Sample requests do not sit in your queue indefinitely. There is a clock on them, and a second clock starts the moment you say yes.

You have seven days to review a free sample request on TikTok Shop. If you have not approved or declined it by then, the system cancels the request automatically. Approving starts a second seven-day window, this time to ship the product from Seller Center.

The request is cancelled by the system, not by you. The creator is not told you were too busy, they just see a request that expired.

There is a cost beyond the lost sample. A creator whose request expires has to wait 30 days before they can apply for that product again. The same 30-day wait applies to a request you actively disapprove. A creator who withdraws their own request can reapply immediately.

So an expired request is not a neutral outcome. It removes a creator who wanted your product from your funnel for a month, and it is the one outcome where nobody made a decision.

Approving is not the end of the timeline. Three more deadlines follow.

Seven days to ship. Once you approve, you have another seven days to get the product out from Seller Center.

Fourteen days for the creator to post. Free sample creators are required to post content within 14 days of receiving the product.

One seven-day extension. Creators who cannot make the 14-day deadline can request a single extension from the sample order details page, which gives them seven more days.

The seven-day review window applies to free samples, the ones you approve individually. Refundable samples do not need seller approval at all, so there is no review clock for you to miss. Eligible creators buy the product and get refunded once their content meets the criteria, and they have 90 days to meet it before the order becomes a regular purchase.

If your review queue is the bottleneck, refundable samples remove you from the critical path entirely.

The seven-day window is generous until volume arrives. Once outreach is working, requests come in faster than anyone wants to review them by hand, and the ones that expire are rarely the ones you would have declined. They are just the ones nobody got to.

Two things help. Review on a fixed schedule rather than when you remember, so no request ages past a few days. And hand the routine decisions to the AI Auto-Approval Agent, which applies your criteria (minimum follower count, past creator-attributed GMV, niche fit) automatically and leaves you only the judgment calls.

The Sample Manager shows every open request in one place so you can see what is aging before the system decides for you.
