7 Steps to Manage Tariffs in a Trade War

Why Are Trade War Tariffs a Permanent Risk in 2026?

Trade war tariffs are now structural, broad-based, and volatile. Rates change within weeks, and even a court defeat can be replaced by a new legal authority. The U.S. imposed a 10% baseline “reciprocal” tariff on nearly all imports under Executive Order 14257, effective April 5, 2025, per the Federal Register. Tariff management is a continuous discipline, not a one-time project.

This affects every finance leader who owns landed cost. E-commerce and retail importers, electronics and hardware makers, electric vehicle (EV) and metals-intensive manufacturers, and agriculture exporters all carry exposure. Tariff risk is cross-sector, as the industry section below shows. The International Emergency Economic Powers Act (IEEPA) tariffs were struck down by the Supreme Court in February 2026, yet the administration pivoted to Section 122 of the Trade Act of 1974, capped at a 15% surcharge for up to 150 days, per a Congressional Research Service brief. Section 301 and Section 232 tariffs, run by the U.S. Trade Representative (USTR) and the Commerce Department, still stand.

Step 1: How Do You Map Your Tariff Exposure?

Build a stock-keeping-unit (SKU) exposure map keyed to 10-digit Harmonized Tariff Schedule (HTS) codes. The map must show the total stacked effective rate per product and origin, not one headline number. Most Favored Nation (MFN) duties, Section 301, and Section 232 all layer onto a single product. Model best-case and worst-case scenarios for each SKU.

The HTS is the U.S. 10-digit system built on the 6-digit international Harmonized System (HS). Classification decides the rate, so misclassification is both a cost and a penalty. Ordering rules matter: Proclamation 11002 bars the new semiconductor Section 232 tariff from stacking with IEEPA programs on the same product, per the Federal Register. Pull data from USTR and U.S. International Trade Commission (USITC) HTS search, the Customs and Border Protection (CBP) Automated Commercial Environment (ACE) portal, and your broker.

Step 2: How Do Rules of Origin and Country of Origin Determination Work?

Origin is a legal test, not “where it was assembled.” Non-preferential origin decides which country’s tariffs apply. Preferential origin decides free trade agreement (FTA) eligibility. The mechanical tests are substantial transformation, tariff-shift, and regional value content (RVC). Audit every supplier’s country of origin (CoO) documentation.

Substantial transformation asks whether processing creates a new article with a different name, character, or use. The first-sale rule is a related valuation lever: it lets duty apply to the first sale in a multi-tier deal, lowering dutiable value. CBP enforces transshipment aggressively, and routing Chinese goods through a third country without genuine transformation is illegal origin-washing that carries penalties. Treat compliance as the guardrail around every tactic, as our global trade compliance guide explains.

Step 3: How Can FTAs, Duty Drawback, and Foreign Trade Zones Cut Tariff Costs?

Three lawful recovery and deferral levers exist, and most importers use none of them. Each one is worth qualifying for.

How do you qualify for USMCA preferential tariffs?

Goods qualify for the United States-Mexico-Canada Agreement (USMCA) only by meeting product-specific rules of origin, usually an RVC threshold or a tariff shift. Autos carry extra regional content and labor value rules. USMCA-qualifying goods escape many broad tariffs, which is the payoff. The scheduled 2026 joint review adds uncertainty to North American sourcing.

How do you claim duty drawback refunds?

Duty drawback recovers up to 99% of duties, taxes, and fees on imported goods that are later exported or destroyed, per CBP. The three types are unused merchandise, manufacturing, and rejected merchandise drawback. You must keep records for 5 years. Key caveat: IEEPA reciprocal tariffs were not drawback-eligible, and the January 2026 semiconductor Section 232 duty carries no drawback under Proclamation 11002. Section 301 duties generally are eligible.

How do foreign trade zones defer duties?

