What buyers pay abroad: import duty in the US, UK, EU and Australia for 3810 10, and China's below.
China: the same goods (3810 10)
China shares the first 6 digits with India and splits them into 10-digit codes of its own: 1 in force under 3810 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 |
|---|---|---|---|---|---|---|
| 3810.10.00.00 | Pickling preparations for metal surfaces; soldering powders and pastes金属表面酸洗剂焊粉或焊膏 | 6%APTA rate, with an APTA certificate of origin | 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.
