2929.10.55.00 - Products described in additional U.S. note 3 to section VI

This HTS classification, 2929.10.55.00, encompasses products that possess a nitrogen functional group specifically identified by additional U.S. note 3 to Section VI. These are generally compounds where a nitrogen atom is bonded to one or more organic radicals, and the overall chemical structure aligns with the specific exclusions or inclusions outlined in that U.S. note, which often relates to isocyanates not otherwise specified.

This category is distinguished from its sibling, 2929.10.80, which covers "Other" isocyanates not falling under the specific definitions or exclusions detailed in the additional U.S. note. Therefore, classification here hinges on whether a particular isocyanate compound meets the criteria of additional U.S. note 3 to Section VI.

As this is a leaf node, there are no further subcategories within 2929.10.55.00. Classification at this level will depend on a thorough chemical analysis of the imported product to ensure it precisely matches the description as defined by the cited additional U.S. note.
