The border is real now
Since 1 January 2021, Great Britain and the EU are separate customs and VAT territories. There is no automatic free circulation in either direction: goods moving GB→EU are exports from GB and imports into the EU, and goods moving EU→GB are the reverse. That single fact drives the whole stock-location decision — wherever your stock sits, the other region's orders cross a customs border, with the VAT, declarations and delivery-time cost that comes with it.
The rules-of-origin trap
The UK–EU trade agreement allows zero tariffs — but only on goods that meet rules of origin, meaning they genuinely originate in the UK or EU. Goods made elsewhere (say, manufactured in Asia) and simply warehoused in the UK do not automatically qualify just because they passed through a UK warehouse. Re-exporting non-originating goods across the GB–EU border can attract the other side's import tariffs unless the goods were sufficiently processed to change their origin.
This catches brands who assume "it's in our UK warehouse, so it's basically European". It isn't. Rules of origin are product-specific and depend on where things are actually made, so check your own products' position rather than assuming — it's one of the biggest hidden costs in a UK-only stock model that serves EU customers.
Three models, honestly compared
UK-only stock. Simplest to run, fast to UK customers, one compliance regime. But every EU order crosses the border, with EU import VAT and possible duty per parcel. Best when the UK is your dominant market and EU sales are a minor tail.
EU-only stock. The mirror image — fast to the EU, but every UK order is an import into the UK. Rarely the right base for a brand whose growth market is the UK.
Dual stock (UK + EU). UK stock serves UK customers same-territory; EU stock serves the EU same-territory; neither everyday order crosses a border. This is the model most scaling brands land on. The honest cost: two inventory pools to forecast, two compliance regimes, and enough volume in each region to justify a second node. Below a certain EU volume, a single UK hub shipping cross-border is simply cheaper.
VAT on low-value parcels, both sides
Each side has a low-value mechanism. The EU's Import One-Stop Shop (IOSS) lets sellers collect EU import VAT at checkout on consignments of €150 or less, rather than at the border — though non-EU businesses generally need an EU-established intermediary to use it. The UK has its own point-of-sale VAT rule for consignments of £135 or less.
The bigger planning point: the era of duty-free low-value parcels is ending on both sides. From 1 July 2026 the EU applies an interim customs duty (€3 per tariff classification) to parcels of €150 or less that were previously duty-free, pending fuller reform expected around 2028. In parallel, the UK is removing its £135 customs duty relief "by October 2028 at the latest". Whichever side you hold stock, factor in that low-value parcels get more expensive to move across the border from here — verify the current rules for your lanes, as both reforms are still moving.
Frequently Asked Questions
Should I hold stock in the UK or the EU?
It depends on where your customers are and your volumes. UK-only stock is simplest and fast to UK customers but adds a border to every EU order; dual UK+EU stock removes that friction for each region but doubles the operational and compliance load. Most brands start with a single hub in their dominant market and add a second node once the other region's volume justifies it.
Can I ship to the EU from a UK warehouse?
Yes, but it is a cross-border export from GB and an import into the EU, with EU import VAT and potentially customs duty per parcel. Crucially, goods that don't originate in the UK or EU may not qualify for zero tariffs under the trade agreement's rules of origin just because they sat in a UK warehouse — so check your products' origin position before assuming EU orders ship duty-free.
What is IOSS and do I need it?
The Import One-Stop Shop is the EU scheme that lets sellers collect EU import VAT at checkout on consignments of €150 or less, instead of at the border. It smooths EU delivery for low-value orders, but non-EU businesses generally need an EU-established intermediary to register. Whether it's worth it depends on your EU order volume and values.
Are low-value parcel rules changing in the UK and EU?
Yes, on both sides. From 1 July 2026 the EU charges an interim customs duty (€3 per tariff classification) on parcels of €150 or less that used to be duty-free, with fuller reform expected around 2028. The UK is removing its own £135 low-value customs duty relief by October 2028 at the latest. Both are still developing, so confirm the current rules for your routes.
