💰 Tariff Exclusions for Small Business (2026): How to Apply and Save on Import Duties

by L. Mendoza

Here's what nobody is telling you about tariff exclusions in 2026: the window to claim relief is closing fast, and most small importers are leaving money on the table because they don't know their product is covered. On November 10, 2026, duty relief on more than 190 product codings lapses unless USTR extends again.

After the Supreme Court invalidated the administration's sweeping IEEPA tariffs in February 2026 and the Section 122 surcharge moved toward its July 24 expiry, the quiet workhorse of the trade war is the Section 301 exclusion. But the era of applying for new exclusions is over: following its four-year review, USTR frames the 178 remaining exclusions as a temporary bridge to non-China sourcing, not an open application process.

For a small business, that means one thing: verify whether your imported product matches an active exclusion, claim it correctly at entry, and keep the documentation file ready — before the deadline passes.

Active Section 301 Exclusions (2026)

What Happens on November 10, 2026

What Is a Section 301 Tariff Exclusion, and Does Your Business Qualify?

A Section 301 exclusion is a USTR determination that a specific product — described in plain English in an annex — is exempt from the Section 301 add-on duty for entries during a defined window. Critically, only the Section 301 layer drops: the normal MFN (Column 1) rate, antidumping and countervailing duties, and Section 232 duties all still apply. The available exclusions are narrow, technical, and require an exact match against a ten-digit HTSUS subheading; a product that satisfies six of seven specifications is not covered.

Why Can't I Just Apply for a New Exclusion Anymore?

USTR has not opened a new exclusion request process since its four-year review. The agency's consistent posture is that exclusions are a transitional bridge to non-China sourcing, not a permanent feature. Each extension cycle since 2024 has been short and framed as temporary. Treating November 10, 2026 as a soft deadline that USTR will inevitably extend is a strategy without basis in the stated policy — the history points the other way.

How Do I Verify Whether My Product Is Actually Covered?

First, identify the ten-digit HTSUS statistical reporting number for your product — the exclusion descriptions are tied to specific ten-digit codes, and a mismatch is dispositive. Second, pull the text of U.S. note 20(vvv) (and 20(www) for solar) to subchapter III of chapter 99; the governing annex is FR Doc 2025-21671. Third, compare your product's technical specifications line by line against the description. Fourth, build a contemporaneous documentation file that ties your specs to the exclusion text, the notice, and supporting product literature — this is what protects you if CBP issues a CF-28 or CF-29.

How Do I Claim an Existing Exclusion at Entry?

Report 9903.88.69 as the Chapter 99 secondary on the entry summary and drop the underlying List code (9903.88.01 through .04 or .15). Confirm the entry date falls in the window (November 30, 2025 through 11:59 p.m. ET November 9, 2026), that origin is China (ISO CN), and that the product matches the annex. Reporting both 9903.88.69 and the underlying code on the same line is a frequent error that can trigger a Notice of Action months later.

Can I Recover Duties on Past Entries?

For entries that have not liquidated, a Post Summary Correction can amend the entry summary to the correct Chapter 99 provision. For liquidated entries within the prior 180 days, a protest under 19 U.S.C. § 1514 is the mechanism; it must identify the exclusion claimed, the basis for eligibility, and the supporting documentation. A denied protest can be challenged at the Court of International Trade.

Expert Analysis: The Strategic Bottom Line

For small businesses, the exclusion is not an application to rush — it's a compliance checklist with a hard deadline. If your product qualifies, you should already be transitioning sourcing, because the November 9, 2026 cutoff is real and the underlying rates (7.5% to 25%) are steep. Re-verify the current annex text on the date of entry, because USTR has narrowed descriptions between cycles. The businesses that win here are the ones that locked in documentation before the window closed.
