Orders are normally prepared within 2–4 business days after payment confirmation. During holidays, promotional periods or unusually high order volume, processing may require up to 5 business days.

Standard shipping to supported United States destinations generally requires an estimated 10–15 business days in transit after dispatch.

Available shipping options and applicable charges are calculated and displayed at checkout before payment is completed.

Depending on product location, inventory availability and destination, orders may be fulfilled from our facilities or designated fulfillment partners. The physical shipping origin may differ from our business registration address.

After dispatch, available tracking information will normally be provided by email or through the applicable order-tracking method.

If tracking has not updated for an extended period, the shipment appears lost, or a delivered package cannot be located after reasonable checks, contact service@tdmaciu.com with your order number.

Eligible products may be returned within 30 calendar days after confirmed delivery.

Email service@tdmaciu.com with your order number, the item you want to return, your reason for returning it and photos or videos where relevant.

Do not automatically send merchandise to our business registration address. The correct return warehouse address will be provided after approval.

Customers are generally responsible for return shipping costs for preference-based returns.

Where an item is damaged, defective, incorrect, incomplete or materially different from its description because of a product or fulfillment issue, we will provide an appropriate solution without requiring the customer to bear additional costs resulting from that error.

Approved refunds are issued to the original payment method and generally processed within 5–10 business days after the returned item has been received and inspected.

Contact us promptly if you wish to request cancellation before fulfillment begins. Cancellation cannot be guaranteed after fulfillment has started.

No cancellation fee is charged when an order is successfully canceled before fulfillment.

Contact us with your order number and supporting photographs or videos where appropriate. After review, we will provide a reasonable replacement, refund or return solution depending on the circumstances.
