- 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.
China's tariff as compiled by HS编码网 from China Customs, the State Council Tariff Commission and the State Taxation Administration. The Chinese is the original.
