Durum wheat (Triticum durum) falls under the 1001 11/19 subheadings, while all other wheat and meslin fall under 1001 91/99. Within each group, seed-grade wheat is separated from non-seed wheat. The durum/non-durum distinction matters commercially because durum commands different pricing and end-use specifications, primarily for semolina and pasta production.

Yes. Seed wheat intended for planting is subject to USDA APHIS phytosanitary import requirements, including inspection and potentially a phytosanitary certificate from the exporting country. Non-seed wheat for milling or feed has a different regulatory profile. Importers should confirm the intended use and applicable APHIS requirements before shipment.
