Before ordering from iHerb to Guam, review the delivery method, possible import charges, and carrier contacts. Promocodes may reduce the order price under current conditions.
This guide summarizes the official iHerb shipping information for Guam. The information was checked in 2026. Shipping, customs, tax, carrier, and delivery terms may change, so verify the current conditions with iHerb and the relevant Guam customs authority before placing an order.
Shipping overview for Guam
iHerb orders for Guam are shipped from iHerb’s U.S. warehouses by air freight. The delivery window shown at checkout reflects most standard deliveries, but it is not a guarantee. Air freight delays, customs holds, and other complications outside iHerb’s control can extend transit time.
Important delivery warning: The estimated delivery window may be extended by air freight delays, customs clearance, or unforeseen events. Plan accordingly rather than treating the displayed window as a guaranteed arrival date.
Carriers and shipping-related support
The official shipping reference identifies UPS Express and DHL Express support contacts for shipping-related questions:
- UPS Express: (671) 649-2877.
- DHL Express: 646-1765.
For questions not covered by the shipping reference, use iHerb customer service. The official iHerb shipping information is also available for review.
Customs, taxes, and additional fees
Orders to Guam may be subject to import taxes, customs duties, or a brokerage or handling fee. These charges are separate from the shipping fee and may be billed directly by the carrier selected for delivery.
Because exchange rates can fluctuate, an order whose value is very close to the applicable tax-free limit may still be assessed duties and taxes. The exchange rate used on the order date may differ from the rate used when the shipment reaches customs.
Important customs warning: Do not assume that an order near a tax-free threshold will remain exempt. Exchange-rate changes between purchase and customs clearance may affect the assessment of duties and taxes.
Before importing products, check with Guam’s local customs office to confirm that the items are permitted and whether any additional licenses or permits are required.
What to check before placing an order
- Review the current shipping options and delivery information shown by iHerb for your Guam address.
- Check with the relevant Guam customs office about product eligibility, permits, licenses, and possible import requirements.
- Allow for possible air freight or customs delays beyond the displayed estimated delivery window.
- Budget separately for possible duties, taxes, and carrier brokerage or handling charges.
- Keep order and delivery details available in case iHerb or the carrier requests information.
