Find the official line.
Search a US HTS code, an ECCN, or words from the official description. Each result is either the import schedule or the Commerce Control List, with the release and the source it came from.
Not legal advice. Tariffkit is a free research tool. It quotes HTS rate text and ECCN control text as published by the official sources linked here. It does not classify an item, does not apply rulings, and does not calculate duty. Verify the cited release with those sources and with counsel before you rely on it.
Searched the Commerce Control List. This query is an ECCN or EAR99.
