FALCPA Compliance for D2C Ecommerce Food Brands Selling in the US

Direct-to-consumer food brands selling packaged products online in the US must comply with FALCPA allergen labelling requirements. Here is what DTC ecommerce brands need to know.

The direct-to-consumer food market has grown significantly, with brands selling packaged food directly to consumers via Shopify, their own websites, and subscription boxes. Every packaged food product sold in the US must comply with FALCPA regardless of the sales channel.

FALCPA Applies to the Product, Not the Channel

FALCPA requires allergen labelling on the physical product packaging. Selling online rather than through retail stores does not create an exemption. If your product is a packaged food that will be consumed in the US, the label must comply with FALCPA.

What a FALCPA-Compliant Label Requires

The label must declare the presence of any of the nine major US allergens: milk, eggs, fish, shellfish, tree nuts, wheat, soybeans, peanuts, and sesame. The declaration must appear either:

  • Within the ingredient list with the allergen name in plain language (e.g., "flour (wheat)")
  • In a separate "Contains:" statement following the ingredient list (e.g., "Contains: wheat, milk, eggs")

Both formats are acceptable. The Contains statement format is the most common for DTC brands because it is easy for consumers to read quickly.

Online Store Allergen Information

While FALCPA governs physical labelling, FTC guidelines and consumer expectations mean that allergen information on your product pages is also important. List allergens prominently in your product descriptions. Customers with allergies review product pages before purchasing.

Subscription Box Considerations

Subscription food boxes often bundle multiple products. Each individual product must carry its own compliant FALCPA label. The box itself may also benefit from a summary of allergens across all included products for subscriber transparency.

Cross-Contact Disclosure and Voluntary Advisory Statements

Cross-contact occurs when an allergen is unintentionally transferred to a food product during manufacturing or handling, and it is one of the most nuanced areas of allergen compliance for DTC brands. FALCPA does not require manufacturers to include advisory statements such as "May contain traces of peanuts" or "Manufactured in a facility that also processes tree nuts," but many brands include them anyway to manage consumer expectations and reduce liability. If you choose to use advisory statements, they must be truthful and based on a genuine assessment of your manufacturing environment and processes.

The FDA has been clear that voluntary advisory statements should never be used as a substitute for good manufacturing practices. If you can eliminate cross-contact risk through improved procedures, segregation, or dedicated equipment, that is always the preferred approach. Using a "may contain" statement to cover inadequate production controls is not considered acceptable practice and does not shield a brand from regulatory scrutiny or civil liability should a consumer be harmed.

For DTC brands producing at scale or co-manufacturing with third parties, it is worth requesting a written allergen control plan from your co-packer. Understanding their cleaning validation procedures, scheduling of allergen-containing runs, and staff training protocols will help you determine whether an advisory statement is genuinely warranted. Document your own assessment and review it at least annually or whenever your formulation, supplier, or production facility changes.

Ingredient Supplier Changes and Label Accuracy

One of the most common sources of allergen labelling errors for growing DTC brands is an undisclosed change from an ingredient supplier. A supplier may reformulate an ingredient, switch a sub-ingredient, or change their own manufacturing setup in ways that introduce a new allergen into your product without any obvious notification. This is a significant compliance risk because the allergen information on your label may become inaccurate without any deliberate change on your part.

Building a robust supplier communication process is essential. Request allergen declarations in writing from every ingredient supplier and specify that they must notify you of any changes to their product formulation, sub-ingredients, or production environment before those changes take effect. Many brands use a supplier questionnaire that covers all nine FALCPA allergens, voluntary advisory statements the supplier uses, and whether the ingredient has been reformulated in the last twelve months. Keep these documents on file and review them whenever you place a new purchase order or renew a supplier relationship.

When a change is confirmed, update your label artwork and your Shopify product page at the same time. Selling existing stock with an outdated label while new compliant packaging is being printed creates a window of non-compliance that regulators and consumers can both identify. If the allergen change is material — for example, a product that previously contained no wheat now contains wheat — consider whether existing customers on a subscription or repeat-purchase cycle need to be proactively notified by email before their next order is dispatched.

