How many tires will be affected by the 6PPD regulation worldwide?
2025-01-03
6PPD is widely used in tire manufacturing as a rubber antioxidant. When tires rub against the road surface during driving, particles containing 6PPD are released. After these particles react with ozone, they are transformed into 6PPD-quinone, a chemical substance that is extremely toxic to aquatic organisms.
The California Department of Toxic Substances Control (DTSC) passed a strict regulation on July 26, 2023. The regulation stipulates that from October 1, 2023, all tire manufacturers operating in California must begin evaluating and looking for safer materials that can replace 6PPD.
In addition, for tire manufacturers containing 6PPD, the regulations require a series of actions to be taken before March 30, 2024, including submitting a notice of intent to remove 6PPD from the product, a notice of intent to withdraw the product from the California market, a notice of intent to replace 6PPD with other chemicals, and submitting a preliminary analysis report on potential alternatives to 6PPD.
The United States is one of the main destinations for my country's tire exports. The implementation of this regulation will have a significant impact on my country's tire exports. For tire manufacturers, re-evaluating the product formula and looking for chemicals that can replace 6PPD to ensure that the products meet the requirements of the new regulations requires a certain amount of R&D funds and time, and will also have a certain impact on production costs and supply chains.
However, tire manufacturers whose main export destination is California but who are unable to find suitable substitutes in a timely manner may face the risk of not being able to sell their products in California, which in turn affects their market share and profits.
