on december 29, 2022, the state administration for market regulation (standardization administration of the people's republic of china) approved and issued gb 28489-2022 limits of harmful substances in musical instruments, which replaced the gb/t 28489-2012. the nature of the standard has been changed from recommended (gb/t) to mandatory (gb), and the new standard will be implemented on january 1, 2024.
this standard is the first mandatory national standard for the musical instrument industry, applicable to musical instruments, musical instrument accessories, and indoor musical instrument packaging. it specifies the requirements for the content of harmful substances in musical instrument products and updates the test methods for some items, setting higher production standards. the implementation of the new standard requires musical instrument manufacturers to strictly control product quality and ensure product safety. this has a positive impact on promoting the healthy development of the musical instrument industry and enhancing the overall quality and market competitiveness of china's musical instrument products.
it is worth noting that the new standard explicitly states: "for products produced or imported before the implementation date of this document, the requirements of this document shall be met starting from the 13th month after the implementation date." this means that products produced or imported before january 1, 2024, have a one-year transition period and must comply with this standard by no later than january 1, 2025.
quick overview of harmful substance limit requirements
in terms of harmful substance control, the new standard divides musical instruments, musical instrument accessories, and indoor musical instrument packaging into two categories:
category a: instruments and accessories that are in direct contact with the player's mouth under normal use conditions;
category b: instruments, accessories, and indoor musical instrument packaging that are not in direct contact with the player's mouth but can be touched by the human body under normal use conditions.
in addition to the newly added and modified limit indicators, the requirements for restricted substances in electronic musical instruments and electronic components within musical instruments, as well as the requirements for natural radioactive nuclides in stone and ceramic material instruments, have not changed significantly.

as people's living standards improve, various types of musical instruments have entered households. these instruments serve not only for music education and entertainment but also become part of home furnishings and interior decoration. currently, over 80% of musical instruments in homes are prepared for children. during their growth and development, children are a high-risk group vulnerable to toxic materials in products and indoor environmental pollution. prolonged exposure to harmful materials or staying in a polluted indoor environment can cause serious harm to children's health!
the implementation of the new mandatory national standard is of great importance for strictly controlling the pollution of harmful substances from musical instruments to the indoor environment, reducing the harm of instrument pollution to human health, enhancing the overall product quality of the musical instrument industry, and protecting consumers' rights to physical health. this revision of the standard also sets a red line for the import of old pianos, promoting the development of the musical instrument industry towards a safe, healthy, and sustainable path right from the source.
