Manufacturing plants have certificates of quality systems ISO 9001, IS014001, ISO/TS 16949, which guarantees high standards and stable product quality. Each plant has its own testing center.

 Also special attention is paid to the improvement of production technology, updating of machines and other equipment. Such a well-established production mechanism ensures stable quality of HDE products, and even in case of accidental problems, we are ready to replace the goods, thanks to the flexible conditions of the warranty policy.

     In fact our task is not only to increase sales and acquire new customers, but the building of strong, long-term partnerships with existing customers. We seek to gain confidence of our customers, so the company HDE successfully implements its warranty program.

The warranty period for HDE products is 6 months or 20,000 km of run, whichever comes first, subject to storage and installation requirements. The warranty period is calculated from the date of transfer of goods to the buyer.

The warranty does not cover the wear during operation, incorrect installation and misuse
