Last updated: April 2026 dataWooden windows and French windows — including casement, double-hung, and fixed-light styles — are a significant input for residential and commercial construction, where wood species, glazing configuration, and energy-performance ratings drive purchasing decisions. Imports of wooden window units and frames from certain major supplier countries have historically been subject to antidumping and countervailing duty investigations, making origin documentation and scope rulings a key compliance concern. Builders and distributors should confirm whether specific product configurations fall within the scope of any active trade remedy orders before contracting.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Certificates of origin, mill certifications identifying wood species, and manufacturer declarations are commonly required to support country-of-origin claims and to demonstrate whether a shipment falls within or outside the scope of any active antidumping or countervailing duty orders. A licensed customs broker can advise on the specific documentation package needed.
Classification generally follows the primary material (wood) and the article type (window or frame), but composite constructions — such as wood frames with aluminum cladding — may shift classification to a different heading. Importers should have composite or hybrid window units reviewed carefully to confirm the correct HTS subheading.
