Shipping Policy

Effective Date: August 10, 2026

At MCDUTECH, we are committed to getting your order to you as quickly and safely as possible. Please review the following information regarding our shipping and delivery practices.

Order Processing

Orders are typically processed and prepared for shipment within 1–3 business days, Monday through Friday, excluding holidays.

Orders placed on weekends or holidays will begin processing on the next business day.

During periods of high order volume, product launches, promotions, or holidays, processing times may be slightly longer. If there is an unexpected delay with your order, we will make reasonable efforts to notify you.

Shipping Methods & Delivery Times

Available shipping options and rates are displayed at checkout based on your shipping address, order size, product weight, and available carrier services.

Estimated delivery times are provided by the shipping carrier and may vary depending on your location and the shipping method selected.

Typical domestic delivery times are:

• Standard Shipping: Approximately 3–7 business days

• Expedited Shipping: Delivery times vary based on the service selected at checkout

Please note that shipping times are estimates and are not guaranteed delivery dates.

Shipping Confirmation & Tracking

Once your order has shipped, you will receive a shipping confirmation email containing your tracking information.

Tracking information may take up to 24–48 hours to become active after the shipping label has been created.

You can use the tracking number provided in your shipping confirmation to monitor the status of your shipment.

Shipping Address

Customers are responsible for providing a complete and accurate shipping address at checkout.

MCDUTECH is not responsible for delays, additional shipping charges, or packages returned to us due to:

• Incorrect or incomplete addresses

• Missing apartment, unit, or suite numbers

• Incorrect ZIP codes

• Refused deliveries

• Failure to retrieve a package from the carrier

If you notice an error in your shipping address after placing an order, please contact us as soon as possible. We will make every reasonable effort to correct the address before the order ships, but we cannot guarantee that changes can be made after fulfillment has begun.

Lost, Stolen, or Misdelivered Packages

Once an order has been shipped, delivery is handled by the selected shipping carrier.

If tracking shows that your package was delivered but you cannot locate it, please first check with household members, neighbors, and the carrier's delivery information.

MCDUTECH is not responsible for packages that are confirmed by the carrier as delivered to the address provided at checkout.

If you believe your package has been lost or misdelivered, please contact us so we can assist you in working with the carrier.

Damaged Shipments

Please inspect your package when it arrives.

If your order arrives visibly damaged, please take photographs of the packaging and product and contact MCDUTECH as soon as possible.

For concealed damage, please contact us within 48 hours of delivery and provide photographs of the product, packaging, and shipping label when requested.

We will work with you to determine the appropriate resolution.

Backorders & Out-of-Stock Items

If an item becomes unavailable or is placed on backorder after your order is submitted, we will contact you with available options, which may include waiting for the item to become available or requesting a cancellation where applicable.

International Shipping

Unless otherwise stated on the product page or at checkout, MCDUTECH currently ships to addresses within the United States.

International shipping may be available for select products in the future. Any applicable customs duties, taxes, tariffs, or other import fees are the responsibility of the customer unless otherwise stated at checkout.

Shipping Delays

MCDUTECH is not responsible for shipping delays caused by circumstances outside of our reasonable control, including but not limited to:

• Severe weather

• Natural disasters

• Carrier delays

• Transportation disruptions

• Holidays

• High shipping volumes

• Address-related issues

• Customs or government delays

• Other unforeseen circumstances

Carrier delivery estimates are provided for convenience and should not be considered guaranteed delivery dates.

Order Cancellations

If you need to cancel an order, please contact us as soon as possible.

Cancellation requests can only be guaranteed if the order has not yet entered the fulfillment or shipping process. Once an order has shipped, it may no longer be eligible for cancellation and may instead need to be handled under our return policy.

Returns

For information regarding returns and refunds, please see our Return Policy.

MCDUTECH currently allows eligible customers to request a refund within 30 days of the shipment date, subject to the requirements of our Return Policy. A return authorization must be obtained from customer service before returning a product. Products must be returned in good physical condition with all original parts and components included.
