This page is the public entry point. It explains the issue, links to the public tools that surface the primary records, and routes repeat work into review.
Use this when the starting point is a product description, material, use, or ruling term and the team needs a defensible HTS candidate.
Use this when the HTS line is known and the next question is how origin, base rate, special rates, and additional duties change the answer.
