HS Code for Industrial adhesive

Industrial adhesives are classified under HS code 3506.99, which falls within Chapter 35 of the Harmonized System. This chapter encompasses albuminoidal substances, modified starches, glues, and enzymes. Specifically, heading 3506 covers prepared glues and other prepared adhesives that are not elsewhere specified or included. The classification 3506.99 is a residual category used for products that do not meet the criteria for retail packaging and are not based on specific chemical compositions defined in other subheadings. These adhesives are essential in manufacturing processes, providing structural bonding, sealing, and assembly across various sectors. The classification depends on the product being a "prepared" adhesive, meaning it is a mixture of components designed for a specific bonding function rather than a single chemical compound. If the product is a pure polymer without additives for adhesive use, it might be classified in Chapter 39. However, once formulated with fillers, plasticizers, or solvents to function as a glue, 3506 becomes the primary heading. This code is often used for bulk industrial shipments of epoxy resins, polyurethanes, and cyanoacrylates that are intended for factory use rather than consumer sale. The technical distinction lies in the preparation and the packaging weight, as specified in the heading notes.

Products Included

• Bulk epoxy resin adhesives
• Industrial polyurethane sealants
• Cyanoacrylate glues for manufacturing
• Hot melt adhesives for industrial packaging
• Structural acrylic adhesives
• Anaerobic threadlockers

Common Misclassification

Industrial adhesives are frequently confused with HS code 3506.10, which is reserved for products put up for retail sale as glues or adhesives, not exceeding a net weight of 1 kg. Another common error is classifying them under Chapter 39 (3907-3911) if the product is a primary form polymer, or under 3214 if the product is considered a mastic or painters' filling.

FAQ

What is the HS code for Industrial adhesive?

The primary HS code for industrial-grade prepared adhesives not elsewhere specified is 3506.99.

Does the packaging size affect the HS code for adhesives?

Yes, if the adhesive is packaged for retail sale and weighs less than 1 kg, it must be classified under 3506.10 regardless of its chemical composition.
