Reads each product's HS code (US code first) and country of origin. The code is matched against the US Section 338 annex lines (goods made in Canada); the origin sets the Section 301 note. Every match shows its source and as-of date. Products with no HS code are counted and filterable; unmatched products show as not found, never cleared. Read-only: it never reads orders or customers. Tables were transcribed from public annexes with AI assistance and may miss a line. Not legal or customs advice.

• Look up any HS code against the listed lines
• Products with no HS code are counted and filterable so you can fill them in
• Plain next steps: reprice, add the duty at checkout, or ask a customs broker
