TikTok Shop will recommend combining orders placed by the same shopper across different order channels within a predefined time window, provided that the shopper, delivery address, seller, and seller warehouse are the same. By consolidating these orders into a single package, this cross-channel order combination can encourage repeat purchases while reducing shipping costs.
Importantly, TikTok Shop will display reduced shipping fees to shoppers during checkout for subsequent purchases with the same seller (within a specific time horizon), thereby incentivizing incremental orders, repeat buying, and growing GMV.
There will be 3 opt-in options for sellers:

• Offer free shipping on subsequent orders： Eligible shopper orders placed across supported order channels within the applicable time window will be considered together when shipping fees are calculated. Shoppers receive free shipping on eligible orders placed after the first order. A countdown banner will appear on the order confirmation page to encourage additional purchases within the eligible time window. During fulfillment, Seller Center will recommend combining eligible orders into a single package.
• Offer reduced shipping fee for eligible orders: Eligible shopper orders placed across supported order channels will be considered together when shipping fees are calculated, and shoppers will only be charged the incremental shipping fee for additional eligible orders. When the seller fulfills the orders, Seller Center will provide a package combination recommendation.
• Do not offer: No combined-shipping discount will be applied when the shopper’s shipping fee is calculated. However, eligible orders may still receive a package combination recommendation when the seller creates shipping labels, and the seller can choose whether to combine them.

Why use Saved Shipping Fee by Combining Orders?

Saved Shipping Fee by Combining Orders helps sellers encourage shoppers to place additional orders while reducing the cost and complexity of fulfilling multiple orders separately. Key benefits include:

• Drive repeat purchases: Free or discounted shipping on later orders gives shoppers an additional incentive to buy more.
• Improve conversion during LIVE: Sellers can promote shipping savings during a livestream to encourage shoppers to place follow-up orders.
• Reduce fulfillment costs: Eligible orders can be packed into one parcel and shipped with one label instead of multiple separate shipments.
• Simplify fulfillment: Fewer packages, labels, and fulfillment actions can improve warehouse efficiency.
• Balance sales growth and shipping costs: Sellers can choose whether to provide free shipping, charge only the incremental combined shipping fee, or charge full shipping for every order.

How to enable this feature?

To enable Combined Shipping:

1. Navigate to Seller Center > Logistics > Fulfillment > Saved Shipping Fee by Combining orders.

2. Click the corresponding button to customize the settings as needed, then click "Save" to apply the changes.

Capped Shipping Fee for LIVE Rooms Orders

Feature Availability: Capped Shipping Fee for LIVE Rooms Orders is currently being rolled out in phases. Some sellers may not see this feature yet. It will be available to all eligible sellers starting September 10, 2026 (PT).

What is the Capped Shipping Fee

The Capped Shipping Fee for LIVE feature allows sellers to set the maximum total shipping fee a shopper can be charged during a single LIVE session. This gives shoppers a clear expectation of their shipping costs and encourages them to continue purchasing within the same LIVE session.
Once the feature is enabled, the capped shipping fee applies to all eligible orders placed by the same shopper during the same LIVE session, as long as the LIVE session is still ongoing. The setting applies to all LIVE sessions in the shop, but the shipping fee cap is calculated separately for each LIVE session.
Once the shopper’s accumulated shipping fees reach the configured cap, no additional eligible shipping fees will be charged to the shopper for the remainder of that LIVE session. Any eligible shipping costs above the cap will be covered by the seller.

How Is the Capped Shipping Fee Calculated?

Suppose a seller sets the shipping fee cap for a single LIVE session at $6.
A shopper places multiple orders during the same LIVE session:

• Order 1 shipping fee: $3
• Order 2 shipping fee: $3
• Total shipping fees charged: $6

At this point, the shopper has reached the $6 shipping fee cap for that LIVE session. If the shopper continues purchasing eligible items, even if a new order would normally incur a $3 shipping fee, the shopper’s total shipping fees for that LIVE session will still not exceed $6.
Any eligible shipping costs above the cap will be covered by the seller.

How to Enable Capped Shipping Fee

1. In Seller Center, go to Logistics > Fulfillment.
2. Open Saved Shipping Fee by Combining orders.
3. Select Offer reduced shipping fee for all eligible combined orders.
4. Set up Capped shipping fee for LIVE orders and set your shipping fee cap
5. Enter the maximum shipping fee that a shopper can be charged during each LIVE session. Once the cap is reached, you will cover any remaining shipping costs for eligible orders.
6. Click Save.

