HS Code 3505.10 – Dextrins and other modified starches
HS code 3505.10 is the 6-digit subheading for dextrins and other modified starches. It is used for maltodextrin, cyclodextrin, oxidized starch, pregelatinized starch and acetylated starch.
What HS 3505.10 covers
This HS code covers dextrins and other modified starches, which are starches that have undergone various physical, enzymatic, or chemical treatments to alter and enhance their functional properties. These modifications make them highly versatile, serving as thickeners, binders, stabilizers, emulsifiers, and gelling agents across numerous industries. In the food sector, they are indispensable for sauces, confectionery, and processed foods. Industrially, they are used as sizing agents in textiles, binders in paper manufacturing, and excipients in pharmaceuticals. Major importers include food processing companies, textile mills, paper manufacturers, and pharmaceutical firms globally. Exporters are typically countries with large agricultural starch production and advanced processing capabilities. Key trade considerations involve the specific type of modification, desired viscosity, solubility, and compliance with stringent food safety or industrial standards, as their performance characteristics are critical for end-use applications.

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).
