The Imports headline is the import side of US International Trade in Goods and Services (the joint monthly trade report, acronym FT-900). It covers goods on a balance of payments basis plus services imports, all seasonally adjusted. Goods are compiled from Customs documents with low value estimates, while services are survey estimates.
Coverage spans physical goods arrivals across the US Customs Territory for government and nongovernment shipments. It measures General Imports, not only Imports for Consumption cleared through Customs. It excludes transit goods under bond, military shipments, monetary gold, carrier fuel, and returned repairs. Import values exclude US duties, and headline gains widen the deficit when exports hold steady.
