Last updated: August 2026 dataWire-reinforced cast or rolled glass sheets — produced by embedding a metal wire mesh within the glass during rolling — are a fire-rated glazing material widely specified in building codes for stairwells, fire doors, and industrial skylights. Japan and Italy are the leading suppliers to the US, with China and Germany also present. All imports fall under a single tariff line, 7003200000, and buyers should be aware that fire-rating certifications (such as those from UL or NFPA-compliant testing) are typically required by building authorities independently of customs classification.

Yes — the wire reinforcement is the defining feature that places these sheets in heading 700320 (7003200000) rather than the nonwired sheet headings 700312 or 700319. The wire must be embedded within the glass body during manufacture; a surface-applied wire grid would not qualify. Importers should retain manufacturer documentation confirming the embedded-wire construction.
While customs classification does not require fire-rating certification, US building codes (IBC, NFPA 80) and state fire codes typically require that wired glass used in fire-rated assemblies carry third-party certification (e.g., UL listing) confirming the product meets the applicable fire-resistance and impact-safety standards. Importers should obtain and pass through the manufacturer's certification documentation to downstream customers.
