iHerb Japan Customs & Shipping Guide (免税と配送)

Ordering from iHerb to Japan (Tokyo, Osaka, Kyoto) comes with specific rules you must follow to avoid customs duties and delays. Our guide for 2026 ensures your supplements arrive without hassle.

• The 16,666 JPY Rule (免税限度額): This is the most crucial detail. Ensure your order subtotal is under 16,666 JPY (approximately $110 USD). Orders above this limit will incur Japanese consumption tax and customs duties. Using code BCU0786 helps keep your order below this threshold.
• Melatonin Import Restriction (メラトニン): Be extremely careful with Melatonin. Japanese regulations only permit a maximum of 2 bottles of Melatonin per order. Exceeding this will result in your package being seized.
• Weight Limits: For smooth delivery, keep your order weight under 10kg (22 lbs).
