Investigation Nos. 701-TA-647 and 731-TA-1517-1519 are now active: the U.S. International Trade Commission instituted five-year sunset reviews on June 1, 2026, for antidumping and countervailing duty orders covering passenger vehicle and light truck tires from South Korea, Taiwan, Thailand, and Vietnam. The response deadline is July 1, 2026, with adequacy comments due by August 10, 2026.

These reviews examine whether revoking the original trade remedy orders—issued July 19, 2021 and published at 86 FR 38011-38013—would likely result in continuation or recurrence of material injury to the domestic PVLT tire industry. The countervailing duty order (CVD) applies specifically to Vietnam under Investigation No. 701-TA-647, while the antidumping duty orders (AD) cover South Korea, Taiwan, and Thailand under Investigation Nos. 731-TA-1517-1519.

The Commission is conducting these reviews pursuant to 19 U.S.C. 1675(c) and procedural rules codified at 19 CFR part 207, subparts A and F. The outcome will determine whether the existing duty orders remain in effect or are revoked—a decision that directly impacts duty rate calculations for HTS classifications covering PVLT tires imported from these four subject countries.

Product Scope Definition: The subject merchandise is defined as passenger vehicle and light truck tires (PVLT tires). In the original 2021 determinations, the Commission established the Domestic Like Product as coextensive with this scope—meaning any rate or classification system tracking PVLT tire imports must account for these specific investigation numbers.

For compliance engineering teams maintaining automated tariff lookup systems, the active status of these investigations creates a data integrity challenge. Duty rates on PVLT tires from South Korea, Taiwan, Thailand, and Vietnam remain subject to the 2021 AD/CVD orders until the Commission completes its review. Any system returning rate data for these HTS lines must continue reflecting the additional duties—but must also flag that a sunset review is pending.

The Commission will assess whether interested party responses are adequate to conduct full reviews or whether expedited reviews based on facts available are warranted. This procedural determination, expected after the August 10 adequacy comment deadline, will signal the timeline for final decisions on order continuation or revocation.

Key Dates for System Updates:
• Order Date (original): July 19, 2021
• Review Institution Date: June 1, 2026
• Response Deadline: July 1, 2026
• Adequacy Comments Deadline: August 10, 2026

Trade compliance platforms serving importers of tires from these four Asian markets should ensure investigation number metadata—specifically 701-TA-647 for Vietnam CVD and 731-TA-1517-1519 for the three AD orders—is linked to relevant HTS codes.
