Allergen labelling for export: the list is not the same list

Allergen labelling is the part of an export pack where a mistake stops being a compliance problem and becomes a safety one. It is also the part where Canadian exporters are most likely to believe they are already covered, because Canada's regime is rigorous and they have complied with it for years.

The regime being rigorous is not the same as it being universal. Every market that regulates food requires allergens to be declared, and no two lists are identical. A pack built against Canada's is compliant in Canada and is a hypothesis anywhere else.

Canada's rule, and the part exporters remember incorrectly

If a food allergen or gluten source is present in a prepackaged product that is required to carry a label, it must be declared on the label. That obligation does not extend to presence resulting from cross-contamination, which is handled separately and voluntarily.

That second clause is the one that gets misremembered, usually as permission. It is not. It is the boundary between a mandatory declaration, which covers what you deliberately put in, and a precautionary statement, which covers what might have got in by accident and which Canada treats as voluntary and heavily constrained.

The practical consequence for export is that a Canadian pack carries a mandatory declaration built from the Canadian list, and a precautionary statement built on Canadian expectations about when one is appropriate. Both are assumptions, and both need re-testing against the destination.

Where the lists diverge, and why the direction matters

The differences between national allergen lists are not random, and they are not symmetric in their consequences.

An allergen Canada requires that the destination does not is harmless on a pack. You declare something nobody asked for, which is at worst clutter.

An allergen the destination requires that Canada does not name is the failure case. The ingredient is in the product, it is not separately declared because Canadian rules did not call for it, and the pack is non-compliant in a way that no Canadian review would catch, because the Canadian review is working from the Canadian list.

That asymmetry is the whole reason this cannot be done by comparing your pack to your own regulations. It has to be done by taking the destination's list and checking your formulation against it, item by item, including items your Canadian process has no reason to track.

Regional differences are common in exactly the categories that matter for this route. Different markets treat molluscs, crustaceans and fish as one category or three. Sesame, buckwheat, celery, mustard and lupin appear on some national lists and not others. Sulphites are handled at different thresholds. None of this is exotic, and all of it is invisible from a Canadian label.

Precautionary statements do not transfer

"May contain" statements feel like a safety measure and function, in a regulatory sense, as a claim. Canada treats them as voluntary, subject to the general principles for labelling and advertising, and expects them to be truthful rather than defensive: a precautionary statement used where good manufacturing practice could have eliminated the risk is not a solution.

Other jurisdictions take different positions, ranging from permitted-and-common to prescribed-in-form to discouraged. A statement that reads as responsible in Canada can read as an admission elsewhere, or can be non-compliant for using wording the destination does not recognise.

There is also a commercial dimension that exporters meet late. A buyer's own customers, particularly in food service and institutional channels, may reject product carrying a precautionary statement regardless of what the regulator permits. That is a specification conversation, not a labelling one, and it is better had before the first order than after it.

"Free-from" claims raise the evidentiary bar

Gluten-free is the clearest example and the pattern generalises.

In Canada, a gluten-free claim is any representation in labelling or advertising that states, suggests or implies that a food is free of gluten, and to be represented as gluten-free a food must comply with the specific provision in the Food and Drug Regulations. The definition captures implication, not just the literal phrase, which means a design that gestures at gluten-free without saying it is still making the claim.

Two things follow for an exporter. The claim has to be supportable under the destination's rules and thresholds, which may differ from Canada's. And the claim travels with the artwork: a symbol or a visual cue that was assessed under Canadian rules goes onto a pack that will be assessed under different ones.

The same logic covers allergen-free claims generally, and it runs into an obvious tension with precautionary labelling, since a product carrying both a free-from claim and a "may contain" statement for the same allergen is making two statements that a reasonable reader cannot reconcile.

The declaration has to survive translation

An allergen declaration that is accurate in English and wrong in the destination's language is wrong, and this is a more common failure than it sounds because allergen names are exactly the words a general translator will render naturally, not legally.

Three specific risks.

**The regulated term is not the everyday word.** Destination rules name allergens in particular terms, and a synonym that any speaker would understand may not be the term the regulation uses. A reviewer checking compliance is checking for the prescribed word.

**Category boundaries move between languages.** Where one market's rules treat shellfish as a single category and another separates crustaceans from molluscs, the translation is not a word swap: it is a decision about which category the ingredient falls into, made by whoever is translating unless somebody made it first.

**Emphasis and formatting carry meaning.** Where allergens must be highlighted, bolded, grouped in a particular statement or placed in a specific position, the formatting is part of the requirement. A translation delivered as plain text loses it, and the layout is then rebuilt by someone who does not know it mattered.

The mitigation is to treat the allergen block as regulatory text with a specified source, not as copy. Get it from someone working from the destination's own rules, and have the final laid-out artwork checked as well as the text file.

The ingredient list is where most of this is decided

Allergen compliance is usually framed as a labelling exercise and is mostly a supply chain one. The declaration can only be as accurate as the knowledge behind it, and that knowledge lives with suppliers.

Three specific gaps recur:

**Compound ingredients.** An ingredient that is itself a formulation carries its own allergens, and whether they surface on your label depends on rules about when components must be broken out. Those rules differ by market.

**Processing aids and carriers.** Substances present for technical reasons, including carriers for flavours and colours, release agents and enzymes, are the items least likely to be on a specification sheet and entirely capable of carrying an allergen.

**Reformulation without notice.** A supplier changing a carrier or a source is not obliged to tell you unless your agreement says so. A product whose label was correct when it was printed can become incorrect because somebody else changed something.

For export the consequence is sharper than domestically, because the stock sits further away, moves more slowly and is harder to recall. A domestic error is caught in weeks. An export error is discovered in a market you cannot reach quickly, in a language you do not read, by somebody whose first call is to your buyer rather than to you.

Recall is the reason this sits above the other labelling work

Everything else on a pack fails commercially. An allergen declaration fails clinically, and the response is not a correction notice.

An undeclared allergen discovered in market triggers a withdrawal or a recall, and an export recall runs on somebody else's process in somebody else's language. Your importer executes it, the destination authority supervises it, and you find out what is happening through a party whose own licence is now involved.

The stock is distributed, the records of where it went belong to the distributor, and the timeline is set by a regulator you have never spoken to.

The cost is rarely the product. It is the listing, which is unlikely to survive, and the relationship with an importer who has just been through a regulatory event caused by a supplier. Both are harder to rebuild than a print run.

That is the argument for spending disproportionate effort here relative to the rest of the pack. Getting the net quantity wrong is embarrassing. Getting the allergen declaration wrong ends the market.

What a review should actually do

• Take the destination's allergen list, not Canada's, and check the formulation against it item by item
• Include compound ingredients, carriers and processing aids in that check, not only headline ingredients
• Establish the destination's position on precautionary statements before deciding whether to carry one
• Test every free-from claim, including implied ones, against the destination's threshold and its rules on implication
• Confirm the declaration appears in the language and form the destination requires, which is a separate question from whether it is accurate
• Put a change-notification obligation in supplier agreements, because the label is downstream of a formulation you do not control

That last one is the only item on the list that is not labelling work, and it is the one that prevents the failure nobody sees coming.

For seafood specifically there is a further wrinkle worth naming: species identification and allergen declaration are the same question wearing different clothes. A pack that is imprecise about which species is in it is imprecise about which allergen category applies, and both the customs authority and the allergic consumer are relying on the same sentence.
