Overview

This category, HTS Code 2811.19.61.10, specifically classifies sulfamic acid. Sulfamic acid, also known as amidosulfonic acid, is a versatile inorganic acid characterized by its solid crystalline form and strong acidic properties. Its applications span various industries, including cleaning agents, descaling compounds, and as an intermediate in the production of dyes and other chemicals.

While other inorganic acids exist within this chapter, sulfamic acid is distinct due to its unique chemical structure and properties, differentiating it from substances like phosphoric acid or nitric acid. This specific HTS code ensures that sulfamic acid is accurately categorized for import and export purposes, facilitating customs processes and trade compliance.

As this classification represents a leaf node, there are no further subcategories to introduce. The designation of 2811.19.61.10 signifies the most granular level of detail for sulfamic acid within the HTS database, meaning any product classified here is definitively sulfamic acid. Classification under this code relies on the chemical identity and purity of the substance being declared.
