Can I take this from one country to another?

We check three different rules in order: (1) whether airport security at your departure airport will let the item through cabin baggage; (2) whether the airline allows it in checked luggage; (3) whether the destination country lets you bring it in at the border. An item can pass step 1 and still fail step 3.

Airport security is about flight safety — liquids, sharp objects, dangerous goods. Border and customs rules are about what each country allows you to import — dairy, meat, fresh produce, CBD, medicines, alcohol allowances. They are two separate systems, run by different agencies.

Solid food is generally fine through airport security. Liquids, gels and spreads (honey, jam, yoghurt, olive oil, soft cheese, sauces) fall under the 100ml cabin-bag rule unless your airport has CT scanners that allow larger amounts. Pack the full-size jar or bottle in checked luggage.

Often no, especially flying into the UK, the US, Australia or Indonesia. Even if airport security clears it, dairy and meat are commonly restricted at the border. Check the destination's official import rules.

Usually yes if the duty-free item is in a sealed Security Tamper-Evident Bag (STEB) with the receipt visible and you don't open it. Some transfer airports re-screen liquids — keep the bag sealed and the receipt to hand.

It depends on the destination. CBD is legal in much of Europe and the UK, restricted in many places, and illegal at the border in some countries (including the UAE and Indonesia). Airport security clearing it does not make it legal to land with — always check destination law before you pack it.
