Cumin seeds 99% purity means that by weight 99% of the lot is cumin seed and no more than 1% is stalks, stones, dust and foreign seed. It says nothing about moisture, volatile oil or pesticide residues. A grade name only becomes a specification when you attach numbers to it.
That applies to Europe and Singapore quality cumin, eagle coriander seeds and green fennel too. Each name is a trade habit. None is a standard.
What does cumin Europe quality specification mean?
European quality is not a defined grade. In practice it means 99% purity or better, low moisture, a clean colour, and, above all, a lot that can pass European residue limits. Those limits are set in EU law and change, so check the current rules with your importer or the competent authority before you contract; EU pesticide and MRL limits for spices explains how to approach it.
Write the specification in figures: purity, moisture, volatile oil, ash and acid-insoluble ash, plus the residue and microbiological tests you want. Name the test method for each, so the supplier's lab and yours measure the same thing.
What does Singapore quality cumin mean?
Singapore quality is a trade term for a cleaner grade than ordinary machine-cleaned cumin, with a purity level and use that differ from the European one. The difference is covered in the difference between Singapore and Europe bold quality cumin.
Because the term is loose, do not accept it in a contract. Instead state the purity you need and ask what the plant offers at that level, as what purity to ask for in cumin suggests.
What are eagle coriander seeds?
Eagle, badami and scooter are coriander grades, all names for the same crop sorted by colour, size and splits. Eagle is the better grade, with a light greenish-yellow colour, rounder seeds and fewer split seeds.
For a buyer the useful figures are the percentage of whole seed, the percentage of splits, volatile oil and moisture. How the grades differ is set out in eagle, badami and scooter coriander.
Why does fennel need a green colour grade?
Fennel is valued for colour. A fresh green seed signals careful harvest and drying; brown or yellow seed suggests age or poor drying. The market pays for green, but colour fades with storage, so a lot that matched at sampling can look different on arrival.
Colour is judged by eye or by a colour meter, so agree the method, a retained sample and a tolerance. Why green colour matters in fennel goes into the detail. Also specify seed size, purity and moisture.
How do you put it in a contract?
Convert each grade name into a line with a number, a test method and a tolerance. Agree a sealed pre-shipment sample that both parties keep, and decide in advance what happens if the arrival result differs. Pricing depends on the crop, the grade and the tests required, so the quote follows the specification, not the reverse.
Look also at why quality drops after the first container.
What if the arrival result differs from the sample?
Plan for it before you sign. Agree which laboratory is the referee, what tolerance applies between two results, and who pays for the retest. Without this, a small gap in purity or moisture can turn into a dispute that holds up the container.
A sealed sample from the loading, kept by you and by the supplier, settles most of these arguments quickly.
