New Standard: China's First Mandatory Express Packaging Standard GB 43352-2023 Implemented since June 1st
Published: Author: Visits: 126

On January 25, 2024, the State Administration for Market Regulation (National Standards Committee) held a press conference to introduce five national standards for the express delivery industry. Among them, "Limits of Heavy Metals and Specific Substances in Express Packaging" (GB 43352-2023) is the first mandatory national standard for express packaging in China, which has been implemented since June 1, 2024. The State Post Bureau will work together with market supervision departments to strengthen the inspection and enforcement of the production, sale, testing, and use of express packaging materials. Products that do not meet the mandatory standards are not allowed to be produced, sold, or used. Therefore, the implementation of this standard will have a significant impact on enterprises throughout the upstream and downstream express packaging industry chain. It is recommended that relevant enterprises take early measures for management and response.

Scope of Application

This standard applies to express packaging and mail packaging made of paper, plastic, and textile fibers. It does not apply to express packaging that comes into direct contact with food.

Specific Requirements

The standard stipulates the limits for heavy metals and specific substances in express packaging made of paper, plastic, and textile fibers as shown in the table below. For composite material express packaging made of multiple types of materials, the manufacturing enterprise should declare the types of materials in the composite express packaging, and each material must separately meet the relevant requirements listed in the table below.
