✂️ Beard trimmer

Nothing — electric beard trimmers are permitted in both carry-on and checked baggage everywhere, and screeners will not flag them. The blades on a beard trimmer are small and guards-protected, which is why they are not treated as a prohibited sharp item. Your trimmer will pass through the X-ray without any issue.

Beard trimmers are unrestricted worldwide in both carry-on and checked baggage — no country applies a special rule to them. The only consistent rule that could affect your trimmer is the global prohibition on spare lithium batteries in checked baggage, which applies if your trimmer uses a removable lithium cell. The trimmer itself has no restrictions anywhere.

A trimmer with a charging cable and multiple attachments can create a complex X-ray image, which occasionally prompts a bag check. The check is about identifying the image clearly, not because the trimmer is restricted. Keeping your trimmer and its accessories organized in a small pouch helps screeners identify it quickly and keeps your bag moving.

Either works from a security standpoint. Carry-on is the safer choice if your trimmer has a built-in lithium battery, since you want to avoid it being gate-checked and ending up in the hold — where loose lithium batteries in checked bags are prohibited. If the trimmer uses removable batteries, take them out and keep the batteries in your carry-on if you check the trimmer itself.
