Whether you’re an ecommerce seller in Los Angeles or a manufacturer in the Bay Area, the UK remains one of America’s top trading partners, with exports from the US to the UK valued at just under $80 billion in 2024 — an increase of almost 8% from 2023.
Sharing not only a language but also similar consumer behaviors and preferences, the UK serves as both a direct market for US businesses and a strategic hub for reaching the wider European economy. And California plays a key role in US-to-UK trade, with ports in LA, Long Beach and Oakland serving as major gateways for goods moving across the Atlantic.
But shipping between the US and the UK isn’t without challenges. Ongoing labor disputes and geopolitical tensions are increasingly shaping costs and timelines, and as a US-based business, smooth transatlantic logistics mean the difference between successfully tapping into a lucrative overseas market and drowning in delays and bottlenecks.
The solution? Working with a reliable UK-based third-party logistics (3PL) provider. Whether you need order fulfillment or last-mile delivery, these 3PL companies will help US businesses navigate UK logistics with confidence.
