Frequently asked
- What does 2909 cover?
- Ethers, ether-alcohols, ether-phenols, ether-alcohol- phenols, alcohol peroxides, ether peroxides, acetal and hemiacetal peroxides, ketone peroxides (whether or not chemically defined), and their halogenated, sulfonated, nitrated or nitrosated derivatives. 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.
