Frequently asked

What does 2831 cover?
Dithionites and sulfoxylates:. This is a heading-level category with several subordinate codes — open one to see its full duty breakdown.
Where does this data come from?
Codes and MFN base rates come from the full USITC HTS 2026 Rev.11 export. Section 301/232/122 surcharge mappings are approximated pending code-level review. Every rate carries a source_url and effective_from, so you can trace it back to the controlling notice.
