The antidumping rate charged on most Thai passenger and light truck tires entering the US fell from 17.06% when the order took effect in July 2021 to 2.90% in the final results Commerce published on July 20, 2026, and a preliminary review published on October 9, 2026 points to 1.14% for the 2024-25 period. That is a drop of 14.16 percentage points, or 83%, across three completed reviews.
The decline matters now because the order is under sunset review. On September 30, 2026, Commerce told the US International Trade Commission (ITC) that dumping "likely to prevail" without the order would be 21.09% for Thailand, 27.05% for Korea and 101.84% for Taiwan, the highest rates from the 2021 investigation. The ITC decided on September 4, 2026 to run full reviews rather than expedited ones, so the orders, which covered about 44% of US passenger and light truck tire import value in 2020, stay in force until it votes. No schedule has been set yet.
Thai rates fell in every completed review after the 2021 order
The order on Thai tires (case A-549-842) was published on July 19, 2021 with three rates: 21.09% for LLIT (Thailand), 14.59% for Sumitomo Rubber (Thailand) and 17.06% for all other producers. Commerce then ran annual administrative reviews, each of which recalculates dumping on actual US sales during a past period and resets the cash deposit for future entries.
The first review, covering January 6, 2021 to June 30, 2022, was finalized on January 29, 2024. Sumitomo came in at 6.16%, Sentury Tire (Thailand) at 1.24%, and eight non-examined producers, including Deestone, General Rubber, LLIT, Maxxis, Otani, Prinx Chengshan, Sanpo and Zhongce, received a 4.52% review-specific average. The second review (July 2022 to June 2023), final on May 13, 2025, set Sumitomo at 3.76%, Prinx Chengshan at 5.08% and a 3.89% rate for non-examined companies, a list that included the Bridgestone group's Thai entities.
The third review (July 2023 to June 2024), final on July 20, 2026, brought Sumitomo to 0.00% and set Sentury at 2.90%, with the same 2.90% applied to non-examined firms. In the fourth review, Commerce preliminarily calculated 1.14% for Sumitomo and extended that figure to non-examined companies, while rescinding the review for six producer groups including Bridgestone, Deestone, General Rubber, Maxxis, Otani and Sentury. A rescinded company keeps the deposit rate from its last completed segment, so the 1.14% only reaches importers if it survives to final results.

Commerce still projects 21.09% for Thailand if the order ends
The gap between the current deposit and the sunset figure is the central number for anyone pricing Thai supply. Commerce's expedited sunset result does not use the latest review rates. It reports margins from the original investigation, which were calculated before the order constrained pricing. For Thailand that is 21.09%, which is 18.19 percentage points above the 2.90% now set by the latest final review and about 7.3 times higher.
Two procedural facts sit behind that result. First, Commerce initiated the sunset reviews on June 1, 2026, received an adequate response from the domestic interested party on June 30, 2026, and "did not receive a substantive response from any respondent interested party," which is why it ran an expedited 120-day review. Second, the ITC, which decides whether revocation would likely lead to renewed material injury, chose a full review on September 4, 2026 and published that decision on September 25, 2026. A full review means a staff report, questionnaires to US producers and importers, and a hearing, all before any vote.
The precedent most relevant to buyers is China. Antidumping and countervailing orders on Chinese passenger and light truck tires were first published on August 10, 2015, and in July 2026 they were continued for a second time, effective July 7, 2026, after both Commerce and the ITC made affirmative determinations. That outcome does not decide the Thai, Korean, Taiwanese and Vietnamese case, but it shows that a falling deposit rate has not, on its own, been enough to end a tire order.
Korea moved the other way: Hankook's rate nearly tripled to 13.03%
Korean rates followed Thailand's path for two reviews and then reversed. Hankook started at 27.05% in 2021, fell to 6.30% in the 2021-22 review and 4.64% in 2022-23, then rose to 13.03% in the 2023-24 final results published on July 13, 2026. That is an increase of 8.39 percentage points, or 2.8 times the prior rate. Nexen went from 14.72% to 4.29%, 4.09% and then 8.02%, nearly double its previous level. Kumho, which was not individually examined, receives the weighted average of the two, which moved from 5.40% to 4.37% and then to 10.53%.
The next Korean review, for July 2024 to June 2025, was rescinded on April 29, 2026. With no newer result, the 2023-24 rates of 13.03%, 8.02% and 10.53% remain the deposit rates for Korean entries. Korea is therefore the one subject country where the cost of the order rose in the most recent completed review, and the Korean country-level sunset figure of 27.05% equals Hankook's original rate.
