HS code for Bulk glue: 3506.99
Glues and other adhesives, prepared, n.e.c. in heading no. 3506, not exceeding a net weight of 1kg.
Classification of bulk glue under HS 3506.99
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.

Codes often confused with 3506.99
Common mistake. 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.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
