Global Customs & Tariff Engineering Optimizer

$1.50 USDC per call · Business, finance and compliance · POST /api/v1/optimize-tariff · Id tariff-engineer

Classifies a product under the HTS with GRI reasoning and verifies the code and general (MFN) rate against the live USITC schedule, flags when a specific sibling subheading may outrank the chosen residual one, separates lower-duty options from reclassification risk with dollar exposure, lists lawful physical tariff-engineering changes, and drafts an accurate commercial invoice description. Leads with a decision, the dollars at stake and the next step. Section 301/232/IEEPA add-ons are model estimates and marked unverified. Not legal advice or a binding ruling.

What you get

A few points of duty on a container is thousands of dollars per shipment, and a wrong code is a penalty risk under 19 U.S.C. 1592; a broker classification review typically costs $100-$300 per product. This returns a verified-rate second opinion with the exposure in dollars.
