HS Code for Adhesive mastic

Adhesive mastic is classified under HS code 3214.90, which covers mastics and other painters' fillings. This classification is part of Chapter 32, which includes tanning or dyeing extracts, tannins and their derivatives, dyes, pigments, and other coloring matter, as well as putties and mastics. Heading 3214 is specifically for glazier's putty, grafting putty, resin cements, caulking compounds, and other mastics. Subheading 3214.90 is used for mastics that do not fall under the more specific 3214.10 (glazier's putty). These products are typically used for sealing, filling, or bonding surfaces in construction and industrial applications. They are distinguished from prepared glues of heading 3506 by their thicker consistency and their primary use as fillers or sealants rather than just surface-to-surface adhesives. The classification is determined by the chemical composition and the intended application as a filler or non-refractory surfacing preparation.

Products Included

• Tile adhesives (mastic type)
• Wall mastics for construction
• Joint fillers and sealants
• Resin cements for bonding
• Non-refractory surfacing preparations

Common Misclassification

Adhesive mastics are often confused with prepared glues and other prepared adhesives classified under HS code 3506.91. The distinction lies in the application: 3506 is for adhesives intended for retail sale or specific bonding, while 3214 is for mastics used as fillers or for surfacing. Another misclassification occurs with refractory cements under 3816.00, which are designed to withstand high temperatures, unlike the mastics in 3214.90. Glazier's putty is also frequently misclassified here, but it has its own subheading at 3214.10.
