btn Matrix Chemical HOME PRODUCTS SALES LOGISTICS QUALITY VENDORS CONTACT QUALITY Matrix carefully chooses producer partners from select countries – a high standard that is rare in our business. We hire independent inspection companies to check each shipment at the origin port for packaging and quality. All products are tested and samples are retained for up to 6 months. Although these measures come at a cost to us, these steps are critical to our intensive quality control system – and explain why Matrix customers never worry about rejecting a shipment. Our uncompromising standards are evident in the sample inspection report below. Matrix Chemical 151 CALLE DE SAN FRANCISCO STE 200 PMB 5559 SAN JUAN, PR 00901-1607 © 2021 Matrix Chemical Inc., Contact
