But the moment we leave the EU, this stops. Your component manufacturer may still comply with exactly the same standards, but the testing houses and the regulatory agencies are no longer recognised. The consignment has no valid paperwork. And, without it, it must be subject to border checks, visual inspection and physical testing.
What that means in practice is that the customs inspector detains your shipment and takes samples to send to an approved testing house (one for the inspector, one for the office pool, one for the stevedores and one for the lab is often the case). Your container inspection is typically about £700 and detention costs about £80 a day for the ten days or so it will take to get your results back. Add the testing fee and you’re paying an extra £2,000 to deliver a container into the EU.
Apart from the costs, the delays are highly damaging. Many European industries have highly integrated supply chains, relying on components shipped from multiple countries right across Europe, working to a “just in time” regime. If even a small number of consignments are delayed, the whole system starts to snarl up.
