feedback before official approval or rejection:
