Liquid Limits vs customs rules — what we cover

Liquid Limits vs customs rules: what this site does and doesn't cover

Liquid Limits is focused on liquids, gels, pastes, aerosols, oils, creams, liquid foods, liquid medicines, duty-free liquids, CBD/cannabis-derived liquid-like products, and dangerous liquids. Some liquid-like items also have customs, legal, or destination risks that are outside our scope.

Short answer

General guidance

Rule basis: General airport security guidance — rules can vary between airports and change over time. Confirm with your departure airport before you fly.

What to do: Pack to 100ml per container in a single 1-litre clear bag unless you've confirmed a larger allowance at both your departure airports.

Liquid Limits is a travel planning tool, not an official aviation source. Always confirm with the airport before you travel.

Airline

Can this travel in cabin or checked baggage?

Cabin OK

Most airlines defer to airport security on liquids in the cabin.

Border

Can you bring this into the destination country?

Usually OK

Liquids themselves are rarely a customs issue — but contents (alcohol, dairy, CBD) might be.

What Liquid Limits covers

Liquid Limits is an aggregator of airport security liquid-rule guidance. We cover: • Liquids, gels, pastes, and aerosols in cabin and checked baggage • Duty-free liquid rules and STEB bags • Liquid medicines and baby-food exceptions • CBD and cannabis-derived liquid-like travel risks • Dangerous liquids and substances that should never be packed • Airport-specific rules (100ml vs 2L, TSA 3-1-1, UK/EU differences)

What we don't cover

Liquid Limits is not a full customs database, immigration service, or legal advice platform. We do not cover: • Non-liquid items such as plants, meat, seeds, or fresh produce • Weapons, firearms, or ammunition • Cash, currency, or luxury-goods import rules • Electronics, batteries, or drone regulations • General immigration or visa requirements • Detailed customs value limits or tax calculations • Transit-country rules for non-liquid items

When customs or destination laws also apply

Some liquid-like items create legal or customs risk beyond airport security: • CBD oil and hemp products may be illegal at your destination or in transit • Alcohol over certain ABV limits may be restricted or taxed on arrival • Liquid medicines may need prescriptions or import permits • Food liquids like honey, olive oil, or soft cheese may breach biosecurity rules • High-proof spirits may be classed as dangerous goods When an item has a customs or legal dimension, we flag it and point you to official government or aviation sources.

How to check the rest

For non-liquid or non-security rules, use the official sources: • Destination customs / border agency website • Airline dangerous-goods and restricted-items page • National aviation authority (CAA, FAA, TSA, EASA member) • Foreign office travel advisory for your destination
