Customs district and port breakdown
Customs district and port breakdowns are sub-national geographic dimensions that attribute US trade flows to the place where goods cleared Customs. USA Trade Online exposes U.S. state, Customs district and port breakdowns beside worldwide partner-country detail as slicing dimensions, with monthly data from January 2002.
What is Customs district and port breakdown?
US trade statistics can be attributed geographically two ways: by trading partner, or by where inside the United States the goods moved. The cataloged example is USA Trade Online (US Census Bureau), whose coverage field reads "United States as reporter, with partner-country detail worldwide; U.S. state, Customs district and port breakdowns" - and which carries the tags 'state-trade' and 'port-data'.
These dimensions are selectable per dataset. Users pick HS-district, port, state, imports or exports variants - plus NAICS-based state and district datasets - then combine commodity codes to six-digit HS, partner countries and a time selection spanning monthly data from January 2002 and annual data from 1992. Reports render in-browser up to 2 million cells and export as JSON, CSV or XLSX.
Why does Customs district and port breakdown matter when choosing a dataset?
National trade totals cannot say whether your region's gateway is gaining or losing volume. District and port attribution turns customs records into infrastructure and market-access evidence.
- Port choice is observable. With state-of-destination and port-of-entry in one report, importers can compare clearance points for the same commodity and partner.
- Cell limits shape question size. The 2-million-cell ceiling per generated report means broad commodity x geography x time cubes must be split into multiple pulls.
- Free but structured access. The platform is commercial delivery terms and needs no account to build reports; only saving report definitions requires an email and PIN.
How do you evaluate Customs district and port breakdown in a data source?
- Choose the right dataset variant first. USA Trade Online separates HS district, port and state datasets plus NAICS-based variants - select before setting dimensions.
- Verify the geographic dimensions you need. The record documents state, Customs district and port breakdowns with partner-country detail; confirm all three appear in your test report.
- Respect the report cell limit. Two million cells per report is the documented ceiling - plan extracts around it rather than discovering it mid-pull.
- Check format options. JSON, CSV and XLSX exports are documented; validate encoding of suppressed rows/columns before automation.
- Note the account posture. No login is needed to build or export reports; an email with one-time PIN is required only to save definitions.
