Anybody knows if the polish company ZSM CHELMNO is a genuin supplier to Zetor for i.e. cylinder heads or just an aftermarket spare part supplier not supplying genuin spare parts?
What I meant was that if the company ZSM CHELMNO is an approved supplier to the Zetor supply chain, gives a guarantee that the quality is consistent with Zetor requirements. There are lots of good "spare" suppliers not beeing approved by Zetor and it might be difficult to judge their quality for a layman, not saying the quality is poor, but it can be expensive to take a chance.
The logistic part of the supply chain is of cause a vital part of the quality as the ISO standard stating.
