Fulfilled by TikTok, and What It Changes
TikTok holding your stock buys the same things Amazon's warehouse buys: a badge, a delivery promise, and one less thing to run. It costs the same things too.

What Fulfilled by TikTok Does, in TikTok's Words
TikTok Shop's US shipping requirements, dated 16 September 2026, list three ways to ship an order: Seller Shipping, which "may only be available to select sellers"; TikTok Shipping, on a carrier TikTok lists; and Fulfilled by TikTok, where "TikTok warehouses handle the storing, picking, packing, and shipping of orders." The first two keep the seller on the clocks in TikTok Shop's fulfilment rules for orders you ship yourself.
Speed. TikTok's FBT page, dated 6 August 2026, says orders ship "within 24 hours" from hubs on both coasts and 14 fulfilment centres, and that 80% arrive within three days.
The tag. Eligible products carry a "Free 3-Day Delivery" tag, and the FBT rate card has made every FBT product free to ship by default since 16 June 2025, with no $30 minimum.
Cover. Late dispatches, cancellations, negative reviews and returns that are not the buyer's fault, where logistics caused them, "are excluded from seller performance metrics".
TikTok's own data for June 2025 puts the tag's worth at a 15% to 20% higher conversion rate for the same product: the platform's figure for its own feature, which the honest test further down lets you check on yours.
The Stock Commitment Nobody Plans For
What TikTok Charges for It
Fulfilment. TikTok's US rate card, dated 27 October 2026 and changed several times this year, charges one fee per unit for "pick, pack, packaging, and last-mile shipping to the shopper", set by weight and deducted on delivery. Its own worked example is $4.70 for a single 9 oz shirt, and two or more units from the same seller in one checkout pay less each. Since 1 May 2026, items up to 2 lb and 332 cubic inches are charged on actual weight, larger ones on dimensional weight where that is higher.
Storage. The first 60 days are free. After that, from 15 December 2025, TikTok charges per cubic foot per day: $0.03 to day 90, $0.04 to day 120, $0.06 to day 180, $0.12 to day 270, $0.14 to day 365 and $0.27 beyond, on sellable and defective units alike.
Inbound and returns. An East or West hub costs a placement fee; shipping straight to the fulfilment centres costs none if TikTok's routing is followed, and routing mistakes cost from $0.50 a unit. Since 1 June 2026, returns are charged per unit, replacing a flat $3.00 an order.
In our reading, that table is why the first commitment above should be sized to sell within 60 days: from day 181, storage costs four times the day 61 rate.
What It Costs Against Shipping Yourself
Joining, and Getting Stock In
None of TikTok's US FBT pages we read sets a sales or account-age threshold: its FBT page sends a seller to Seller Center, then Fulfilled by TikTok, to "Join the Waitlist" or "Get Started". From there the seller adds barcodes and expiry dates to products already in the FBT portal, creates an inbound shipment, and books a delivery appointment for pallets or enters tracking for parcels.
The FBT Product Packaging Requirements, dated 5 February 2026, are where first shipments go wrong. Packaging. No foam peanuts or shredded paper, and a bundle needs one barcode of its own and the labels "Sold as a Set" and "Do Not Open". Shelf life. Dated products must arrive with their usage period plus 90 days left: 90 days for snacks, 270 for beverages, 365 for skincare and supplements. Batch codes. Consumables and some beauty products, sunscreen among them, need one on every unit, one batch per carton. Failing stock "may be rejected, returned, destroyed, or delayed during receiving".
Limits. Since 13 July 2026, FBT takes units up to 150 lb, with no side over 108 inches. A shared inventory feature, dated 23 June 2026, lets up to five TikTok shops draw on one FBT pool.
The Shipping Standards, and What FBT Takes Off Them
How to Decide
What to Read After the First Month
The first commitment is an experiment, so decide before it ships what would count as success, and read four numbers once a month of sales is in.
Sell-through against the free window. Units sold in the month against units received. At that pace, will the rest sell before day 60, when storage starts to be charged? If not, the next shipment is smaller or later, however good the best day looked.
Conversion against your own shipping. The product's conversion on FBT against the weeks before, or against a comparable product you still ship yourself. It is the honest test from earlier, and the only evidence that the tag is worth its fee on your catalogue rather than on TikTok's average.
What receiving did. Units received against units sent, and any rejected or delayed for packaging, shelf life or batch codes. A shortfall there is a packing fault to fix before the next carton, not a cost of the channel.
Returns per unit. FBT charges for each returned unit, so a product that comes back often costs more than its fulfilment fee suggests, and its price has to carry that before the second shipment is sized.
The second commitment is then sized from those four numbers rather than from the video that went furthest.
What It Does Not Fix
Where This Goes Next
The comparison most sellers are really making is with Amazon, and using Amazon to fulfil orders you did not sell on Amazon is the other way to keep one stock pool. Where fulfilment sits in the whole account, and what else has to be true before an order exists, is in how to sell on TikTok Shop, and what moves units.
