Upgraded TikTok Shipping & Collections by TikTok Shop

Fulfillment

Summary

What is Upgraded TikTok Shipping and what benefits does it offer to sellers?

  • Upgraded TikTok Shipping is a US domestic logistics solution that centrally manages carriers, offers exclusive discounted rates (up to 30% savings), automates carrier selection, and improves fulfillment compliance with exemptions from penalties on OTDR, NRR, and VTR.
  • It provides faster claims for lost/damaged packages, enhanced complaint handling, and a reliable USPS-powered carrier network, simplifying shipping and reducing seller risks.

What is Collections by TikTok (CBT), who is eligible, and how does it differ from standard TikTok Shipping?

  • CBT is a TikTok-managed door-to-door pickup service available in select US areas (Greater LA, East Coast, Texas), offering up to 30% additional shipping discounts; sellers must have >50 daily orders and warehouses in eligible zip codes supporting CBT.
  • Unlike TikTok Shipping where sellers drop off or arrange pickups, CBT requires warehouses to sort and hold orders for TikTok pickup, and CBT couriers only handle CBT packages, ensuring better rates and convenience.

How should sellers manage shipping operations and compliance when using Upgraded TikTok Shipping and CBT?

  • Sellers must ship orders within 2 business days to qualify for OTDR exemptions; once handed over and scanned, TikTok assumes delivery responsibility, protecting sellers from delivery delays affecting performance scores.
  • CBT packages must be handed to the correct CBT courier without mixing with other shipments; incorrect handoffs or offline self-fulfillment can cause penalties and loss, requiring immediate correction and communication with warehouses.

What are the key features and setup instructions for the Package Signature Service in Upgraded TikTok Shipping?

  • The Signature Service adds $3.95 per package and automatically routes orders to carriers supporting signature confirmation (FedEx Ground, FedEx Home Delivery, USPS Ground Advantage), reducing "Delivered Not Received" claims and protecting high-value orders over $400.
  • Sellers enable this service in Seller Center per order or in bulk; it is not available via API integration and will roll out starting March 12, 2026.

How are shipping fees calculated and settled, and what tools are available for sellers to estimate costs?

  • Shipping fees are based on the greater of actual or volumetric weight (L×W×H/166), with TikTok deducting fees post-delivery from GMV or deposits; adjustments may occur after courier audits.
  • Sellers can use TikTok’s Shipping Calculator to compare TikTok Shipping and CBT rates before switching, and can customize buyer shipping fees via shipping templates in Seller Center.

Package Signature Service for Upgraded TikTok Shipping

We have officially bridged the gap for high-value and private-sensitive orders. You can now add Package Signature Confirmation to orders for Upgraded TikTok Shipping.
How it Works (New vs. Old)
Unlike the old TikTok Shipping model where you manually select a carrier and then add a signature, the upgraded TikTok Shipping prioritizes efficiency:
  1. Automated Selection: You simply enable the "Signature Service" value-add in Seller Center.
  2. Smart Routing: Our system automatically verifies carrier support. If your current shipping service doesn't support signatures, the system automatically switches your label to an eligible FedEx or USPS service, no manual action required.
The Details
  • Launch Date: We are gradually rolling out starting March 12, 2026.
  • Cost: $3.95 per package (automatically deducted) if you choose to enable this service.
  • Supported Channels: FedEx Ground, FedEx Home Delivery, and USPS Ground Advantage.
  • Benefit: Drastically reduces "Delivered Not Received" (DNR) claims and protects high-value inventory (especially orders over $400).
  • Availability: Seller Center only. (Note: Signature services are currently unavailable for API-integrated shipping.)
How to Setup
  1. Single Order Setup
After a shopper places an order successfully, go to Manage Orders, select the order to request a shipping label. On the Arrange Shipment sub-page, check Signature Required to enable the signature service for this package.

  1. Bulk Order Setup
Select multiple orders in Manage Orders to request shipping labels in bulk. On the Arrange Shipment page, go to Value Added Services, edit the signature service and check Signature Required to enable it for the selected packages.

