Import duties, VAT, taxes, and brokerage fees are not included in your order total and must be paid by the recipient.

Customers are responsible for ensuring that all items ordered comply with their country’s import laws and for obtaining any required permits or documentation prior to purchase. We do not provide guidance on country-specific import requirements.

If a package is rejected, unclaimed, or returned due to unpaid duties, missing documentation, import restrictions, or an incorrect address:

• The order will be issued as store credit only
  
• Original shipping costs are non-refundable
  
• Any non-recoverable shipping or return fees may be deducted
  

If a shipment is lost, seized, or not returned, an insurance claim must be completed before any resolution is provided. If the claim is denied, no refund or credit will be issued.

Pressurized or restricted items will ship via ground services only where permitted.
