HS-6 · Subheading
281111
Hydrogen fluoride (hydrofluoric acid)
Heading 2811 — Inorganic acids and other inorganic oxygen compounds of non-metals; n.e.c. in heading no. 2806 to 2810
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-6 281111 when importing or exporting hydrogen fluoride, also known as hydrofluoric acid. This highly corrosive substance is commonly found in industrial applications, such as glass etching and metal cleaning.
Hydrogen fluoride is distinct from other inorganic acids like sulfuric acid (HS-6 2807XX) or hydrochloric acid (HS-6 2806XX), which are used in different chemical processes. Understanding these differences is crucial for proper classification.
This HS-6 line specifically covers hydrogen fluoride in its various forms, including anhydrous and aqueous solutions. It’s important to ensure that your product matches the criteria for this subheading to avoid misclassification.
When dealing with hydrogen fluoride, consider its packaging and intended use. For instance, shipments may include bulk containers for industrial use or smaller quantities for laboratory applications.