Frequently Asked Questions (FAQ)

Service Subscription

  1. CBT vs. TikTok Shipping— What’s the difference?
    • TikTok Shipping serves everywhere: TikTok Shop sorts orders, then you drop off or third-party courier gets picked up.
    • CBT is a door-to-door pick-up service only in the Greater Los Angeles Area, East Coast and Texas. Warehouses need to sort orders, hold them separately, and wait for TikTok Shop to collect them. Plus, you’ll get better rates.
For more details, please refer to TikTok Shipping & CBT Operating Procedure.
  1. I’m currently using Seller Shipping. Can I switch to the upgraded TikTok Shipping?
    • Yes! If your ERP provider has integrated with the upgraded TikTok Shipping system, you can follow the steps outlined in How to Upgrade your TikTok Shipping Account section to make the switch.
If you’d like to join the CBT service, please refer to the TikTok Shipping Activation Guide. Our team will help enable access for you.
  1. Can I use TikTok Shipping for cross-border warehouses?
    • Not yet. TikTok Shipping is currently only for US domestic warehouses.
  2. If I have two warehouses, one using CBT and the other using TikTok Shipping, how are the shipping and settlement prices determined?
TikTok Shop will automatically determine the shipping warehouse based on inventory availability. The warehouse with available stock will be prioritized. If both warehouses have inventory, TikTok Shop will choose the one closest to the customer.
  • If the order ships from the CBT warehouse, the CBT rate will apply.
  • If it ships from the TikTok Shipping warehouse, the TikTok Shipping rate will be used for settlement.
    1. What happens if I have inventory for the same product in both FBT and my own warehouses?
    Answer:
    For the same SKU, the system will determine the shipping path based on the following logic:
    • If there is inventory in the FBT warehouse, the order will be fulfilled from FBT by default
    • If the FBT warehouse is out of stock, the order will be fulfilled from the seller’s own third-party warehouse
    • If multiple warehouses have inventory, the system will prioritize the warehouse closest to the customer for shipping.
      Please note: If an order contains two products: one stored in an FBT warehouse and the other in a TikTok Shipping warehouse, the order will automatically be split and shipped separately.
      Example:A shop sells Product A, which is enrolled in FBT. Meanwhile, the shop also has the following three warehouses:
      • Warehouse A: Located in Los Angeles, enrolled in CBT
      • Warehouse B: Located in New Jersey, enrolled in TikTok Shipping
      • Warehouse C: Located in Texas, using TikTok Shipping
        Product A is linked to all three warehouses. When a customer places an order, the system follows this shipping logic:
        • If inventory is available in the FBT warehouse, the order will be shipped directly from FBT.
        • If FBT has no inventory, and all three warehouses have stock, the system will automatically choose the warehouse closest to the customer and match it with the appropriate shipping service:
          • Shipping from Texas → TikTok Shipping order
          • Shipping from Los Angeles → CBT order
          • Shipping from New Jersey → TikTok Shipping order
        1. Priority to FBT warehouse shipping
          • If FBT is out of stock, ship based on proximity
            • If only one warehouse has inventory
            • Regardless of the customer’s location, the system will ship from the only warehouse with stock and automatically apply the corresponding shipping method.
            1. My ERP is self-developed or not listed, what should I do?

