2807.00.00.00 - Sulfuric acid; oleum 🖩

This HTS category, 2807.00.00.00, specifically covers sulfuric acid and oleum. Sulfuric acid is a highly corrosive mineral acid with the chemical formula H₂SO₄. Oleum, also known as fuming sulfuric acid, is a solution of sulfur trioxide (SO₃) in concentrated sulfuric acid, characterized by its high fuming property. These substances are fundamental industrial chemicals used in a vast array of manufacturing processes, including fertilizer production, metal processing, petroleum refining, and chemical synthesis.

As a leaf node within Chapter 28, this HTS code represents a specific product and does not have further subdivisions. Its distinction from sibling categories lies in its chemical composition and industrial application. While other categories in Section VI might cover organic chemicals, inorganic compounds of precious or rare-earth metals, or radioactive elements, 2807.00.00.00 is exclusively for sulfuric acid and oleum. The parent context of Chapter 28, "Inorganic chemicals," accurately frames this classification as a fundamental inorganic compound.
