Can you give a link to an EU or other official document showing the EU - not, for example, May's Chequers proposal - banned these in April?

My words were I wonder why the EU insisted on scrapping them in April?

The EU words were: European Parliament resolution of 26March 2019 on financial crimes, tax evasion and tax avoidance (2018/212
Calls on the Commission to bring forward a proposal for the urgent phasing out of the system of free ports in the EU.
