Amazon.com estimates import taxes on international orders and adds them as an "Import Fee" line at checkout, and its designated carrier clears Swiss customs, so the parcel normally arrives with nothing left to pay. The exception is an item a marketplace seller ships to you directly, which can still arrive with Swiss import VAT and a courier fee due.
Amazon's terms clearly describe a prepaid deposit and customs clearance, but I could not load an Amazon.com page that names Switzerland in the eligible-destination list, and no Reddit or Trustpilot report from a Swiss buyer surfaced to confirm that nothing is charged on delivery.
Amazon.com's International Shipping Terms & Conditions state that products for delivery outside the US are sold by Amazon Export Sales LLC, that Import Fees may apply, and that for certain destinations Amazon Export estimates them and collects an Import Fees Deposit at checkout. The same terms let Amazon appoint a designated carrier to act as the buyer's agent, clear the goods and pay the actual import fees out of that deposit, and they promise no top-up if the actual fees turn out higher, with a refund if the deposit was too high. Amazon's own help page describes this as import-fee estimation at checkout plus customs clearance on the customer's behalf. Amazon's Switzerland-specific guidance (on the European store) confirms the Swiss rates involved: 8.1% on most goods and 2.6% on books, shown to the buyer as an "Import Fee".
What complicates it is that the mechanism is a deposit paid to Swiss customs through the carrier rather than Swiss VAT charged by a Swiss-registered seller, and it only covers goods sold by Amazon Export or fulfilled by Amazon. Amazon's AmazonGlobal country page still carries the generic line that customs fees and import duties are the recipient's responsibility, and Amazon's seller guidance repeats that buyers of Amazon.com orders are responsible for import fees, which is consistent with the deposit model but reads as if nothing were prepaid. Where a third-party seller ships to Switzerland itself instead of through Amazon, no deposit is collected and the buyer settles import VAT and the courier's clearance fee on delivery. I could not verify the Swiss experience with recent buyer reports, so the finding rests on Amazon's own wording plus the fact that the Import Fee line is standard on AmazonGlobal checkouts.
An item sold and shipped directly by a third-party marketplace seller rather than by Amazon Export or FBA: no Import Fee is collected at checkout and the courier bills VAT plus a clearance fee on delivery.
