HS code for Dextrin: 3505.10
Dextrins and other modified starches.
Classification of dextrin under HS 3505.10
Dextrin is classified under HS code 3505.10, which covers dextrins and other modified starches. This heading is situated within Chapter 35, covering albuminoidal substances, modified starches, glues, and enzymes. Dextrins are a group of low-molecular-weight carbohydrates produced by the hydrolysis of starch. They are typically produced by dry heating starch in the presence of an acid catalyst or through enzymatic action. The classification 3505.10 is specific to starches that have been modified to alter their physical properties, such as solubility, viscosity, or adhesive strength. This distinguishes them from pure, unmodified starches found in Chapter 11. The technical transformation from a raw starch to a modified state is the primary factor for classification under this specific code. Dextrins are widely used in industry as water-soluble glues, as thickening agents in food processing, and as binding agents in the pharmaceutical and textile industries. The HS code 3505.10 ensures that these chemically or thermally treated products are distinguished from agricultural starch commodities.

Codes often confused with 3505.10
Common mistake. Dextrin is frequently misclassified under heading 1108, which is reserved for unmodified starches. The transition to 3505.10 occurs as soon as the starch has undergone a modification process like roasting or chemical treatment. Another common error is classifying dextrin-based glues under 3506. While dextrin itself is in 3505.10, if it is prepared as a glue put up for retail sale in small packages (not exceeding 1 kg), it may fall under 3506.10. Furthermore, chemically pure dextran (a different polysaccharide) should not be confused with dextrin and is classified under heading 2940. Finally, if the product is a food preparation containing a high percentage of sugar, it might be scrutinized under Chapter 17, though 3505.10 remains the primary code for the modified starch component.
Top exporters and importers of HS 350510 (the code used for dextrin), 2025
In 2025, the largest exporter of HS 350510 (the code used for dextrin) in UN Comtrade data was Thailand, with 20% of world exports; the largest importer in UN Comtrade data was China, with 9.4% 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 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).
