HS chapter 29: Organic chemicals
Section VI — Products of the chemical or allied industries
Organic chemicals include a variety of substances such as hydrocarbons, alcohols, and acids. For instance, if you're importing acyclic hydrocarbons like hexane, you'll need to classify it under the appropriate HS-4 code to ensure compliance with customs regulations.
To determine the correct HS-4 code, start by identifying the specific type of organic chemical you are dealing with. For example, if your product is a cyclic hydrocarbon, you would look at heading 2902. Each HS-4 heading narrows down the category based on chemical structure and functional groups.
Once you've selected an HS-4 code, you can further refine your classification to an HS-6 code by examining the detailed notes and descriptions provided in the tariff schedule. For instance, if your product is a halogenated derivative of a hydrocarbon, you would need to check the specific requirements under heading 2903.
Be sure to review any relevant national digits or specific notes that may apply to your product. This could include additional documentation or requirements for certain chemicals, especially those that are regulated due to their hazardous nature.
