When a trade-remedy notice is published, the coverage is defined by tariff classification and country of origin, not by product category as a seller would describe it. Two products that a buyer would call the same thing can sit on different HTS lines and land on different sides of a list.
The practical sequence for an importer is always the same: confirm the ten-digit classification you actually enter under, check whether that line appears in the annex to the notice, check the effective date and whether it applies to goods entered or goods exported on or after that date, and then re-run the landed-cost model.
Primary sources: the notice itself in the Federal Register, and the classification in the Harmonized Tariff Schedule at hts.usitc.gov. Guidance messages to the trade are published by CBP at cbp.gov.
