Shipping to the USA gets complicated quickly
The USA is a major opportunity for UK eCommerce retailers, but the delivery journey can become complex quickly. Duties and tariffs, customs data, product classification, business structure, delivery expectations and returns all affect the experience your customer receives.
OCS helps retailers understand the practical choices, build the right delivery model and adapt when US import requirements change. The aim is not just moving parcels across the Atlantic, but to make the whole post-purchase journey easier to manage for your business and your customers.

Customs, duties and compliance
We help retailers understand the information needed for US customs clearance, including duties, tariffs and HS / HTS code requirements. Our team can also explain the practical differences between DDP and DAP / DDU approaches, helping you understand how each model affects your operation and customer experience.
Direct injection and final-mile delivery
OCS USA services use direct injection through eight US access points, helping us select routes around the requirements of the service and customer. OCS is a USPS Global Direct Entry Partner and Postal Qualified Wholesaler, and was the first international USPS Direct Entry Partner.
Tracked delivery times
For premium tracked USA services, delivery is generally expected within 3-7 days. This is a service expectation based on actual performance, not a guarantee. Customs holds, weather and other factors outside OCS control can affect international transit times.
Technology and visibility
FlightDeck gives retailers visibility across OCS operations, including tracking, service levels, exceptions, failed deliveries, returns monitoring, and customs and compliance filing and storage. OCS also supports API and eCommerce platform integrations.
Returns for US customers
The delivery experience doesn’t end at the doorstep. OCS supports retailer-branded USA returns through S.I.B.O. (Send It Back Online), using a mix of parcel shops and lockers to give customers practical return options.
Built for eCommerce retailers
OCS works with retailers selling internationally rather than individual consumer senders. Our USA experience is particularly strong in fashion and apparel: more than 90% of what OCS ships is garments.
That day-to-day experience is especially important when product classification, customs data, delivery expectations and returns all need to work together around a retailer’s customer promise.
Trusted by established retailers
USA expertise backed by experience
More than 80% of OCS shipment traffic moves to the USA, making it a central part of our international eCommerce operation. Our USPS relationship spans more than a decade, and OCS combines that network experience with people who understand the operational and regulatory detail behind cross-border retail.
Charles Tyrwhitt has worked with OCS for more than 20 years, providing a strong example of the long-term customer relationships behind the service.
“2026 will mark 21 years since OCS became an international distribution partner to Charles Tyrwhitt. OCS has supported our growth throughout that time, particularly in the US market. We’ve found OCS to be proactive concerning regulatory compliance, which helped us navigate the challenges of Brexit and is important to us in helping us navigate the complexities of changing regulations in the USA.”
