This section describes ZYGO's standard warranty relating to all ZYGO devices.







  1. Always accept the shipment.
  2. Note the damage on the delivery freight bill and have the carrier sign it, acknowledging the damage (i.e., "crushed, smashed, bent, torn carton," etc.). Send a copy of the notated freight bill to ZYGO-USA, Fremont, California.
  3. When damage is not always obvious, call the carrier, report the damage and request an inspection within 15 days of delivery. Save the container that held the damaged item(s), along with the merchandise for the carrier's inspection.
  4. Forward the carrier's inspection report and your description of the damage to ZYGO.
  5. Hold the shipment awaiting disposition, as claims may be disallowed by the carrier.
  6. If a replacement is required, enter a new, separate purchase order.





  1. Items may be accepted for credit only if accompanied by our billing reference or Invoice number. All items being returned must have prior approval from ZYGO-USA..
  2. Returned merchandise must be in new and re-saleable condition. Returned items may not include 'opened' bulk packages or kits.
  3. All returns are subject to a 15% re-stocking charge.
  4. It is the customer's responsibility to review the Sales Order Acknowledgement and advise ZYGO of any corrective action necessary. The re-stocking fee of 15% will apply on standard units and parts only. Custom and/or special units may be returned subject to re-stocking standard components only.
  5. Quantity/Term Discounts, as shown on the original Invoice, are subject to being deducted from the credit issued.
  6. If unit(s) return disqualifies the original Invoice quantity for Quantity/Term Discount, the entire Quantity/Term Discount will be subtracted from allowed credit.
