After payment confirmation and any necessary order verification, orders are normally processed within 24–48 business hours. During holidays, promotions, or unusually high order volumes, processing may require up to 3 business days. Business days generally exclude weekends and public holidays.

For standard shipping to supported United States addresses, estimated delivery is generally 10–15 business days after dispatch. This estimate does not include order processing. Actual delivery may vary because of destination, carrier operations, customs, weather, local disruptions, or other circumstances outside our control.

Available shipping methods and applicable charges are calculated and displayed during checkout based on the destination and available delivery service. The total shipping cost is shown before payment is submitted.

Depending on inventory availability, products may be packed and shipped from different fulfillment locations. The physical shipping origin shown on a parcel may therefore differ from the registered business address of Shenzhen Hengxingnuo Technology Co., Ltd. Products in the same order may occasionally be shipped separately.

Once an order has been dispatched and tracking information becomes available, a shipping confirmation containing the tracking number is normally sent to the email address used during checkout. Carrier scans can take time to appear. The carrier used may vary by product, destination, and available shipping service.

Please review your name, delivery address, apartment or unit number, postal code, and contact information carefully before submitting your order. If you discover an error after ordering, contact us immediately. We can request a change only if the order has not yet been shipped and the fulfillment partner can accommodate it. Incorrect or incomplete details may cause delay, return, or additional shipping costs.

Availability for P.O. boxes, APO/FPO addresses, and U.S. territories depends on the product, destination, and carriers available at checkout. If an address is not supported, checkout may prevent shipping to that location or ask you to use another address.

Temporary gaps in tracking updates can occur while a parcel moves between facilities, carriers, or shipping networks. If tracking has not updated for an extended period or the shipment appears significantly delayed, contact us with your order number and tracking information.

If a package appears to have been lost while in transit, contact customer support with your order number. After the carrier’s investigation, we will provide an appropriate replacement, refund, reshipment, or other reasonable solution where the loss is confirmed.

If tracking shows “Delivered” but you cannot locate the parcel, first check the delivery area, mailbox, household members, building reception, neighbors, and the carrier where appropriate. If it remains missing, contact us promptly so we can review the available delivery information and advise on next steps.

Contact us promptly if your order arrives damaged, incomplete, incorrect, or materially different from its product description. Include your order number, a description of the issue, and clear photos of the item and packaging where appropriate. We will review the issue and explain the applicable remedy.

Zynqelo™ primarily serves customers in the United States. Where delivery to another destination is available, applicable shipping options are displayed during checkout. International deliveries may involve customs duties, import taxes, brokerage fees, or other charges imposed by the destination country; unless clearly stated otherwise at checkout, such charges are the customer’s responsibility.
