Small in scale but steady in purpose, Portsmouth on New Hampshire's Piscataqua River is a working bulk and breakbulk harbour rather than a container port. Operated by the New Hampshire Port Authority, its Market Street Terminal handles general and dry-bulk cargo, supported by bulk docks, a petroleum distribution facility and a state fish pier. Typical commodities include imported road salt, gypsum, scrap metal and petroleum products, while a Foreign Trade Zone allows duty-deferred storage and processing. No container liner services call here, and the roughly 9.4 m tidal channel with its strong Piscataqua currents limits vessel size. For containerised freight, the Port of Boston (Conley Terminal) and facilities at Portland, Maine are the nearest alternatives. Forwarders mainly use Portsmouth for regional salt and building-material imports and selected breakbulk lots.
