9902.03.20 - Glyoxyl acid (Glyoxylic acid) (CAS No. 298-12-4) (provided for in subheading 2918.30.90)

This HTS category, 9902.03.20, specifically addresses Glyoxyl acid (Glyoxylic acid), identified by CAS No. 298-12-4. While its primary classification falls under Chapter 29 (Organic Chemicals), this specific tariff provision within Chapter 99 signifies a temporary modification or special import consideration. Glyoxyl acid is a dicarboxylic acid that serves as a crucial intermediate in various chemical syntheses, including the production of pharmaceuticals, agrochemicals, and dyes.

As a specific temporary tariff provision under Chapter 99, this classification is distinct from the broader categories of live animals or other goods that may be present at the same level of the HTS database. The "99" chapter designation indicates that this is not a standard classification for the inherent nature of the product itself, but rather a classification governed by special legislative or trade agreement provisions.

Since HTS code 9902.03.20 is a leaf node, it does not possess subcategories. Therefore, the focus for classification professionals lies in understanding the specific terms and conditions associated with this temporary provision, ensuring that imports of Glyoxyl acid comply with any stipulated requirements or duties that deviate from its standard classification under subheading 2918.30.90. Accurate documentation and adherence to the scope of Section XXII are paramount when dealing with such specialized tariff entries.
