I came across a useful write-up this morning in the Sacramento Bee(registration required) that discussed a number of the import and commodity price implications of Hurricane Katrina. Perhaps most useful was the list of "Hurricane-Hit Ports" and their major imports / exports. Unfortunately, the list of impacted ports goes far beyond New Orelans. A copy of this list from the article is below:
Port of Southern Louisiana, LaPlace
* Imports: crude oil, petrochemicals, steel, fertilizers, ores
* Exports: corn, soybeans, wheat, animal feed
* Fifth-largest port by tonnage in the world, largest in the U.S. Handles 15 percent of all U.S. exports by value.
Port of New Orleans
* Imports: metals, rubber, coffee, forest products, cement
* Exports: aluminum, iron, steel, animal and vegetable products, forest products
Port of Gulfport, Gulfport, Miss.
* Imports: tropical fruit, ore, metals
