APPENDIX O
DEFINITION OF TERMS
O-1. Purpose. This appendix provides clarification of terminology used in the Waterborne
Commerce Statistics Program.
O-2. Definitions. For the purpose of this appendix the following terms unique to Waterborne
Commerce are defined as:
a. Commerce - Domestic. Contiguous and non-contiguous states and territories
constitute the geographical space upon which domestic commerce may be transported. This
includes Hawaii, Alaska, the 48 contiguous states, Puerto Rico and the Virgin Islands, Guam,
American Samoa, Wake Island, and the U.S. Trust Territories. Certain movements are excluded
from domestic commerce:
(1) Coal and petroleum products loaded from shore facilities directly into bunkers of
vessels for fuel.
(2) Insignificant amounts of Government materials (less than 100 tons) moved on
Government-owned equipment in support of Corps projects.
b. Commerce - Foreign. Waterborne import and export traffic between the United States,
Puerto Rico and the Virgin Islands, and any foreign country. These statistics do not include
traffic between Guam, Wake Island and American Samoa, and any other foreign country.
(1) Foreign commerce data are furnished to the Corps of Engineers by the Bureau of the
Census under a working arrangement sponsored by the Office of Management and Budget. The
data are confined to vessel movements by water and are reconcilable with published reports of the
Bureau of the Census, with the exception of LOOP Oil Terminal and Skagway Wharf reports,
which are manually entered as imports/exports by the Corps of Engineers.
(2) The Republic of Panama is considered a foreign country. However, individual vessel
movements with origin and destination at United States ports traveling via the Panama Canal are
considered domestic traffic. Alaskan crude oil (origin at Valdez, AK) shipped via the Panama
pipeline (west to east) and destined for gulf and east coast ports is also considered domestic
commerce.
(3) Import and export shipments for use by the United Stares Armed Forces abroad are
not reported to WCSC. Export shipments under the various foreign aid programs on Department
of Defense operated vessels, either American flag commercial vessels under time, voyage, or
space charter or vessels owned and operated by the Department of Defense, and various items
(listed by the Census) which affect National security are not published in terms of the individual
commodities shipped. Instead, a lump sum tonnage figure is complied and appears in these tables
as exports under commodity 9900, "Unknown or NEC."
c. Monthly Reports. These reports shall be made on ENG Forms furnished upon request
of the vessel operating companies to the WCSC. Data may also be furnished on an authorized
automated equivalent to the ENG Forms.
