The rule: PRIIPs and the KID
Since 1 January 2018, EU law (the PRIIPs Regulation) requires that any “packaged” investment product sold to EU retail investors comes with a standardised Key Information Document (KID) — a short, prescribed disclosure of risks, costs and scenarios in the local language.
US ETF providers produce US disclosures, not an EU-format KID. Without a KID, an EU broker isn't allowed to sell the product to a retail client. So the broker blocks the buy order. (You can usually still sell or hold an existing position.)
Who it affects
- EU/EEA retail investors — blocked from buying US-listed ETFs at most brokers.
- UK retail investors — the UK retained equivalent rules post-Brexit, so the same block largely applies.
- Professional/elective-professional clients — may still access US ETFs if they qualify and opt up.
- Some non-EU jurisdictions — rules vary; many investors elsewhere also default to UCITS for the tax reasons.
What to do instead
The fix is simple: buy the UCITS equivalent, which comes with a proper KID and is built for you anyway. For most popular US ETFs there's a UCITS fund tracking the same index — see UCITS equivalents of popular US ETFs, or match any ticker with the US ETF → UCITS finder.
And as covered in UCITS vs US ETFs, for a non-US investor the UCITS version is usually the better choice regardless — lower US dividend withholding and no US estate-tax exposure.
