5. Customs & Import fees

Such as the products you buy on our site - can't simply be shipped freely from country to country. When goods are imported into a different country or customs territory, there is a charge called Customs Duty that must apply. This is charged by the local customs authority where the goods are being imported into.

If Customs Duty is payable to your territory, you'll be responsible for paying it to the authorities, so SunFounder isn't involved in this process. Whether Customs Duty is payable, and by how much, depends on a whole lot of different things. For example, many countries have a 'low value threshold' below which they do not charge any Customs Duty.

If you do have to pay Customs Duty though, the amount payable is usually calculated based on the value of the goods and the type of goods being imported.

AND IF I DON'T PAY THE CUSTOMS DUTY?

If, for whatever reason, you refuse the customs fee and the parcel is returned back to us. If you're still unsure on whether you'll be subject to customs fees, we recommend contacting your local customs office for more info before placing your order!
