New Tariffs Hit July 24. How a 20-Person Importer Uses AI to Save 5–15%

Two tariff deadlines are stacking up in the next six weeks. Most small importers are not positioned for either one — and the window to act before the July 24 change is closing fast. This report explains what changed, what it means in dollar terms for a typical SMB import line, and exactly what to do Monday morning.

What Just Changed

Two separate actions landed within days of each other in early June, and both affect small-to-mid-size importers in ways most customs brokers have not fully communicated yet.

Section 232 changes, effective June 8, 2026. A White House proclamation expanded the list of products eligible for the temporary 15% maximum Section 232 tariff rate (down from 25%). The biggest addition: residential HVAC systems and components. Agricultural equipment and certain heavy industrial machinery were also added. This matters because HVAC-related HTS codes — including air-conditioning machines, parts, and evaporator coils — are now explicitly in Annex III of the proclamation, capping their total duty at 15% (base rate + Section 232 combined) through December 31, 2027.

The 85% US-origin threshold — the one most SMBs are missing. The same proclamation lowered the “composed entirely of U.S. metal” threshold from 95% to 85% by weight. That matters because products meeting this standard qualify for a further-reduced 10% maximum combined duty. Many manufacturers who could not hit the 95% bar will qualify at 85% — if they have a current Certificate of Origin breakdown from their supplier. Holland & Knight’s analysis confirms this is one of the most actionable changes in the proclamation for downstream importers.

Section 301 forced-labor tariffs on 60 countries, proposed for July 24. On June 2, 2026, USTR proposed new Section 301 tariffs on all 60 economies under its forced-labor investigation — covering 99.4% of all U.S. imports. The proposed rates: 10% for countries including Mexico, Canada, Cambodia, Bangladesh, and Malaysia; 12.5% for Vietnam, India, Thailand, China, and 50 others. These tariffs are designed to replace the expiring Section 122 10% global surcharge before it lapses on July 24, 2026. White & Case’s briefing notes the comment period closes July 6, with a public hearing July 7 — finalization expected before July 24.

What’s exempt. Products already subject to Section 232 tariffs are carved out of the proposed Section 301 action — no stacking. USMCA-compliant goods from Canada and Mexico are also excluded. Everything else is in scope. Dimerco’s tariff tracker and BNP Paribas EcoNews (June 8) both flag this as a near-certainty before July 24.

Why Your Business Cares

If you’re running a 20-person HVAC distribution shop in Phoenix importing condenser coils from Vietnam and Mexico, here’s what this means in plain math.

On a $400,000 annual import line, the difference between a 12.5% and a 10% tariff rate is $10,000 per year. The difference between 12.5% and a correctly reclassified product that qualifies for the Section 232 reduced rate (capped at 15% combined, or 10% if your coils meet the 85% US-metal threshold) could be $20,000–$40,000 per year. That’s before you account for the supplier markup your trading partners will layer on top once the rates go final.

The reclassification angle. Most SMBs are paying tariffs on products that could qualify for a different HTS code, a more favorable Section 232 tier, or the new US-origin pathway — simply because no one has reviewed their filings since the last rule change. Customs brokers file at entry based on what the importer gives them. They do not proactively audit for savings. Sandler, Travis & Rosenberg note that regular classification reviews routinely surface codes where the product was assigned the wrong heading — often because product specs evolved and the HTS code did not.

Case study: A major U.S. importer found $2.7M in tariff savings through a structured classification and compliance audit. Trade compliance firm Star USA published a 2026 case study documenting exactly this: a large importer engaged them for a compliance redesign, and the resulting Tariff Savings Analysis identified over $2.7 million in potential savings across 21 projects — primarily through better process design, classification accuracy, and automation. That’s a Fortune 500 number, but the same mechanics apply at $400K/year: one misclassified product line, corrected, is real money.

AI-assisted HTS tools now make this audit accessible to SMBs. Four tools cover the practical workflow for a small importer:

For a 20-person distributor with fewer than 50 active SKUs, Flexport’s free simulator handles the initial audit. For bulk reclassification work across a larger catalog, Zonos Classify at $500/month pays for itself in a single corrected SKU on a $400K import line.

What To Do Monday

You have six weeks before the July 24 deadline. Here is the exact three-step playbook, in priority order.

1. Pull your top 10 imported SKUs and run them through one AI HTS classifier. Start with the Flexport Tariff Simulator — it’s free, covers the full tariff stack, and requires no signup. Enter each product’s current 10-digit HTS code and origin country. Then paste the product description into Zonos Classify or Avalara’s classification tool to check whether the AI surfaces a different code at a lower rate. If your condenser coils are classified under a broad derivative-product heading when a more specific HVAC parts code in Annex III would qualify them for the 15% cap, you have found your savings. Most SMBs find at least one discrepancy on their first pass. Document the delta in writing before you call your broker.
2. Check the new 85% US-origin rule against your top bill of materials. The threshold drop from 95% to 85% — confirmed in the June 1 White House proclamation — opens a 10% combined-duty cap for products whose steel, aluminum, or copper content is at least 85% US-origin by weight. If you import fabricated HVAC components assembled in Vietnam or Mexico that use any US-sourced metal, you may already qualify. Email your manufacturer this week and ask for a current Certificate of Origin breakdown showing the percentage of US-origin metal content by weight. C.H. Robinson notes that CBP guidance on how to calculate and document this content percentage is still forthcoming — get your supplier data now so you’re ready when CBP publishes the methodology.
3. Get on the phone with your customs broker this week. If you import from any of the 60 countries in the USTR’s Section 301 forced-labor investigation — Vietnam, Mexico, India, China, Thailand, Cambodia, Bangladesh, Malaysia, and 52 others — you need a rate scenario model before July 24. Ask your broker specifically: (1) which of your HTS codes fall into Annex A exemptions and avoid the new duty; (2) whether any of your goods qualify for USMCA treatment that would shield Mexico-origin imports from the Section 301 rate; and (3) what the cash-flow impact looks like if the 12.5% rate hits your August shipments. The Section 122 10% surcharge expires July 24 and the Section 301 replacement is not yet final — per Skadden’s May briefing, the administration is moving fast to have the Section 301 rates in place before that expiration. Six weeks is not much runway.

If you want to compress this audit into a single session rather than a month of back-and-forth, AdValorem runs a Tariff Engineering Sprint that covers HTS audit, origin qualification review, and broker coordination in one structured engagement — including a Same-Day Rush option at $2,550 for importers staring down the July 24 deadline.
