What buyers pay abroad: import duty in the US, UK, EU and Australia for 2917 39, and China's below.

China: the same goods (2917 39)

China shares the first 6 digits with India and splits them into 10-digit codes of its own: 3 in force and 3 expired under 2917 39. 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
2917.39.10.00	Isophthalic acid间苯二甲酸	6.5%MFN rate (no APTA concession on this line)	6.5%	13%	13%	None
2917.39.90.10	Phthalide, methyl chlorophthalate, chlorophthalic acid酞菌酯,氯酞酸甲酯,氯酞酸	6.5%MFN rate (no APTA concession on this line)	6.5%	13%	9%	S
2917.39.90.90	Other aromatic polycarboxylic acids其他芳香多元羧酸	6.5%MFN rate (no APTA concession on this line)	6.5%	13%	13%	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.
