What buyers pay abroad: import duty in the US, UK, EU and Australia for 2920 29, and China's below.

China: the same goods (2920 29)

China shares the first 6 digits with India and splits them into 10-digit codes of its own: 3 in force under 2920 29. Exporters see what China charges Indian goods; importers see the rebate and licences their Chinese supplier deals with.

2920.29.10.00	Other phosphites其他亚磷酸酯	6.5%MFN rate (no APTA concession on this line)	6.5%	13%	0%	None

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.
