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 category, 3813.00.10.00, specifically encompasses preparations and charges for fire extinguishers that are composed entirely of inorganic substances. This includes materials such as dry chemical powders, powders for foam extinguishing agents, and other inorganic formulations used in fire suppression systems. The defining characteristic for this classification is the absence of any organic components within the preparation.

This category is distinguished from its sibling, 3813.00.50.00, which covers "Other" preparations and charges for fire extinguishers. The sibling category would therefore include those preparations that contain organic substances, such as certain types of foam concentrates or other formulations that are not solely inorganic. The key differentiator lies in the material composition of the extinguishing agent.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification at this level relies entirely on the determination that the fire extinguisher preparation or charge consists wholly of inorganic materials, thereby distinguishing it from other similar, but organically composed, fire suppression products.
