Q: FDA + FALCPA Big-9, what does my checkout actually need to show?

Three surfaces, three different requirements: Product Detail Page (PDP) , the ingredient panel must list the Big-9 allergens called out by name (e.g. “Contains: wheat, milk, eggs”). If processed on shared equipment, add “May contain: tree nuts, peanuts.” This is FDA-mandated for any packaged food sold across state lines, which is every shipped order. Cart + checkout , if the customer is signed in and has flagged an allergy in their account, fire a banner-level warning on cart load (not just a footnote). “You’ve flagged a peanut allergy. The items in your cart are made on shared equipment with peanuts. Continue?” Force an explicit acknowledgement checkbox before order placement. Shipping label + outer packaging , FDA requires the allergen statement on the consumer-facing label, not just the e-commerce page. Magento order export must include the allergen field so the label printer can print it on the carton. State-level rules add wrinkles: California Prop 65 for any product with certain chemical exposures (mostly relevant for chocolate / cocoa cadmium + lead). NYC Department of Health requires calorie labels in some categories. UK + EU have their own 14-allergen list which is wider than Big-9 (adds celery, mustard, lupin, mollusks, sulphites), if you ship UK/EU, multi-store-view Magento renders the localized allergen list per region.
