Beijing slaps anti-dumping tariffs on Taiwan’s polycarbonates after protracted probe
- From Saturday, imports of the thermoplastic polymer from Taiwan will be charged extra duty of up to 22.4 per cent, commerce ministry in Beijing says
- Move to be in place for five years, ministry statement says, as Beijing appears to lean on trade tools to push cross-strait message

Imports of the thermoplastic polymer from Taiwan will be charged the extra duty for the next five years, the mainland Ministry of Commerce said in a statement issued on Friday.
It was the final ruling of the ministry’s prolonged anti-dumping investigation into polycarbonates from Taiwan, which started in November 2022.
Last December, Beijing also suspended tariff cuts for 12 important petrochemical products from Taiwan amid growing cross-strait tensions, with the commerce ministry accusing Taipei of placing “barriers” on mainland imports.
“The investigation agency finally determined that there was dumping of the investigated products, that the mainland’s polycarbonate industry had been substantially damaged, and that there was a causal relationship between the dumping and the substantial damage,” the ministry statement said.
Products of two manufacturers, Formosa Chemicals & Fibre and Idemitsu Chemicals Taiwan, will draw 9 per cent anti-dumping duty, going up to 12.2 per cent for Chimei Corp and Chilin Technology, and to 22.4 per cent for those of other Taiwanese companies, the ministry ruling said.
