HS Code for Construction adhesive

Construction adhesives are classified under HS code 3506.91 based on their chemical composition and their preparation for use as an adhesive. Heading 3506 encompasses a wide range of prepared glues and adhesives that are not specified more specifically in other headings. Subheading 3506.91 is particularly focused on products where the primary adhesive component is a polymer (falling under headings 39.01 to 39.13) or rubber. These are 'prepared' adhesives, meaning they are formulated with solvents, fillers, or other additives to make them suitable for bonding materials in construction environments. This includes heavy-duty bonding agents used for flooring, wall panels, and structural components. The classification is determined by the active bonding agent; for instance, if the adhesive is based on polyurethane, acrylic, or synthetic rubber, it fits here. It is important to distinguish these from simple resins or unmixed polymers, as the 'prepared' nature of the adhesive—ready for application—is a prerequisite for heading 3506. The product must be intended for use as an adhesive rather than a sealant or filler.

Products Included

• Polymer-based structural adhesives
• Rubber-based construction glues
• Polyurethane adhesives for subflooring
• Acrylic-based wall panel adhesives
• Liquid nails and similar heavy-duty bonding agents

Common Misclassification

This code is often confused with HS code 3214, which covers mastics and fillers like painters' fillings or resin cements. If the product is put up for retail sale in packages not exceeding 1 kg, it must be classified under HS code 3506.10 regardless of its chemical composition.

FAQ

What is the HS code for construction adhesive?

The HS code for prepared construction adhesives based on polymers or rubber is 3506.91.

Does the packaging size affect the HS code?

Yes, if the adhesive is in a container weighing 1 kg or less and labeled for retail sale, it moves to HS code 3506.10.
