U.S. imports of Dextrins and Other Modified Starches (HS 350510) totaled $35.3M in August 2026, imported from 38 countries.
Importers of Dextrins and Other Modified Starches paid $4.3M in duties in August 2026, an average duty rate of 12.18% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataModified starches and dextrins are critical functional ingredients in food processing, papermaking, textile sizing, and adhesive manufacturing, and the US tariff schedule segments them by starch source: potato-derived dextrins (3505100015), corn (maize)-derived modified starches (3505100040), potato-derived modified starches (3505100045), and residual categories for other dextrins and modified starches. Australia leads US imports under this heading, followed by China and Thailand. Because food-grade modified starches are subject to FDA review, importers should ensure that foreign manufacturers are registered and that product specifications align with intended end-use labeling.

The US HTS distinguishes modified starches by botanical origin — corn (maize) and potato each have dedicated lines (3505100040 and 3505100045 respectively), while other sources fall into the NESOI line (3505100092). Misclassifying by source can result in incorrect duty assessment, so importers should obtain a certificate of origin or technical specification confirming the raw starch feedstock.
Demand comes from several converging industries: food manufacturers use modified starches as thickeners and stabilizers; paper and board producers rely on them for surface sizing; and adhesive formulators use dextrins as binders. This multi-sector demand means import volumes can be influenced by conditions in any of these industries simultaneously.
