Will your medication clear customs?

Enter your medication, origin, destination, and trip length. We return a customs verdict per the destination regulator — INCB, MHLW, MOHAP, HSA, CBP, or the Schengen Article 75 framework — with the per-country quantity cap and the documents you must carry.

Rules last verified 2026-06-09. Refresh cadence: quarterly.

How verdicts are produced

Each verdict is a deterministic lookup against a versioned rules table composed from the destination country's drug regulator and the INCB country regulations index. We then apply the four-step formula: active-ingredient resolution, per-country status (prohibited, controlled, prescription-only, over-the-counter), supply-days check against your trip length, and Schengen Article 75 evaluation for intra-Schengen travel.

Active-ingredient resolution: brand names (e.g. Adderall) are mapped to their international non-proprietary name (e.g. amphetamine) before lookup.
Per-country status: prohibited, controlled (with or without pre-approval), prescription-only, or over-the-counter. Sources include MHLW (Japan), MOHAP (UAE), HSA (Singapore), and CBP (United States).
Quantity check: trip length vs. per-trip supply allowance. The US CBP 50-dosage-unit cap is applied as an override for inbound controlled substances.
Schengen Article 75 applies between Schengen members for trips up to 30 days; longer trips require the destination country's national permit route.

Advisory only — verify with the embassy

This tool provides an orientative customs verdict only. It is not legal or medical advice. Border-control practice and pharmaceutical regulation change without notice, and individual customs officers retain discretion at the point of entry. Always cross-check with the destination country's regulator or embassy before travelling, and carry the original prescription, original packaging, and a doctor's letter.
