The July 24 Cliff: Your Flat 10% Is About to Become Country-Specific. Here's What Each Hub Is Looking At.

The Simple Number Is About to Get Complicated

Right now, almost everything you import pays a flat 10%. One number, every country, easy to model. That's Section 122 — the temporary tariff that replaced the IEEPA rates after the Supreme Court struck them down in February.

That simplicity has an expiration date: approximately July 24, 2026. Section 122 carries a 150-day statutory limit, and the President cannot extend it on his own. When it lapses, the flat 10% goes with it — and what replaces it is not flat, not simple, and not the same for every hub.

If you've been planning against 10% across the board, the planning window is closing. Here's what's actually coming, and what each of your sourcing countries is looking at.

What's Replacing It

On March 11, 2026, USTR opened two Section 301 investigations — one into structural excess manufacturing capacity across 16 economies, one into forced-labor enforcement failures across roughly 60 countries. Section 301 is the legally durable tool the administration is using to do what IEEPA couldn't.

A late-May Federal Register notice gave the first concrete shape to the plan. The proposal: a Section 301 tariff of 10% or 12.5% on products from the 60 countries under the forced-labor investigation, with an Annex A exemption list largely mirroring the current Section 122 exemptions. The timing of the July hearings tracks closely to the Section 122 expiration — designed to provide continuity when the flat rate ends.

But that's the floor, not the ceiling. The excess-capacity investigation is separate, country-specific, and product-specific. Section 301 has no statutory rate cap and no time limit. Legal analysts expect the country-differentiated rates to land in a range similar to the invalidated IEEPA rates — meaning well above 10% for the hubs that previously carried high IEEPA numbers.

The key structural detail: unlike the existing China Section 301 tariff, the new Section 301 action is not expected to stack on top of Section 232. That matters for anyone importing steel, aluminum, copper, or their derivatives, which now sit at 50% under the June 1 Section 232 proclamation.

What Each Hub Is Looking At

This is where the flat 10% stops being useful. Here's the picture by country, based on where each one sits across the two investigations and its prior IEEPA history.

China. Already the most exposed and staying that way. China sits on both investigation lists. It already carries Section 301 tariffs of 25% and up on most goods, stacked on the 10% Section 122 — an effective rate around 35% on typical consumer goods today, and far higher on Section 301 high-rate categories. When the new actions land, China's exposure only widens. If you're still in China for affected SKUs, the tariff math is not going to improve.

Vietnam. The hub with the most to lose from the switch. Vietnam dropped from a 46% IEEPA rate to the flat 10% under Section 122 — the single biggest beneficiary of the current regime. It's on both investigation lists, and it just drew a fresh, separate Section 301 investigation into intellectual property enforcement announced at the end of May. Vietnam has the furthest to fall when country-specific rates return. Plan for Vietnam's number to move up meaningfully, not stay at 10%.

India. On both lists, and carrying its own political friction in the trade relationship. India was at the flat 10% under Section 122. Where its country-specific rate lands is genuinely uncertain, but the direction is up, and India's position across both investigations means it could face exposure from two separate tariff actions. If you moved categories to India expecting a durable cost advantage, that advantage needs re-testing against the post-July structure.

Indonesia. Also on both lists, also at the flat 10% today. Indonesia has been one of the quieter beneficiaries of the China shift, with China trade into Indonesia growing sharply through 2025. Its country-specific rate is another unknown, but the same logic applies: the flat 10% is the floor of what's realistic, not the expected outcome.

The pattern across all four: every hub you source from is on at least one investigation list, and the ones you're most likely to be using — China, Vietnam, India — are on both. There is no hub in your network that's insulated from this.

Why "Just Move Hubs" Isn't the Answer This Time

The instinct, when a tariff lands, is to move. It worked before — China got expensive, so production shifted to Vietnam and India. But the July 24 switch is specifically designed to close that escape route.

The whole point of country-differentiated Section 301 rates across 60 countries is that there's no longer a clean low-tariff hub to run to. When the gap between countries narrows or disappears, the arbitrage that drove the last five years of supply chain relocation stops working. You can't dodge a tariff structure that covers every hub at once.

That changes the calculation. The question stops being "which country has the lowest rate" and becomes "where can I actually produce well, at a rate I can model, with a supply chain I can defend." That's a sourcing-quality question, not a tariff-arbitrage question — and it rewards the importers who built real operations over the ones who chased the lowest number.

What To Do Before the Window Closes

Concrete steps, while you still have runway.

1. List every country you source from and check it against both lists. The 16-country excess-capacity list and the 60-country forced-labor list. Most major manufacturing economies are on at least one. The countries on both — China, Vietnam, India, and others — carry the highest risk because two separate investigations can produce two separate tariff actions. Map your exposure corridor by corridor, highest-volume first.

2. Re-run your landed cost model against realistic post-July rates, not the current 10%. Model your high-volume hubs at the upper end of plausible — the IEEPA-era rates are a reasonable reference for where country-specific numbers could land. If your margins only work at 10%, you need to know that now, not in August.

3. Check your contract terms — especially DDP. If you sell on Delivered Duty Paid terms priced against the current 10%, and the rate lands at 25% or higher, the entire duty increase falls on whoever holds DDP responsibility. Review which of your contracts are exposed and reprice or renegotiate before July, not after.

