U.S. imports of starch manufacturing residues: corn gluten feed, corn gluten meal & similar (HS 230310) totaled $2.8M in April 2026, traded with 9 countries.
Importers of Starch Manufacturing Residues: Corn Gluten Feed, Corn Gluten Meal & Similar paid $114K in duties in April 2026 — an effective duty rate of 11% on $1.0M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataCorn gluten feed and corn gluten meal — the two principal co-products of corn wet milling — are separately enumerated at the 10-digit level (2303100010 and 2303100020 respectively), reflecting their distinct protein concentrations and feed-market positioning: gluten meal is a high-protein ingredient used in poultry and aquaculture diets, while gluten feed is a lower-protein, higher-fiber product suited to ruminant rations. A third line (2303100040) captures starch-manufacturing residues not elsewhere specified, including potato and tapioca starch processing waste. Canada and France lead US import supply, with Germany and Denmark also significant sources reflecting Europe's substantial starch-processing industry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
US Customs and Border Protection does not set a fixed protein percentage as the sole classification criterion, but industry convention and CBP rulings generally treat corn gluten meal as the high-protein fraction (typically 60% crude protein on a dry-matter basis) and corn gluten feed as the lower-protein combined fraction. Importers should include a proximate analysis certificate with each shipment to support the declared 10-digit line.
Yes. Line 2303100040 covers starch-manufacturing residues not elsewhere specified, which can include residues from potato, tapioca, and other non-corn starch operations. The key requirement is that the residue originates from a starch extraction process rather than a milling or fermentation process, which would direct it to a different heading.
