Switzerland generates more hand carry demand per head than almost any country on earth, and the reason is the value density of what it makes. A watch movement, a reference standard, a batch of investigational product, a single piece of precision micro-engineering, all small, all worth a great deal, and all carrying either a stability window or a custody requirement that an ordinary parcel network is not built for.
Basel is the specific engine. The pharmaceutical and life science cluster around it runs deep and permanent relationships with American sponsors, laboratories and regulators, and the resulting traffic is exactly the kind that hand carry serves: investigational medicinal product against a trial visit, comparator material, reference standards, and clinical samples whose stability window is the real deadline rather than the delivery date.
The administrative point matters as much as the commercial one. Switzerland is not in the European Union or its customs union, which means a consignment for Zurich is a separate import from one for Frankfurt even when they travel together as far as Germany. That is a decision to be taken at quotation. It also means the country has its own regimes for medicinal products, precious metals and cultural property, and those sit on top of ordinary customs rather than inside it.
