Frequently asked
- What does 3102 cover?
- Mineral or chemical fertilizers, nitrogenous:. 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.
