Industrial Products


Anhydrous Ammonia (NH3) is one of the most highly produced inorganic chemicals with over 170,000,000 tons produced worldwide. NH3 is the base chemical for many fertilizer products. As a result the fertilizer industry uses 80% of the produced NH3. Ammonia is also used in the production of plastics, fibers, explosives, nitric acid and intermediates for dyes and pharmaceuticals.

IOC is a domestic leader in the distribution of ammonia to industrial users. On a weekly basis we supply barges, railcars and trucks to some of the largest chemical buyers in the Americas. Through our various supply points we have the ability to meet all of our customer’s needs in a logistically efficient manner and have the ability to supply railcars that originate on all of the major US rail carriers.


Sulfur is abundant thru out the world.  Almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum. This byproduct in the United States is traded in the form of Molten Sulfur.  Molten sulfur is the primary raw material at PCI.  IOC is an active buyer of all the molten sulfur required for PCI’s production facility in Pasadena, TX.


Sulfuric acid is the largest-volume industrial chemical produced and is often referred to as the “universal chemical”.

At PCI in Pasadena, TX sulfuric acid has been produced since 1949. The current sulfuric acid plant was upgraded in 2014. It provides the feedstock for PCI production of granulated ammonium sulfate. At PCI, the products produced are “primary products”, not by-products of other processes. Each product is “purposely made” to exacting specifications to ensure the highest quality, compatibility, and blendability. IOC is the exclusive marketer of the ammonium sulfate and the sulfuric acid produced at PCI. These products can be loaded in a truck 24/7 or rail cars originated via the BNSF and UP, as well as barge and vessels at the deep-water docks located on the Houston ship channel at PCI Nitrogen.
