Material being returned is subject to inspection and a minimum twenty five percent (25%) restocking fee. Non-stock/ special order material is non-returnable.

Discontinued or Damaged Materials

In the event that material returned is either discontinued or damaged, MKS will contact the customer who will have the option of taking the material back at their expense or MKS Pipe & Valve may charge a fee for destroying the items on site.

Time Frame for Returning Materials

Customers are given 60 days to return the product once an RMA has been created; After this time, the RMA will no longer be valid and may be refused or assessed a higher restock fee.

Return Stipulations

  • The package must contain the MKS Pipe & Valve generated return authorization document, and the outside of the packaging must indicate the RMA number.
  • The shipment must be sent prepaid by the customer.

The only exception to these return stipulations would be a return as a result of an MKS Pipe & Valve error. If this happens, MKS Pipe & Valve will arrange to have the product picked up or provide an appropriate UPS account number for small shipments.
