Return and Refund Policy

RETURN AND REFUND POLICY Research materials Because our products are research reference materials whose integrity depends on controlled handling, storage, and cold-chain conditions, we cannot resell returned items. All sales are final once an order has shipped, except as described below. Damaged, defective, or incorrect shipments If your order arrives damaged, if a vial is compromised, or if you received an incorrect item, contact support@patriotresearchlab.com within 3 business days of delivery. Include your order number, a description of the issue, and photographs of the outer packaging, the inner packaging, and the affected vials. Approved claims are resolved by replacement of the affected item or, at our discretion, a refund of the item price. Lost or undelivered packages If tracking indicates a package was lost in transit, contact us so we can open a carrier claim. Replacements are issued after the claim is resolved. Non-returnable situations We cannot accept returns or issue refunds for materials that have been opened, reconstituted, mishandled, or stored outside recommended conditions; for refusal to accept delivery; for incorrect shipping addresses provided by the customer; or for any product used outside the research-use-only terms. Order cancellations Because no payment is taken at checkout, an order request may be cancelled at no cost any time before the invoice is paid. Email us with your order number. Once payment is confirmed and the order is packed, cancellation is no longer available. Refund processing Approved refunds are issued to the original payment method used to pay the invoice. Allow 5-10 business days for the credit to appear. Contact support@patriotresearchlab.com
