Data for UK marketplace sellers
What Temu asks for in each category, what each marketplace charges, and the VAT and product rules that apply. Every figure has a source and a date, and every dataset downloads as CSV or JSON.
Every number has a source.And the day we checked it.

02How we keep it right
Three rules for every figure here
- It comes from the organisation that sets it: the marketplace's own fee page, gov.uk, legislation.gov.uk, or Temu's own upload templates.
- We store the exact words it rests on, and a checker on our server reads every source again each week.
- If the words change, a person reviews the figure. Nothing is updated by a script on its own, and where a source says nothing we say so.
