Fused Quartz Optical Rod
A high-purity rod made from fused quartz or fused silica, unworked except for basic forming, used in optical systems and lasers. It falls under HTS 7002.20.10.00 as an unworked rod of fused quartz or other fused silica, prior to any further processing like cutting or polishing.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If subjected to cutting, grinding, or polishing
Rods that are worked beyond basic seaming or annealing are classified under worked glass rods per chapter note (a).
If imported as parts of optical instruments
Fused quartz rods specifically shaped and finished for use in lasers or lenses may shift to Chapter 90 as parts of optical machinery.
If in the form of mineral wool or fibers
Fused silica in fibrous form falls under worked mineral wools if not meeting glass wool specs in heading 7019 notes.

Import Tips & Compliance
• Verify purity certification to confirm fused quartz composition (SiO2 >99.9%) as per chapter notes including fused silica in 'glass' definition
• Provide mill test reports documenting unworked status to avoid misclassification as worked glass under 7002.32
• Ensure packaging prevents damage, as rods are fragile; declare exact dimensions for accurate valuation
