Processing begins after payment has been successfully received. Holidays are excluded.

During peak seasons or high-volume periods, processing times may be extended.

Orders paid using alternative payment methods, including ACH, Zelle, bank transfer, crypto, and similar options, will begin processing once payment has been fully confirmed.

We offer several shipping options to fit your needs and timeline.

• USPS Priority Mail: Typically delivers within 2-5 business days in the United States, depending on destination.
• UPS 3 Day Select: A UPS service tier. Actual delivery timing may vary based on destination and carrier conditions.
• UPS 2nd Day Air: A UPS service tier. Actual delivery timing may vary based on destination and carrier conditions.
• UPS Next Day Air: A UPS service tier. Actual delivery timing may vary based on destination and carrier conditions.

Service names such as 2nd Day Air or 3 Day Select refer to UPS carrier service tiers and are not a guarantee of delivery within that number of days.

All delivery timeframes are estimates and may be affected by weather events, operational delays, carrier disruptions, or other factors outside our control.

We offer optional Shipping Insurance on eligible orders. Protection applies only to qualifying shipping issues where a package is lost in transit, stolen in transit, or damaged upon arrival.

Shipping Insurance does not cover packages after confirmed delivery by the carrier. Once a shipment has been marked delivered to the address provided at checkout, theft, loss, or mishandling that occurs afterward — including from a residence, mailbox, porch, parcel locker, mailroom, front desk, or other delivery location — is not covered by Shipping Insurance.

If you did not add Shipping Insurance and experience a covered transit issue, we will do our best to assist, but our ability to offer a replacement or other resolution may be limited once a package has been accepted by the carrier.

A tracking number will be emailed to the address associated with your order as soon as the shipment is processed.

Depending on the carrier, tracking updates may take up to 24 hours to appear in the carrier’s system.

If your shipment arrives with missing, incorrect, or damaged items, please notify us within 72 hours of delivery. Include your order number and supporting details, including photos if applicable.

We will review the information provided and offer an appropriate resolution.

Once a package has been accepted by the carrier, the carrier is responsible for transporting the shipment to the delivery address provided at checkout.

If your package is delayed or appears lost before confirmed delivery, we recommend the following steps:

• Review the latest tracking updates and allow time for delayed carrier scans to appear.
• Contact the carrier directly to initiate a trace or investigation when appropriate.
• If you purchased Shipping Insurance and the shipment qualifies as lost or stolen in transit, contact us with your order details so we can review the issue and handle the resolution process.
• If you did not purchase Shipping Insurance, contact us with your carrier case number and order details and we will assist where we can.

Customers must ensure all shipping information is correct at the time of ordering.

Orders shipped to incorrect or incomplete addresses due to customer error are not eligible for replacement or refund.

Order changes or cancellations may be requested before the order has shipped. Once an order is in transit, it cannot be modified or cancelled.

Cancellations not resulting from an error on our part may be subject to applicable restocking fees as outlined in our Terms and Conditions.

Some research materials may require careful handling. Orders are packaged for standard transit, but customers are responsible for promptly retrieving packages upon delivery to help protect product integrity.

All products are shipped strictly as laboratory research materials. They are not intended for human or animal consumption, and no claims are made regarding safety or effectiveness outside controlled research environments.
