Quartz Glass Tubes 150mm for Optical Use
Fused quartz glass tubes, 150mm long, unworked, intended for fabrication into optical components like lenses or fiber drawing. Included as 'glass' per Chapter Note on fused silica/quartz; classified in HTS 7002.39.0010 due to unworked state and length under 200mm, without any reflecting layers or shaping.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made from fused quartz but considered other unworked forms
Alternative for unworked fused quartz rods/tubes if not strictly 'tubes' per detailed definitions.
If further worked into glass envelopes for lamps
Processing into finished lamp parts shifts to 7016 for glassware used in electrical applications.
If processed into puffed mineral wool-like forms
Per 7019 note, non-compliant mineral wools from glass fall in 6806, but only if wool-structured.

Import Tips & Compliance
• Include fused silica content certification; fused quartz is 'glass' under tariff notes but distinguish from synthetic crystals in 7104
• Measure length precisely including any flare—exceeding 200mm reclassifies; bundle in protective packaging to prevent accidental working
