2829.90 - Other:

This category, HTS Code 2829.90, encompasses inorganic salts of halogens, specifically those that are not chlorates, perchlorates, bromates, perbromates, iodates, or periodates. It serves as a residual classification for other halates and perhalates not specifically enumerated within Chapter 28. The scope primarily includes compounds characterized by the presence of oxygen and a halogen atom, forming anions such as hypohalites (e.g., hypochlorites, hypobromites) or other less common oxyhalide salts.

Distinguishing this category from its sibling, "Chlorates:", is crucial for accurate classification. While "Chlorates:" specifically covers chlorates, which are salts of chloric acid (ClO₃⁻), HTS 2829.90.xx excludes these and instead captures other oxyhalide compounds of halogens. For instance, it would not include potassium chlorate (HTS 2829.10) but could potentially cover certain hypochlorite salts used in industrial applications.

The subcategories within 2829.90 are designed to further refine the classification of these residual halates and perhalates. For example, specific bromate salts, like potassium bromate (2829.90.05.00) and sodium bromate (2829.90.25.00), are itemized due to their distinct commercial significance and potential regulatory considerations. The residual "Other:" designation under 2829.90.xx is for any remaining halates or perhalates not otherwise specified, requiring detailed analysis of their chemical composition and intended use to determine the most appropriate classification.
