Contact before returning
Do not send material back without written return instructions. Contact support with the order number, internal lot number, a description of the concern, and photographs when relevant.
Research materials
Because chain of custody and storage conditions cannot be confirmed after delivery, opened or shipped research materials generally cannot be returned to available inventory.
Shipment errors
Incorrect items, verified transit damage, or quantity discrepancies should be reported promptly. We will review the order and lot records before determining replacement, credit, return, or another appropriate resolution.
Quality concerns
Quality concerns are recorded against the affected product, lot, and orders. Material may be placed on hold while the report, retained sample, supplier records, or laboratory evidence is reviewed.
Cancellations
An order may be cancelled before payment verification or fulfillment begins. Once fulfillment has started, cancellation may no longer be possible.
