2833.29.30.00 - Of vanadium

This HTS classification, 2833.29.30.00, specifically covers sulfates that are compounds of vanadium. These are inorganic chemical substances where the sulfate radical (SO₄²⁻) is combined with vanadium in its various oxidation states. Examples include vanadium sulfate, vanadium pentoxide sulfate, or other salts of sulfuric acid with vanadium. The key defining characteristic for classification under this heading is the presence of vanadium as the metallic component.

This category is distinguished from its sibling categories by the specific metal involved. While other sulfates of various metals are classified under 2833.29 (e.g., cobalt, iron, chromium, zinc), this subcategory exclusively pertains to those containing vanadium. This precise distinction is crucial for accurate tariff application, as different metals can confer distinct chemical properties and commercial uses, leading to varying duty rates.

As a leaf node, this classification does not have further subdivisions. Therefore, the focus for classification purposes is on confirming that the sulfate in question is indeed derived from vanadium. Importers and exporters should ensure that the chemical composition and analytical documentation clearly indicate the presence of vanadium as the primary metallic element in the sulfate compound.