LIVE Room Shipping Fee Rates for Sellers

A flat seller shipping rate applies to eligible packages weighing between 1 and 5 lbs, whether orders are shipped individually or combined. These special rates apply to packages created from orders placed during a LIVE session and are based on TikTok Shop’s seller shipping rate card. They are separate from the shipping fees charged to shoppers at checkout. The applicable seller rate varies by shipping service, such as TikTok Shipping – Standard Delivery or Collection by TikTok (CBT). Click TikTok Shipping LIVE Flat Rate to learn more.

Logistics fulfillment

Combined orders shipping

For orders placed under Offer free shipping on subsequent orders or Offer reduced shipping fee for eligible orders, eligible orders may be combined into a single shipment.
When you select Combine and Continue and proceed to the Arrange Shipment flow, TikTok Shop checks whether the selected orders are eligible to be combined. If they meet the combination requirements, an Auto-combined tag will be displayed to indicate that the orders can be fulfilled together.

Review combined shipment:

After you complete the shipment arrangement for the combined orders, the orders will display a Combined shipment tag on the Order Management page. This tag indicates that the orders have been arranged and fulfilled as a combined shipment.

• Video Example: How to Combine Orders into One Shipment

Order combination by shipping options

• TikTok Shipping and CBT

Orders are not combined automatically. During the order Awaiting shipment process, Seller Center may recommend combining eligible orders based on criteria such as:

• The same shopper
• The same delivery address
• The same shipping warehouse
• Other applicable combination requirements

Sellers can review and either accept or reject the recommendation. If accepted, the eligible orders will be combined into one package, allowing the seller to purchase and print a single shipping label.

• Seller Shipping

Auto-combined orders can be combined with regular orders. Sellers can also update the tracking number after the orders are combined, subject to the applicable order-status requirements.

• Fulfillment by TikTok (FBT)

Eligible orders are automatically combined for delivery. No action is required from the seller.

• Global Shipping – Direct Shipping

Order combination is not available for sellers using GS Direct Shipping.

Split an auto-combined shipment

Before the orders move to Awaiting Collection, sellers can adjust the combined shipment:

1. Click View combined packages.
2. Select the orders you want to remove from the combined shipment.
3. Click Save.
4. After the changes are saved, the combined order list will display only the orders that remain in the package.

Note: Auto-combined shipment information cannot be edited once the order status changes to Awaiting Collection.

API Sellers

Reference document for API-based order combination shipment integration details here.
API sellers who have enabled the feature:

• If multiple orders have the same auto_combine_group_id, it means that these orders can be combined for shipping.
• Sellers who have not enabled the feature:

Notes for weight rules

• When packages are combined, shipping fees increase with weight tiers (actual / dimensional weight). Adding a lightweight item within 1 lb may only slightly raise costs, but crossing into the next weight tier can result in a significant fee jump.
• Example 1: Actual Weight
  • One item weighs 0.5 lb. Adding another 0.5 lb item, a total of 1.0 lb (still within 1 lb) — cost increase is minimal or zero.
  • Adding three 0.5 lb items (total 1.5 lb) exceeds the 1 lb threshold and triggers a higher rate in the next tier.
• Example 2: Dimensional Weight
  • One item measures 10×10×10 inches, actual weight 0.5 lb. If a shopper purchases two, total volume becomes 20×10×10 = 2000 cubic inches (>1728), so rates apply to dimensional weight. Even though actual weight is 1 lb, dimensional weight is 12 lb, leading to a sharp rise in shipping cost.
• Our Recommendations: Consider actual and dimensional weight when enabling auto-combine. You may simulate shipping costs using the calculator on the logistics service page before activation.
• Clearly explain shipping fee calculation to shoppers during live streams to avoid unexpected high costs at checkout.

