Overview

This HTS classification, 3214.90.10.00, specifically designates glazers' putty, grafting putty, resin cements, caulking compounds, and other mastics that are **based on rubber**. These materials are characterized by their rubber content, providing flexibility, elasticity, and sealing properties, making them suitable for applications where these attributes are paramount. Examples include rubber-based caulks for sealing joints in construction, rubberized mastics for automotive repair, or specialized putties formulated for use with rubber components.

Within the broader category of "Other" mastics and fillers (3214.90), this subcategory is distinguished by its primary constituent material. The sibling category, 3214.90.50.00, covers "Other" mastics and fillers that are not specifically rubber-based. Therefore, the key differentiator lies in identifying the dominant material or formulation of the product. If a mastic or putty is primarily composed of rubber or incorporates a significant rubber component for its functional characteristics, it would fall under this classification.

As a leaf node, this classification does not have further subcategories. Classification decisions within this code will therefore rely on a thorough analysis of the product's composition, specifically confirming the presence and functional significance of rubber, and ensuring it meets the general description of glazers' putty, grafting putty, resin cements, caulking compounds, or other mastics as defined within the scope of Chapter 32.
