The US adds an excess-capacity tariff on Thai cars, machinery or rubber goods

The test Between 28 Oct 2026 and 31 Oct 2027, the US imposes a duty under its Section 301 excess-capacity case of 11 Mar 2026 that adds at least 10 percentage points on Thai goods in at least one of autos and parts, machinery or rubber products.

Impact is the average of the four parts, rounded, plus one point when Canada is directly hit on two or more channels, up to 10.

Two separate scales from 1 to 10. Strature never multiplies or merges them.

What changed

Dated, newest first

  1. No USTR Federal Register notice in the excess-capacity case after the initiation, to 28 Oct 2026 [12]
  2. Suphajee: main points of the deal settled, legal wording open; signing expected in November; cabinet, hearings and parliament still needed [5]
  3. Anutin: Thailand at the last paragraph of the Agreement on Reciprocal Trade; the US took 24% of Thai exports so far in 2026 [6]
  4. Thailand pays 12.5% under the forced-labour Section 301 action; Malaysia and Indonesia 10%; 19% reciprocal tariff ended after the February 2026 Supreme Court ruling [4]

Why it matters

Since 24 Jul 2026 most Thai goods have paid a 12.5% US duty under a Section 301 forced-labour action. A second Section 301 case, on structural excess capacity, has named Thailand since 11 Mar 2026; it points at autos and parts, machinery and rubber. No decision has been published. Thailand hopes a trade deal it expects to sign in November will cap its tariffs.

Why Likelihood 4 Pushes: sectors named, no cap on rate or duration, the sister forced-labour cases led to duties in about four months, a widening US deficit with Thailand. Brakes: a deal near signature, Malaysia and Indonesia pay a lower forced-labour rate, no decision seven months on, a negotiated outcome allowed.

Why Impact 5 Key price: landed duty-paid cost of covered Thai goods. Threshold case: 10 added points on one sector.

The other facts on file (5)
  • USTR opened Section 301 excess-capacity investigations into 16 economies including Thailand on 11 Mar 2026; notice published 17 Mar [1] (17 Mar 2026)
  • The notice puts Thailand's 2025 goods surplus with the US at US$51bn, up from US$35bn in 2024 [1] (17 Mar 2026)
  • For Thailand the notice cites surpluses in autos and parts, machinery and rubber, and capacity use below 60% for two years; hearings 5-8 May; no statutory cap on rate or duration [2] (9 Apr 2026)
  • Thai tyres already pay a 25% Section 232 duty; Chinese share of Thai FDI inflows 14% (2017) to 22% (2025) [3] (29 May 2026)
  • US imports from Thailand US$63.0bn (2024), US$91.3bn (2025), US$92.7bn (Jan-Aug 2026) [7] (Aug 2026)

Three scenarios and their signposts

  1. S1

    Deal first

    Thailand signs its Agreement on Reciprocal Trade in November and the case ends for Thailand without a duty.

  2. S2

    Targeted duty

    USTR closes the case with duties on one or two Thai sectors, such as tyres or auto parts.

  3. S3

    Wide duty

    A broad excess-capacity duty adds to the 12.5% across Thai manufacturing.

The signposts of each scenario
PathSignpost
S1A signed text that names the Section 301 cases
S2A determination notice in the Federal Register
S3USTR proposes an action list with a comment period

No probability is given for the three paths.

The other side

A signed deal could bring Thai tariffs in line with Malaysia's and Indonesia's, which Bangkok has sought. If rivals with larger surpluses pay more, Thai plants could win orders.