Foreign trade zones (FTZs), bonded warehouses, and temporary importation bonds (TIBs) defer duty until goods enter U.S. commerce. Bonded warehouses defer duty up to 5 years. TIBs allow duty-free entry for goods re-exported within a set period. Goods hit by Section 232 or Section 301 usually enter an FTZ in “privileged foreign” status, which locks the rate and limits inverted-tariff savings.

Step 4: What Is Tariff Engineering and Is It Legal?

Tariff engineering means legally modifying a real product so it classifies under a lower-duty HTS heading. It is lawful under Merritt v. Welsh (U.S. Supreme Court, 1891), as long as the changes are genuine. Misdeclaring an unchanged product is customs fraud. The line is real change versus misrepresentation.

Common approaches include component separation, material composition changes, and design changes that cross classification lines. One 2026 nuance changes the calculus: many current tariffs apply by country of origin, not by HTS heading. Engineering origin through genuine substantial transformation now often matters more than engineering classification. Request a binding CBP ruling for certainty, and bring design teams into tariff planning early. Sector rates vary widely, as our guide on whether clothing is subject to trade tariffs shows.

Step 5: How Do You Monitor Tariff Changes and Legal Risk?

In 2026, monitoring is a weekly function tracking rate changes, new actions, and litigation. Outcomes decide whether you file protective refund claims. The Supreme Court struck down the IEEPA tariffs on February 20, 2026, in a 6-3 ruling, per the Court’s opinion. Refund exposure reaches up to $175 billion, per the Penn Wharton Budget Model.

Your checklist tracks HTS changes, Section 301 and Section 232 actions, trade remedy cases, and Federal Register notices. File protective refund claims and preserve entry documentation while eligibility is live. The pivot to Section 122 proves that even a court win can reverse, so keep watching. Run this cross-functionally, and map filing deadlines with the Commenda compliance calendar.

Step 6: How Do You Build a Tariff-Resistant Sourcing Strategy?

Diversify origins across trading blocs so no single tariff action strands your supply. Nearshore where it shortens lead times, position inventory to smooth exposure, and manage suppliers as a portfolio. Broad-based tariffs shrink the payoff of a simple China-plus-one move, because many alternative countries also faced elevated reciprocal rates.

China’s rare earth export controls remain a live retaliation risk for hardware and clean-energy makers. Rerouting goods through a third country without genuine substantial transformation is illegal transshipment, and CBP penalizes origin-washing. Restated plainly: changing the shipping route does not change legal origin. Remember that tariffs are only one barrier, as our guide to non-tariff barriers to trade covers.

Step 7: How Do You Align Tax, Legal, and Compliance Teams on Tariffs?

Every sourcing or restructuring move triggers second-order tax effects, so trade, tax, legal, and finance must decide together. Shifting production creates tax obligations, transfer pricing changes, and new entity needs in fresh jurisdictions. One team acting alone creates unplanned liabilities.

Six capabilities keep the structure sound. First, global tax nexus and permanent establishment (PE) tracking when sourcing shifts create obligations abroad. Second, multi-entity management for new manufacturing or distribution hubs. Third, transfer pricing adjustments when tariffs change intercompany cost flows. Fourth, strategic incorporation decisions. Fifth, consolidated landed-cost reporting across duties, logistics, and tax. Sixth, scenario planning that models trade actions before they land. Contract terms should allocate tariff risk between DDP and DAP Incoterms, and IP needs protection whenever manufacturing relocates.

Which Industries Face the Biggest Tariff Impact in 2026?

Tariffs now hit every importing sector, but current actions concentrate on autos, metals-intensive manufacturing, electronics and semiconductors, copper-dependent industries, EVs, medical supplies, and e-commerce. Agriculture exporters also carry retaliation risk from Chinese counter-tariffs on U.S. farm goods.

Sector-by-sector exposure (current as of July 2026)

Electronics exposure is structural: the U.S. consumes roughly one-quarter of the world’s semiconductors but manufactures only about 10% of the chips it needs, the Federal Register notes as the Section 232 rationale.
