General information about processing, tracking, delivery, and controlled research logistics.
Shipping confirmation
A confirmation is sent after the carrier accepts the package. Review the destination details before placing an order.
Tracking
Use the carrier tracking link to monitor progress. Carrier scans can take time to appear after the label is created.
Cold shipping
Cold shipping requirements vary by product and documented storage conditions. Follow the product label and lot documentation rather than assuming one requirement for every compound.
Delayed or lost packages
If tracking stalls or a shipment appears lost, contact support with the order number after reviewing the carrier's latest update.
Research logistics
Retain the packaging, lot identifier, and supplied documentation when receiving materials into a controlled laboratory workflow.
