Residues of starch manufacture and similar residues

CN code 230310 covers residues from starch manufacture and similar residues, including starch washing sediments, potato pulp, corn gluten feed and corn steep liquor. These products arise as by-products from starch extraction processes using maize, wheat, potatoes and rice. They serve as valuable feed materials due to their fibre, plant protein and residual carbohydrate content. Potato pulp typically contains 5 to 8 percent protein and up to 60 percent residual starch in dry matter. Corn gluten meal, by contrast, is a rich protein source exceeding 60 percent protein content. Classification under code 230310 requires that the products constitute actual residues from the starch extraction process rather than specially manufactured feed preparations, which would be classified under heading 2309.

Starch residues under CN code 230310 are subject to feed safety legislation, particularly Regulation (EC) No 767/2009 on feed marketing and labelling and Directive 2002/32/EC on maximum permitted levels of undesirable substances. Imports from third countries undergo official controls under Regulation (EU) 2017/625. Where starch residues derive from genetically modified crops such as GM maize, the product must hold EU authorisation for use in feed under Regulation (EC) No 1829/2003 and be labelled as GMO under Regulation (EC) No 1830/2003 when GM content exceeds the 0.9 percent threshold. Producers and importers of feed materials must be registered or approved in accordance with Regulation (EC) No 183/2005 on feed hygiene.

For customs clearance of starch residues under CN code 230310, commercial documents must include an accurate product description specifying the plant raw material of origin and the technological process from which the residue arose. For products derived from maize or soya imported from countries using GM crops, such as the USA, Argentina or Brazil, a non-GMO certificate or GMO declaration with the EU authorisation number is recommended. A phytosanitary import certificate is not normally required for processed products of this type, unless the control authorities of the Member State order additional inspections. For goods from countries covered by free trade agreements, verification of preferential tariff rates in the TARIC system is advisable. Corn gluten and pulp trade represents significant commercial volumes in the EU, with reference prices established on commodity exchanges.

Starch production residues under CN 2303 10 carry compound duties. Used as animal feed. Phytosanitary controls apply.
