Who is this for?

Travellers choosing a carry-on snack

A solid dark-chocolate bar is easy to compare by cocoa percentage and pack size. GOV.UK notes that food in hand luggage can obstruct X-ray images, so allow for a possible manual bag check.

Shoppers checking vegan and allergen labels

A vegan recipe does not establish suitability for a milk or other allergy. The Food Standards Agency advises checking allergen information separately, and individual dark-chocolate bars can carry “may contain” warnings.

Travellers choosing between plain and flavoured bars

Plain 70–75% cocoa bars and flavoured 70% bars offer different ingredient lists as well as different tastes. Compare both the cocoa declaration and any additions, such as ginger or fruit.

What should you check?

Start with a cocoa percentage you expect to enjoy, then check the exact bar’s ingredients, allergen information and suitability for your journey.

PriorityWhat to checkYour needs
Cocoa and flavour Read the stated cocoa percentage. Check whether the bar is plain or includes flavourings or pieces of fruit or ginger. I would start with a 70–75% bar if I want to try a high-cocoa option; I would choose a higher percentage only if I already enjoy a more intense cocoa taste.
Hand luggage Choose a solid bar and check the rules for your departure and transfer airports. GOV.UK says food may require a manual bag check. I want a snack I can carry, while allowing time for a possible security check.
Ingredients and allergens Read the exact pack’s ingredient list, allergen declaration and “may contain” statement. Do not use a vegan label in place of allergen information, as the Food Standards Agency advises. If I am buying for someone with an allergy, the individual bar’s label matters more than a brand name or vegan badge.
Sourcing claims Look for a sourcing claim on the particular bar, such as Divine’s stated Fairtrade ingredients. Check cocoa and allergen information separately. If sourcing matters to me, I want the claim to apply to the bar I am choosing.

Common buying mistakes

  • Treating “vegan” as an allergy guarantee

    Vegan-labelled dark chocolate can still carry precautionary allergen warnings. The Food Standards Agency says vegan labelling alone should not replace allergen information.

    Read the ingredients and allergen statements on the exact pack, especially when buying for someone with a milk or nut allergy.

  • Assuming food never gets an extra security check

    According to GOV.UK, food in hand luggage can obstruct X-ray images and lead to a manual bag check.

    Allow time for a possible check and confirm the rules that apply to your departure and any transfer airport.

  • Choosing by cocoa percentage alone

    Two bars labelled 70% cocoa can have different additions and allergen declarations: Montezuma’s ginger and cherry bars, for example, list soya and precautionary warnings.

    Check flavour additions and the full label alongside the cocoa percentage.

  • Assuming an online listing means airport stock

    A brand’s product listing or store-collection option does not establish that a particular airport shop carries the bar.

    If you want an exact product, check the relevant airport retailer or buy it before travelling.

Frequently asked questions

Can I take a solid dark-chocolate bar in hand luggage at a UK airport?

GOV.UK does not list an ordinary solid chocolate bar as a prohibited hand-luggage category, but says food can obstruct X-ray images and may require a manual bag check. Check the rules for your departure airport and any transfer before travelling.

Can I bring dark chocolate into Great Britain from abroad?

GOV.UK says chocolate and confectionery can be brought into Great Britain from any country without restrictions, except products made with a lot of unprocessed dairy ingredients. Great Britain means England, Scotland and Wales; check Northern Ireland’s rules separately if that is your destination.

Does a vegan label mean a dark-chocolate bar is suitable for a milk allergy?

No. The Food Standards Agency says vegan labelling alone should not be used instead of allergen information. Lindt says its vegan-recipe EXCELLENCE 70% bar is not suitable for people with a milk allergy, while Divine’s 70% bar states that it may contain milk; read the exact pack.

How should I store a dark-chocolate bar while travelling?

Follow the instructions on the bar you buy. M&S advises keeping its 75% bar in a cool, dry place away from sunlight.
