What buyers pay abroad: import duty in the US, UK, EU and Australia for 3815 12, and China's below.
China: the same goods (3815 12)
China shares the first 6 digits with India and splits them into 10-digit codes of its own: 2 in force under 3815 12. 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 |
|---|---|---|---|---|---|---|
| 3815.12.00.10 | Platinum-supported catalysts载铂催化剂 | 5%China's provisional rate, lower than MFN | 6.5% | 13% | 13% | 3 |
| 3815.12.00.90 | Other supported catalysts with precious metal as the active substance其他以贵金属为活性物的载体催化剂 | 5%China's provisional rate, lower than MFN | 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.
