Cardamom Quality Specifications: Moisture, Oil and Foreign Matter

A Certificate of Analysis is the only part of a cardamom offer that is falsifiable. Photographs can be of someone else’s lot. Grade names are trade convention. But a COA makes specific numerical claims you can test on arrival — which is exactly why you should read it closely before the container ships, not after.

Here is what each parameter on a cardamom COA is actually telling you.

Moisture content

What it measures: water as a percentage of total weight.

Why it matters: moisture is the single most important number on the certificate, because it drives everything that can go wrong in transit. Pods that ship too wet arrive mouldy, and a sealed container crossing the tropics behaves like an incubator. Too dry and the pods become brittle, split during handling, and lose volatile oil — you paid for aroma and received dust.

Two practical points buyers miss:

• Ask when the reading was taken. Moisture measured at packing and moisture measured at loading can differ, especially if pods sat in ambient humidity between the two.
• Ask how it was measured. Oven-drying and handheld meters do not always agree. A meter is fine for process control; for a COA you want a laboratory method stated by name.

Volatile (essential) oil content

What it measures: the percentage of aromatic oil recoverable from the pods, typically by steam distillation and reported as ml per 100 g.

Why it matters: this is the closest thing to a direct measure of flavour strength. Two lots can look identical and grade identically while differing substantially in oil — and if you are extracting oil or formulating to a flavour target, this number is your real specification.

Oil content falls with age and with heat exposure. A high figure on a COA dated eight months ago tells you little about what is in the bag today. Always check the analysis date against the packing date.

Foreign matter

What it measures: anything in the lot that is not cardamom — stalk, stone, soil, plant debris, insect fragments.

Why it matters: beyond the obvious food-safety dimension, foreign matter is weight you paid cardamom prices for. A 2% foreign matter rate on a 20-tonne shipment is 400 kg of stalk and grit.

[PLACEHOLDER: state your own foreign matter target as a maximum percentage, and whether it is measured by weight or by count.]

Ask whether the limit is expressed by weight or by count, and whether “extraneous vegetable matter” (stalk from the same plant) is reported separately from true foreign matter. Many disputes are definitional rather than factual.

Defective and immature pods

What it measures: split, empty, shrivelled or under-ripe capsules as a percentage of the lot.

Why it matters: an empty pod weighs almost nothing but occupies grading space and dilutes aroma. Immature pods are also paler, which drags down the visual grade even when the rest of the lot is sound.

Aflatoxin and residues

What it measures: mycotoxin contamination (chiefly aflatoxin B1 and total aflatoxins), and depending on destination, pesticide residues.

Why it matters: this is the parameter most likely to get a shipment rejected at the border rather than merely discounted.

Two rules that will save you a rejected container:

1. Test to the destination, not to the origin. A lot that passes one market’s limits may fail another’s.
2. Confirm which tests are in-house and which are third-party. A supplier’s own laboratory is useful for process control. For a border, you generally need an accredited independent laboratory.

[PLACEHOLDER: state which of your tests are in-house and which go to a third-party accredited laboratory — and name the lab and its accreditation if you can.]

Colour and appearance

Largely a commercial rather than safety parameter, but it drives price. Green cardamom is valued for retained green colour, which is a proxy for careful drying. Sun-bleached or yellowed pods usually indicate heat or age.

Reading a COA properly

Work through it in this order:

1. Dates first. Analysis date, packing date, harvest season. A stale COA is the most common way a good-looking document misleads.
2. Lot identity. Does the COA reference a lot or batch number that also appears on the bags? If it does not, the certificate is not traceable to what you receive.
3. Method, not just result. “Moisture 11.2%” is a claim. “Moisture 11.2%, oven method, 105 °C” is a verifiable claim.
4. Who signed it. In-house, third-party, or unattributed.
5. Then the numbers.

Build the spec into the contract

The most useful thing you can do with these parameters is stop treating them as information and start treating them as terms. Write the accepted range for each into the contract, state the arbitration laboratory, and agree in advance what happens on a marginal fail — rejection, discount, or re-work.

A supplier who will put numbers in a contract is a different proposition from one who will only put them in a brochure.

Next, the paperwork that actually moves the container: Importing cardamom from Indonesia.
