Since July 1, 2021, in accordance with new EU regulations, iHerb collects VAT on most orders to France at the time of purchase. This simplifies the customs clearance process and generally avoids additional fees upon delivery. For orders exceeding certain values (usually €150), additional customs duties may apply and be collected by the carrier upon delivery. iHerb clearly indicates the amount of VAT collected on your invoice, and the prices displayed on the site already include applicable VAT.

iHerb accepts a wide range of payment options to facilitate your international purchases. These include major credit and debit cards (Visa, Mastercard, American Express), PayPal, Apple Pay, Google Pay, and many local payment options like Bancontact, iDEAL, and Sofort for European customers. All payments are processed via secure connections with SSL encryption to protect your financial information. iHerb also offers real-time currency conversion, allowing you to view and pay in your local currency (EUR for France).

Once your order is shipped, iHerb sends you a confirmation email containing a tracking number and a link to the carrier's website. You can also track your order at any time by logging into your iHerb account and accessing the "My Orders" section. For international shipments, multiple carriers may be involved in the delivery process (e.g., DHL then La Poste for France), and the tracking number generally works for the entire journey. If you encounter difficulties tracking your package, iHerb's customer service is available 24/7 and can provide updated information on the status of your delivery.

iHerb offers a 90-day satisfaction guarantee on most products. If you are not satisfied with your purchase for any reason, you can return the product within 90 days of the purchase date for a refund or exchange. For international orders, iHerb refunds up to €20 of return shipping fees for defective or incorrect products. To initiate a return, log into your account, access the relevant order, and follow the return instructions. Note that certain items such as perishable foods, hygiene-sealed products that have been opened, or special promotion items may not be eligible for returns.

iHerb reward credits are automatically accumulated in your account with each eligible purchase, at a rate that depends on your loyalty level (Silver, Gold, or Platinum). These credits can be applied to your future purchases during the checkout process. To use your credits, simply select them as a partial or full payment method during checkout. iHerb reward credits are valid for a period of 90 days from the date they were issued. You can view your current credit balance and expiration date in the "Rewards" section of your account.
