Low-E Coated Bent Glass for Skylights
Tempered glass sheets from heading 7005, bent to curve and edge-worked with a low-emissivity (low-E) coating that reflects infrared light for energy efficiency. This absorbent/reflecting layer is a thin metal oxide film applied post-annealing, classifying it under 7006.00.4010 as worked glass not framed. Used in architectural skylight installations to reduce heat gain.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If framed or fitted with other materials like aluminum frames
Framed safety glass shifts to heading 7007, regardless of working.
If not edge-worked or bent, just float glass with low-E coating
Coating alone pre-annealing or without further working stays in 7005 per chapter notes.
If lacking absorbent/reflecting layer
Plain worked glass without specified coating falls into the residual 'other' subheading.

Import Tips & Compliance
• Verify the absorbent/reflecting layer meets chapter note definition (microscopic metal/oxide coating) via lab certification to avoid reclassification
• Provide manufacturer specs confirming base glass from 7003-7005 and post-annealing working; declare value excluding framing
