Fairtrade-first snack shoppers
You want dark chocolate for a UK airport departure and need the claim on the exact pack to be clear, rather than relying on the brand's reputation.
Who is this for?
Travellers choosing by cocoa percentage
You are comparing dark bars around 70%, 75% or 85% cocoa while checking the Fairtrade claim separately from your flavour preference.
Gift buyers checking allergens
You are considering a boxed or filled chocolate gift and need to check for ingredients such as nuts and milk before buying it for someone else.
What should you check?
Plain dark bar
Choose it when: You want a compact airport snack and can check the exact bar's Fairtrade claim.
Bear in mind: A cocoa percentage describes the chocolate, not the scope of its Fairtrade claim.
Filled chocolate gift
Choose it when: You want a larger selection for sharing or gifting after security.
Bear in mind: Heathrow's Guylian Dark Praline Seashells contain hazelnut praline; its stated Fairtrade claim concerns cocoa.
Other sourcing claims
Consider them when: A particular flavour, cocoa percentage or brand sourcing approach matters more to you than a Fairtrade Mark.
Bear in mind: A company sourcing programme does not establish that the exact chocolate pack carries a Fairtrade Mark.
| Priority | What to check | Your needs |
|---|---|---|
| Fairtrade claim | Look for the mark on the exact pack and read which ingredients it covers. The Fairtrade Foundation says the classic black-background mark covers ingredients that can be Fairtrade certified; the Fairtrade Sourced Ingredient mark identifies a particular ingredient. | I want to know whether the claim applies to certifiable ingredients across the recipe or to one named ingredient. |
| Cocoa percentage | Compare the percentage on the bar you are buying. Divine lists a 70% dark bar, while M&S lists 75% and 85% dark bars; check each product's Fairtrade wording independently. | A familiar cocoa percentage helps me choose the sort of dark chocolate I prefer without treating that figure as a certification claim. |
| Hand luggage | Choose a pack you can carry conveniently and keep it accessible. GOV.UK says food in hand luggage can obstruct X-ray images and lead to a manual check; frozen items are not usually permitted. | I want a snack that fits in my cabin bag, with time allowed if security needs to inspect it. |
| Allergens | Read the current physical pack, including any precautionary warnings. M&S labels its reviewed 75% and 85% bars unsuitable for people with milk, nut or peanut allergies. | If I am buying for someone with an allergy, the word 'dark' is not enough to establish suitability. |
| Gift format | Check the pack size, filling and Fairtrade wording. Heathrow lists a 337g Guylian dark-praline box made with 72% dark chocolate and 100% Fairtrade cocoa; that cocoa claim does not, by itself, establish the scope of a Fairtrade Mark for the whole recipe. | For a gift, I may prefer a box to a single bar, provided its ingredients and the rules at my destination fit the journey. |
Common buying mistakes
-
Assuming every ethical-sourcing claim means Fairtrade certification
A brand's cocoa programme or sustainability statement does not establish the Fairtrade claim on an individual bar.
If certification is essential, inspect the exact pack for its Fairtrade Mark and check whether the claim covers certifiable ingredients across the recipe or a named ingredient.
-
Skipping the allergen label on dark chocolate
The reviewed M&S dark bars are labelled unsuitable for milk, nut and peanut allergies, while the Joybuy Guylian pralines list hazelnuts and milk ingredients.
Read the physical ingredient and allergen panel immediately before buying, especially when the chocolate is for someone else.
-
Assuming food never needs an extra security check
GOV.UK says food can obstruct hand-luggage X-ray images and prompt a manual inspection; frozen food is not usually allowed in hand luggage.
Keep a non-frozen chocolate bar accessible in your cabin bag and allow time for a possible check.
-
Applying one airport's rules to the whole trip
Heathrow says its liquid rules differ from those at many other airports, so its security process is not a guide to every departure, transfer or return journey.
Check the rules for each relevant airport and your destination before travelling with food or other items.
Brands and their Fairtrade claims
Divine
A plain-bar option: Divine describes its 70% Dark Chocolate as a 90g bar made with Fairtrade ingredients.
