Export policy (DGFT ITC(HS) Schedule 2) of its tariff items
- Free: 4 tariff items
What buyers pay abroad: import duty in the US, UK, EU and Australia for 2904 10, and China's below.
China: the same goods (2904 10)
China shares the first 6 digits with India and splits them into 10-digit codes of its own: 1 in force under 2904 10. Exporters see what China charges Indian goods; importers see the rebate and licences their Chinese supplier deals with.
| China code | Goods | Duty on Indian goods | MFN | Import VAT | Export rebate | Licences |
|---|---|---|---|---|---|---|
| 2904.10.00.00 | Derivatives containing only sulpho groups and their salts and ethyl esters仅含磺基的衍生物及其盐和乙酯 | 5.5%MFN rate (no APTA concession on this line) | 5.5% | 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.
