Taiwan aluminum sheet: CSAC shows zero shipments in AD review
The U.S. Department of Commerce has issued preliminary results in an antidumping duty administrative review of common alloy aluminum sheet from Taiwan, covering April 1, 2024 through March 31, 2025. C.S. Aluminium Corporation (CSAC), a named respondent, made no shipments during the review period. Commerce is inviting interested-party comments on these findings before issuing final results.

On May 14, 2026, the U.S. Department of Commerce released preliminary results of an antidumping duty administrative review covering common alloy aluminum sheet from Taiwan. The review period ran from April 1, 2024 through March 31, 2025.
Key finding
Commerce preliminarily determined that C.S. Aluminium Corporation (CSAC) made no shipments during the period of review. This is a material fact in any ongoing antidumping case, as zero-shipment respondents typically receive favorable or zero-duty margins because there is no dumped merchandise to assess duties against.
What happens next
Interested parties—including importers, domestic producers, exporters, and industry associations—are now invited to submit written comments on Commerce's preliminary findings. These comments will inform the final results of the administrative review, which must be issued within 120 days of publication of the preliminary results (or longer if extended).
Administrative reviews of antidumping orders are conducted annually and allow:
- Named respondents to demonstrate they did not dump during the new period
- Interested parties to challenge preliminary margins or rebut respondent arguments
- Commerce to adjust duty rates based on new evidence
Aluminum sheet (HS Chapter 76) has been a high-profile trade-defense topic. Antidumping and countervailing duties on aluminum products from multiple countries—including Taiwan—remain in force. A zero-shipment finding does not revoke the underlying order but may result in a separate rate or exclusion for that company if circumstances warrant.
Timeline
Comments are due on or before a date specified in the Federal Register notice (typically 30–50 days from publication). Exporters, importers, and freight forwarders handling Taiwan-origin aluminum sheet should monitor this case, as final results may affect duty assessments on future entries.
What this means for shippers
If you import common alloy aluminum sheet from Taiwan, verify whether your supplier or any company in your supply chain is CSAC or another named respondent in this antidumping case. A zero-shipment finding may reduce or eliminate duties for that entity, lowering your landed cost—but only if final results confirm it. Check the final results notice and adjust your tariff classification, duty estimation, and landed-cost modeling before the order takes effect. Use our tools to verify HS classification (Chapter 76) and stay current on antidumping margins as they finalize.
