Industries in Washington, D.C. and how we support them
The Washington region is home to federal government agencies, many defence and aerospace contractors and one of the largest data centre concentrations in the world in Loudoun County. These organisations ship electronics, server and network equipment, defence and space components and sensitive documents, often subject to US export controls. We support them with air freight under our own air waybills via IAD and BWI, Next Flight Out for urgent equipment, On-Board Courier for sensitive items, and sea freight through the Port of Baltimore. For export-controlled goods we check the documentation and licence references with you before shipping.

Frequently asked questions
Who handles customs clearance for imports into the Washington region?
Clearance is done by a partner team in the Ziem network under the Ziem Logistics brand, to our procedures and with the shipment data we prepare. Entries are filed with U.S. Customs and Border Protection (CBP) through ACE, and you deal only with Ziem Logistics.
What export controls apply to defence and aerospace goods from Washington?
Defence articles are controlled under the International Traffic in Arms Regulations (ITAR), administered by the State Department, while dual-use items fall under the Export Administration Regulations (EAR). The exporter determines the classification and obtains licences; we file the Electronic Export Information (EEI) with the correct references.
Can goods for government projects be imported duty-free?
Some can, under specific provisions, but this depends on the goods, the end user and the contract. Duty-free entry is not automatic. We recommend clarifying the applicable provisions with your contracting authority and providing the documents to us before shipping.
