I send equipment to Slovak factories every month and had similar concerns at the start. What worked was using a dedicated route service instead of random carriers. The company I use for freight to Slovakia has experience with machinery and industrial parts so they know how to pack and secure heavy items. Transit takes around four days which is reasonable for that distance. They also handle all the customs paperwork which matters when you're shipping technical equipment that needs proper documentation. Tracking is reliable so you can see where the shipment is instead of just guessing. For regular business shipments it's worth paying a bit more for a carrier that specializes in that route rather than the cheapest option you find online