Taiwan and Vietnam split between a 0.00% rate and an 84.75% wall
Taiwan shows how wide the dispersion can be inside one order. Nankang Rubber Tire, which received the highest 2021 rate of 101.84%, obtained a 0.00% rate in the 2023-24 review finalized on November 18, 2025. Cheng Shin Rubber, at 20.04% in the original order, did not appear in that review, and any Taiwanese producer without its own rate still faces the 84.75% all-others rate from the investigation.
Vietnam is covered only by a countervailing duty order, because the ITC found Vietnamese dumped imports negligible in June 2021 and terminated that antidumping investigation. The subsidy rates sit in a narrow band. The all-others rate from the investigation is 6.46%. In the 2024 review, preliminary results published on June 23, 2026 put Kumho Tire (Vietnam) at 5.84% and Kenda Rubber (Vietnam) at 3.01%. In its expedited sunset review, published on October 5, 2026, Commerce found that revocation would likely lead to subsidies of 7.89% for Kumho Vietnam, 6.23% for Sailun (Vietnam) and 6.46% for all others.
The 2021 ITC record gives the scale of trade at stake. In its June 23, 2021 vote, the Commission found injury by a 4-1 margin and reported $4.4 billion of subject imports in 2020 against $5.5 billion from nonsubject sources. Subject countries accounted for about 44% of that $9.9 billion import total, and the press release named Thailand, Korea, Mexico, Indonesia and Vietnam as the leading sources by volume.
What the rate path means for tire makers, importers and OEM buyers
Tire makers with Thai plants. For producers that went through review, the order now costs between 0.00% and 2.90% at the deposit stage, against 14.59% to 21.09% in 2021. The economic exposure is the sunset outcome, not the current rate. Planning on a 2.90% duty while the ITC review is open understates the downside by about 18 percentage points for Thai output if the ITC continues the order and later reviews return to investigation-level margins.
Importers and distributors. Cash deposits are estimates. Final liability is set when a review closes, often two or more years after entry. The Korean record shows that the trend can reverse: Hankook's rate fell to 4.64% for 2022-23 entries and was then finalized at 13.03% for entries made between July 2023 and June 2024. Distributors carrying Korean and Taiwanese brands should treat the latest final rate as a reference point for reserving, not a forecast, and should track which producers are named in each annual review request.
OEM and fleet buyers. Supply from Thailand, Korea, Taiwan and Vietnam now faces the same five-year test that the China orders have passed twice. Supply contracts that index landed cost to the current deposit rate should include a clause for a change in duty status, because a negative ITC determination would remove the order entirely, and an affirmative one keeps rates that can rise in later reviews, as Korea shows.
Investors. The spread inside each country is wide: 0.00% for Sumitomo Thailand and Nankang against 84.75% for Taiwanese all-others and 13.03% for Hankook. Company-specific rates, not country headlines, drive margin outcomes for exporters to the US. The ITC schedule, once published, is the next dated event for this group of orders.
Readers tracking demand rather than trade remedies can set these rates against the volume outlook in our North America passenger car tires market analysis, the SUVs and light trucks tires market study, and the replacement tires market report.
Methodology and sources
All rates are weighted-average dumping margins or net countervailable subsidy rates in percent ad valorem, taken from final or preliminary notices published by the US Department of Commerce in the Federal Register. Percentage-point changes and ratios were recalculated from those figures. Preliminary results are labeled as such. Import values come from the ITC's 2021 determination and are in current US dollars. This analysis does not include post-2020 import volumes, which the ITC staff report for the full review is expected to update, and it does not estimate tariffs other than antidumping and countervailing duties.

Frequently Asked Questions
2.90% is the rate from the latest final review (2023-24) for Sentury and non-examined producers, and Sumitomo Rubber (Thailand) is at 0.00%. A preliminary 1.14% for 2024-25 only applies if confirmed in final results.
The all-others rate fell from 17.06% in July 2021 to 2.90%, a drop of 14.16 percentage points or 83%. Sumitomo's rate fell from 14.59% to 0.00% over the same reviews.
Commerce found that dumping of 21.09% would likely prevail for Thailand, along with 27.05% for Korea and 101.84% for Taiwan. The ITC will decide on injury after a full review, for which no schedule has been set.
In the 2023-24 review Hankook's rate rose to 13.03% from 4.64%, Nexen's to 8.02% from 4.09%, and Kumho's to 10.53%. The 2024-25 Korean review was rescinded, so these rates remain in place.
Only by a countervailing duty order, with an all-others rate of 6.46%; the ITC found Vietnamese dumped imports negligible in 2021. Commerce's October 2026 sunset result projects 7.89% for Kumho Vietnam and 6.23% for Sailun.
The ITC reported $4.4 billion of subject imports in 2020 against $5.5 billion from other sources, so the four countries supplied about 44% of import value.
