Kidney Beans

Kidney beans are not one interchangeable trade item. Dark Red Kidney, Light Red Kidney and White Kidney are separate U.S. classes, while dry beans, splits and canned beans use different grade and processing evidence. Atlas fixes class, species, crop year, dry or processed form, grade, moisture, defects, package, lot, origin and delivery terms before comparing offers.

The USDA bean standards list White Kidney, Light Red Kidney and Dark Red Kidney as separate classes. For these classes, U.S. No. 1 through U.S. No. 3 carry an 18.0 percent maximum moisture threshold, while U.S. No. 1 permits 2.0 percent total defects, 0.5 percent total foreign material and 0.2 percent stones. Codex CXS 171-1989 provides 15 and 19 percent bean-moisture ceilings for different climatic and storage practices. These are official grade and food-standard limits, not results for an untested lot, current supply measures or live physical prices.

Dark red, light red and white kidney beans are separate classes

USDA defines White Kidney, Light Red Kidney and Dark Red Kidney as distinct bean classes and describes their characteristic size, shape and colour. The same standards distinguish Small Red, Pink, Pinto and other beans. Atlas retains the declared class, cultivar where available, species, crop year and origin; a generic red-bean label does not establish a kidney-bean class or make two lots comparable.

Dry whole beans, splits and canned beans stay separate

The USDA dry-bean standards cover dry threshed beans, including whole, broken and split beans used for edible purposes. Separate USDA specifications govern canned dried beans and distinguish dark red from light red kidney beans. Atlas records dry or canned form, whole or split condition, brine or sauce where processed, package format, drained-weight or fill evidence where applicable, and the exact standard or purchase specification used.

Grade limits need lot-specific sampling and inspection

For White, Light Red and Dark Red Kidney classes, the USDA table sets maximum moisture, total defects, damage, foreign material, stones, contrasting classes and blending classes by grade. Codex uses different moisture ceilings according to climate and storage practice. Atlas preserves the named grade, governing edition, lot and sublot, sample basis, moisture method, defect breakdown, inspector or laboratory, certificate and date. A seller's grade statement without that evidence remains a claim, not a verified result.

A standard does not establish a delivered kidney-bean price

USDA and Codex limits define classification and quality boundaries; they do not establish crop availability, colour retention, cooking performance, food-safety status, transaction value, freight or destination cost for a current lot. A delivered comparison still needs permitted current observations for the exact class and form, crop year, grade and test evidence, package, origin, quantity, currency, Incoterm, destination, delivery window, route costs and information vintage. Atlas withholds a physical estimate when those observations or usage rights are missing.

Questions procurement teams ask

Are Dark Red and Light Red Kidney beans the same U.S. class?

No. USDA lists Dark Red Kidney and Light Red Kidney as separate classes with distinct descriptive characteristics. White Kidney is another separate class.

Does U.S. No. 1 prove a specific kidney-bean lot conforms?

No. It names a grade and its limits. Conformity still needs lot identification, representative sampling, inspection or testing and a certificate tied to the goods offered.

Why do Codex and USDA show different moisture numbers?

They serve different scopes. USDA's bean grade table uses an 18-percent maximum for the named kidney-bean classes, while Codex provides 15- and 19-percent bean limits for different climates and storage practices. The applicable contract and destination rule must be explicit.

Which fields make kidney-bean offers comparable?

Class and species, cultivar where available, crop year, dry or canned form, whole or split condition, grade and governing edition, moisture and defect results, contrasting and blending classes, package and lot, sampling and inspection evidence, origin, quantity, currency, Incoterm, destination, delivery window and evidence date.
