Overview
This HTS category, 7020.00.30.00, specifically covers quartz reactor tubes and holders. These articles are designed for a specialized industrial application: insertion into diffusion and oxidation furnaces used in the production of semiconductor wafers. The material, quartz glass, and their precise function within semiconductor manufacturing are the defining characteristics for this classification.
This classification is distinct from its siblings. For instance, 7020.00.40.00 pertains to glass inners for vacuum flasks, a completely different application and product type. The residual category 7020.00.60.00, "Other," is a catch-all for glass articles not specifically enumerated elsewhere within this heading, whereas 7020.00.30.00 is a highly specific item. The mention of "I. NATURAL OR CULTURED PEARLS AND PRECIOUS OR SEMIPRECIOUS STONES" indicates a higher-level grouping that encompasses items entirely outside the scope of glass articles.
As a leaf node within the HTS, this category does not have further subdivisions. Classification within 7020.00.30.00 relies on the confirmed material composition of quartz glass and the demonstrated purpose of the tubes and holders for semiconductor wafer production equipment. Any deviation from these specific criteria would necessitate re-evaluation under a different HTS provision.
