Products classified under Tariff item 2904.33
High-Purity Li-PFOS for Electroplating Baths
High-purity lithium perfluorooctane sulfonate (Li-PFOS) in a form designed for use as a surfactant in electroplating baths. It is the lithium salt of perfluorooctane sulfonic acid, a halogenated, sulphonated derivative of a hydrocarbon, and is therefore classifiable under tariff item 2904.33.00.
2904.33.00Lithium Perfluorooctane Sulfonate Powder
Pure lithium perfluorooctane sulfonate (Li-PFOS) in powdered form, used as a fluorinated surfactant in various industrial applications. As the lithium salt of perfluorooctane sulfonic acid, it is a sulphonated, halogenated derivative of a hydrocarbon, falling squarely under tariff item 2904.33.00.
2904.33.00Lithium Perfluorooctane Sulfonate Stabilized Flake
Stabilized flake form of lithium perfluorooctane sulfonate (Li-PFOS) containing a minimal anti-caking agent added solely for safe transport and preservation. Under Chapter 29 Note 1(f), such additions are permitted without changing the classification, so the product remains classifiable under tariff item 2904.33.00 as the lithium salt of perfluorooctane sulfonic acid.
2904.33.00PFOS Lithium Salt Aqueous Solution 70%
A 70% aqueous solution of lithium perfluorooctane sulfonate (Li-PFOS) intended for use in firefighting foam production. Under Chapter 29 Note 1(d), products of heading 29.04 dissolved in water remain classifiable in the chapter, and thus this solution falls under tariff item 2904.33.00 as the lithium salt of perfluorooctane sulfonic acid.
2904.33.00Research Grade Lithium PFOS (>99%)
Research-grade lithium perfluorooctane sulfonate (Li-PFOS) with a purity exceeding 99%, intended for laboratory research on fluorosurfactants. As a separate chemically defined organic compound, it meets the criteria of Chapter 29 Note 1(a) and is classifiable under tariff item 2904.33.00 as the lithium salt of perfluorooctane sulfonic acid.
2904.33.00Technical Grade Lithium PFOS Crystals
Technical-grade lithium perfluorooctane sulfonate (Li-PFOS) in crystalline form, used as a raw material in surfactant manufacturing. It is the lithium salt of perfluorooctane sulfonic acid, a halogenated, sulphonated derivative of a hydrocarbon, and is classifiable under tariff item 2904.33.00.
