of HTS Classifications Are Wrong

Manual classification by non-specialists leads to systemic duty miscalculation, CBP audits, and costly post-entry corrections.

Tariff Layers on a Single Entry

Section 301, 232, IEEPA, ADD/CVD, and MFN rates stack unpredictably. Getting the math right requires institutional knowledge few importers possess.

in IEEPA Duties Collected

Following the Feb 2026 SCOTUS ruling, importers are owed refunds — but most lack the tools to identify eligible entries or quantify exposure.

Import Margin OS handles the full classification-to-cost workflow — from raw product description to landed cost, with an auditable record at every step.
