3904.90.10.00 - Elastomeric

This HTS code, 3904.90.10.00, specifically designates "Elastomeric" forms of polymers of vinyl chloride or other halogenated olefins. These are essentially materials derived from vinyl chloride or other halogenated olefins that possess elastic properties, meaning they can be stretched and return to their original shape. This classification is distinct from other "Other" categories within heading 3904.90, such as 3904.90.50.00, by its explicit identification of elastomeric characteristics.

The defining feature for classification under this subheading is the material's inherent ability to exhibit elasticity. This differentiates it from other non-elastomeric forms of vinyl chloride or halogenated olefin polymers that might be classified elsewhere. Examples of goods that would fall under this classification include specific types of vinyl-based rubber compounds or synthetic elastomers designed for applications requiring flexibility and resilience, such as certain types of seals, gaskets, or specialized tubing.

As this node is a leaf node in the HTS structure, there are no further subcategories to introduce. Classification decisions at this level are primarily determined by the elastomeric nature of the product, alongside the core definition of it being a polymer of vinyl chloride or other halogenated olefins in its primary form, as established by its parent headings.
