Product classification
HS code for Rubber cement: 3506.91
Adhesives, prepared, based on polymers of heading 3901 to 3913 or on rubber.
Classification of rubber cement under HS 3506.91
Rubber cement is classified under HS code 3506.91. This classification is governed by Chapter 35, which includes glues and other prepared adhesives. Heading 3506 specifically covers prepared glues and other prepared adhesives not elsewhere specified or included. Subheading 3506.91 is designated for adhesives based on polymers of headings 3901 to 3913 or on rubber. Rubber cement is a solution of unvulcanized rubber (natural or synthetic) in an organic solvent (like n-heptane or benzene). Because it is a prepared adhesive ready for use, it fits the description of 3506. The classification is determined by the chemical basis of the adhesive (rubber) and its intended use as a bonding agent. This follows GRI 1 and the Explanatory Notes to Chapter 35, which clarify that products put up for sale as glues or adhesives are classified here.

Codes often confused with 3506.91
Common mistake. Rubber cement is often misclassified under 4005.20, which covers solutions and dispersions of unvulcanized rubber. However, if the solution is prepared as an adhesive with added resins or fillers, 3506.91 is the more specific and correct code. Another common error involves retail packaging; if the rubber cement is put up for retail sale in containers not exceeding a net weight of 1 kg, it may be classified under 3506.10 regardless of its chemical composition.
Top exporters and importers of HS 350691 (the code used for rubber cement), 2025
In 2025, the largest exporter of HS 350691 (the code used for rubber cement) in UN Comtrade data was China, with 19% of world exports; the largest importer in UN Comtrade data was China, with 17% of world imports. Vietnam did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 8.6% of its imports here ($44M, CEPII BACI), so it may also belong among the top importers.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. 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).

Questions about rubber cement
What is the HS code for Rubber cement?
The HS code for Rubber cement is 350691 (Adhesives; prepared, based on polymers of heading 3901 to 3913 or on rubber). The HS code for rubber cement is 3506.91, which applies to prepared adhesives based on polymers or rubber.
How do I classify Rubber cement for customs?
Rubber cement is classified under HS code 350691 — Adhesives; prepared, based on polymers of heading 3901 to 3913 or on rubber. This is a 6-digit subheading level code.
Does the packaging size change the HS code?
Yes. If the rubber cement is packaged for retail sale and weighs 1 kg or less, it is classified under HS code 3506.10 as "Products suitable for use as glues or adhesives, put up for retail sale."
Which countries are the top exporters of rubber cement (HS 350691)?
