Overview
This HTS chapter, "Organic chemicals," encompasses a vast array of carbon-based compounds. Within this section, HTS code 2925 specifically addresses carboxyimide-function and imine-function compounds. These are organic molecules characterized by the presence of either an imide group (-CO-NR-CO-) or an imine group (C=N-). Prominent examples within this category include saccharin, a well-known artificial sweetener, and its various salts.
Unlike sibling categories at the HTS database root, which primarily deal with live animals or other broad product classifications, HTS 2925 is solely focused on specific types of organic chemical compounds. Its distinction lies in the functional groups that define the molecules it covers, setting it apart from other chemical categories that might focus on different classes of organic compounds, such as alcohols, aldehydes, or hydrocarbons.
The subcategories under HTS 2925 further refine this classification by differentiating between imides and their derivatives, along with their salts, and imines and their corresponding derivatives and salts. This division allows for more precise classification based on the specific chemical structure and functional group present, which is crucial for accurate customs duty assessment and trade statistics.
