Products classified under Tariff item 2812.90
99.99% Pure Sulfur Hexafluoride SF6
Ultra-high purity (4N) sulfur hexafluoride gas, electronically graded for semiconductor manufacturing and particle accelerators. It is a chemically defined halide of sulfur, a non-metal, and meets Chapter 28 Note 1(a). It is not specifically named in the subheading, so it falls under this 'other' tariff item.
2812.90.00Arsenic Oxychloride
Arsenic oxychloride (AsOCl3) is a colorless, fuming liquid used in organic synthesis and glass production. It is a chemically defined halide oxide of a non-metal, meeting the criteria of Chapter 28 Note 1(a). It falls under this tariff item as an 'other' halide oxide of non-metals, not specifically named elsewhere in the subheading.
2812.90.00Bulk Liquid Sulfur Hexafluoride Cargo Tank
Liquefied SF6 transported in ISO tank containers for large industrial consumers. The physical state (liquid) does not affect classification; it remains a chemically defined halide of sulfur, a non-metal, under Chapter 28 Note 1(a). It falls under this 'other' tariff item as it is not specifically named.
2812.90.00Carbonyl Fluoride
Carbonyl fluoride (COF2) is a colorless, highly toxic gas used in fluorocarbon production and as a fluorinating agent. As a halide oxide of carbon, it is explicitly included in Chapter 28 by Note 2(a). It is a chemically defined compound, classifiable under this tariff item as an 'other' halide oxide of non-metals.
2812.90.00High-Pressure Sulfur Hexafluoride Ton Cylinder
1-ton capacity SF6 cylinder for large-scale electrical testing facilities. The container is valued separately; the SF6 content is a chemically defined halide of sulfur, a non-metal, meeting Chapter 28 Note 1(a). It falls under this 'other' tariff item as it is not specifically named.
2812.90.00Industrial Grade Sulfur Hexafluoride for GIS Switchgear
Technical grade SF6 gas for gas-insulated switchgear (GIS) in high-voltage electrical substations. It is a chemically defined halide of sulfur, a non-metal, and meets Chapter 28 Note 1(a). It is not specifically named in the subheading, so it falls under this 'other' tariff item.
