EU Allergen Labeling Guide: Regulation (EU) No 1169/2011 Rules

Navigating food packaging compliance across the European Union requires strict adherence to Regulation (EU) No 1169/2011 on the provision of food information to consumers (FIC). For food business operators (FBOs), managing mandatory allergen declarations is a critical legal responsibility. Misclassifying an allergen derivative or failing to highlight specific ingredients correctly can trigger immediate product recalls, retail delistings, and administrative fines across Member States.

Mandatory allergen declarations under Article 9(1)(c) and Annex II

Article 9(1)(c) of Regulation (EU) No 1169/2011 mandates declaring any ingredient or processing aid derived from substances listed in Annex II that cause allergies or intolerances. This requirement applies whenever the substance remains present in the finished product, even in an altered form. Annex II maintains an exhaustive list of 14 allergen categories, covering cereals containing gluten, crustaceans, eggs, fish, peanuts, soybeans, milk, tree nuts, celery, mustard, sesame seeds, sulphur dioxide and sulphites, lupin, and molluscs.

While the mandate is comprehensive, Annex II explicitly defines scientific exemptions for derivatives where industrial processing eliminates allergenic potential. For example, wheat-based glucose syrups including dextrose, wheat-based maltodextrins, glucose syrups derived from barley, fully refined soybean oil and fat, and fish gelatine used as a carrier for vitamin preparations are legally exempt from allergen labeling under Annex II. FBOs must verify that supplier ingredients conform precisely to these statutory definitions.

Formatting and typesetting rules under Article 21

Article 21(1) sets exact formatting rules for allergen presentation on physical packaging. Allergen ingredients must appear directly within the list of ingredients and must be emphasized through a typeset that clearly distinguishes them from the rest of the text. FBOs typically achieve this distinction using bold fonts, contrasting font styles, or background highlighting.

Under Article 21(1) third subparagraph, where several ingredients or processing aids in a food originate from a single Annex II substance, the label must make the origin clear for each individual constituent. For example, a recipe containing wheat flour and wheat starch must emphasize the word wheat in both entries. If a product is exempt from carrying an ingredient list under Article 19, Article 21(1) second subparagraph requires displaying the word contains followed immediately by the name of the Annex II substance.

Legibility and packaging area rules under Article 13 and 16

On standard packages, mandatory text including allergen declarations must be printed in characters with an x-height equal to or greater than 1.2 mm. For small packaging whose largest surface area is less than 80 sq cm, the minimum required x-height drops to 0.9 mm.

Specific packaging exemptions exist, but allergen declarations remain strictly enforced. Under Article 16(2), packages with a largest surface area under 10 sq cm are exempt from presenting a full list of ingredients. However, Article 16(2) explicitly mandates that allergen information under Article 9(1)(c) must still appear directly on the package. Similarly, under Article 16(1), reusable glass bottles indelibly marked must retain mandatory allergen references.

Compound ingredients and distance selling under Annex VII and Article 14

Formulators often rely on compound ingredient rules under Annex VII, Part E. Compound ingredients constituting less than 2% of the finished product are generally exempt from displaying a full sub-ingredient list. However, point 2 of Annex VII Part E specifies that this exemption applies without prejudice to Article 21. Any Annex II allergen present in a compound sub-ingredient must be declared on the outer label regardless of percentage.

Distance selling and e-commerce workflows are regulated under Article 14(1). For prepacked foods sold via websites or digital platforms, mandatory allergen information must be available before the purchase is concluded, at no additional cost to the consumer. Furthermore, Article 14(1)(b) requires that all mandatory particulars remain available at the exact moment of physical delivery.

Comparison of Annex II EU allergen categories and scientific exemptions

Managing allergen declarations requires evaluating ingredients against Annex II categories, specific legal exclusions, and mathematical concentration limits. The following comparison outlines the core rules under Regulation (EU) No 1169/2011.

