3827.90.10.00 - Chlorinated but not otherwise halogenated

This HTS classification, 3827.90.10.00, specifically designates mixtures that contain chlorinated derivatives of methane, ethane, or propane, which are not otherwise halogenated and are not elsewhere specified or included. This category encompasses products where chlorine is the sole halogen present on the specified hydrocarbon skeletons. It is crucial to distinguish this subcategory from others that might contain multiple halogens or are classified under different headings based on their primary function or specific chemical composition.

The "Chlorinated but not otherwise halogenated" designation means that while the product is a mixture containing chlorinated methane, ethane, or propane derivatives, it does not contain any fluorine, bromine, or iodine in addition to chlorine. This exclusion is a key differentiator. For instance, if a mixture contained both chlorine and fluorine attached to a methane derivative, it would likely fall under a different classification. The absence of other halogens and the fact that these specific chlorinated derivatives are not classified elsewhere ensures their placement here.

As this is a leaf node, there are no further subcategories under 3827.90.10.00. Therefore, the focus for classification within this code is on confirming that the mixture meets the criteria of containing chlorinated methane, ethane, or propane derivatives and that no other halogens are present. The primary forms or other specific types of these mixtures are addressed by sibling categories, making the specific halogen content the defining characteristic for this particular HTS code.
