What buyers pay abroad: import duty in the US, UK, EU and Australia for 2921 59, and China's below.

China: the same goods (2921 59)

China shares the first 6 digits with India and splits them into 10-digit codes of its own: 3 in force and 5 expired under 2921 59. 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.
