Duty drawback (All Industry Rates)

All Industry Rates of duty drawback under this heading
Drawback item	Goods	Rate	Cap
2837	Cyanides, cyanide oxides and complex cyanides	1%	—

Drawback items follow the 4-digit heading, not the 8-digit code: claim the one that describes your goods. Rates of notification 77/2023-Customs (N.T.) as amended, in force on 19 Oct 2026.

Export policy (DGFT ITC(HS) Schedule 2) of its tariff items

Free: 3 tariff items

What buyers pay abroad: import duty in the US, UK, EU and Australia for 2837 19, and China's below.

China: the same goods (2837 19)

China shares the first 6 digits with India and splits them into 10-digit codes of its own: 2 in force and 5 expired under 2837 19. 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
2837.19.10.00	Potassium cyanide氰化钾	4%APTA rate, with an APTA certificate of origin	5%	13%	0%	23ABNM
2837.19.90.00	Other cyanides and cyanide oxides其他氰化物及氧氰化物	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.
