Shipping & Delivery

Because Commercial Industrial Supply caters to contractors and commercial and industrial clients, we arrange shipping and delivery on a case by case basis. We are committed to finding shipping solutions that meet your specific needs in both timeliness and cost efficiency. That’s why our service team works with you one-on-one to determine the best shipping method for your order.

Though CIS may work tirelessly to ensure your shipments are on time and damage-free, occasionally damage does occur during shipment. We ask that you inspect your shipment for damage upon receiving it. If damage is noticeably present on your package(s) a note should be made to the shipping company at the time of delivery, or the shipment should be denied entirely on the basis of damage. This will best ensure quick and easy processing of any damage claims.

-       Internal record keeping.

-       Improving our products and services.

-       Providing you with CIS promotional offers.

-       Internal research purposes.

We are committed to ensuring that your information is secure. In order to prevent unauthorized access or disclosure, we have put in place physical, electronic and managerial procedures to safeguard and secure the information we collect.
