Low-E Coated Float Glass Sheet 4.8mm from Mexico
A 4.8mm thick float glass sheet with a low-emissivity (low-E) coating that reflects infrared light to improve energy efficiency in windows. Classified under HTS 7005.29.18.10 as float glass with a reflecting layer, surface ground or polished, measuring less than 5mm thick and over 0.65m² in area, not otherwise worked. The microscopically thin metallic oxide layer qualifies as a reflecting layer per chapter notes.

Import Tips
• Verify the reflecting layer meets chapter note definition (microscopically thin metal/chemical coating) with lab certification to avoid reclassification
• Measure sheet area precisely (>0.65m²) and thickness (<5mm) as customs uses actual dimensions for subheading
• Include float glass production certificates; common pitfall is misdeclaring as 'worked' if edges trimmed post-annealing
