The unpredictability involved in doing business with the US has come into sharper relief with the threat of new tariffs being applied to UK exports. And international delivery specialist ParcelHero said Britain’s small businesses “will be the first casualties of [President] Trump’s new Greenland tariff war”.

Any new tariffs come after extra duties were already imposed last year while the de minimis exemption was abolished.

In 2024, the UK exported around $828m-worth of textiles such as clothing to the US. Most of these products will have had a value of under $800 and that de minimis abolition will have had a huge impact. 

But even those business selling luxury goods that didn’t previously qualify for zero duties under the de minimis rule have been hit hard already. 

ParcelHero said that the UK currently has one of the most favourable US tariff rates of 10%, following a trade deal with the country, but “even so, a UK-made coat costing $800 is already likely to cost US shoppers at least an extra $80 (£60) more than it did at the beginning of 2025, assuming that the UK seller passed on all the tariff costs to their US customers. That may not be the only applicable tariff, however, as it could also attract a further tax depending on the item’s tariff code.”

With the new tariff threat just issued, from the beginning of February, “that same coat could cost American consumers around $960 due to the imposition of a further 10% tariff. More concerningly still, from June it could cost them more than $1,000, as February’s 10% tariff rises to 25%. UK specialist and family-run businesses will struggle to survive in the US market as American shoppers turn to cheaper products from elsewhere”.

Parcelhero thinks Trump’s tariff threat over Greenland will particularly impact small UK businesses — which are less able to absorb extra costs and to have the mega-marketing budgets to cement their desirability in consumers’ minds — disproportionately.

The company’s head of consumer research, David Jinks, said he “agrees with UK Prime Minister Keir Starmer that the imposition of new tariffs on the UK and seven other countries that oppose Trump’s plans to take control of Greenland is ‘completely wrong’.

“Many smaller UK exporters are already reeling from the impact of the 10% tariff imposed on the majority of UK products last year. On top of that came the axing of the US de minimis tariff exemption that previously enabled British goods valued at $800 (around £600) or under to enter America duty free. Britain’s SME manufacturers and exporters are likely to be the first casualties of Trump’s new tariff war. Many smaller UK companies may have to quit the US market entirely if the Greenland tariffs are imposed.

“The US is Britain’s largest single overseas market and in 2024, before Trump announced his ‘Liberation Day’ tariffs in April 2025, around 39,500 UK VAT-registered businesses exported goods to the US. Many of these are SME businesses and marketplace traders that are disproportionately affected by the new tariffs.”

And the company thinks that if the tariffs are applied, it will mean a wider move towards tariffs globally. “Whatever the ongoing impact of new US tariffs, the repeal of its de minimis rules and a potential tit-for-tat trade war over Greenland, we are inevitably looking at a period of continuing volatility and changes to US shipments,” Jinks added.
