Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If processed into float sheets
Float glass sheets, wired or not, are heading 7005.
If for safety glass if tempered post-mass
Tempered/toughened sheets are safety glass in 7007.

Import Tips & Compliance
• Document tin-free status to differentiate from float process sheets
• Weight declarations critical for bulk; mismatches lead to penalties
• Avoid absorbent coatings pre-import per Chapter note definitions
