9902.07.42 - (2S)-5-Oxopyrrolidine-2-carboxylic acid-(1S,2S,3S,4R,5S)-5- [4-chloro-3-(4-ethoxybenzyl)phenyl]-1-(hydroxymethyl)- 6,8-dioxabicyclo[3.2.1]octane-2,3,4-triol (1:1) (Ertugliflozin L-pyroglutamic acid) (CAS No. 1210344-83-4) (provided for in subheading 2934.99.30)

This HTS category, 9902.07.42, specifically covers the chemical compound (2S)-5-Oxopyrrolidine-2-carboxylic acid-(1S,2S,3S,4R,5S)-5- [4-chloro-3-(4-ethoxybenzyl)phenyl]-1-(hydroxymethyl)- 6,8-dioxabicyclo[3.2.1]octane-2,3,4-triol (1:1), also known as Ertugliflozin L-pyroglutamic acid. This designation is important for tracking specific pharmaceutical intermediates or finished products that are subject to particular temporary legislation, trade agreements, or additional import restrictions. The inclusion of the CAS number (1210344-83-4) ensures precise identification of this highly specific chemical entity.

Unlike the broad range of live animals found in the sibling categories (0101 through 0105), this category deals with a single, complex organic molecule. Its unique chemical structure and intended pharmaceutical application differentiate it from general chemical classifications or broader drug categories. The context within Chapter 99 highlights that its classification is driven by special provisions and potential import limitations, rather than its fundamental chemical composition, which is already referenced as being provided for under subheading 2934.99.30.

As this is a leaf node in the HTS classification, there are no further subcategories. This means that any importation falling under 9902.07.42 will be classified directly at this level, subject to all relevant temporary legislation and restrictions associated with this specific temporary provision. Classification at this level requires a thorough understanding of the product's identity as Ertugliflozin L-pyroglutamic acid and confirmation of its eligibility for this particular HTS code under applicable trade regulations.