Allergen Category (Annex II)	Legal Scope and Covered Substances	Specific Scientific Exemptions	Labeling Threshold
Cereals containing gluten	Wheat (spelt, khorasan), rye, barley, oats	Wheat glucose syrups, maltodextrins, barley syrups, spirit distillates	Any detectable level
Crustaceans	All crustaceans and products thereof	None	Any detectable level
Eggs	All egg products	None	Any detectable level
Fish	All fish species and products thereof	Fish gelatine for vitamin carriers or wine/beer fining	Any detectable level
Peanuts	All peanut products	None	Any detectable level
Soybeans	All soybean products	Fully refined soybean oil/fat, soybean tocopherols (E306), phytosterols	Any detectable level
Milk (including lactose)	All dairy products	Whey for spirit distillates, lactitol	Any detectable level
Tree nuts	8 listed nuts (almonds, hazelnuts, walnuts, cashews, pecan, Brazil, pistachio, macadamia)	Nuts used for making alcoholic distillates	Any detectable level
Celery	Celery stalks, leaves, seeds, celeriac	None	Any detectable level
Mustard	Mustard seeds, powder, condiment	None	Any detectable level
Sesame seeds	Whole seeds, oil, paste (tahini)	None	Any detectable level
Sulphur dioxide & sulphites	Direct SO2 additives and carry-over sources	Exempt at or below 10 mg/kg or 10 mg/L total SO2	Exceeding 10 mg/kg or 10 mg/L in finished product
Lupin	Lupin flour, seeds, protein	None	Any detectable level
Molluscs	Clams, mussels, oysters, squid, snails	None	Any detectable level

Understanding these specific exclusions prevents unnecessary allergen warnings, protects brand credibility, and maintains full compliance with EU food safety requirements.

Frequently Asked Questions

Do I have to bold wheat in the ingredient list if my product is certified gluten-free? Yes. Under Article 21(1) of Regulation (EU) No 1169/2011, the source cereal must always be highlighted in the ingredient list (e.g. wheat) whenever present, even if the finished product meets the gluten-free threshold of under 20 ppm set by Regulation (EU) No 828/2014.

Are wheat-based glucose syrups exempt from allergen labeling in the EU? Yes. Under Annex II, point 1(a), wheat-based glucose syrups including dextrose are explicitly exempt from mandatory allergen labeling, provided the processing has not increased their allergenicity.

Do we need to list allergens for sub-ingredients making up less than 2% of the recipe? Yes. Annex VII, Part E, point 2 exempts sub-ingredients of compound ingredients under 2% from detailed listing, but explicitly states this applies without prejudice to Article 21. Any Annex II allergen present in any quantity must be declared.

How do I calculate the 10 mg/kg sulphite limit for carry-over SO2? Under Annex II, point 12, the 10 mg/kg (or 10 mg/litre) threshold is calculated as total SO2 in the finished product as proposed ready for consumption. You must sum added sulphites and all carry-over SO2 from ingredients like dried fruit or starches.

Do we have to bold the allergen name every time it appears in the ingredient list? Yes. Under Article 21(1) third subparagraph, where multiple ingredients originate from a single Annex II substance, each individual reference must be highlighted (e.g. wheat flour, wheat starch).

Is coconut considered a tree nut allergen under EU food labeling law? No. Annex II, point 8 lists exactly eight tree nuts: almonds, hazelnuts, walnuts, cashews, pecan, Brazil, pistachio, and macadamia. Coconut is not classified as an Annex II allergen in the EU.

Do online grocery websites need to display allergen info before a customer buys? Yes. Under Article 14(1)(a), mandatory allergen information must be available on distance selling material before the purchase is concluded, at no extra cost to the buyer.

What is the minimum font size for allergen declarations on small packages under 80 sq cm? Under Article 13(2), mandatory text on packages with a largest surface area under 80 sq cm must have an x-height of at least 0.9 mm, compared to 1.2 mm for standard packaging.

Is spelt classified as wheat under EU Annex II allergens? Yes. Annex II, point 1 explicitly classifies spelt and khorasan wheat as wheat. Labels must include a reference to wheat, such as spelt (wheat).

Can we use a ‘may contain’ label instead of running a full allergen wash on the line? No. Precautionary Allergen Labeling (PAL) must only be used following a thorough HACCP hazard assessment where cross-contamination cannot be prevented. Under Article 36(2), PAL must not be misleading or ambiguous.