            Shipping

            1. Where do I print my TikTok Shipping labels?
            Go to Seller Center → Order Management → Arrange Shipment
            1. Do I still need to follow the shipping rules after using TikTok Shipping?
            Yes, you are still required to ship the order within 2 business days to avoid impacting your LDR. If the package is not shipped on time, it will not be eligible for OTDR exemption.
            Once the package is handed over and the pick-up scan is recorded, TikTok Shipping will take over responsibility for the rest of the logistics process. If the package is not delivered within 6 business days, it will not affect the seller’s OTDR score.
            For detailed shipping and fulfillment rules, please refer to the Guide to On-Time Delivery Rate (OTDR)
            For non-CBT orders, if there is no pick-up scan after handing the package over to the logistics provider, please contact your local logistics service provider to resolve the issue.
            1. How do I ship after joining TikTok Shipping?
            Keep doing what you’re doing!
            If you currently use the carrier’s pickup, keep using it.
            If you drop off at the carrier’s site, keep doing that too!
            1. Can I mix CBT packages with others when handing them to USPS or other couriers?
            No, CBT packages must go to the CBT courier. Mixing them up can cause tracking issues, and these orders will not be covered by TikTok's service protection.
            1. Why do I need to give the package to the right carrier?
            Our shipping service uses different carriers like FedEx, USPS and others, which can sometimes cause confusion about which carrier to hand the package to. It’s important to give the package to the carrier shown on the label so it gets delivered on time.
            If you give it to the wrong carrier, the package could be delayed, lost, or you might get extra fees. Always double check the label before handing it over.
            1. Can CBT couriers pick up non-CBT packages?
            No, CBT couriers only handle CBT orders.They won’t process other packages. Errors will not be covered by TikTok's service protection.
            1. What should I do if the warehouse says the CBT carrier didn’t come to pick up the goods, or if there’s no tracking record after pickup?
            Pickup delays can occur for various reasons. CBT carriers will arrive on time as scheduled after confirming the pickup time and frequency with the warehouse. If a delay occurs, please follow the steps below to verify and handle the issue:
            1. Confirm the order type:
              Confirm whether the order is a CBT order. The logistics carrier for CBT orders will be displayed as "CBT" rather than any other carrier. Only CBT orders are eligible for scheduled pick-up service.
              1. Confirm the Warehouse Shipping Status
                There may be a time gap between when the seller clicks “Ship” in the system and when the warehouse actually completes packing and outbound processing. Please first check with the warehouse to confirm whether the operational instruction has been issued and if all items have been packed and shipped. Supporting documentation such as outbound records or photos of packed goods can help verify this.
                1. Contact the Pick-Up Staff
                  If the warehouse confirms that all goods have been dispatched but there is still a delay in pick-up, please reach out to the designated pick-up staff using the contact information provided below.

                                    Billing

                                    1. How are shipping fees settled?
                                    TikTok deducts shipping fees from either your GMV or deposit. Billing happens after successful delivery & transaction completion. Sometimes you might see a second charge adjustment after the courier’s actual weight audit.
                                      1. Can I set my own buyer shipping fee?
                                      Yes, you can set up customized shipping fee templates in the system.
                                      1. How are shipping fees calculated based on order weight and dimensions?
                                      Shipping fees for TikTok Shipping (include CBT) are calculated based on the greater of the product’s volumetric weight (also known as dimensional weight) and actual weight, as maintained by the seller. Sellers are required to ensure that product dimensions and weight are accurate.
                                      How to calculate volumetric weight: Length(inch) x Width(inch) x Height(inch) and divide by 166
                                      When shipping via Seller Center, the estimated shipping fee shown during label creation is calculated using the product dimensions and weight maintained in Seller Center.
                                      When shipping via an ERP system, the estimated shipping fee is calculated based on the product dimensions and weight maintained in the ERP.
                                      After the parcel is handed over, the logistics service provider will measure the actual weight and dimensions of the shipment and may adjust the shipping fee accordingly. The platform reserves the right to recalculate and adjust the final shipping charges based on the verified actual weight and dimensions of the shipped items.
                                      For example: You have a package that is 16” x 12” x 10” and weighs 5 lbs. The volumetric weight: 16*12*10/166 ≈ 12 lbs. Since the volumetric weight (12lbs) is heavier than the actual weight (5lbs), the shipping fee will be calculated based on volumetric weight (12lbs).

                                        1. How to get live agent support through the assistant window?
                                        When entering the virtual assistant, please provide a brief description of your issue.
                                        • Do not simply type “create a ticket” or “live agent,” as the assistant will still need to ask for your specific problem
                                        • Recommended format: [Issue] + [Need agent support]
                                        • Example: “I've already got my packages ready, but no one has come to pick them up. Can you help check with the provider? I need an agent's help right now”
                                          ▶ After reviewing the virtual assistant’s response, you may confirm if you still need live agent support. If so, simply click “Chat with live agent”
