Quality Program

Erie Coke Corporation pledges to continue to adhere to its Company policy of "Quality through Consistency and Commitment." Since the awareness and insight of tomorrow rely upon the knowledge and decisions of today, our employees remain dedicated to work for continued improvement in product quality and customer service.

In 1997 Erie Coke set a goal that would not only further establish our integrity, but also allow us to remain competitive in the new millennium. We set out in earnest to achieve ISO 9002 & QS-9000 Registration, and in December 1998 this objective was reached.

In May 2016 the company made a successful change to the ISO 9001:2015 quality system and gained unconditional approval for continued registration.

Erie Coke's accredited quality system positively enhances our ability to consistently provide the customer with a product and services among the highest standards in the industry.

The ISO quality system not only enables us to provide the automotive industry with a superior product, but also confirms our


status as a reliable and respected supplier to many other sectors of the manufacturing world for many years to come.

Product Quality

Erie Coke customers expect - and get - a high performance coke product. By utilizing the latest technology, our laboratory technicians analyze raw materials for the critical properties of ash, sulfur and fluidity. These test results dictate the precision blends that yield the highest-caliber coke product.


Unless the customer makes a specific size request (which often can be accommodated!), our coke is typically separated into a variety of sizes, with 6x9 inches, 4x9 inches, 4x6 inches, 2x4 inches & 1x2 inches being the most common.
