Short answer: on TikTok Shop UK, a creator has 14 days from delivery to post a video that stays live for at least 3 days, or to host a LIVE that makes at least one sale. If they don't, the sample is marked as failed and their sample fulfilment rating drops. You can't get the sample back, so the fix is upstream: approve creators with a strong posting record, confirm the plan before you ship, send a one-page brief, follow up before day 14, and stop sampling creators who didn't post last time.
You approved the requests, paid for the product and the postage, and the parcels were delivered. Then nothing. If that sounds familiar, you're not alone: “30 samples, zero sales” is one of the most common stories from new TikTok Shop sellers. The good news is that most of it comes down to a handful of fixable decisions.
What TikTok Shop UK's rules say
From TikTok Shop's UK seller and creator guides (Samples: Seller's Guide, Free Sample Guide for Creators):
| Rule | What it means for you |
|---|---|
| Creators must post within 14 days of delivery | Day 14 after the parcel arrives is your real deadline, not the day you ship. |
| Fulfilment = a short video kept live for at least 3 days, or a LIVE that makes at least 1 sale | A video deleted after a day doesn't count. |
| No content → the sample is marked failed | Statuses in Seller Centre: Pending Content, Post Failed, Completed. |
| Failed samples lower the creator's sample fulfilment rating (Ok, Good, Better) | That rating is visible to you before you approve anyone. Use it. |
| You must review requests within 7 days and ship approved samples within 7 days | Otherwise they're cancelled automatically. |
| One sample per product per creator; in open collaboration a creator can have up to 5 sample requests in progress | Creators juggle several brands at once, so yours competes for their time. |
| Requirements pause if your product goes out of stock, under review or inactive | Keep the product live and in stock while samples are out. |
TikTok Shop sends creators automated reminders, but the guides don't describe any refund or charge when a creator doesn't post. The cost of a failed sample is yours.
Why samples don't turn into videos
- You're approving “sample collectors”. Some creators request far more samples than they ever post about. Their fulfilment rating tells you, but it's easy to approve on follower count alone, which says very little about who posts or sells.
- The creator doesn't fit the category. A lifestyle creator who has never sold skincare has no reason to start with your serum, and their audience may not buy it.
- Nobody agreed what the video would be. Without a brief, the product sits in a pile with four other brands' samples.
- There's no follow-up. A friendly nudge a few days after delivery is often the difference between posting and forgetting.
- The offer is weak. If your commission is below what similar products pay, or the product is hard to show on camera, it drops to the bottom of the list.
How to fix it, step by step
- Approve on posting record, not followers. In Sample Requests and Find Creators, check the creator's sample fulfilment rating and use the “From reliable creators” filter (TikTok's top 20% by posted content per sample received). Then check that they've sold in your category recently, their average video views, and whether their audience's age and gender match your buyers.
- Set thresholds and a cap on open collaboration. You can require minimum followers, average views, 30-day sales and an estimated post rate before creators can request, and cap the number of samples. Treat samples as a test budget: decide how many you'll send before you stop and review.
- Confirm before you ship. Message the creator first and ask what they'd make and roughly when. A clear, specific reply is a good sign; no reply or a vague one is a reason not to ship.
- Send a one-page brief by message and in the parcel: the one problem the product solves, three opening-line ideas, key ingredients or features in plain English, anything they mustn't claim, and the call to action (tap the basket, the current offer).
- Follow up on a schedule. Nudge 3–5 days after delivery, remind around day 10–11 (before the 14-day deadline), and thank creators as soon as they post. Offer the ones who sell a better commission.
- Track every batch as a funnel. For each batch, count samples approved → delivered → posted → views → orders. The first step where numbers fall off tells you what to fix: few posts means creator selection; posts with few views means the angle or opening; views with no orders means your listing, price or reviews.
- Stop re-sampling no-shows, and double down on sellers. Don't approve another sample for someone who didn't post the last one. Invite the creators who did sell to a targeted collaboration with a higher commission.
What “good” looks like
TikTok Shop doesn't publish a cut-off for a good fulfilment rating. In its UK Free Sample Approval Strategy, case studies from individual sellers give a sense of the bar. These are those sellers' own benchmarks, not platform rules:
- A womenswear seller only works with creators whose sample fulfilment rate is 80% or higher (most of their partners are above 90%) and approves about 20% of sample requests.
- A fitness equipment seller approves about 15–20% of requests, favouring creators with a sales record, an audience mostly over 24, high fulfilment and steady engagement.
In other words: experienced sellers turn down most sample requests. Approving everything is the fastest way to run out of samples.

FAQ
How long do creators have to post a TikTok Shop sample in the UK?
14 days from delivery. They need to post a short video that stays live for at least 3 days, or host a LIVE that makes at least one sale.
What happens if a creator doesn't post?
The sample is marked as failed and the creator's sample fulfilment rating goes down, which makes it harder for them to get samples in future. TikTok Shop's UK guides don't describe any refund to the seller.
What's a good sample fulfilment rate?
There's no official threshold. Sellers in TikTok Shop's UK case studies look for 80% or more, and check the creator's sales in their category as well.
Should I approve every sample request?
No. Experienced sellers in TikTok Shop's case studies approve about 15–20% of requests. Approve on posting record and category fit, and confirm the plan before shipping.
Can I automate the follow-ups?
TikTok Shop sends creators its own automated reminders. Your own messages, such as the brief or a personal nudge, go from the Affiliate Centre, either one by one or through a tool that sends them on a schedule.
