A bill moving through the UK Parliament would give ministers the power to order transport and logistics operators to remove technology supplied by vendors assessed as a national security risk. If your European orders pass through a UK warehouse, carrier or customs broker, that is a decision about your order flow that somebody else gets to make.

The power is targeted rather than general. It applies to transport and logistics operators, and it covers technology bought from a vendor the government judges to be a national security risk. Warehouse management systems, telematics, scanning hardware, port and terminal software all sit inside that description. A supplier that looks acceptable when you sign your fulfilment contract may not look acceptable two years later.

What the bill does not yet tell you is how long an operator would get to comply, what happens if it misses, or how a vendor gets designated in the first place. Reporting on the Lords stage sits behind a paywall and that detail is not on the public record. Treat the direction as settled and the mechanics as open.

For a US brand the exposure is indirect, which is what makes it easy to miss. You do not own these systems. You depend on them. If a UK provider is ordered to strip out its warehouse management platform, your stock sits still while the replacement is configured, order statuses stop reaching your storefront, and your marketplace despatch metrics take the damage. None of that shows up on your own technology roadmap.

One question is worth putting to your UK provider now. Which vendors sit in the critical path between an order landing and a parcel leaving, and what is the fallback if one of them has to be replaced at short notice? Providers who can answer that in writing are the ones who have already thought about it.

• Ask your UK fulfilment provider and carriers to name the vendors in the critical path between order capture and despatch.
• Check whether your contract obliges the provider to give notice of a forced system change, and how much notice that is.
• Hold a second route into the UK and EU so one provider's migration cannot stop your order flow.
• Keep your product, stock and order data exportable, so changing provider does not mean rebuilding your catalogue.

Expandly's UK and EU fulfilment runs through its own warehouse network rather than a chain of subcontractors, which keeps the list of systems in your critical path short.