Labelling for Products Shipped Across State Lines

FALCPA is a federal law administered by the FDA, which means it applies uniformly to packaged food sold across all fifty states. However, DTC brands should be aware that some states impose additional food labelling requirements on top of federal standards, and selling direct to consumers means you are effectively distributing nationally from the moment your first out-of-state order is placed. Monitoring state-level developments is part of responsible compliance management for any brand growing beyond its local market.

California in particular has a history of enacting food safety and labelling regulations ahead of federal action. Proposition 65 requires businesses to provide warnings about significant exposures to chemicals that cause cancer, birth defects, or other reproductive harm, and some food ingredients and contaminants fall within its scope. While Prop 65 is separate from allergen law, it illustrates that compliance for DTC brands selling into California requires attention beyond FALCPA alone. Consulting a food regulatory attorney familiar with multi-state DTC sales is a worthwhile investment as your order volume grows.

From a practical Shopify perspective, geo-targeted compliance is difficult to implement at the product page level. The most straightforward approach is to ensure your label and your product descriptions meet or exceed the most stringent applicable standard for all customers, rather than attempting to serve different content to customers in different states. This simplifies your content management and ensures no customer receives less information than they are entitled to.

Managing Allergen Information Across a Growing Product Catalogue

As a DTC food brand scales, the complexity of managing accurate allergen information increases significantly. A brand that launches with two or three SKUs can manage label accuracy manually, but once a catalogue reaches ten, twenty, or fifty products — each with its own formulation, supplier chain, and label artwork — the risk of errors compounds. Product variants, seasonal editions, and reformulated recipes each require their own allergen review and update cycle, and keeping your physical labels, your Shopify product descriptions, and any printed marketing materials synchronised is a genuine operational challenge.

Establishing a clear internal process is the foundation of good catalogue management. Assign ownership of allergen data to a specific person or role within your business, whether that is a founder, operations manager, or product development lead. Create a master allergen matrix document that maps every SKU to its declared allergens and any voluntary advisory statements, and treat that document as the single source of truth for all downstream content including label copy and ecommerce product pages. Review the matrix whenever a new product is added, a formulation changes, or a supplier update is received.

Technology can significantly reduce the manual burden of keeping allergen information accurate and visible to customers. Displaying a clear allergen summary on each Shopify product page — one that is easy to scan and updated in real time from your master data — reduces the chance that a customer with an allergy purchases a product that is not safe for them. It also demonstrates to your customers that you take allergen transparency seriously, which builds trust and reduces the volume of pre-purchase allergen enquiries your customer service team needs to handle. Allergen Matrix is built specifically to help Shopify merchants display this information clearly and consistently across their entire catalogue.

Preparing for FDA Scrutiny and Recalls

The FDA has enforcement authority over FALCPA compliance and can take action against brands whose products carry inaccurate or missing allergen declarations. Enforcement actions range from warning letters and import alerts to voluntary or mandatory recalls, and undeclared allergens are consistently among the most common reasons for food product recalls in the US. For DTC brands, a recall is particularly disruptive because your customer database is your direct channel — you are responsible for reaching every affected customer yourself, without the intermediary of a retail partner.

Preparing for this possibility before it arises is far more effective than responding reactively. Maintain a complete record of every batch or production run, including the lot code, production date, ingredient suppliers used, and the allergen declaration that appeared on that batch's label. If a recall becomes necessary, this information allows you to identify exactly which customers received affected products and to communicate with them quickly and accurately. Shopify's order data, combined with your production records, makes this tracing process feasible for DTC brands in a way that would be much harder through wholesale channels.

Conducting an internal allergen audit at least once per year is a practical step that many DTC brands overlook until a problem arises. Walk through your entire production process, review every ingredient against its current supplier declaration, compare your master allergen matrix to your live label artwork and Shopify product pages, and document any discrepancies found and corrected. This kind of proactive review demonstrates good faith regulatory compliance and, more importantly, catches errors before they reach a consumer.
