Full details
The US allows travelers to bring personal insulin supplies with a valid prescription. TSA permits insulin, syringes, and pump supplies through security with notification. Insulin does not need to be in the 3-1-1 liquids bag. Keep medication and devices together for easy inspection. In the reverse direction (taking insulin out of United States): allowed — Insulin may be exported from United States freely for personal use with prescription documentation; the practical constraints are cold-chain and needles.
Leaving United States with insulin
Insulin is not a controlled substance and personal-use quantities may be taken out of United States without export formality. Carry the prescription or pharmacy label and a doctor's letter covering needles and injection devices — the letter is what security screening and destination customs ask for. Keep insulin in cabin baggage (hold temperatures can freeze it) with a cool pack; aviation liquid limits exempt medically necessary liquids. Quantities beyond a personal trip supply may draw questioning about resale.
No special procedure is required for personal quantities of insulin arriving in United States. Quantities above duty-free allowances must still be declared. Verify current limits with U.S. Customs and Border Protection (CBP).