- Divine lists Fairtrade cocoa mass, sugar, cocoa butter and vanilla for that bar.
- Check the current pack's ingredient and allergen panel before choosing it for someone with an allergy.
M&S
M&S lists a Fairtrade 85% dark bar and a 75% dark bar described as sourced from Fairtrade cocoa farms.
- The two reviewed bars give shoppers different stated cocoa percentages to compare.
- Both reviewed bars are labelled unsuitable for milk, nut and peanut allergies; check the current pack before purchase.
Lindt
Lindt's reviewed UK range lists dark bars at 70%, 85%, 90%, 99% and 100% cocoa.
- Lindt says all its cocoa products were sourced through its Farming Program or other responsible-sourcing standards in 2025.
- That company sourcing statement does not establish a Fairtrade Mark on a particular Lindt dark bar; inspect the exact pack if that mark matters to you.
Montezuma's
Montezuma's offers dark-chocolate choices with different cocoa strengths and flavours.
- The brand says its cocoa is certified as part of its sourcing approach.
- That statement does not identify a Fairtrade Mark for an exact dark-chocolate pack; check the label if Fairtrade certification is your requirement.
Hotel Chocolat
Hotel Chocolat lists dark bars and a dark-chocolate-and-praline bar, including a filled option for gifting.
- The brand describes working directly with farmers and paying a premium for high-quality cacao as part of its own sourcing approach.
- Those practices do not establish a Fairtrade Mark on an exact bar; a praline bar also differs from plain dark chocolate.
Dark-chocolate options on Joybuy
These bars offer different cocoa percentages, flavours and pack sizes for an airport snack. Their listing claims are a starting point: check the exact pack for the Fairtrade Mark and its scope before choosing one specifically for certification.

Divine Chocolate 70% Dark Chocolate with Raspberries 90g
A 90g fruit-flavoured dark bar to consider for a cabin-bag snack. The Joybuy listing makes a Fairtrade-ingredient claim, but also describes the bar as vegan-friendly while listing milk in its ingredient and allergen information; check the physical pack for allergens and the exact Fairtrade Mark.
No image available
Tony's Dark Chocolate 180g
A 180g dark bar if you want a larger pack to carry or share. Its listing makes a Fairtrade Standards claim; check the physical pack for the mark's scope and allergen information, particularly if soya or possible traces of other allergens matter to you.
No image available
Green & Black's Dark Chocolate 85% 90g
A 90g bar for someone choosing 85% dark chocolate. Its Joybuy listing uses differing Fairtrade wording, including detail about possible mass-balance mixing, so check the exact pack's mark and claim scope; also read its precautionary almond, hazelnut and milk warning.
Questions before you travel
What should I look for on Fairtrade dark chocolate?
Look for the Fairtrade Mark on the exact pack and read its scope. The Fairtrade Foundation says the classic black-background mark means ingredients that can be Fairtrade certified are certified; the Fairtrade Sourced Ingredient mark identifies a particular Fairtrade-sourced ingredient.
Can I take dark chocolate through UK airport security?
You can pack a non-frozen chocolate bar in hand luggage, but allow for inspection. GOV.UK says food can obstruct X-ray images and prompt a manual check, and frozen food is not usually permitted in hand luggage. Check the rules for your departure airport and any onward journey.
Does buying chocolate after security settle the travel checks?
No. A post-security purchase avoids the departure security check for that item, but you should still check any airline, transfer-airport and destination requirements that apply to your journey. Heathrow also cautions that its security rules differ from those at many other airports.
How do I check allergens when buying chocolate for someone else?
Read the physical pack immediately before purchase. M&S labels its reviewed 75% and 85% dark bars unsuitable for milk, nut and peanut allergies; the reviewed Joybuy Guylian pralines list hazelnuts and milk ingredients. Do not use the word 'dark' or an older product image as an allergen check.
Do I need to declare a personal chocolate gift when travelling internationally?
HM Revenue & Customs says goods for personal use do not normally need a formal declaration when brought into or taken out of the UK. That does not determine another country's food-import rules, so check the destination authority's requirements for your gift.
