On a hybrid caviar’s CITES label, the male parent comes first: his species code precedes the female’s. Even the year needs decoding. On a repacked tin, it records repacking, not harvest.
A label rewards close reading. It can tell you which roe is inside, what has been added, its declared origin and how the producer says to keep it. Start by separating two things: food information and wildlife traceability.
Read a caviar label in two layers
The food label describes what you will eat. The CITES label traces the wildlife product. Read both, because they answer different questions.
Food labelling law covers the product’s name, ingredients, allergens, quantity and other required information. CITES uses a coded label on the primary container: the tin or jar touching the caviar. Its framework calls for a non-reusable label, with visible evidence of opening if the label does not seal the container.
In the EU, retail information follows Regulation (EU) No 1169/2011. Great Britain uses its assimilated, amended version; Northern Ireland generally follows EU food law. In the US, FDA food rules and US Fish and Wildlife Service trade rules have separate roles. The labels and authenticity hub brings these subjects together.
A numbered teaching label
Teaching example, not a real label. Every bracketed entry and code component below is a placeholder, not a product specification or a model compliant label for any market.
| Field | What you might see | What to check |
|---|---|---|
| 1. Product name | [sturgeon caviar] | The food itself, beyond the brand. |
| 2. Species | [scientific name] | Match it to the species code. |
| 3. Ingredients | [roe (fish), salt, any additives] | Every ingredient, including preservatives. |
| 4. Nutrition | [nutrition declaration] | Units and serving basis. |
| 5. Net weight | [grams] | Food weight, without packaging. |
| 6. Date mark | [use by or best before: date] | Which kind of date? |
| 7. Storage | [validated temperature and opening instructions] | Can you maintain these conditions? |
| 8. Treatment | [pasteurised, if applicable] | Has heat treatment been used? |
| 9. Origin | [country of origin] | Roe origin versus repacking location. |
| 10. Responsible business | [operator name and address] | The accountable business and its role. |
| 11. Lot | [lot 000] | Retain for batch enquiries. |
| 12. CITES label | XXX/?/ZZ/YYYY/0000/000 |
Decode it; check for extra repacking information. |

The name and the species
Start with the food name, not the grandest lettering on the tin. Codex CXS 291-2010 covers salted roe of Acipenseridae, the true sturgeon family. It is an international reference standard, not automatically national law. CITES and US wildlife rules cover the wider order Acipenseriformes: sturgeons and paddlefish.
EU and UK customs classifications distinguish caviar from caviar substitutes under heading 1604, with subheadings 1604 31 00 and 1604 32 00 respectively. These govern international trade rather than providing a complete retail naming rule. Consumer descriptions must also meet the applicable food information law.
US FDA nonbinding guidance CPG 540.150 says unqualified “caviar” should mean salted sturgeon roe. For other fish, the fish name should have substantially equal size and prominence, as in “salmon caviar”. The guidance also addresses prominent disclosure of added artificial colour. This food naming guidance differs from the wildlife definition.
If the scientific name is missing, ask for it. Beluga refers to the species CITES lists as Huso huso; “Ossetra” alone does not establish species. For a hybrid, ask for both the male and female parents in words.
A scientific name is not compulsory on every caviar label under the EU’s fish marketing regulation. Regulation (EU) No 1379/2013, Article 35, does not extend its special consumer information requirements to caviar classified in heading 1604. General food labelling and CITES requirements remain separate.
Ingredients and fish allergens
Read the ingredients from the top: they appear in descending order by weight. Salt is an ingredient; sodium is a nutrient. Seeing both words elsewhere on the pack does not mean two separate additions. In EU and UK ingredient lists, additives normally appear as their function followed by their name or E number.
For domestic sale, EU Regulation (EC) No 1333/2008 permits boric acid (E284) and sodium tetraborate, or borax (E285), in sturgeon eggs only. The combined maximum is 4,000 mg/kg expressed as boric acid. Great Britain’s food additives register lists these authorisations; Northern Ireland follows the EU regime.
Imperial”, “Royal” and “Reserve” can dominate a tin without telling you its species.
For the United States, check the FDA’s current position on boron preservatives before relying on a label. An E number is not worldwide permission. When checking borax permissions, the destination market matters, not the producer’s nationality.
