Cereal Flours Not Elsewhere Specified

Blended cereal flours that do not contain wheat or meslin may fall under the mixture line (1102903000) rather than a single-grain line. The correct classification depends on whether the product is a defined single-grain flour or a deliberate mixture; importers should document the composition clearly, as CBP may request laboratory analysis to verify the blend ratio and confirm the appropriate 10-digit line.

Rice flour from certain origins may be subject to FDA import alerts related to pesticide residues or heavy-metal contamination, particularly arsenic, which naturally concentrates in rice. Importers sourcing rice flour from Thailand or India should confirm that their foreign supplier has a robust testing program and that shipments are not covered by an active FDA import alert, which can trigger automatic detention.
