What it assesses and how
SQAS is an assessment system run by Cefic (the European Chemical Industry Council) that evaluates logistics service providers to the chemical industry on safety, quality, environment and sustainability in a uniform way. The assessment is carried out by an independent assessor accredited by Cefic, and the result is a report that customers can consult, not a pass or fail. There are modules for each activity: Transport Service, Tank Cleaning, Warehouses, Rail and Distributors (ESAD).
It is not a certification
This matters: SQAS is not a certification but an assessment. The reassessment cycle is three years and it currently covers Europe. Many chemical shippers require it from their hauliers as a condition for working with them.
