Cracking the Code: Exporting E-commerce to the US in an Uncertain Tariff Landscape - by UKP

By UKP - The United States remains one of the most desirable markets for UK e-commerce retailers. With an online shopping population exceeding 268 million and a projected e-commerce revenue of over $1.5 trillion by 2027, the opportunity is undeniable.

For UK-based brands with a unique product offering, entering the US market often feels like the next logical step. But while the appetite is there, the journey is rarely straightforward, especially when it comes to customs clearance, logistics, and the regulatory hurdles that seem to shift faster than retailers can adapt.

The Changing Rules of Trade

In recent years, the rules of cross-border trade with the US have become more complex. The ongoing debate around tariffs, including regulatory measures and product-specific duty amendments, has introduced a layer of unpredictability for exporters. Items that once entered duty-free are now subject to elevated rates, while others face additional scrutiny under tightened trade classifications.

For example, the Section 301 tariffs, initially aimed at China, have set a precedent for rapid policy shifts that now impact other trading nations, including the UK and EU. Many UK brands shipping fashion, electronics, or lifestyle goods have been surprised to find unexpected duties applied at the point of entry, often weeks after dispatch.

Classification Risks Under HTS

Layered onto this is the challenge of ensuring that goods are correctly classified under the Harmonised Tariff Schedule (HTS). Mistakes or inconsistencies in classification can lead to delays, penalties, or overpayment of duties, all of which can erode already thin profit margins. US Customs and Border Protection (CBP) has significantly increased enforcement around mis-declared goods, particularly for higher-risk commodity codes or shipments using simplified entry methods. With more than thirty-five million international parcels processed by USPS alone every month, the margin for error continues to shrink.

Competing with US Delivery Expectations

It is not just classification and tariffs that create friction. For e-commerce brands, consumer expectations for delivery speed mirror domestic standards. American shoppers are accustomed to same-day or next-day fulfilment.

Competing in that environment from across the Atlantic requires operational finesse and a deep understanding of how to efficiently and compliantly move goods through customs. Customs clearance must be more than a final checkpoint; it needs to be embedded into the shipping strategy from the outset.

Navigating Customs Through Smarter Logistics

Retailers entering the US market are increasingly seeking solutions that offer predictability, visibility, and savings all without compromising delivery timelines. From a logistics perspective, this often means consolidating parcels for bulk customs clearance, using reliable port entry points, and leveraging trade facilitation programmes where possible. These strategies not only help navigate the fluctuating tariff environment but also reduce the administrative and financial load on growing businesses.

The Hidden Cost of Returns

There is also a growing emphasis on managing returns from the US. American consumers return 16.5% of all goods purchased online, a percentage that increases in categories such as fashion and footwear. For UK retailers, the cost of handling these returns, both logistically and from a duty reclaim perspective, can be prohibitive without the proper infrastructure in place.

With the average cross-border return costing more than 20% of the item's value, having a clearly defined reverse logistics process is no longer optional. Retailers who incorporate this into their US export model from the outset are better positioned to protect both margins and customer satisfaction.

Sustaining Growth Through Preparedness

Despite the complexities, the US remains a growth engine for UK eCommerce. In 2023, UK goods exports to the US totalled over £149 billion, with a growing proportion moving via small parcel networks driven by online sales. Cross-border eCommerce between the UK and the US alone is forecast to grow by 14% annually through 2028, underscoring the need for scalable, sustainable logistics strategies that can keep pace with consumer demand and regulatory changes. With the proper support, the rewards are substantial.

But success in the US is not just about product-market fit — it is about precision, compliance, and foresight. In a rapidly changing trade landscape, agility is the most valuable asset. Find out more here!
