With potential customs checks between the UK and the EU, there may be delays at the border.
Your business should consider
The potential of customs checks to cause delays at the border will depend on how new policies are implemented in practice: customs checks are typically risk-based rather than universal. As yet there no details on how enforcement might be executed in practice.
How resilient is your supply chain to potential border delays?
Do any contracts you have include penalties for late delivery? You may want to discuss with your logistics provider whether you would require new arrangements.
Do you need to increase your inventory and/or buy additional storage space?
