Where do the tariff rates come from?

A 15-country x 9-category schedule sourced from the US Harmonized Tariff Schedule (HTSUS) and USTR Section 301 actions, current as of the latest revision. Mexico and Canada are treated as duty-free for qualifying USMCA goods. Section 301 exclusions and product-specific rulings are not modelled.

How is landed cost computed?

Landed cost = COGS + freight (weight x country-specific per-kg rate, sea or air) + 0.7% insurance on (COGS + freight) + duty (COGS x tariff rate) + customs broker fee ($175 per shipment, amortized across units per shipment, minimum 50 units). All real arithmetic; no LLM is involved in computing numbers.

How are alternative sourcing countries selected?

For each unprofitable product, the tool iterates the 14 non-current countries in the schedule, computes landed cost via the same arithmetic, and ranks by savings-per-unit. The top 2 candidates per product are surfaced. Lead-time, MOQ, and supplier capacity are not modelled and should be validated with a customs broker before procurement decisions.

What does Section 301 mean?

Section 301 is a US trade enforcement statute under which an additional tariff (typically 25% in the schedule modelled here) is layered on top of the base HTSUS rate for a wide range of goods imported from China. The sensitivity tornado covers scenarios where it scales up or down.
