Products classified under HTS 2505.10.10.00
High-Purity Silica Sand for Glass Manufacturing
This ultra-pure silica sand contains 95% or more silica and no more than 0.6% iron oxide, making it ideal for producing high-clarity glass such as bottles and windows. Its low iron content prevents discoloration in the final glass product. Classified under HTS 2505.10.10.00 due to meeting the strict silica purity and iron oxide limits.
Optical Grade Silica Sand
Premium silica sand with over 95% SiO2 and minimal iron oxide (≤0.6%), used in manufacturing optical glass for lenses and prisms. The low impurities ensure exceptional transparency and clarity. Fits HTS 2505.10.10.00 as natural sand meeting the specified composition criteria.
Ultra-Clean Silica Sand for Flat Glass Production
Naturally occurring sand with 95%+ silica and maximal 0.6% iron oxide, primarily for soda-lime flat glass sheets in construction and automotive. Low impurities yield superior glass quality. Classified in HTS 2505.10.10.00 per chemical composition rules.
Low-Iron Silica Sand for Solar Panel Glass
Specialty sand with ≥95% silica and ≤0.6% iron oxide, essential for float glass in photovoltaic solar panels to maximize light transmission. Low iron prevents greenish tint in the glass. Directly classifiable under HTS 2505.10.10.00 for its precise chemical composition.
Premium Silica Sand for Tableware Crystal Glass
High-grade natural sand exceeding 95% silica with iron oxide under 0.6%, used in crystal glass for fine tableware and stemware. Ensures brilliant clarity without coloration. Meets HTS 2505.10.10.00 specifications for ultra-pure silica sands.
Glass Bottle Grade Silica Sand
Pure silica sand meeting 95%+ SiO2 and ≤0.6% iron oxide standards, used specifically for container glass in beverage and food bottles. Prevents defects and color issues. Falls under HTS 2505.10.10.00 as high-purity natural silica sand.
Fiberglass Production Silica Sand
High-silica sand (≥95% SiO2, ≤0.6% Fe2O3) tailored for E-glass fiberglass reinforcement in composites. Low iron ensures dielectric properties. HTS 2505.10.10.00 classification based on natural sand purity specs.
