Last updated: April 2026 dataSteel doors, windows, frames, and door thresholds are widely used in commercial construction, industrial facilities, and security applications, with the US tariff schedule distinguishing between stainless steel articles (7308301000) and non-stainless variants further split by product type — windows and frames (7308305015), thresholds (7308305025), and doors (7308305050). Canada and Mexico are the leading suppliers, benefiting from integrated North American building-products supply chains, while China, Italy, and South Korea also contribute meaningfully. Section 232 tariffs apply to these steel articles, and Chinese-origin goods may carry additional Section 301 exposure. Importers should confirm whether articles are classified as complete door or window units versus structural frames, as the distinction affects both the applicable HTS line and any applicable building-code certifications required by US buyers.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Door frames specifically designed to receive a door leaf — including the jamb, head, and sill — are classified under 7308.30 as frames for doors. Generic structural steel frames for buildings that are not specifically door or window frames fall under 7308.90. The intended function and design of the article, not just its shape, determines the correct heading.
Yes. Stainless steel doors, windows, and frames have their own 10-digit line (7308301000), while non-stainless articles are further subdivided by product type. The alloy composition must be confirmed from mill certifications, as stainless and non-stainless lines may carry different duty rates and different Section 232 treatment depending on any applicable exclusions.
