Low-E Coated Float Glass Sheet 4.8mm
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If wired glass
Wired glass (with wire netting embedded) falls under 7005.10 regardless of thickness or coatings.
If toughened (tempered) or laminated
Safety-tempered or laminated glass shifts to heading 7007 as 'toughened, tempered or laminated' glass.
If cut to specific shapes or edges ground
Post-annealing cutting to shape or edge working moves it to 7008 as 'multiple walled insulating units' or worked sheets.

Import Tips & Compliance
• 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
