Spain chlorinated isocyanurates: no dumping found in 2023–24 review
The U.S. Department of Commerce has concluded its administrative review of chlorinated isocyanurates (pool chemicals) imported from Spain for the period June 1, 2023–May 31, 2024, finding no evidence of dumping. This means Spanish exporters of these products will not face additional antidumping duties for this review period, though the existing antidumping order remains in place.

On June 4, 2026, the U.S. Department of Commerce published its final determination in the administrative review of chlorinated isocyanurates from Spain. The agency found that:
sales of chlorinated isocyanurates (chlorinated isos) from Spain were not sold in the United States at less than normal value during the period of review (POR), June 1, 2023, through May 31, 2024.
What this means for shippers
Importers sourcing chlorinated isocyanurates from Spain should confirm with their suppliers and customs brokers that no new dumping margins apply to shipments entering the U.S. during this review window and going forward, pending any subsequent administrative review. The underlying antidumping order on Spanish chlorinated isocyanurates remains active; verify your supplier's compliance status and classification under HS chapter 28 (inorganic chemicals) to avoid duties and potential entry rejections. Check current duty rates and any suspended or revoked provisions before your next shipment.
