Who is the tin for?

The right format depends on whether Fairtrade status, different cocoa preferences or access to allergen information is the main concern.

Office snack organisers prioritising Fairtrade

Look for explicit Fairtrade wording or a FAIRTRADE Mark on the individual product. A brand’s broader sourcing programme does not establish the certification of every bar it makes.

Teams with different cocoa preferences

Consider a 70–75% dark option alongside a separately labelled 85% bar for colleagues who prefer a higher cocoa percentage. Do not assume one cocoa level suits the whole office.

Buyers sharing food with allergy-conscious colleagues

Keep current packaging available so people can read ingredients and allergen warnings. A vegan recipe alone does not establish suitability for someone with a milk allergy.

What should you check before buying?

Start with the Fairtrade claim on the particular product, then choose a format and cocoa level that colleagues can identify when they reach into the tin.

PriorityWhat to checkYour needs
Fairtrade status Read the current product’s mark or Fairtrade wording. The Fairtrade Foundation says its classic mark covers ingredients that can be Fairtrade certified; a Fairtrade Sourced Ingredient mark identifies a particular ingredient. I want the chocolate in the tin to meet a Fairtrade requirement, not merely carry a general responsible-sourcing claim.
Cocoa percentage Check the percentage on each bar and label different varieties separately. The cited product examples include Fairtrade bars at 70%, 75% and 85% cocoa; percentage alone does not describe every aspect of flavour. For mixed preferences, I’d put out a 70–75% option and make an 85% bar easy to distinguish for colleagues who want it.
Portion format Decide between wrapped pieces and bars broken into a tin. Divine describes its 70% Fairtrade mini-bar pack as 100 portions of 4.2g each; loose bar pieces need their original packaging kept nearby. If the tin is refilled often, individually wrapped pieces would help me keep portions identifiable. With bars, I can keep each variety separate.
Ingredients and allergens Read the current pack for ingredients and allergen or cross-contact statements. Check again when changing products or refilling: Marks & Spencer advises that its product information can change. Colleagues need to be able to identify a piece and consult its packaging before taking it. I would not treat a vegan label as a milk-allergy assurance.

Mistakes to avoid

  • Equating responsible sourcing with Fairtrade certification

    Lindt describes a cocoa programme built on Rainforest Alliance certification, while Hotel Chocolat describes its own work with farmers. Neither statement, on its own, identifies a particular dark bar as Fairtrade.

    For a Fairtrade-specific tin, check the mark or Fairtrade wording on each product rather than relying on a brand-level description.

  • Assuming vegan means suitable for a milk allergy

    A recipe described as vegan can still have a milk cross-contact warning. Lindt says its Excellence 85% bar is made to a vegan recipe but is not suitable for people with a milk allergy.

    Use the current allergen statement for the exact bar when deciding whether to share it.

  • Mixing unlabelled pieces from different bars

    Once wrappers are removed, a colleague may be unable to tell which piece matches which ingredients, cocoa percentage or allergen warning.

    Keep the original packs beside the tin and identify separate varieties, or choose individually wrapped pieces when per-piece identification matters.

Brand and product-line references

These examples show why the Fairtrade claim and allergen information need checking at product level, even when a brand is familiar.

Divine

Divine describes a pack of 100 Fairtrade 70% dark mini bars, each weighing 4.2g.

  • Individual portions offer an alternative to breaking a bar into loose pieces.
  • Check the current pack’s allergen and cross-contact information before sharing.

M&S

Marks & Spencer identifies Fairtrade dark bars at 75% and 85% cocoa, offering two labelled cocoa levels.

  • The percentages make it straightforward to identify the two varieties in a shared tin.
  • Marks & Spencer advises reading current labels because ingredients and allergen information can change.

Green & Black's

A retailer lists Green & Black's 70% organic dark bar as Fairtrade.

  • The identified 70% bar is a product-specific Fairtrade option.
  • Check the packaging for the exact cocoa-percentage variant and its current allergen warnings.

Montezuma's

Montezuma's describes its FitzRoy 74% dark bar as organic and vegan.

  • FitzRoy provides a distinct cocoa percentage for a separately identified variety.
  • Check the individual pack for Fairtrade certification before putting it in a Fairtrade-specific tin.

Lindt

Lindt offers Excellence bars at 85% and 90% cocoa and describes its cocoa programme as built on Rainforest Alliance certification.

  • The stated percentages distinguish its higher-cocoa options.
  • That sourcing description does not establish Fairtrade status for these bars; check their milk and other allergen warnings too.

Hotel Chocolat

Hotel Chocolat describes working directly with cacao farmers as part of its sourcing approach.

  • The brand explains its sourcing approach for shoppers interested in that information.
  • Check an individual dark-chocolate product for a Fairtrade claim before treating it as a Fairtrade choice.

Questions about a shared chocolate tin

How can I tell whether a dark chocolate bar is Fairtrade?

Check the current pack or product page for an explicit Fairtrade claim or mark. The Fairtrade Foundation says its classic FAIRTRADE Mark covers ingredients that can be Fairtrade certified, while a Fairtrade Sourced Ingredient mark identifies a particular ingredient; read which claim applies to the bar you are buying.

Is vegan dark chocolate suitable for a colleague with a milk allergy?

Not necessarily: a vegan recipe does not rule out milk cross-contact. Lindt says its Excellence 85% bar is made to a vegan recipe but is not suitable for someone with a milk allergy. Check the current allergen statement on every product before sharing it.

Can I put broken chocolate bars into the biscuit tin?

Yes, but keep each variety identifiable and its original packaging beside the tin. Marks & Spencer advises reading the current label because ingredient and allergen information can change; that information is harder to match to a piece once different bars are mixed together.

Should an office tin contain only 85% dark chocolate?

An 85% bar makes sense as a labelled option if colleagues want that cocoa level, rather than assuming it suits everyone. Fairtrade 70% and 75% bars provide other identifiable choices for a group with different preferences; keep each product’s packaging available for ingredient and allergen checks.
