Technical guide to Imperial Osetra Caviar: species identity, quality, preservation, CITES traceability and lot documentation.
Caviar is the product made from fish eggs of the Acipenseridae family treated with food-grade salt. Codex CXS 291-2010 links the usual name Ossetra/Osetra to caviar from Acipenser gueldenstaedtii and Acipenser persicus, subject to the law and custom of the market where it is sold.
“Imperial” is used commercially as a selection or grade descriptor, but it is not by itself a universal Codex grade. A professional offer should therefore translate the term into verifiable criteria: species, grain size and uniformity, colour, firmness, salt content, sensory condition, lot and shelf life.
In foodservice, Osetra caviar is mainly positioned for fine dining, premium hospitality, catering and specialist retail. Commercial quality depends on sensory profile as well as legal traceability, package integrity and cold-chain control.
Confirm scientific name and species code.
Eggs treated with food-grade salt and assigned to a defined lot.
Define grain size, colour, firmness and the “Imperial” criterion in the specification.
Verify CITES label, origin, plant and lot number.
Maintain the specified temperature conditions through storage and transport.
Codex CXS 291-2010 sets a salt content of 3–5 g/100 g for sturgeon caviar and requires size and colour characteristics consistent with the species. Lot examination also considers odour and flavour, consistency, broken eggs or fluid and foreign matter.
For a B2B specification, the word “Imperial” should be accompanied by measurable parameters. The file should state species, agreed grain-diameter range where applicable, uniformity, colour, texture or firmness, salt content, pack format, net weight, production date, shelf life and acceptance tolerances.
A buyer should distinguish an attractive commercial description from a contractual specification. The latter is what makes offers comparable and allows the delivered lot to be verified.
As an international reference, CXS 291-2010 states +2 °C to +4 °C during packing, storage and retail, and 0 °C to −4 °C for wholesale storage and transportation. Producer specifications, destination rules and declared shelf life prevail where they impose tighter conditions.
CITES traceability is central to legal international trade in sturgeon caviar. The non-reusable label on the primary container identifies, among other elements, species code, source, country of origin, year, registered plant and lot. Those data should be consistent with the applicable permits or certificates and commercial documents.
The lot file should connect product, plant, CITES label, sanitary certificate where applicable, temperature conditions, packing and destination. A mismatch in species, CITES code, lot or documentation can prevent acceptance even when sensory quality is high.
| Element | Verification |
|---|---|
| Species | Confirm scientific name; Codex links Ossetra to A. gueldenstaedtii and A. persicus. |
| “Imperial” grade | Define contractually what it means: grain size, colour, firmness, uniformity or other agreed criteria. |
| Salt | Declare and verify content; Codex sets 3–5 g/100 g for product covered by CXS 291-2010. |
| Condition | Check membrane firmness, broken eggs, free fluid, odour and flavour. |
| Pack and lot | Verify net weight, closure, date, shelf life and documentary consistency. |
| CITES | Verify non-reusable label, species code, source, origin, plant and lot. |
Sturgeon caviar moves through a regulated international market in which species identity and traceability matter as much as gourmet positioning. Before quoting or purchasing, three layers should be separated:
| Market | Role | Context / period |
|---|---|---|
| Product | SPECIFICATION | Species, grain size, colour, salt, texture, packing and shelf life should be defined contractually. |
| International trade | CITES | Permits, certificates and labelling depend on origin, source and trade route. |
| Destination | MARKET ACCESS | Sanitary, food-labelling and import requirements should be confirmed for the buyer country. |

Scientific species, definition of the Imperial grade, agreed grain size, colour, texture, salt, format and net weight.
Applicable CITES label and documentation, lot code, plant, country of origin, sanitary certificate where required and shelf-life statement.
Packing condition, temperature record or evidence, storage instructions and transport documents tied to the same lot.
Osetra identifies caviar from species recognized by Codex as Acipenser gueldenstaedtii and Acipenser persicus. “Imperial” is a commercial descriptor and should be defined in the specification through grain size, colour, firmness, uniformity or other agreed criteria.
CXS 291-2010 sets salt content at not less than 3 g/100 g and not more than 5 g/100 g for the product covered by the standard.
Codex CXS 291-2010 gives 0 °C to −4 °C as the reference for wholesale storage and transportation. Producer instructions and destination rules must also be followed.
The CITES label on the primary container identifies elements such as species, source, country of origin, year, registered plant and lot, which should match the applicable trade documentation.
Beyond species, grain size and salt, checks include uniformity, grain firmness, broken eggs or free fluid, odour, flavour, package integrity and shelf life.
At minimum, request the technical specification, species and lot identification, applicable CITES documentation, sanitary certificate where required, packing and shelf-life information and evidence of storage and transport conditions.
