Airport Liquid Rules 2026: Check the Actual Checkpoint
Check the current airport procedure, EU container limits, Heathrow scanners and duty-free transit. Separate screening from checked-baggage allowances.
Scanner equipment and liquid-volume permission are different questions. Check each airport’s current instructions for your terminal, departure, any transit screening and return. A country label or scanner rollout date does not certify every checkpoint.
What is actually established for these examples
| Scope | Volume/presentation |
|---|---|
| General European Commission guidance for EU departures | Ordinary containers up to 100ml, one transparent resealable bag up to 1 litre |
| Current Heathrow departure instructions | Containers up to 2 litres each; liquids and large electronics stay in the bag |
| US FAA personal-toiletry transport exception | Separate aggregate/container limits; its footnote also states TSA screening limits containers to 100ml |
Heathrow says to empty metal and insulated bottles before its checkpoint. Another UK or international airport may have different equipment and instructions. Check Gatwick, Manchester, Edinburgh and any other airport individually; scanner presence is not a worldwide exemption. Follow the signs and staff if asked to present items separately.
Check the container and the actual product
A half-empty 200ml container does not comply with a 100ml capacity rule. Toothpaste, cosmetic creams, gels, pastes, aerosols and similar mixtures count as liquids in the cited EU guidance. Dry-shampoo spray is not the same as dry powder. A genuinely solid stick differs from a gel or cream; it is not automatically free from every transport restriction.
Use the general liquid packing guide for a practical table and bag test. A scanner cannot make prohibited chemicals acceptable. US FAA qualifying personal medicinal/toiletry articles have a combined 2kg/2-litre limit per person and 0.5kg/500ml per container, with protected aerosol nozzles. Cabin security, carrier conditions and customs remain separate.
Plan exceptions and onward screening
General EU guidance permits essential medicines and baby food/milk above 100ml when needed during the trip; proof and screening may be required. Do not treat that as unlimited medicine, guaranteed acceptance of supplements or permission to import a particular drug. For US medical and infant exceptions, use TSA’s current instructions for your checkpoint rather than extending the EU example.
For EU duty-free handling, keep item and receipt sealed in the security bag until the final destination. Staff may open it to screen; explain a further connection so it can be resealed in a new bag. The cited Your Europe text covers purchases from any airport or airline under those conditions, so a blanket claim that non-EU origins or all non-Schengen transfers are refused is unsupported. Confirm your full route before buying; an intact seal does not promise worldwide acceptance.
Use a route checklist
Before departure, record the applicable airport instructions, check ordinary container capacity and actual closed-bag fit, identify necessary exceptions and carry identifying information, retain the duty-free receipt/seal and protect against leaks. Avoid assuming 30ml bottles always fit, a shampoo bar lasts as many as three bottles, hotel products are provided or shops will replace a surrendered item. Airport instructions and actual packaging resolve the practical decision.
