3813.00.50.00 - Other

This HTS category, 3813.00.50.00, encompasses "Other" preparations and charges for fire extinguishers and charged fire-extinguishing grenades. This classification applies to goods that do not exclusively consist of inorganic substances, as detailed in the sibling category 3813.00.10.00. Consequently, this residual category is intended for mixtures or compounds that contain organic components or are formulated with a specific application in mind for fire suppression beyond simple inorganic agents.

The scope of this heading is broad, covering a variety of chemical formulations designed for fire extinguishment. Examples might include halogenated hydrocarbon-based extinguishing agents, dry chemical powders containing organic binders or flow agents, or specialized foam concentrates that utilize surfactants and polymers. The key differentiator from the "inorganic substances" category is the presence of organic chemical compounds as integral parts of the extinguishing preparation.

Given that 3813.00.50.00 is a leaf node in the HTS structure, there are no further subdivisions. Therefore, the primary classification consideration for goods falling under this code will be to confirm that they are indeed preparations or charges for fire extinguishers or charged fire-extinguishing grenades, and that they do not solely consist of inorganic substances. When classifying items within this category, it is crucial to examine the complete composition and intended use of the product to ensure accurate tariff assignment.
