All products being returned to Zysen for repair must be shipped with the shipping charges prepaid. Items returned to Zysen from outside of the China must include two copies (one copy placed in shipping container, one copy affixed to the outside of shipping container) of a Proforma invoice which ONLY states “Repair unit, no commercial value, and declare USD5 for Custom value”.

Whenever possible, the product should be shipped back to Zysen in the original packaging. Items subject to "in-warranty repair" will be returned to the buyer at no charge. The customer will be responsible for return shipping charges for items that are out of warranty or that have been mishandled in addition to the evaluation and repair charges as outlined below. For units returned and subsequently found to have no defects, an evaluation fee will be charged for any testing and processing regardless of warranty status.

REPAIR COSTS

Warranty repairs will be made at no cost to the customer. Units out of warranty or those, which have been mishandled, will require written approval from the buyer authorizing the repair charges prior to the repair being completed. Evaluation charges for an out of warranty or mishandled unit will be provided for components. Zysen will provide a cost estimate for any applicable repair charges. For those items which are determined to be beyond economical repair or where the buyer may decide against repairing the unit based on the cost estimate, the above specified evaluation fee will be charged. This evaluation fee may be applied toward the procurement of a replacement part.
