9902.03.18 - 2-Benzoylbenzoic acid (CAS No. 85-52-9) (provided for in subheading 2918.30.30)

This classification, HTS Code 9902.03.18, pertains specifically to 2-Benzoylbenzoic acid (CAS No. 85-52-9). This is a particular organic compound used as an intermediate in the synthesis of various dyes and pharmaceuticals. Its inclusion within Chapter 99 signifies that it is subject to temporary legislation, modifications, or additional import restrictions, and it is provided for under subheading 2918.30.30 of the Harmonized Tariff Schedule, indicating its placement within the broader category of carboxylic acids with ketone or aldehyde functions.

As a specific chemical compound, this category is distinct from the broader, more general categories that constitute its siblings at the root level, such as live animals or various categories of agricultural products. These sibling categories are differentiated by their fundamental nature, purpose, and physical form, whereas 9902.03.18 focuses on a precise chemical entity with a designated CAS number. The emphasis here is on the identity and chemical properties of the imported product.

Since HTS Code 9902.03.18 is a leaf node, it does not have further subcategories. Therefore, classification at this level is definitive based on the precise identification of 2-Benzoylbenzoic acid. The temporary nature of this Chapter 99 heading means that importers must remain vigilant regarding any changes to the specific restrictions or provisions applicable to this chemical, as these can be subject to modification over time based on trade agreements and national policy.
