Federal rules under 49 CFR apply throughout the United States. This page covers what District of Columbia adds on top of them. It is regulatory reference only, not a Hansa Express operating footprint — see the federal overview.
In short
Federal 49 CFR applies, with DDOT administering state permits, routing and Class 1 controls.
Federal 49 CFR governs road, rail, vessel and air; PHMSA registration and an FMCSA safety permit apply to specified high-hazard loads. DDOT and MPD maintain a restrictive hazardous-material routing and permit system around sensitive federal areas. Class 1 and other high-risk loads require advance coordination, approved routes and any police escort or notification. The named primary authority is DDOT; shipment-specific permits and current operational acceptance should be verified before booking.

Regulatory reference, not a service territory
We do not provide domestic US road, rail or air transport. For eligible ocean exports, the customer delivers cargo to the agreed stuffing or port location and we manage the sea-export scope from there.
