What buyers pay abroad: import duty in the US, UK, EU and Australia for 2830 90, and China's below.

China: the same goods (2830 90)

China shares the first 6 digits with India and splits them into 10-digit codes of its own: 3 in force under 2830 90. Exporters see what China charges Indian goods; importers see the rebate and licences their Chinese supplier deals with.

China's tariff for these goods
China code	Goods	Duty on Indian goods	MFN	Import VAT	Export rebate	Licences
2830.90.20.00	Antimony sulphide硫化锑	5%MFN rate (no APTA concession on this line)	5%	13%	0%	3BN

2830.90.90.00	Other sulphides; polysulphides其他硫化物、多硫化物	5%MFN rate (no APTA concession on this line)	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.
