Does Protein Powder Need to Be Declared at the Airport?

However, international travelers entering any foreign country must declare all agricultural items, fresh fruits, vegetables, and meats on their customs declaration card to prevent biological contamination and avoid fines up to $10,000.
How to Pack Protein Powder for a Flight
Step-by-Step Traveler Decision Checklist
- 1 Placement Decision: Cabin: YES | Checked Hold: YES
- 2 Packing & Protection: Portion scoops into small labeled jars or zip bags under 12 oz and you will skip the separate-bin step entirely. An unlabeled freezer bag of white powder is precisely what the powder screening was designed to stop. Same rule family as creatine — see the /can-i-bring/creatine page for the supplement-specific details.
- 3 Checkpoint Protocol: Keep packed securely inside carry-on luggage.
- 4 Airline & Authority Boundary: Check airline baggage policies for individual carry-on size and weight limits.
