International Travel

Air security rules, customs and what to check vs. carry on.

Quick summary

1. Packaging

Biggest mistake: putting everything in daily "pill organizers". Always keep original bottles with legible labels. For compounded products, make sure the pharmacy label has your name and clear composition — helps a lot if questioned at customs.

2. Powders in carry-on

Most international agencies (TSA in the USA, ANAC in Brazil, EU in general) inspect powder containers >350ml (~12oz, size of a soda can) in carry-on baggage.

3. Liquids and gels — 3-1-1 rule

Adopted in almost all airports worldwide (TSA/USA, ECAC/Europe, ANAC/Brazil, UK, Asia):

4. Shopping abroad — where and what

5. Importing to Brazil (on return)

6. Pro traveler tip
