From January 26 to February 25, 2025, the Ministry of Industry and Information Technology (MIIT) solicited opinions on amendments to two mandatory national tire standards.
Amendment No. 1 to GB 9743-2024 Passenger Car Tyres
- Purpose: In Chapter 4.1 of GB 9743-2024, the following is stated: “Main tire parameters such as tire specifications, load index or class, measuring rim, load capacity, inflation pressure, and allowed rims should comply with GB/T 2978 and relevant industry technical documents.” However, the term “relevant industry technical documents” is vague, leading to confusion for certification and subsequent use of the standard.
- Main Content: For a type of tire, if the standard GB/T 2978 Size Designation, Dimensions, Inflation Pressure, and Load Capacity for Passenger Car Tyres specifies its parameters such as tire size, load index, class, measuring rim, load capacity, inflation pressure, and allowed rims, these parameters should comply with the requirements of GB/T 2978. If GB/T 2978 does not specify these parameters, the producer must explicitly specify them.
- Additional Amendment: The original version of GB 9743-2024 stipulates that “all clauses in this document, except for 4.6 (rolling resistance performance) and 4.7 (wet grip performance), shall apply to newly produced tires starting from the effective date of this document.” Considering that GB 9743-2024 will come into effect on May 1, 2025, leaving insufficient time for companies to update certificates, this amendment revises the clause to: “All clauses in this document, except for 4.6 and 4.7, shall apply to newly produced tires six months after the effective date of this document.” This amendment provides an additional six-month buffer for companies to update their certifications.
Amendment No. 1 to GB 9744-2024 Truck Tyres
- Purpose: In Chapter 4.1 of GB 9744-2024, it states that main tire parameters such as tire specifications, load index or class, measuring rim, load capacity, inflation pressure, and allowed rims should comply with GB/T 2977 or relevant industry technical documents. However, the term “relevant industry technical documents” is vague, leading to confusion for certification and subsequent use of the standard.
- Main Content: For a tire, if GB/T 2977 Size Designation, Dimensions, Inflation Pressure, and Load Capacity for Truck Tyres specifies parameters such as tire size, load index, class, measuring rim, load capacity, inflation pressure, minimum dual tire spacing, and allowed rims, these parameters should comply with the requirements of GB/T 2977. If GB/T 2977 does not specify these parameters, the producer must explicitly specify them.
- Additional Amendment: The original version of GB 9744-2024 stipulates that “all clauses in this document, except for 4.6 (rolling resistance performance) and 4.7 (wet grip performance), shall apply to newly produced tires starting from the effective date of this document.” Considering that GB 9744-2024 will come into effect on May 1, 2025, leaving insufficient time for companies to update certificates, this amendment revises the clause to: “All clauses in this document, except for 4.6 and 4.7, shall apply to newly produced tires six months after the effective date of this document.” This amendment provides an additional six-month buffer for companies to update their certifications.
It is expected that these two amendments will be approved and released soon. As GB 9743 and GB 9744 are mandatory standards for tire products entering the Chinese market (referenced in CCC certification), overseas tire manufacturers should promptly complete the renewal of their CCC certificates in accordance with the new standards (2024 edition) and these amendments.
