Buying Kabuli chickpeas: turn a size label into a testable specification

A buyer orders Kabuli chickpeas for clear retail packs. Two offers both say 9 mm, but one includes a sieve report and the other includes only a photograph. The prices look comparable; the evidence does not. Before negotiating the final rate, the buyer needs to know what that size description measures, which lot it represents and how the delivered goods will be checked.

A useful purchase specification connects the commercial description to a repeatable measurement. It also keeps size, condition and intended use separate. Large seeds can still contain defects, and an attractive sample cannot establish the composition of an entire consignment.

Ask what the millimetre number means

The Canadian Grain Commission's chickpea sizing procedure reports the percentage by weight retained on a specified sieve. It uses a representative portion of the cleaned sample and requires the requested sieve size to be identified. Its examples include 8, 9 and 10 mm round-hole sieves. This provides a useful model for describing a test; it does not establish a universal acceptance threshold for every commercial order.

Ask the seller to state the aperture, hole shape, preparation method and retained percentage. If several fractions are reported, clarify whether the results are cumulative retention or separate size bands. A cumulative result at one aperture should not be added to another as though they describe non-overlapping quantities.

Seed count answers a different question: how many seeds are present in a defined mass or other stated sample basis. It can be an agreed commercial measure, but it should not silently replace a sieve result. Record the exact method used for each quoted figure rather than converting a size name into a count without evidence.

Keep the sample basis visible

A pre-cleaning sample and finished packed goods may give different size distributions. Government of Saskatchewan guidance specifically notes that size proportions before cleaning may differ from those measured after the cleaner. For purchasing, the practical question is which condition the offer and acceptance test represent.

Specify whether the tested material is the lot before cleaning, after grading or in its final packaging. Give every submitted sample a lot reference, sampling date and preparation description. Where an offer covers several production lots, ask for the relationship between each result and the quantities offered. Avoid attaching one favourable result to an unidentified balance of stock.

The Commission's grading guidance uses the cleaned sample as the weight basis for grading percentages and calls for representative portions divided from it. Consequently, a report should make the denominator clear. A percentage based on incoming gross material is not automatically comparable with the same percentage calculated after removable material has been taken out.

Give defects their own lines

A size specification should sit beside a condition specification. Ask for separately defined checks for foreign material, damaged seeds, mechanical damage and splits, colour and moisture, with the applicable method and agreed limits. Identify any end-use checks, such as a buyer's cooking trial, as additional requirements rather than assuming a size test covers them.

Definitions matter. The Canadian grading-factor guidance distinguishes damage from mechanical damage including splits, and does not classify hairline cracks and chipped seed coats as mechanical damage under that particular definition. A buyer who wants those appearance features controlled needs an explicit provision. Canadian grade terminology should be identified as Canadian terminology, not presented as a worldwide grade system.

Build a short acceptance record

The following fields turn an informal quality discussion into a record both parties can review. They are a proposed purchasing checklist, not an official grading form.

• Lot: supplier lot reference, quantity and packaging, with a defined link to the submitted sample.
• Size: named sieve method, sample condition, retained or passing basis, and the buyer's agreed limits.
• Condition: each defect definition, moisture method and required results, without combining unlike categories.
• Sampling: who selects the sample, at what stage and how portions represent the lot; retain sealed reference samples where agreed.
• Decision: who reviews the results, what triggers a hold, and the agreed route for a repeat or independent test.

Set those rules before loading. If two laboratories disagree, first compare lot identity, preparation, sieve details and calculation basis. Repeating a test without resolving those differences can produce another pair of incomparable numbers.

Send an enquiry that can be answered precisely

For a Kabuli chickpea enquiry, include the intended use, required size evidence, condition limits, pack format and destination. Request a lot-specific report alongside the price. The most useful offer is one whose declared quality can be checked against the delivered goods using a method agreed in advance.
