iHerb Hong Kong Guide (2026): Shipping, Promo Codes and Best Sellers

iHerb Hong Kong guide 2026: free shipping, same-day delivery, promo codes and best sellers

Quick answer: To shop iHerb in Hong Kong, use hk.iherb.com so prices show in HKD. Shipping is free on orders over HK$150 (a limited-time offer at the time of writing), and if you order before 11am you can get same-day delivery by JD Express. New customers can use the code NEW20 for 20% off the first order.

Why Hong Kong Shoppers Use iHerb

iHerb was founded in the United States in 1996 and now ships to more than 180 countries. What makes it different for Hong Kong is that it runs a logistics centre here, alongside its warehouses in the US, South Korea and Saudi Arabia. That is why many orders now arrive the same or next day, instead of the two-week wait people remember from a few years ago.

It is also one of the easiest ways to buy American supplement brands that are hard to find in local pharmacies, from California Gold Nutrition to Doctor’s Best and Swanson. All prices and shipping rules below were checked on hk.iherb.com in November 2026.

Shipping to Hong Kong: Your Options

  • JD Express Same Day Home Delivery: order before 11am HKT for delivery between 3pm and 10pm. Not available for outlying islands such as Cheung Chau, Lantau, Peng Chau and Lamma
  • Home delivery: SF Express or JD Express. With Global Air Home Delivery, iHerb picks the faster, cheaper carrier for you
  • SF lockers and stores: free storage for 24 hours at lockers and 48 hours at pickup stores, then SF charges HK$15 a day
  • Climate Controlled Home Delivery: delivered in a 17 to 22°C vehicle, useful for probiotics in summer
  • Free shipping: orders over HK$150, marked as limited time, so check the banner before you pay

Payment Methods

iHerb lists Visa, Mastercard, American Express, UnionPay, PayPal, Apple Pay, Google Pay and AlipayHK among its payment options. The exact list depends on your device and account, so check at checkout.

How iHerb Promo Codes Work

  • NEW20: 20% off a new customer’s first order, one use only, applied before shipping
  • D11MEGA: 26% off sitewide for the 11.11 sale, valid until 12 November 2026
  • Subscribe & Save: iHerb offers 10% or more off your first subscription order and 10% off repeat deliveries on many products, if you buy the same item every month

A promo code is not the same as a referral or “rewards” code (three letters and a few numbers, like ABC123). Use only one code per order and check the final price in the cart.

FAQ

Is iHerb legit and are the products authentic?
iHerb is a long-established retailer that buys from brands and ships from its own logistics centres, including one in Hong Kong. Buying from hk.iherb.com directly avoids the risk of third-party resellers.

Do I pay tax on supplements shipped to Hong Kong?
Hong Kong generally does not charge import duty on supplements for personal use. Some items are restricted, so check the Customs and Excise Department if you are unsure.

How do returns work?
According to iHerb’s help centre, you can request a refund within 30 days for most products and within 90 days for iHerb brand products, counted from the day you receive them. Start the request in your account before sending anything back.

Can I buy Swanson directly from its own website?
Not for delivery to Hong Kong. Swanson’s site says international orders are handled by iHerb, so buy Swanson on hk.iherb.com.
