Last updated: April 2026 dataFlat glass products — including float glass, tempered safety glass, laminated glass, and coated architectural glass — are essential inputs for construction, automotive glazing, and solar panel manufacturing. Section 301 tariffs have affected flat glass imports from China, and certain specialty glass products have also been subject to antidumping investigations, making supplier-origin analysis a routine step for procurement teams. Classification hinges on processing state: unworked float glass, toughened glass, and laminated glass each occupy distinct HTS headings with different duty rates. Thickness tolerances, coating type, and whether the glass is cut to size or supplied in stock sheets are the key specification variables that drive both classification and end-use suitability.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Tempered glass undergoes a thermal or chemical strengthening process that places it in a separate HTS heading from unworked float glass. Because the duty rates and any applicable trade-remedy orders may differ between the two forms, importers should confirm the glass's processing state with the manufacturer and document it in the entry package.
For coated glass, the type of coating (e.g., low-emissivity, reflective, or anti-reflective), whether the coating is applied on one or both surfaces, and the glass's thickness and dimensions all influence classification. Requesting a detailed product data sheet from the foreign supplier before the first shipment helps avoid reclassification at the port of entry.
