Chia is the seed of Salvia hispanica, and it is worth being direct about origin: it is not a Ukrainian commodity. Commercial volume comes from Paraguay, Bolivia, Argentina, Mexico and, increasingly, parts of East and Southern Africa. It appears in this catalogue because European buyers building a seed and plant-based portfolio buy it alongside the seeds that are Ukrainian, and because the compliance position around it is misunderstood often enough to be worth writing down.
That compliance position is the first thing to understand. Chia is a novel food in the European Union. It is authorised, which is not the same as being unregulated: it sits on the Union list with conditions of use attached, and those conditions have changed more than once since the first authorisation. A buyer who treats chia as an ordinary seed and writes a specification that ignores the Union list entry is carrying a real, if quiet, regulatory exposure.
Grades, cuts and calibration
Chia trades on purity, colour and moisture rather than on a formal grade ladder. There is no international grading standard in general use, so the parameters below are the ones that actually appear in contracts.
Colour separates black, white and mixed. Black is the default and the cheapest; white is a separate variety line, sells at a premium and is bought where the seed is visible in a pale product. Both are the same species. A lot sold as black will always contain some pale seed, and the contract should state the tolerated percentage of off-colour rather than pretend it is zero.
Purity is quoted as a percentage of clean seed after removal of foreign seed, stem, dust and stone. The commercial range runs from about 99.0 percent on a general-purpose lot to 99.9 percent on a lot sold for retail packing. The last tenth of a percent is expensive because it is removed by optical sorting rather than by air and sieve.
Moisture is the parameter that most affects handling. Chia is strongly hygroscopic and forms a mucilage gel on contact with water, so a seed that has picked up moisture in transit clumps, blocks dosing equipment and will not flow. The commercial ceiling is commonly 7 percent and better lots run below 6.5 percent.
Seasonality and availability
Chia harvests fall between April and August across the main origins, with Paraguayan and Bolivian crop arriving into Europe from roughly the third quarter and Mexican and African crop filling other parts of the year. Because origins are spread across hemispheres and latitudes, the material is effectively available year round, and the practical seasonality a European buyer feels is a price cycle rather than a supply gap.
The variable worth tracking is not availability but freshness. Chia is a high oil seed with an unusually high polyunsaturated fraction, and long storage at ambient temperature in a producing country before shipment is common. Ask for the harvest period and the date of cleaning and packing, not just the packing date, because seed can be cleaned and repacked years after it was grown.
What the buyer checks at intake
- Novel food status confirmed in writing. The supplier should state that the material is Salvia hispanica seed supplied for uses covered by the Union list entry, and your own specification should record the intended use. This is a document check, not a laboratory check, and it is the one most often skipped.
- Moisture, on arrival and not just on the certificate. Chia picks up water in transit more readily than most seeds. A lot that left at 6.2 percent can arrive above 7 percent if it crossed a temperature gradient in a container without desiccant.
- Purity by weighed separation. Screen a weighed sample and separate foreign seed, stem and mineral matter. Report the percentage rather than a pass or fail.
- Off-colour seed count on black or white lots. Count against the contracted tolerance. This is the parameter buyers of white chia dispute most often.
- Peroxide value and free fatty acid on the extracted oil. The only reliable indication of how old the seed really is.
- Salmonella and Enterobacteriaceae. Chia is consumed raw in most applications and has been the subject of recalls in the past. Treat it as a ready-to-eat raw agricultural commodity and sample it accordingly.
- Pesticide residue certificate against the current schedule. Origins outside the European Union do not necessarily grow to European residue limits, and the responsibility for compliance sits with the operator placing the product on the market.
- Heavy metals, with cadmium specifically. Small oilseeds accumulate cadmium from soil and the applicable maximum levels are set by the contaminants regulation.
Where it is used
Bakery uses whole seed in breads, crackers and bars, and this is where the authorisation conditions matter most, because processes that take the seed above certain temperatures were treated separately in the authorisation history over acrylamide formation. Check the current Union list entry against your process rather than assuming.
Beverages and dairy alternatives use whole seed for the mucilage it forms, in drinking yoghurts, seed drinks and gel-based products. The functional property being bought here is water binding rather than nutrition.
Breakfast and snacking take whole seed into cereals, granola, mueslis and seed mixes, generally at low inclusion. Retail packing of plain seed is a large outlet in its own right and drives the demand for the highest purity grades, because in a clear pack every stem fragment is visible.
Standards and routes
Chia arrives in Europe by sea container from South America and Africa and is then distributed by road. For a buyer sourcing through a European trader, the leg that matters is the inland one, and it is straightforward: a dry ambient palletised commodity moving as general cargo.
The recurring problem on the sea leg is condensation. A container loaded warm and sailed into cooler water will rain on its own cargo, and chia is the seed least forgiving of that because of its hygroscopicity. Container desiccant, a dry liner and a check of the moisture on arrival rather than on the origin certificate are the three controls that prevent it. Imports are subject to the official controls framework and, at times, to increased levels of official control on specific origins.
