Shipping and Returns Policy

This Shipping and Returns Policy describes how Mollecule fulfills research material orders and how returns are handled. Timelines are estimates and may vary by carrier, destination, weather, and inventory.

Order processing

Orders are typically reviewed and processed on business days (Monday to Friday, excluding holidays). Researcher verification or compliance review may add processing time. You will receive a confirmation email when your order is placed and a shipment notification when a tracking number is available.

Shipping methods and destinations

Available carriers and rates are shown at checkout. We currently prioritize domestic U.S. shipping unless otherwise stated on the storefront. Some destinations, compounds, or package types may be restricted. You are responsible for providing a complete, accurate delivery address suitable for receiving laboratory materials.

Cold-chain and handling

Many products ship as lyophilized materials. Packaging is selected to protect products during transit under normal conditions. Upon receipt, store materials according to the product documentation and our Research Use Only handling guidelines. Delays outside our control (carrier issues, customs, incorrect addresses) may affect transit time.

Risk of loss

Unless required otherwise by law, risk of loss passes to you when the package is transferred to the carrier. Please inspect packages promptly and keep packaging if you need to report damage.

Damaged or missing packages

If your shipment arrives damaged, incomplete, or shows clear transit issues, contact us within 7 days of delivery at +1 (442) 398-0114 or through our Contact page with your order number, photos of the packaging and contents, and a short description of the issue. We will work with you and the carrier to determine a remedy (reshipment, replacement, or refund) at our discretion.

Returns

Because our products are research materials with storage and contamination considerations, returns are limited. Unopened items may be eligible for return authorization if you contact us within 14 days of delivery and the product remains in original, sealed condition. Opened, reconstituted, refrigerated-improperly, or otherwise compromised materials are generally not eligible for return.

All returns require prior written authorization (RMA). Unauthorized returns may be refused. Approved refunds are issued to the original payment method after inspection, less any non-refundable shipping charges unless the return is due to our error.

Cancellations

You may request cancellation before the order ships. Once a label is created or the package is with the carrier, the order is treated as shipped and follows the return rules above.
