ANSAC's member companies place significant emphasis on high quality standards. Each producer utilizes extensive internal quality control procedures to guarantee a continual high quality product. ANSAC also employs strict procedures to ensure that our customers receive the same high quality product leaving the plants.

Quality Testing

The primary responsibility for guaranteeing compliance with product specifications lies with the producers, but periodic sampling is conducted by ANSAC as follows:

  • samples are taken from rail-cars after the material has left the plant
  • independent labs test these samples for compliance with ANSAC's product specifications

In twenty five years of operation, ANSAC has detected only one incidence of non-compliance.

Handling of Quality Complaints

All quality complaints are handled through ANSAC's sales offices. When laboratory analysis is required ANSAC contracts the work out to independent labs or utilizes member company laboratories.
