Overview

This classification, HTS 9902.01.99, pertains to Sodium 4-vinylbenzenesulfonate (CAS No. 2695-37-6), which is specifically provided for under subheading 2904.10.37. This category falls within Chapter 99 of the Harmonized Tariff Schedule, which covers temporary legislation and modifications proclaimed pursuant to trade agreements and additional import restrictions. Therefore, this specific HTS code is used for the importation of Sodium 4-vinylbenzenesulfonate when it is subject to these temporary or specific trade-related measures.

Unlike the broader sibling categories which cover live animals (e.g., horses, bovine animals, swine, sheep, goats, and poultry), this node is highly specific. It does not deal with live animals or any other general merchandise. Instead, it isolates a particular chemical compound for the purpose of applying specific trade provisions. The presence of the CAS number further ensures precise identification of the substance.

As this is a leaf node, there are no further subcategories. Classification under 9902.01.99 signifies that Sodium 4-vinylbenzenesulfonate is being imported under a specific, temporary trade rule or restriction as outlined in Chapter 99, rather than being classified under its permanent chemical commodity code. This distinction is crucial for customs compliance and the correct application of duties and any associated trade regulations.
