If you import or export any goods using WPM (pallets etc) or supply WPM to businesses, you need to follow the rules to meet ISPM15 international standards from 1 January 2021. This is so you can move them between Great Britain (GB) - England, Scotland and Wales - and other countries, including EU member states and Switzerland. 

The WPM rules from 1 January 2021 for traders operating in Northern Ireland are different. If you move WPM (for supply or to move goods) from Northern Ireland to the EU, there will be no changes to WPM requirements. These movements will continue as before. If you use WPM to supply qualifying Northern Ireland goods from Northern Ireland to Great Britain there will be no changes to WPM requirements. These movements will also continue as before. WPM used to transport non-qualifying Northern Ireland goods must be treated and appropriately marked in compliance with international standards (ISPM15). If you move WPM (for supply or to move goods) from Great Britain to Northern Ireland, your WPM must be treated and appropriately marked in compliance with international standards (ISPM15). Checks will be carried out on a risk-targeted basis only, taking into account that GB to NI movements are very low risk. 

WPM includes: 

● Packing cases 
● Boxes 
● Crates 
● Drums and similar containers 
● Pallets, box pallets, pallet collars and other load boards
