  • Free: 4 tariff items

What buyers pay abroad: import duty in the US, UK, EU and Australia for 2512 00, and China's below.

China: the same goods (2512 00)

China shares the first 6 digits with India and splits them into 10-digit codes of its own: 2 in force under 2512 00. Exporters see what China charges Indian goods; importers see the rebate and licences their Chinese supplier deals with.

  • India is a member of the Asia-Pacific Trade Agreement (APTA). With an APTA certificate of origin, Indian goods pay China's APTA rate where the line has one; China applies the lower of that and its provisional rate.
  • The export VAT rebate is what China refunds its own exporters. When China cuts it, Chinese export prices tend to rise.
