ITC was founded on February 24, 1972 to construct and operate terminal assets.

In 1974, a dock which the facility was leasing from Union Equity became available for sale. Included in this purchase was an existing warehouse built over the dock that was used to store bagged rice for export. Mitsui purchased a 50% interest in the dock, storage warehouse, and deepwater berth which increased the size of the facility by an additional 18 acres.

Another opportunity was presented when Rollins Environmental Services offered to sell their interest in a dock and 135 acres of land. This property was south of Tidal Road and was not contiguous to the existing 18 acres. ITC successfully acquired the 135 acres from Rollins, but eventually resold 80 of these acres back to Rollins.

By 1976, with dock ownership and the newly acquired acreage, ITC constructed a key installation for Exxon Chemical Company. The Terminal built four 25,000-barrel semi-refrigerated 15 pound spheres for the storage of Butadiene, Crude Butadiene, and Butene-1.

ITC finalized an operating agreement in 1977 with ExxonMobil to operate its Anchorage terminal in Port Allen, Louisiana, which stores and handles Butadiene and Propylene.

Another milestone occurred in 1983, when an additional 96 acres were purchased from the Fluor Corporation. This property which is contiguous to the original 11 acres also included Fluor’s barge dock on Tucker Bayou and a warehouse. The warehouse was immediately resold, together with approximately 10 acres to the Valvoline Company.

Further acquisitions were made in 1993 with a purchase of 87 acres, two docks, and 20,000 feet of rail from the old Union Equity Cooperative.

Final acquisition occurred in 2003 with the addition of the Global Octane property of 27 acres. With the completion of this transaction, the Deer Park facility now approximated 265 acres.

In 2008, ITC entered into a Joint Venture terminal agreement with Rubis to build a new facility in the Port of Antwerp.

Terminal operations at ITC Rubis Terminal Antwerp started in October 2010 and further expansions are continuing.

In July 2010, ITC acquired 180 acres of land on the Houston Ship Channel in Pasadena, and work is ongoing to develop this new site to a world-scale petroleum and petro-chemical terminal.

In 2011, ITC became RC 14001:2008 certified and expanded storage capacity by an additional 965,000 barrels of storage.

In 2013, ITC Deer Park continued expanding storage with an additional 900,000 barrels at the Deer Park facility

In May 2015, ITC Pasadena commissioned its first tanks and began moving product. Additional tanks were added and commissioned in July 2016 bringing the terminal to 3.3 million barrels of capacity. In July 2017, necessary permitting was received allowing ITC to construct another 4.2 million barrels of storage at Pasadena.

ITC Pasadena commenced operations in September 2017 to the Colonial and Explorer pipelines.

ITC Pasadena completed its third phase expansion project and commenced the operation.
