Q: Are there any restrictions on international orders regarding customs duties and taxes?
A: International orders may be subject to customs duties, taxes, and import fees levied by the destination country. These charges are the responsibility of the recipient and are determined by the customs authorities. It's advisable to check with your local customs office for information on potential fees before placing an international order.
Q: Can I buy products as a guest or do I need to create an account?
A: We support guest checkout. There are three steps for you to buy products as a guest. First, you should place an order. Then, you can proceed to the checkout process. Last, you should make a payment. If you only purchase as a guest without creating an account, you’ll miss out on the benefits of being a member.
Q: How can I check the shipping status of an order?
A: On the order page, you can view the shipping status of your order. Once the order is shipped, we will provide corresponding logistics information, including the logistics company and tracking number, so you can track the delivery progress of your order.
