Corona Virus Changes

In an effort to provide for the needs of our customers, as well as employees, HDI Marine will remain open.

HD International is considered an essential business by the Federal Government as we supply the electric utility industry and public works, thus allowing our continued operation.

For the safety of our employees and the public we have made two simple yet effective changes that were implemented March 14, 2020:

One employee is allowed in each of our two facilities per day on a rotating schedule; these employees are using sanitation protocols while in the facility. All other employees work from home.

All shipments are to be picked up at our locations, so that none of our employees will be transferring shipments or entering Post Office or FedEx facilities.

All international shipments ordered with USPS shipping will be shipped Fedex due to USPS COVID-19 Service Impacts

Your business and time is important to us and we will do our best to ship in a timely manner.

Please understand given the protocols our pick-up times for delivery are as following:


Fed Ex Ground ~ 4PM PST

Safe boating,
