PLEASE NOTE: As of August 2025 the US government removed the de minimus exemptions that allowed shipments under $800 to enter the US without the payment of duties or Customs Clearance Fees.

Therefore, US Customs now charges a Customs Clearance Fee on all orders going to US customers. This fee is billed to US customers by UPS or USPS.