4. Use the remaining low-rate window deliberately. For hubs currently at the flat 10% that are likely to rise — Vietnam especially — the next several weeks may be the lowest rate you'll see for a long time. If front-loading inventory makes sense for your cash position and your product, the window to do it is now. But front-loading is a short-term patch, not a strategy. Don't let it substitute for the structural work.

5. Verify the hubs you're committing to. If the answer to the tariff shift is to consolidate production into your strongest hubs, make sure those hubs are actually as strong as you think — real factories, verified origin, defensible supply chains. The post-July environment rewards quality of operation, and quality is something you verify on the ground, not assume from a quote.

A Note Going Forward

The specific rates aren't final yet. The July hearings, the investigation findings, and the eventual proclamations will fill in the actual numbers over the coming weeks. What's clear now is the direction and the date: the flat 10% ends around July 24, country-specific rates replace it, and every hub in your network is exposed. We're tracking the details as they land, because for a multi-hub importer the country-by-country specifics will determine where production actually makes sense.

The importers who get ahead of this won't be the ones who found the next low-tariff country. They'll be the ones who knew their real exposure across every hub and built their sourcing around operations they could defend.

What Asia Agent Does

Asia Agent provides on-the-ground factory verification and supply chain documentation across China, Vietnam, India, and Indonesia. We connect importers directly to real factories — no middlemen, no trading companies — and verify the operations and origin behind your production in each hub.

When the tariff structure changes and you need to decide where production actually belongs, we give you the ground truth on each hub: what's real, what's defensible, and what will hold up when the rates and the scrutiny both rise.

Our rule doesn't change by country: No inspection, no load. No customs readiness, no ETD.

Frequently Asked Questions

What is Section 122 and when does it expire? Section 122 of the Trade Act of 1974 is the legal authority behind the flat 10% tariff currently applied to nearly all US imports. It was signed in February 2026 after the Supreme Court struck down the IEEPA tariffs, and it carries a 150-day statutory time limit, expiring approximately July 24, 2026. The President cannot extend it unilaterally — only Congress can extend or replace it, and no extension legislation has passed.

What replaces Section 122 after July 24? The administration is moving to replace Section 122 with Section 301 tariffs. A late-May 2026 Federal Register notice proposed a 10% or 12.5% Section 301 tariff on products from the roughly 60 countries under the forced-labor investigation, with an exemption list. Separately, a Section 301 investigation into excess manufacturing capacity across 16 economies is expected to produce country-specific, product-specific rates. Unlike Section 122, Section 301 has no statutory rate cap and no time limit.

Will tariffs go up after Section 122 expires? For most hubs, the realistic expectation is yes. The flat 10% is widely viewed as the floor of plausible 2026 outcomes, not the ceiling. Country-specific Section 301 rates are expected to land above 10% — potentially in the 20-40%+ range for countries that previously carried high IEEPA rates, such as Vietnam, Thailand, Cambodia, and Bangladesh. The exact rates depend on the investigation findings and have not been finalized.

Which sourcing countries are most affected by the switch to Section 301? Countries appearing on both the 16-country excess-capacity list and the 60-country forced-labor list carry the highest risk, because two separate investigations could each produce a tariff action. These include China, Vietnam, and India among others. Vietnam is particularly exposed because it benefited most from the switch to the flat 10% (dropping from a 46% IEEPA rate) and faces an additional new Section 301 investigation into intellectual property enforcement announced in late May 2026.

Does the new Section 301 tariff stack on top of Section 232? According to the late-May Federal Register notice, the new Section 301 tariff is not expected to stack on top of Section 232 tariffs — unlike the existing China-specific Section 301 tariff, which does stack. This matters for goods subject to Section 232, including steel, aluminum, copper, and their derivatives, which were raised to 50% under a June 1, 2026 proclamation. Confirm the final stacking rules once the action is formalized.

Why won't moving to a different country solve the tariff problem this time? The Section 301 actions cover roughly 60 countries simultaneously, which is specifically designed to close the gap that allowed importers to relocate from high-tariff to low-tariff hubs. When country-specific rates apply across nearly all major manufacturing economies, the arbitrage between hubs narrows or disappears. The decision shifts from finding the lowest-rate country to identifying where you can produce well at a rate you can model with a supply chain you can defend.

How should DDP contracts be handled before the tariff change? Under Delivered Duty Paid terms, the party responsible for delivery absorbs all duties at destination. If your DDP contracts were priced against the current 10% Section 122 rate and Section 301 lands at 25% or higher, the full duty increase falls on whoever holds DDP responsibility. Review your DDP-exposed contracts now and reprice or renegotiate before the change takes effect, rather than absorbing an unplanned duty increase after July.

What should importers do before July 24? Map your sourcing exposure against both investigation lists, prioritizing high-volume corridors. Re-run your landed cost model against realistic post-July rates rather than the current flat 10%. Review contract terms, especially DDP. Consider front-loading inventory from hubs currently at 10% that are likely to rise, as a short-term measure. And verify the operations and origin in the hubs you intend to keep, since the post-July environment rewards defensible, well-run supply chains over low-tariff arbitrage.
