Founded in 1996, iHerb carries tens of thousands of products and ships to many countries. It can ship directly to Taiwan, but freight can be higher for small orders. This guide explains discount codes, Brand Rewards, personal-use TFDA rules, and practical savings tactics.

Why Use iHerb?
- Large catalog: supplements, natural foods, personal care, and beauty products
- Transparent unit pricing: many products show per-serving cost
- Authenticity control: iHerb sells through its own platform rather than open third-party marketplace listings
- Direct Taiwan shipping: available for many products with 5 to 10 day delivery windows
- Chinese interface and Taiwan payment support: easier than many U.S. supplement stores
- Price gap: often 30% to 50% below Taiwan pharmacy or retail pricing
Discount-code System Explained
Four iHerb Discount Types
Summary: iHerb discounts can stack in some cases, and strong promotion periods can save 25% to 30% or more.
Four Discount Types
- New-customer first-order discount: usually a fixed amount or percentage for the first order
- Referral code: the buyer receives a discount and the referrer receives credit
- Brand Rewards: credits earned from eligible purchases for later use
- Subscribe savings: recurring products can receive an extra discount on scheduled orders
Stacking Examples
- New customer: new-customer offer + referral code + Brand Rewards credit can create strong first-order savings
- Promotion season: Brand Rewards + Subscribe + limited-time brand promotions can make larger replenishment orders worthwhile
- Daily or weekly spotlight: selected brands may receive deeper short-term discounts
Some products or brands do not accept discount codes or Brand Rewards. Always verify the final discount in the cart before checkout.
Direct Shipping vs. Consolidation
| Item | iHerb Direct to Taiwan | U.S. Consolidation Warehouse |
|---|---|---|
| Freight | Convenient but can be high for small orders | Lower when combined with other U.S. purchases |
| Delivery time | About 5-10 days | About 10-15 days depending on route |
| Customs | iHerb often handles much of the process | Handled through the consolidation service |
| Free-shipping threshold | Depends on current iHerb campaign | No store free-shipping threshold, but warehouse freight applies |
| Returns | iHerb customer service | Return must go through warehouse handling |
| Combining orders | Not ideal | Can combine iHerb with Amazon, Costco, GNC, and other U.S. goods |
| Bulk buying | Single-order freight can add up | Bulk and multi-store orders can spread cost |
When Should You Ship Directly or Consolidate?
- Direct shipping: one or two items, first-time trial orders, urgent orders, or when iHerb direct freight is discounted
- Consolidation: five or more items, repeat household replenishment, USD$300+ multi-store orders, or combining with Amazon U.S. and Costco products

Five Money-saving Tips
1. Combine Subscribe savings with Brand Rewards
Recurring products can receive extra savings, and Brand Rewards credits can reduce future orders. Cancel or adjust subscriptions before the next billing cycle if needed.
2. Use iHerb promotion windows
Weekly spotlight brands, end-of-season sales, Black Friday, and iHerb anniversary promotions can produce the deepest discounts.
3. Consolidate to hit efficient freight thresholds
Combine enough items to spread freight cost, but keep quantities within personal-use and customs-safe ranges.
4. Use referral codes properly
New buyers can use a referral code, then receive their own code for later referrals. Confirm the discount appears before payment.
5. Buy larger bottle sizes when consumption is steady
NOW Foods 250-count bottles or 5 lb protein tubs usually have lower per-serving cost than small sizes. Do not overbuy products with short shelf life.
Seven iHerb Consolidation Steps
1List your supplement needs
Write down monthly-use supplements, estimate a reasonable six-month household quantity, and set a budget before shopping.
2Choose iHerb and apply discounts
Use iHerb.com, apply a valid referral or new-customer code, and confirm Brand Rewards or subscription discounts.
3Choose direct shipping or consolidation
Use direct shipping for small trial orders. Use consolidation for larger multi-item purchases, repeat orders, or combined Amazon U.S. purchases.
4Use the Oregon warehouse for consolidation
Ship U.S. orders to the Oregon warehouse and combine with Amazon U.S., Costco, GNC, or other items where appropriate.
5Inspect after warehouse arrival
Confirm product names, quantities, and expiration dates. Check again for TFDA-restricted ingredients such as hormones or CBD.
6Complete EZWay declaration
Declare as supplements or food with accurate value and personal-use quantity. See the supplement import guide for details.
7Clear customs and deliver
Duty can vary by classification, and 5% business tax may apply. Food and supplement inspection risk depends on ingredient and quantity.
