Latest reviewed evidence

USDA FGIS Directive 9180.76 defines raw buckwheat at a 50.0 percent kernel threshold and uses factor-only inspection rather than a U.S. grade table. It defines Ergoty Buckwheat above 0.05 percent ergot and distinguishes Light Smutty from Smutty at more than 5 versus more than 30 equivalent smut balls in a 250-gram dockage-free portion. These are inspection definitions and condition factors, not results for an untested lot, not product specifications for groats or flour, and not current supply or price.

Buckwheat kernels, groats, grits and flour are separate products

USDA describes buckwheat as fruit of the Fagopyrum genus rather than true cereal grain and defines whole groats as raw kernels with the inedible black hull removed. Directive 9180.69 treats a dehulled kernel as having at least 95 percent of the hull removed; more than 5 percent hull attached is an unhulled kernel. Atlas therefore does not merge raw in-hull buckwheat, white unroasted groats, brown roasted groats, grits, flour, planting seed or feed material.

U.S. inspection is factor-only, not a numbered grade

Directive 9180.76 states that raw buckwheat has no U.S. classes, subclasses or numerical grades. Official analysis can report odor, moisture, garlicky condition, dockage, test weight, ergot and smut, with other safety or condition factors available on request. Whole groats are also factor-only, with separate results for moisture, hull removal, admixture, foreign material, purity, stones and insects. A seller-created grade label must not be presented as a USDA grade.

Each factor retains its sample basis and reporting precision

Raw-buckwheat moisture is measured before dockage removal, while test weight is measured after dockage removal. Ergot and smut use a 250-gram dockage-free portion; garlicky condition uses a 1,000-gram portion. Whole-groat stones and insects use at least 1,000 grams, hull status uses 250 grams, and purity uses 125 grams. Atlas keeps the result, method, sample basis, certificate type and test date together so percentages from different bases are not silently compared.

Inspection factors do not establish a delivered buckwheat price

Identity thresholds and factor-analysis procedures cannot establish crop availability, variety premium, cleaning or dehulling yield, roast state, granulation, food-safety release, package value or logistics. A delivered comparison still needs current permitted observations for the exact raw, groat, grit, flour, seed or feed form; actual factor results; crop year; tested lot; quantity; origin; currency; Incoterm; destination; delivery window; freight and information vintage. Atlas withholds a physical estimate when those observations or usage rights are missing.

Questions procurement teams ask

Does USDA assign a U.S. No. 1 grade to buckwheat?

No. USDA FGIS Directive 9180.76 says raw buckwheat has no classes, subclasses or numerical grades. Inspection is reported by individual factors.

Are buckwheat and whole buckwheat groats the same product?

No. Raw buckwheat retains the hull. Whole groats are dehulled kernels; USDA treats at least 95 percent hull removal as dehulled and more than 5 percent hull attached as unhulled.

What makes a USDA-inspected sample Ergoty Buckwheat?

Under Directive 9180.76, more than 0.05 percent ergot in the specified dockage-free portion is classified as Ergoty Buckwheat. That threshold does not prove any untested lot's condition.

Which fields make buckwheat offers comparable?

Species, raw kernel, groat, grit, flour, seed or feed form, roast and hull state, crop year, inspection basis, moisture, dockage, test weight, garlic, ergot, smut, odor, foreign material, purity, stones, insects, package and lot, quantity, origin, currency, Incoterm, destination, delivery window and evidence date.
