About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS classification covers hydrogen fluoride, also known as hydrofluoric acid. It is a highly corrosive and reactive inorganic acid, characterized by its chemical formula HF. Its primary applications include use as a fluorinating agent, in etching glass and metals, and in the production of refrigerants and various fluoride compounds.

Hydrogen fluoride is distinguished from its sibling category, hydrogen cyanide (2811.12.00.00), by its chemical composition and reactivity. Hydrogen cyanide is a volatile and extremely poisonous inorganic acid containing a cyano group, whereas hydrogen fluoride is a binary acid of hydrogen and fluorine. The "Other inorganic acids" category itself encompasses a range of inorganic acids not otherwise specified, but this specific code isolates the singular compound of hydrogen fluoride.

As this HTS code represents a leaf node, there are no further subcategories under 2811.11.00.00. Therefore, classification decisions at this level are solely determined by the identification of hydrogen fluoride (hydrofluoric acid) itself, based on its chemical properties and common trade descriptions.
