Overview

This HTS classification, 9902.08.97, specifically designates prepared paint driers composed of a defined mixture of cobalt hydroxide, cobalt 2-ethylhexanoate, calcium propionate, calcium 2-ethylhexanoate, hydrotreated heavy naphtha, tripropylene glycol, and tripropylene glycol methyl ether. These substances are intended for use as paint driers and are provided for under subheading 3211.00.00, indicating their role in accelerating the drying process of paints and varnishes. The classification falls under Chapter 99, signifying temporary legislation, trade agreement modifications, or additional import restrictions.

Distinguishing this category from its siblings, which broadly encompass agricultural products like live animals and poultry, is straightforward. Unlike the general agricultural commodities found in the early chapters of the HTS, 9902.08.97 deals with a very specific chemical formulation used in industrial applications for the paint industry. The broad scope of Chapter 01, for example, covers live animals, whereas this category is focused on a manufactured chemical additive. The temporary nature of Chapter 99 classifications also sets them apart from the permanent schedules of goods.

As this is a leaf node, there are no subcategories to introduce. The detailed description within 9902.08.97 provides the definitive criteria for classification. Importers must ensure their product precisely matches the listed chemical components and their intended use as a paint drier to qualify for this specific HTS code. Any deviation in the composition or intended application would necessitate re-evaluation and potentially classification under a different HTS code.
