Last updated: July 2026 dataDespite its name, buckwheat (Fagopyrum esculentum) is not a true cereal grain but a pseudocereal classified in Chapter 10 alongside conventional grains, a distinction that occasionally causes classification questions for mixed-grain products. Russia has historically been the dominant global buckwheat producer and is the leading US import source, followed by Canada and Lithuania. Buckwheat is used in specialty flours, soba noodles, groats, and gluten-free food formulations, giving it a premium niche positioning relative to commodity grains. FDA admissibility requirements apply to food-use shipments.

For HTS classification purposes, buckwheat is treated as a cereal-like grain under Chapter 10, even though botanically it is a pseudocereal (a broadleaf plant, not a grass). This means it is subject to the same general grain-import framework, including FDA food-safety oversight for food-use shipments, but it does not fall under the rice or wheat TRQ structures.
Buckwheat is inherently gluten-free, but cross-contamination during processing or transport is a recognized risk. Importers sourcing buckwheat for gluten-free food manufacturers should obtain supplier certificates confirming dedicated gluten-free processing lines and, where applicable, third-party gluten-free certification. FDA's gluten-free labeling rule (21 CFR Part 101) sets a threshold of less than 20 ppm gluten for products making that claim.
