The headline tariff rate is the small problem. The bigger one: what's inside your BOM that isn't documented, the supplier contract that doesn't pass through, the customer agreement that doesn't allow re-pricing, and the entries that just liquidated without a refund claim filed.
Section 232 on steel, aluminum, and copper now runs 50% on primary metals and 25% on processed derivatives, assessed on the full value of the article since the April 6, 2026 overhaul, with country-specific layers above the MFN base rate. Section 301 on China stacks separately. After the Supreme Court struck IEEPA tariff authority in February 2026, a 10% Section 122 surcharge took its place through July 24, 2026; it does not stack with Section 232. Proposed Section 301 forced-labor duties of 10 to 12.5% on non-232 goods have been floated as a potential successor if Section 122 lapses, but they remain proposed, with no final action or effective date.
This page does two things. First, the Industrial Tariff Pressure Map shows where tariff stacks are landing across HTS chapters typical of industrial sourcing. Second, the two-minute diagnostic surfaces the four exposure dimensions that most middle-market industrial CFOs do not have full visibility on.
Output is a sector-specific exposure brief with prioritized action paths.
Layered tariff exposure by HTS chapter, illustrative for industrial sourcing. Section 232 (steel, aluminum, and copper at 50% primary / 25% derivative) and Section 301 (China) stack on the MFN base rate; the 10% Section 122 surcharge applies to non-232 goods through July 24, 2026 and does not stack with Section 232. Country of origin determines which layers apply.
The industrial exposure brief is sector-specific, drawing on the diagnostic answers and the pressure map data above. It is delivered as a one-page memo with prioritized action paths and the questions to put in front of the CFO and supply chain lead.
