Tesla had added another pair of high profile customers to the list of Tesla Semi pre-orders.

This time the orders come from DHL supply chain and Canadian fleet management company Fortigo Freight Services, according to Reuters.

DHL Supply Chain is a division of courier DHL Express, but instead of small-shipment freight, it handles entire supply chain logistics for companies around the world. That company has placed an order for 10 trucks to test at facilities around the U.S.

The company will be testing the trucks with same day deliveries and shuttle runs, and DHL will test them for range and efficiency on longer runs.

Ontario based Fortigo is one of the country’s larger logistics operators. That company placed an order for one truck.

Tesla isn’t saying how many orders it has received for the Semi since it was revealed earlier this month, but the list of big names who have been attached to orders continues to grow.

Retail giant Walmart has reportedly ordered 15 trucks to test in the U.S. and Canada. Freight Company J.B. Hunt has a confirmed order, and Canadian grocery company Loblaws has confirmed an order of 25.

The Semi is designed and built for North American needs, but Italian trucking form Fercam has also announced an order of a Tesla truck.

It’s a far cry from the 500,000 plus orders that the Model 3 received, but the market for this size of a truck is much smaller. There were around 284,000 sales of class 8 diesel trucks in the U.S. in 2015.

Tesla said that the Semi should offer a 500-mile range, and provide excellent acceleration for a vehicle this size. It should also offer reduced maintenance costs as well as deliver lower fuel costs. But that range is much less than a conventional truck, and a heavy battery pack could cut payload. Both big concerns for fleet operators who are focused on not just cost per mile, but getting shipments in on time.

Production of the Tesla Semi is scheduled for 2019.
