2811.19.30.00 - Hydrobromic acid

This category, HTS 2811.19.30.00, specifically classifies hydrobromic acid. Hydrobromic acid is an inorganic acid consisting of hydrogen and bromine. It is a colorless, volatile liquid with a pungent odor, commonly used as a reagent in chemical synthesis, particularly for the production of bromides and in organic chemistry reactions such as alkylation and dehydrohalogenation.

This classification is distinguished from its sibling, 2811.19.10.00, which specifically covers arsenic acid. While both are inorganic acids, their elemental composition and chemical properties are distinct, leading to separate tariff classifications based on the specific nonmetal involved.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, classification within this code hinges on the precise identification of the substance as hydrobromic acid. Key classification criteria would involve confirming its chemical composition and ensuring it is not a preparation or mixture that might fall under a different HTS heading.
