If you need a destination-specific estimate, customs document check, or wholesale shipment arrangement, contact our team before payment confirmation so the order pathway can be reviewed in advance.

Order review and confirmation

Orders placed through this website are subject to stock review, payment confirmation, destination screening, and final confirmation by our team. Submission of an order or inquiry does not guarantee immediate acceptance or same-day dispatch.

Processing timeline

Standard in-stock retail orders are generally reviewed and prepared within 1 to 3 business days. Wholesale, OEM, ODM, custom packaging, and documentation-heavy orders may require additional coordination time before dispatch.

Shipping methods and delivery estimates

Available carriers and delivery windows vary by destination, order size, customs requirements, and local service conditions. International deliveries are typically estimated after order review, and transit times shown during communication are estimates rather than guaranteed delivery commitments.

Customs, duties, and destination compliance

For cross-border shipments, customers are responsible for confirming that imported products, labeling, and documentation are acceptable in the destination market. Import duties, taxes, brokerage fees, and customs-related delays are determined by local authorities and are generally the responsibility of the buyer unless otherwise agreed in writing.

Address accuracy and delivery issues

Customers are responsible for providing complete and accurate shipping information. We are not responsible for delays, storage fees, return charges, or delivery failures caused by incorrect addresses, refusal of delivery, or inability of the carrier to complete the shipment after reasonable attempts.

Damaged parcels and shipment questions

If a parcel arrives visibly damaged or if there is a shipment concern, contact our support team promptly with the order reference, destination details, and clear photos of the external packaging and product condition so the case can be reviewed with the relevant service providers.
