The 10 November Cliff: 178 Section 301 Exclusions Expire With No Extension Announced

While the trade press was covering the United States–China truce extension, a smaller and nearer deadline went largely unremarked: the 178 remaining Section 301 product exclusions expire on 10 November 2026, and as of the latest Federal Register record no extension has been published. For importers of Chinese components and finished devices, that date now matters more than the January truce deadline.

What is actually expiring

Section 301 exclusions are the narrow carve-outs that let a specific product, identified by its eight- or ten-digit HTSUS line, enter the United States without paying the Section 301 overlay. Most of the original exclusions were allowed to lapse years ago; the current tranche is the residue — 178 lines — and it has been running on short extensions tied to the wider truce. Three separate US measures lapse on 9 and 10 November 2026, two months before the broader truce itself is due to end in January. Nothing on the public record extends them.

Two things follow. First, a product that was duty-advantaged this summer can be duty-exposed this winter without any change to the product or to the supplier. Second, the exclusion is claimed at the line level, not the product family, so the answer is specific: either the HTSUS code you enter under has a live exclusion or it does not.

The rate stack underneath

The exclusions sit on top of a duty structure that has itself been rebuilt twice this year, so it is worth restating how the layers combine:

• The most-favoured-nation rate for the line — for many semiconductor devices and diodes, zero.
• The forced-labour Section 301 tariff, 12.5%, effective 24 July 2026.
• Legacy Section 301 duties from Lists 1 through 4A, ranging from 7.5% to 100% depending on the line.
• Section 232 duties where the product is caught by a national-security action.

Stacked, the effective rate on most Chinese goods currently sits around 37.5%. At the line level the numbers are blunter still: for semiconductor devices under HTS 8541.59.00 and diodes under 8541.10.00, Chinese origin carries a duty-free base rate plus a 50% Section 301 overlay — a 50% effective rate, against 0% for the same codes from Mexico, Vietnam, Taiwan or the European Union. A further semiconductor Section 301 action is scheduled to take effect on 23 June 2027, with the rate to be announced at least 30 days beforehand, and it is expected to stack on the existing technology-transfer tariff rather than replace it.

Why the truce does not solve this

In late September 2026 the two governments published reciprocal relief lists under a new bilateral framework, each side recommending roughly USD 30 billion of the other's imports for more favourable treatment. It is easy to read that as a tariff cut. It is not, for three reasons. It is a recommendation, not law, and neither side has published the implementing notice that would make any of it claimable. It covers a narrow slice of trade against a very large base. And the carve-outs are explicit: semiconductors, electric vehicles, batteries, rare earths, aircraft, steel, pharmaceuticals, crude oil and liquefied natural gas are excluded from the US list entirely.

The exclusion logic also runs below the line. A toy entered under HTSUS 9503.00.00 qualifies for relief unless it has Wi-Fi, Bluetooth or Ethernet built in — at which point the classification changes and so does the treatment. If your product has a connected variant, assume the relief does not reach it until you have checked.

What to do before 10 November

• Map every SKU to its HTSUS line and check for a live exclusion. Treat last year's schedule as out of date; the residue tranche has changed more than once.
• Model landed cost at the full rate, not the excluded rate. If the exclusion does lapse, the increase is immediate and unbudgeted unless you have priced it in.
• Ask your supplier for the classification evidence — the bill of materials, the technical write-up and any prior ruling for comparable goods. A manufacturer can usually produce it; a trading intermediary often cannot.
• Watch the connected variants. Wi-Fi, Bluetooth or Ethernet can move a product out of a covered line and out of an exclusion at the same time.
• Do not plan against the press release. The reciprocal lists, the truce extension and the exclusion tranche all live or die in the Federal Register. Until a notice publishes, the calculation does not move.

Our position

We ship EXW from Dongguan, so duty is assessed on the importer of record and varies by destination and by line — we do not quote a landed cost we cannot stand behind. What we can do is give you the material descriptions, technical parameters and classification support you need to keep US entry clean, and mark the country of origin accurately and consistently across every document. If your compliance team needs a technical write-up for a specific part or a finished repeller, ask, and we will prepare it. Our earlier note on the Section 301 continuation ruling covers the other half of this picture, and our PCB and PCBA capability list is here for anyone checking where boards are fabricated.