Set custom Order Combination Rules

To better support different order consolidation scenarios—especially orders generated during LIVE sessions—and, and help reduce logistics costs, sellers can customize Order Combination Rules for package combination recommendations.
Order Combination Rules apply when you select “Offer reduced shipping fee for eligible orders” under “Save shipping fee by combining orders.” Once enabled, your customized rules will be applied during shopper checkout to determine which orders are eligible for combined shipping.
You can configure rules based on multiple dimensions, including:

• LIVE sessions
• Product categories
• Package weight
• Package dimensions
• Number of items per package

Relationship Between Save Shipping Fee by Combining Orders and Order Combination Rules:

• Save Shipping Fee by Combining Orders determines how shoppers are charged for shipping when they place multiple eligible orders within a specified time window.
• Order Combination Rules determine which orders are eligible to be combined during fulfillment based on conditions such as LIVE session, product category, package weight, package dimensions, and item quantity.

When a seller selects Offer reduced shipping fee for eligible orders, the configured Order Combination Rules are also applied during checkout. Based on these rules, shoppers may be charged an incremental shipping fee for additional eligible orders. To learn more, see Order Combination Rules.

FAQ

Does enabling the feature guarantee that every additional order will receive a lower shipping fee?

No. The shipping benefit depends on the selected option and whether the orders meet the applicable combination requirements.
For the combined shipping fee option, the discount is based on the difference between the shipping cost before and after the orders are combined. Package weight, dimensional weight, delivery distance, and the selected shipping service may affect the final shipping fee.

Why were the shopper’s orders not combined?

What is the maximum weight for a combined package?

The current overall combined-package limit is 150 lb, but the actual limit may be lower depending on the selected shipping service. Sellers should review the applicable carrier requirements and configure Order Combination Rules accordingly.

Why does the second order’s shipping fee still appear high after combination?

Possible reasons include:

• The combined package may enter a higher actual-weight tier;
• The combined dimensions may trigger dimensional-weight pricing;
• The product weight or dimensions entered by the seller may be higher than the actual values.

Sellers can use the shipping calculator under Logistics → Shipping to estimate the cost of typical combined packages before enabling the feature.

How can I confirm that orders were successfully combined?

Go to Manage Orders and review the package information. Successfully combined orders will display a Combined Shipment label and will be associated with the same combined package.

When should I start fulfilling orders placed during a livestream?

To maximize the opportunity to combine orders and reduce fulfillment costs, sellers are encouraged to begin fulfillment after the livestream ends.
For continuous or 24-hour livestreams, sellers may process and fulfill orders every six hours.

Can orders from different warehouses be combined?

No. Orders assigned to different warehouses cannot be combined into the same package. Sellers should ensure that products promoted together during a livestream are fulfilled from the same warehouse when possible.

Can I remove an order from a recommended combination?

Yes. Before the combined package reaches the applicable shipping stage, sellers can review the recommended combination and remove orders that they prefer to fulfill separately. Additional shipping costs caused by separating previously combined orders may be borne by the seller.

Why did the shopper pay more shipping than expected after order combination? How can I identify the cause?

What is a capped shipping fee for LIVE?

A capped shipping fee sets the maximum total shipping fee a shopper can be charged during a single LIVE session. Before the cap is reached, normal shipping fees apply. Once the cap is reached, no additional eligible shipping fees are charged to the shopper, and the seller covers the remaining eligible shipping costs.
The cap is calculated separately for each shopper and each LIVE session.

Do orders need to be shipped from the same warehouse or combined into one package?

No. Eligible orders can count toward the shipping fee cap even if they are shipped from different warehouses or in separate packages.
However, shipping orders separately may increase the seller’s fulfillment costs. Sellers are encouraged to combine eligible orders whenever possible.

Does a capped shipping fee mean shoppers always pay a fixed shipping fee?

No. Shoppers pay the applicable shipping fees until the cap is reached. After that, no additional eligible shipping fees are charged during the same LIVE session.

Does the shipping fee cap reset for a new LIVE session?

Yes. The cap is calculated separately for each LIVE session and does not carry over from a previous LIVE session.

What costs does the seller cover after the cap is reached?

The seller covers any additional eligible shipping costs that are no longer charged to the shopper after the cap is reached. Actual fulfillment costs may vary depending on package count, weight, shipping method, and whether orders are combined.

How should API sellers fulfill orders with a capped shipping fee?

API sellers should use the auto-combine ID to identify orders that can be combined and combine eligible orders whenever possible. Shipping orders separately will not affect the shopper’s capped shipping fee benefit, but it may increase the seller’s fulfillment costs.
