What buyers pay abroad: import duty in the US, UK, EU and Australia for 2815 11, and China's below.
China: the same goods (2815 11)
China shares the first 6 digits with India and splits them into 10-digit codes of its own: 1 in force under 2815 11. 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 |
|---|---|---|---|---|---|---|
| 2815.11.00.00 | Solid sodium hydroxide固体氢氧化钠 | 3.3%APTA rate, with an APTA certificate of origin | 5% | 13% | 0% | ABGNMRS |
- 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.
