HS Code for Bulk glue

HS code 3506.99 serves as a residual category for prepared glues and other adhesives that are not specifically mentioned elsewhere in the Harmonized System. While heading 3506 covers a broad range of adhesives, sub-heading 3506.99 is used for products that do not fit into the retail-specific category (3506.10) or other specialized chemical categories. This code is typically applied to industrial-grade adhesives shipped in bulk containers such as drums, totes, or large pails. The classification requires the product to be a "prepared" adhesive, meaning it is a mixture of components ready for use or requiring only simple dilution. Even though some descriptions mention a weight limit of 1kg for specific sub-items in the 3506.10 range, 3506.99 generally captures the "other" category for industrial applications. It is important to note that this code excludes products that have the character of separate chemically defined compounds, which would be classified in Chapter 28 or 29. The versatility of this code makes it a common catch-all for modern synthetic adhesives used in construction, automotive assembly, and packaging industries. Importers must ensure the product is truly a prepared adhesive and not a raw resin or plastic in primary form.

Products Included

Common Misclassification

Bulk glue is often misclassified under 3506.10, which is strictly for products put up for retail sale in packages not exceeding 1kg. Another common error is using 3501.90 for casein-based glues or 3503.00 for gelatin-based glues, which have their own specific headings. Additionally, if the product is a mastic or a filler rather than a pure adhesive, it should be classified under 3214.10.
