In some sources it is written that you can carry bath salts:

Bath bombs are also allowed, but call them ‘bath salts’ in the airport, to avoid any misunderstandings at security!

But there are opposite articles:

Returning from Nantes to Edinburgh yesterday on Ryanair, my 200g canister of sea salts for a foot bath was confiscated. I knew there was a 100 ml limit on liquids, obviously, but I can't find any information on the Ryanair site which mentions any restrictions on non-liquid toiletries.

The guy said I should have decanted the salts into two 100 ml bottles. I offered to decant them into two plastic bags, but he said it was the size of the container that counted, not the contents.

Do you have any experience with bath salts / magnesium flakes in hand luggage flying within Europe? If it is allowed, what's the limit for hand luggage?

    The airline doesn't screen your hand luggage, the local airport security or government transit security organization does. Which airports are you flying to and from? Dec 16, 2018 at 20:22

  • At least in the US, "bath salts" is a common street name for a group of synthetic drugs of abuse, so I would not necessarily use that term with law enforcement either...

The 'LAG' restrictions enforced throughout much of the world cover Liquids, Aerosols, and Gels. Whilst the definition of these can be a little vague (is Peanut Butter really a Gel?), dried "salts" fairly clearly do not fit into any of these categories.

I have traveled with bath salts > 100ml/100grams in my carry-on bags in the past and have never had a problem. On one occasion the airport security staff did ask to see them as they were not able to determine from the X-ray what they were, but once they confirmed what they were then I was let through without any issues.

The US TSA "Can I Bring" website doesn't have a specific entry for Bath Salts (which is a good sign, as if they were disallowed it most likely would), but does have "salt" which is allowed with no size/volume restrictions.

Just as a warning, be aware that "bath salts" is also the street name for an illegal class of Synthetic cathinone drugs. They have this name because they have a crystalline form that resembles normal bath salts.

  • My baggage was inspected by TSA at SFO (cabin) and in JFK (checked, they have left inspection note wrapped around salt bottle). Jul 11, 2019 at 7:03

There was no problem with 1kg magnesium flakes for cabin baggage. Security staff didn't know about the restrictions.
