Export policy (DGFT ITC(HS) Schedule 2) of its tariff items
- Free: 6 tariff items
What buyers pay abroad: import duty in the US, UK, EU and Australia for 2811 29, and China's below.
China: the same goods (2811 29)
China shares the first 6 digits with India and splits them into 10-digit codes of its own: 2 in force and 1 expired under 2811 29. 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 |
|---|---|---|---|---|---|---|
| 2811.29.00.20 | Dinitrogen tetroxide四氧化二氮 | 5%MFN rate (no APTA concession on this line) | 5% | 13% | 0% | 3AM |
| 2811.29.00.90 | Other non-metallic inorganic oxides其他非金属无机氧化物 | 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.
