Allergen Compliance for Export: UK, EU, and US Requirements Compared

Food businesses exporting to multiple markets must comply with each market's allergen labelling requirements. UK, EU, and US regimes share a common foundation but differ in important details. Here's a practical comparison.

Allergen Counts by Jurisdiction

The US (FALCPA) requires declaration of 9 major allergens. The UK requires 14. The EU (FIC Regulation 1169/2011) also requires 14 — the same as the UK, as the UK's requirements were derived from EU law and are substantially unchanged post-Brexit. The five allergens required in UK/EU but not US: celery, lupin, molluscs, mustard, sulphur dioxide/sulphites.

Emphasis Requirements

UK and EU law require allergens to be emphasised within the ingredient list — typically bold. US FALCPA has no emphasis requirement; a "Contains" statement or common-name mention in the ingredient list suffices. For export labels, formatting to UK/EU standards (bold allergens in ingredient list plus a "Contains" statement) satisfies all three regimes.

PPDS and Online Sales

UK law introduced PPDS-specific requirements under Natasha's Law (full ingredient list on packaging, emphasised allergens). The EU has separate requirements for food sold at a distance (online) under FIC Article 14. US law does not have a direct PPDS equivalent, though FDA guidance for online sales requires pre-purchase allergen disclosure.

Designing for All Markets

The most efficient approach for export food businesses is to design labels to the most stringent requirements across all target markets: 14 allergens, emphasised in the ingredient list, with a "Contains" statement. This satisfies UK, EU, and US requirements simultaneously and eliminates the need for market-specific label versions.

Precautionary Allergen Labelling Across Jurisdictions

Precautionary allergen labelling (PAL) — statements such as "may contain traces of" or "produced in a facility that also handles" — sits outside the main legislative frameworks in all three jurisdictions, yet it carries significant practical weight for export businesses. In the UK and EU, PAL is not formally regulated, meaning there is no prescribed wording, no mandatory format, and no legal obligation to include it. However, Trading Standards and food safety authorities in both markets expect PAL to be used only where a genuine, assessed cross-contamination risk exists, not as a blanket liability disclaimer applied to every product regardless of actual risk.

In the United States, the FDA has historically taken a similarly unregulated approach to PAL, though FASTER Act provisions and ongoing FDA guidance reviews have prompted discussion about standardising advisory labelling language. The practical implication for exporters is that PAL wording that reads clearly and specifically — naming the allergen and the source of risk — is more defensible in all three markets than vague, catch-all statements. Auditors and regulatory inspectors in the UK, EU member states, and the US all look more favourably on PAL that is traceable to an actual hazard analysis rather than applied wholesale across a product range.

For businesses managing multiple SKUs across export markets, the administrative burden of maintaining accurate PAL statements can become substantial. Each product requires an up-to-date hazard analysis that accounts for raw material sourcing, production scheduling, and shared equipment. When suppliers change or production lines are reconfigured, PAL statements must be reviewed and updated accordingly. Building this review into a structured product management workflow — ideally linked directly to your Shopify product records — reduces the risk of outdated advisory labelling reaching customers in regulated markets. Allergen Matrix supports this by allowing PAL notes to be stored and updated at the product level, visible to your fulfilment and customer service teams.

Ingredient Naming and Recognised Common Names

One area where UK, EU, and US requirements diverge in ways that can catch exporters off guard is the acceptable naming of allergen-containing ingredients. US FALCPA requires that the common or usual name of the food source be used — so an ingredient derived from milk must be identified using the word "milk," not a technical derivative name alone. This means that casein, whey, and lactalbumin must all be accompanied by a parenthetical milk declaration if the common name does not make the source obvious to a typical consumer. The regulation is precise about this, and failure to use the correct common name is a routine basis for FDA warning letters.

