3824.99.49.00 - Mixtures that are in whole or in part of hydrocarbons derived in whole or in part from petroleum, shale oil or natural gas

This HTS classification covers a broad range of miscellaneous chemical products that are not specifically enumerated elsewhere in the Harmonized Tariff Schedule. The defining characteristic of these mixtures is their origin, being derived wholly or in part from petroleum, shale oil, or natural gas hydrocarbons. This includes a vast array of chemical preparations and mixtures, provided they are not classifiable under more specific headings within Chapter 38 or other chapters of the HTS.

Within the "Other" subcategories at this level, the distinction is made based on the composition of the mixture. While the parent category broadly defines mixtures of hydrocarbons, this specific subcategory, HTS 3824.99.49.00, encompasses all other such mixtures that do not fall under prior "Other" designations or specific compositional criteria that might be identified at higher levels of granularity. This catch-all provision is crucial for ensuring that all qualifying hydrocarbon-derived mixtures find appropriate classification.

As this node is a leaf node in the HTS structure, there are no further subcategories. Therefore, classification within HTS 3824.99.49.00 relies heavily on the precise wording of the description and the exclusion of goods that fit into more specific classifications. Practical classification will often involve examining the intended use, the specific hydrocarbon components, and any added substances to ensure they do not meet the criteria for other headings, particularly within Section VI or related chapters.
