I don't remember how strict Immigration is there(as opposed to Suvarnabhumi, where they won't let you bring even 100 ml. of any liquid - or less!) on board. I want to bring about 50 ml of coconut oil and some vitamin gel caps. Don't want to have either confiscated. Even if it means checking my carry-on(which I could do on-line for 350 baht). What are the odds of getting the stuff removed?

I travel through DM monthly with similar amounts of medication in hand luggage and in 3-4 years have never been questioned.

Keep the coconut oil in it's original container in a clear plastic bag.

They might get fussy over the gel capsules, could contain any substance.

Never had a problem bringing a small bottle of liquid at the immigration so I think that's fine.

I don't know about the coconut oil. However, the gel capsules shouldn't be an issue. Justget a written note from a physician stating that the gel capsules are vitamin supplements. Put the gel capsules in a baggie with the note from the doctor.
