The report indicates that Swarovski uses a variety of both semi-finished and finished components. To quote:
• Our global supplier network contains more than 500 suppliers in more than 35 countries. More than 100 of them supply parts and components that are incorporated directly into our products (p.70)
• We purchase glass blanks from Germany and Asia, while metal and molded parts mainly come from Europe . . . The semi-finished products and components that we purchase from suppliers include plastic parts, electronic components, gaskets, screws, accessories such as straps, bags, tripods or smartphone adapters, and many more (p.71)
• Electronic components are purchased and integrated into our products. In our development, manufacturing, and repair activities, we find it a challenge keeping pace with the short life cycles that electronic components have (p.93)
