AD/CVD is scope-driven
A case can mention HTS codes for customs convenience while legal scope depends on product descriptions and Commerce records.
How to use the signal
Use the flag to start a broker or counsel review before filing, not as a final rate calculation.
FAQ
Why not calculate AD/CVD rates automatically?
Because a false precise answer can be worse than uncertainty. Scope and producer/exporter facts need review.
Use this guide with a saved code
The safest workflow is to pair the concept in this guide with a concrete HTS code, country of origin, supplier facts, and planned entry date. That keeps the discussion anchored in official source text instead of generic tariff commentary.
When a saved-code alert fires, use the guide to decide which question to ask first: whether the HTS code is still appropriate, whether a trade-remedy overlay applies, whether an exclusion or preference program changes treatment, or whether the issue needs broker review before filing.
