We begin reviewing and processing your order after the online payment and order confirmation requirements have been completed. Preparation times may vary due to item availability, product type and warehouse operations.

The normal estimated delivery window of 2–7 days relates to eligible U.S. orders. We will advise customers where exceptional fulfillment circumstances affect their orders.

Shipping is available only to supported destinations presented in the live checkout. Availability may vary by product, address or logistics restrictions.

Battery-powered or electronic hydration products may be subject to additional carrier and destination restrictions where applicable.

For eligible U.S. orders, Standard Shipping is $2.99 USD and Express Shipping is $5.99 USD. Choose the available shipping option at checkout; the final fee is displayed before payment. No free-shipping threshold is currently stated.

Rates apply to eligible U.S. checkout deliveries. Shipping methods may not be available for every product or location. If a destination or shipment requires special handling, any applicable charges should be disclosed during checkout.

Estimated delivery for eligible U.S. orders is 2–7 days after order confirmation under normal fulfillment and carrier conditions. This is an estimated arrival window, not a guaranteed delivery date. Express Shipping is offered as a priority option; a separate express arrival time has not been confirmed and any more specific estimate will appear at checkout. Holidays, severe weather, remote locations, inventory constraints and carrier disruptions may affect delivery.

Contact customer service if your delivery exceeds the estimate or tracking remains inactive.

When the delivery service provides shipment tracking, a tracking number or status link may be shared in your order messages. A tracking number can take time to appear as active in the carrier’s system.

Please carefully check your shipping address and contact details before checkout. If you notice an error, contact us promptly. We may not be able to amend an address once the order has entered preparation or has been dispatched.

Availability for PO boxes, military addresses or other special delivery locations depends on the selected shipping service and the live checkout. Please confirm eligible delivery options before purchase.

Tracking scans and transit progress are controlled by the carrier. Unexpected delays may result from weather, transport interruptions, peak periods, customs or public holidays. Contact customer care if you need help reviewing the status of your shipment.

If your parcel has not arrived and the tracking status suggests an issue, send customer care your order reference and the relevant carrier information. We will review the available details and applicable remedies.

If a carrier marks a parcel delivered but you cannot locate it, check the delivery details and safe-drop areas, and contact the carrier or our team as appropriate. We will assess the situation based on the available information and your applicable rights.

Contact service@qelvazio.com as soon as reasonably practical with the order number and photographs where appropriate. We will review available options, including remedies that apply under consumer law.

If cross-border delivery is offered, taxes, customs charges, import restrictions or clearance requirements may apply depending on the destination. The information shown at checkout and applicable law should be reviewed before placing an order.

If a parcel cannot be delivered due to an invalid address, carrier limitations or other circumstances, please contact customer care for the available next steps. Any additional shipping or return charges depend on the specific situation, relevant terms and applicable law.
