Brexit’s impact on transport and chemical regulations were key topics of discussion this morning for Ellen Daniels, CEO of the British Compressed Gas Association (BCGA), as she spoke at gasworld’s Virtual Europe Industrial Gases Summit.

Before informing attendees on what transport regulations look like in a post-Brexit world, she recapped what such regulations currency look like. “Firstly, there’s ADR,” she said. “These are the agreements with signatories from 50 plus countries around the world which govern international transport, dangerous goods by road. This is everyone that says UK, EU and non-EU countries.”

“Then we’ve got TPED, which is the Transportable Pressure Equipment Directive, and this is a European directive that applies to the likes of manufacturer’s authorised representatives, importers, distributors, operators, so lots of different plays within the supply chain who are owners of transportable pressure equipment. And then there’s CDG, the Carriage of Dangerous Goods.” 

With reference to such regulations, Daniels explained that whilst new arrangements for UK legislation will be put in place to replace the EU requirements, existing EU directives and regulations will still apply. This period will be called the standstill period, and each directive and regulation will have their own defined standstill period, which is one or two years.

“The new UK Carriged Dangerous Goods (CDG) regulations tease apart the provisions of ADR, like we said before, that’s non-EU set of agreements, and TPED which is the EU directive” Daniels continued. “As such, the UK CDG regulations are going to incorporate equivalent methods of conformity assessment into UK law. The UK is still going to remain signed up to ADR, which is why these are going to be enshrined in the UK law through the relevant legislation.”

What does this mean?

During the standstill period, which, as I mentioned before, is a period of one or two years, depending on the directive or regulation where the EU regulations and directives are still applicable in the UK until the new legislation comes into force, Pi Marked TPE is still going to be valid in the UK and it will continue to be valid until it needs to be reassessed or reinspected up until and after the end of the standstill period.

“The UK Government has created a Rho Mark, which is going to have the same status as the Pi Mark, but it isn’t going to be recognised for TPED purposes in the EU,” Daniels explained. “TPE products placed on the UK market after a standstill will need the Rho Mark. The Rho Mark is not going to be recognised by the remaining EU 27 countries for the purposes of TPED. There are plans for Northern Ireland to have its own mark, however, this is subject to legislation which is yet to be published.”

According to Daniels, things will be very similar for static pressure equipment. She also explained that the UK now has its own set of regulations on all products that required CE Mark, and these will all now require the newly created UK CA Mark. The standstill period for this ends on the 1st of January 2022.
