Hi @et_123 that’s usually not the duty itself — it’s UPS’s brokerage/customs-clearance fee.
Switzerland’s low-value threshold is lower than a lot of people think, so a CHF 77 order is often already over it. Even if the actual duty is zero, UPS can still charge for clearing the package.
If you’re using UPS Standard, there’s usually no real way around that fee. The practical fix is to use a different carrier/postal service with lower clearance fees, or a UPS Express/Expedited service where brokerage is often included.
DDP can stop the customer getting surprised at delivery, but it doesn’t make the fee disappear — it just changes who pays it.
