Why isn commodity information available at the port level?
Currently, port data, combined with commodity and other geographic information (such as state) cannot be released due to disclosure regulations, determined by the U.S. Census Bureau. Customers interested in only port data and commodity information can contact the Census Bureau’s Foreign Trade Division for information on products they have that might suit their needs. Contact information for the Foreign Trade Division Data Dissemination Branch can be found here: http://www.census.gov/foreign-trade/contacts/whowho.html#data_dissemination. Starting 2007, commodity by port at country level data are available online. Click here to query.
