Remind
The new national standard requirements for food contact materials are about to be implemented. Relevant enterprises are reminded to pay attention that after the FCM new national standard is officially implemented, products produced according to the old version of the standard before the implementation date (September 6, 2024) can continue to be sold, while products produced after the date must meet the requirements of the new version of the standard before they can be produced and sold.
Jiayu Testing has the dual qualification testing capabilities of CNAS and CMA for plastics, metals, rubber, composite materials, inks, adhesives and other new national standards. We welcome timely inspection to ensure product compliance!
5 key contents of FCM new national standard
01. GB 4806.7-2023 Plastic materials and products for food contact
Scope of application
Resin, resin blends, plastic materials (various plastic particles, chips, masterbatch, sheets), plastic products, uncured thermoplastic elastomer materials and products. It is also applicable to starch based plastic materials and products used in food contact.
Main changes and requirements
Sensory requirements: Consistent with the 2016 version of the old standard.
Total migration: For starch based plastics with a starch content of ≥ 40%, if the total migration exceeds the limit, add a chloroform extraction step. This step can improve the overall migration qualification rate.
Potassium permanganate consumption: Starch based plastics with a starch content of ≥ 40% do not require this measurement.
Heavy metals (calculated as Pb): consistent with the old standard of 2016 version.
Aromatic primary amine migration: Newly added project, the total migration amount must not be detected (detection limit 0.01mg/kg).
The EU refers to this project as "Primary Aromatic Amine Migration (PAA)", and the EU's migration limit is also not detectable. However, the EU requires a detection limit of 0.002mg/kg for individual substances, which is very strict. Nylon kitchenware is almost reported as violating this project every month. It is recommended to focus on investigating the risk of aromatic amines for colored plastics, composite plastics, and nylon kitchenware products.
Discoloration test: Updated detection method, new method uses color cards, more objective and accurate.

02. GB 4806.9-2023 Metallic Materials and Articles for Food Contact
Scope of application
Metal materials and products for food contact, including various metal coatings and alloys.
Main changes and requirements
Terms and definitions: Add new terms and definitions for alloy elements and impurity elements, and modify the definition of metal coatings.
Raw material requirements: newly added requirements for metal surface treatment; New requirements for the composition of metal materials; Delete the regulations on the shape and purpose of stainless steel materials; Increase the requirement for consistency between the composition of the substrate and coating, as well as the identification grade or composition; Add clauses on metal composition detection methods.
Physical and chemical indicators: The migration amount of elements has changed from stainless steel (5 types) and other metals (3 types) to impurity elements (4 types)+alloy elements (9 types), and the detection standard is unified as GB 31604.49.
Other technical requirements: Add relevant standard regulations for coatings, inks, and/or adhesives; The limit requirement for tin in newly added tin plated thin steel plate containers shall comply with the provisions of GB 2762.
Other: New requirements for testing reusable products have been added to the migration experiment; Stainless steel and other materials are specified separately; Delete special usage requirements; Modify the label identification description.
Appendix: Selection of unified food simulants and migration test conditions, based on expected exposure to food categories and usage conditions.
03. GB 4806.11-2023 Rubber materials and products for food contact
Scope of application
Suitable for rubber materials and products in contact with food, including natural rubber, synthetic rubber, or vulcanized thermoplastic elastomers.
Main changes and requirements
Scope of application: Delete silicone rubber materials and products.
Terms and definitions: Delete the term and definition of "natural rubber".
Raw material requirements: Increase requirements for the use of additives.
Physical and chemical indicators: Increase the requirement for total migration of aromatic primary amines, which must not be detected, with a detection limit of 0.01mg/kg. Increase the requirement for the total migration amount of N-nitrosamine and N-nitrosamine products, which cannot be detected. The detection limits are 0.01mg/kg and 0.1mg/kg, respectively.
Other technical requirements: Rubber materials and products used in food contact with materials such as coatings, inks, and/or adhesives should also comply with the corresponding national food safety standards.
