Asos has unveiled plans to launch a new US fulfilment centre to supercharge its rapid sales growth in the country.

The fast-fashion etailer will initially invest $40m (£31m) in its new US distribution centre, which is scheduled to commence operations next Autumn.

Development of the 10 million unit capacity facility will start shortly, with potential to expand the size of the fulfilment centre at a later date.

Asos, which posted a spike in its third-quarter sale last month, has recorded soaring sales in the US in consecutive financial results.

The pureplay retailer is rapidly expanding its international delivery capabilities, and also recently completed the first phase of development of its second European warehouse.

Chief executive Nick Beighton said: “This agreement is a major step forward for Asos in the US and demonstrates the opportunity we believe lies ahead in this key market.

“Our US business delivered 39% constant currency growth in the first six months of the current financial year following sales of £179m in the year ended August 2016.

“Our US fulfilment centre will enable us to significantly develop our proposition for our 20-something US customers supporting our continued growth and future ambitions.”
