International shipping. What to expect.
We ship worldwide, and international shipping usually goes smoothly.
Please note that you’ll be responsible for any duties or taxes once your order arrives in your country. The carrier will typically contact you to complete the necessary steps for delivery—this often includes paying applicable fees or taxes.
All imported goods must go through customs, which is entirely outside of our control. This process can take anywhere from a few hours to several weeks, depending on your country’s regulations.
Once your order ships, you'll receive a tracking number. We see the same tracking updates that you do, so we recommend keeping a close eye on them to stay informed.
