HS Code 3506.99 – Glues and other adhesives; prepared, n.e.c. in heading no. 3506, not exceeding a net weight of 1kg

HS code 3506.99 is the 6-digit subheading for glues and other adhesives, prepared, n.e.c. in heading no. 3506, not exceeding a net weight of 1kg. It is used for sodium silicate adhesive, animal glue (bulk, non-retail), vegetable gum adhesive (industrial), specialized inorganic adhesive and certain solvent-based glues (not polymer/rubber).

What HS 3506.99 covers

This is a residual HS code for prepared glues and other adhesives not specifically covered elsewhere in heading 3506. This means it excludes adhesives put up for retail sale in small packs (350610) and those primarily based on polymers of headings 3901-3913 or rubber (350691). This category typically captures industrial or bulk adhesives based on other chemistries, such as certain natural resins, silicates, or inorganic compounds, or complex mixtures that do not fit the more specific classifications. These are often specialized adhesives used for niche industrial applications where specific properties are required. Importers are diverse industrial users, from construction to specialized manufacturing. Exporters are typically chemical manufacturers. Key trade considerations include specific chemical composition, application requirements, safety data sheets, and compliance with relevant industrial standards, as these products often serve very particular functions.

Covers
  • Sodium silicate adhesive
  • Animal glue (bulk, non-retail)
  • Vegetable gum adhesive (industrial)
  • Specialized inorganic adhesive
  • Certain solvent-based glues (not polymer/rubber)
  • Dextrin-based glues (bulk, non-retail, if not covered by 350520)
Examples
  • Elmer's (industrial bulk)
  • Franklin International (Titebond industrial, non-wood specific)
  • various generic industrial silicate glues
  • specialized construction mastics

Codes often confused with 3506.99

Common mistake. This is a 'catch-all' for prepared adhesives, making it prone to confusion with 350610 (if retail packaging is missed) or 350691 (if the polymer/rubber base is not clearly identified or is absent). Careful classification based on composition and packaging is essential.

Top exporters and importers of HS code 350699, 2025

In 2025, the largest exporter of HS code 350699 in UN Comtrade data was China, with 24% of world exports; the largest importer in UN Comtrade data was India, with 7.7% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).

What are common misclassifications for HS code 350699?

This is a 'catch-all' for prepared adhesives, making it prone to confusion with 350610 (if retail packaging is missed) or 350691 (if the polymer/rubber base is not clearly identified or is absent). Careful classification based on composition and packaging is essential.

Which countries are the top exporters of goods under HS code 350699?

In 2025, the top exporters of HS code 350699 in UN Comtrade data were China ($515M, 24% of world exports), the Netherlands ($456M) and the United States ($167M). World exports came to about $2.1B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
