Review China-origin tariff exposure across Section 301, AD/CVD, exclusions, HTS lines, and source-backed records.
This page is the public entry point. It explains the issue, links to the public tools that surface the primary records, and routes repeat work into review.
Use this when the immediate question is whether a China-origin HTS line carries a base rate, Section 301 layer, exclusion posture, or other duty assumption.
Use this when the product question turns on an exclusion, extension, expiration, or list-specific record rather than a generic China tariff headline.
Use this when the product family may also sit near an AD/CVD case, injury decision, or investigation record that changes the review posture.
China-origin exposure often sits across several layers at once: base duty, Section 301, AD/CVD risk, exclusion status, and new source records. A single public notice can change the next review question for a product line.
Traverse treats China tariff work as a source-backed memo problem. Public pages show the source layer; Paid review keeps repeated HTS, origin, authority, and case questions together.
Start with the HTS line and origin, then watch Section 301 actions, exclusion status, AD/CVD case activity, and Federal Register or agency records that can change the duty stack.
No. A rate lookup is only one layer. Import teams usually need the source record, effective date, authority, product scope, and any exclusion or remedy context beside the rate.
Keep the HTS line, China-origin posture, supplier or product family terms, Section 301 list or exclusion terms, and any case or agency source together when the question repeats.
The USITC found Voltage LLC and Ningbo Voltage Smart Production Co. violated Section 337 by importing photovoltaic trunk bus cable assemblies infringing U.S. Patent Nos. 12,015,375 and 12,015,376. A Limited Exclusion Order has been issued with a 100% bond during Presidential review; the investigation is terminated.
Commerce is correcting its March 11, 2026 final results notice for the antidumping duty administrative review on chlorinated isocyanurates from China (case A-570-898) to include inadvertently omitted days in the June 1, 2023-May 31, 2024 period of review. The correction does not alter the substantive duty findings but ensures the official record accurately reflects the full POR.
Commerce concluded that revoking antidumping duty orders on polyvinyl alcohol (PVA) from China (A-570-879) and Japan (A-588-861) would likely lead to continuation or recurrence of dumping. The orders remain in effect following this expedited fourth sunset review.
