Waterborne commerce

Waterborne commerce is the USACE-measured flow of cargo over U.S. ports and navigable waterways.

The WCSC publishes it as annual tonnage, commodity and vessel-trip reports for roughly 820 PORT and WATERWAY locations.

In this catalog it appears concretely: - USACE Waterborne Commerce Statistics Center - U.S. Waterborne Commerce Data. - USACE WCSC (tagging) — "waterborne-commerce, commodities, inland-waterways, great-lakes". - WCSC coverage.geographic — "1,381 locations (819 PORT, 562 WATERWAY)".

Conventions decide whether two sources can be joined at all. Buy one side of an analysis that ignores this convention and every reconciliation step — calendar alignment, unit conversion, entity matching — lands on your team instead of the vendor's.

The failure mode is concrete: the label appears in a listing, the delivered files tell a different story, and the gap surfaces mid-project when fixing it is most expensive.

You rarely have to take a vendor's word for it. 82.4% of the 1,744 datasets Datadory catalogs are free to access, and USACE Waterborne Commerce Statistics Center - U.S. Waterborne Commerce Data lets you inspect the real artifact before any budget is committed.

Treat every claim of this attribute as testable:

1. Open USACE Waterborne Commerce Statistics Center - U.S. Waterborne Commerce Data and compare its listing against the delivered artifact before paying for a commercial equivalent.
2. Read USACE WCSC's record on tagging — "waterborne-commerce, commodities, inland-waterways, great-lakes" — then confirm the delivered artifact matches before you license anything.
3. Open WCSC coverage.geographic and confirm its record — "1,381 locations (819 PORT, 562 WATERWAY)" — against the files you actually receive.
4. Pin down update cadence in writing. Across this catalog, 22.6% of 1,744 datasets refresh daily and 64 still arrive only through a manual request form, so ask exactly how fresh each release is.
5. Check whether definitions are verified at all. Field definitions are verified for 1495 of 1,744 datasets (85.7%), and any source you license should meet that bar.
6. Price the delivery route before the license. In this catalog bulk download is the most common access method (725 datasets) ahead of official APIs (574), and 379 sources still require scraping — a maintenance cost that lands on you, not the vendor.
