Over 400 commodities are defined in Trade Currents’ analyses. They cover all U.S. imports and exports of goods as reported by the U.S. Census Bureau. Commodities are defined by groups of Harmonized System (HS) codes, with some defined by single-digit codes and others by groups of 4 or 6 digits. Commodities are also classified by North American Industry Classification System Codes (NAICS).
For each commodity, import and export value by mode of transport is reported for vessel, air, and land modes. Land value largely includes trade with Canada and Mexico, although some trade with other countries moves through the Canadian and Mexican borders. In addition to value by mode, data concepts for each commodity include containerized and non-containerized value and weight, and the number of loaded Twenty-Foot Equivalent containers (TEUs).
In addition to modal detail, data for each commodity includes countries of origin or destination and detail for five coastal ranges:
- Canada/Great Lakes
- Trade by air does not include coastal detail