Fish must be emphasised within an EU or UK ingredients list, commonly in bold. US allergen law, including FALCPA, instead requires the fish species to be identified through the ingredient wording or a “Contains” statement. Bold type is not the equivalent federal requirement.
Nutrition and net weight
Compare equal weights before comparing salt figures. EU and UK nutrition panels give salt in grams per 100 g; US Nutrition Facts gives sodium in milligrams per labelled serving. Nutrition declarations are generally required, subject to national exemptions.
The EU legal conversion is straightforward: salt equals sodium multiplied by 2.5. As a purely mathematical example, 400 mg sodium equals 1 g salt equivalent. For the caviar itself, use the product’s own panel and the guide to salt in caviar.
Net weight measures the food, not its container. EU and UK labels use metric quantities; US retail labels generally state both metric and US customary quantities. Check the grams. A tin’s diameter is no measure of how much caviar it holds.

Dates, storage and heat treatment
“Use by” concerns safety; “best before” concerns quality. That is the distinction on EU and UK labels. Highly perishable foods that can become dangerous after a short period require a use-by date. Do not eat them after it. Neither date makes up for storage outside the stated conditions.
The US has no generally mandatory federal date-marking system for packaged caviar, and “use by” has no universal federal safety meaning. State requirements may differ. Follow the producer’s handling instructions and applicable local advice rather than transferring the EU interpretation to a US label.
Look for an actual storage temperature and separate instructions after opening. “Keep refrigerated” is not a complete plan. The printed date normally applies to the unopened product kept under its specified conditions; opening may introduce a shorter limit. Ask for missing instructions before buying, and consult the storage labelling rules.
“Pasteurised” means heat treatment intended to reduce microorganisms. It does not automatically mean shelf stable, so read the storage conditions. If heat treatment matters to your choice, ask whether it has been used. A long date alone cannot answer that question.
Origin, the business and the lot
An address tells you who the operator is, not necessarily where the farm is or where the roe originated. “Packed in” and “repacked in” describe operations. They do not turn imported roe into locally farmed roe. The distinction is explained in country of origin versus repacking.
General EU and UK origin rules are separate from the special rules for fresh fish. In the US, USDA AMS expressly excludes salt-cured caviar from its retail Country of Origin Labeling scheme. Separate customs marking and wildlife requirements still apply.
The lot number is your link to the operator’s batch records, whether for a query or a recall. Photograph it along with the rest of the label, and keep the reference until the caviar has been consumed.
The CITES code, briefly
The CITES code is a compact traceability record. In XXX/?/ZZ/YYYY/0000/000, the placeholders stand for species, source, origin country, year, registered plant and a final tracking reference. “Source” means the specimen’s documented origin category, not its country.
XXX and ZZ deliberately identify no real species or country; the question mark is not a valid source code. Repacked labels can require additional country information.
For initial packing, the year is the harvest year. For repacking, it is the repacking year. The repacker’s registration identifies that operation separately from origin. If repacking happens in a different country, its country code accompanies the repacker’s registration.
The final reference may be the repacking lot or the relevant CITES permit or certificate number. Hybrid codes put the male parent’s species code before the female parent’s code. Each element has a traceability purpose; none is a retail quality grade.
Resolution Conf. 12.7 (Rev. CoP17), Annex 1, sets out the labelling framework, implemented through national or regional law. US 50 CFR 23.71 governs imports, exports and re-exports rather than providing a universal domestic retail rule. For the full decoding method, read the CITES code explained.
Marketing claims and what the label cannot prove
“Imperial”, “Royal” and “Reserve” can dominate a tin without telling you its species. Nor do they supply a standardised legal quality grade under the rules discussed here. Ask for something measurable: the species, selection criteria or treatment behind the name. “Wild” and “natural” also need evidence; misleading claims remain subject to food law.
A QR code or website account is the producer’s claim unless it leads to independently checkable evidence. Compare what it says with the actual batch label. A general farm story cannot establish the contents or origin of every pack.
A CITES label supplies traceability information, rather than verifying the contents or guaranteeing food safety. An intact seal and an appealing appearance cannot establish safe handling throughout distribution. Compare all available label information, and take inconsistencies to the responsible operator.
Finally, destination matters. Switzerland, Japan, China, the UAE, Russia and Australia have domestic food rules distinct from their import requirements. A label prepared for one destination is not a universal compliance certificate.
