- 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.