UK and EU requirements under FIC operate slightly differently: emphasis is placed on declaring the allergen substance itself within the ingredient list, typically by naming the allergenic source in a way that is unambiguous. The regulation provides reference lists of substances and products causing allergies or intolerances, and ingredients derived from those substances must be labelled accordingly. In practice, this means that an ingredient list referencing "skimmed milk powder" satisfies the milk declaration requirement because the source is explicit in the ingredient name itself. However, where derivative names are used — such as lactose or casein — the milk origin must be made clear, mirroring the US requirement in effect if not in exact legal language.

For exporters writing a single ingredient list intended to satisfy all three markets, the safest approach is to ensure every allergenic ingredient is named in a way that explicitly identifies its allergen source, without relying on consumer familiarity with technical or trade names. This applies equally to less obvious derivatives: barley malt extract must be identified as containing gluten, and refined lupin flour must be declared as lupin. Taking the time to audit ingredient naming conventions across your entire product range before entering new export markets is time well spent and avoids costly label corrections after launch.

Record-Keeping and Audit Trails for Export Compliance

Regulatory compliance in allergen labelling is not only about what appears on a label — it is equally about demonstrating, when required, how that information was verified and maintained. In the UK, the Food Standards Agency and local Trading Standards officers have the authority to request documentation supporting the accuracy of allergen declarations. EU member state competent authorities have equivalent powers under official controls regulations. The FDA, for its part, can request records as part of FSMA inspections or import examinations. In all three jurisdictions, an inability to produce supporting documentation is treated as a compliance failure in its own right, separate from any error on the label itself.

For export businesses, this creates a practical requirement to maintain product-level records that link label claims to verified supplier information. This means holding current allergen declarations from raw material suppliers, records of any reformulations, and evidence of internal review processes each time a label is updated or a supplier changes. The documentation chain needs to be accessible quickly — regulatory inspections and import holds do not typically allow extended time for businesses to locate records from disparate filing systems. A well-organised digital record that connects each product to its allergen data, supplier declarations, and label version history is significantly more defensible than a collection of email threads and spreadsheets.

Shopify-based food businesses have an opportunity to integrate this record-keeping directly into their product management workflow. Rather than maintaining allergen data in a separate system that can fall out of sync with live product listings, tools that attach allergen information directly to Shopify product records ensure that the data customers and regulators see is the same data your team is actively managing. Allergen Matrix is built around this principle — allergen declarations, precautionary statements, and compliance notes live at the product level, reducing the risk of discrepancies between your operational records and your customer-facing listings.

Handling Reformulations Without Breaking Compliance

Product reformulation is one of the most common triggers for allergen labelling errors in export markets. When a manufacturer changes a raw material supplier, adjusts a recipe, or responds to a supply chain disruption by substituting an ingredient, the allergen profile of the finished product may change — sometimes in ways that are not immediately obvious. A switch from one oil supplier to another, for example, might introduce a sesame cross-contamination risk that was not present before. In export contexts, where label changes may require coordination across multiple language versions, market-specific regulatory filings, and fulfilment centre stock rotations, the window between a formulation change and an updated label reaching all customers can be dangerously wide.

Best practice for export businesses managing reformulations is to treat every ingredient or supplier change as a formal trigger for an allergen review, not an optional step. This review should happen before production of the reformulated product begins, not after. In regulated markets, selling a product with an inaccurate allergen declaration — even temporarily, and even without intent — constitutes a breach of food labelling law. The consequences range from voluntary withdrawal to formal recall, both of which carry significant reputational and financial costs that far outweigh the effort required to maintain a robust pre-production review process.

Building reformulation review into your Shopify product workflow helps ensure that changes made at the recipe or supplier level are captured before updated products go live for sale. When your allergen data is managed within your Shopify environment rather than in a disconnected spreadsheet, your team is prompted to review and update declarations as a natural part of the product update process. This closes the gap between operational change and customer-facing compliance, which is precisely where the most avoidable allergen labelling errors occur in practice.
