Shipping Destination and Origin
We sell and ship to customers in the United States. Orders are dispatched from Tianjin, China, at the address below. We do not represent these products as shipping from a United States warehouse. Available delivery services and address eligibility are shown at checkout.
Order Processing and Delivery Estimates
- Order processing: 1–3 days after successful payment and receipt of complete delivery information.
- Transit time: estimated 3–7 days after dispatch.
- Estimated total time: approximately 4–10 days from order processing through delivery.
These time periods are stated in calendar days. Transit estimates are not guaranteed delivery dates. Customs inspections, carrier disruptions and severe weather can cause delays. We will not use these circumstances to remove rights provided by applicable law.
Shipping Charges
Orders with a merchandise subtotal of US$20 or more after discounts, before shipping and taxes, qualify for free standard shipping. For orders below US$20, the shipping charge is displayed at checkout before you place your order. Applicable taxes and any charges we collect are also shown before payment.
International shipments may be subject to customs procedures. Contact us before ordering if you need clarification about any import charges not included at checkout; this policy does not promise duty-paid delivery or create an undisclosed fixed customs charge.
Order Tracking
When tracking is available, dispatch confirmation will include the tracking information. Please contact [email protected] if an order has not arrived within its estimated delivery period or if tracking appears incorrect.
Shipping Delays, Cancellation and Missing Parcels
If we cannot dispatch within the stated processing period, we will notify you, provide a revised dispatch estimate and offer the option to consent to the delay or cancel unshipped merchandise for a full refund. Any additional delay will be handled in accordance with applicable law.
Contact us promptly about incorrect delivery information. We will attempt to make changes before dispatch, but changes after dispatch may not be possible. For lost, damaged or incorrectly delivered parcels, contact us so that we can investigate with the carrier and arrange an appropriate replacement or refund. A carrier investigation does not remove your statutory rights.
Returns
Eligible return requests must be submitted within 7 days after delivery. Please read our Return and Refund Policy. Returns are sent to Tianjin, China, rather than a US return center.
