Fulfillment timelines based on product location and production pathway
Lead times depend primarily on where a product is physically located and whether it requires manufacturing.
Each product page clearly indicates:
For international customers, delivery time is calculated by adding logistics transit time from the U.S. shipping location to the final destination.
Products may be located in:
*Delivery timing varies depending on geographic origin.
Products physically located in the United States typically ship within:
We maintain 130,000+ SKUs in U.S. inventory, with many products prepackaged and ready for immediate shipment.

For customers outside the United States:
Transit time varies by destination country, customs processing, and carrier.
*Customers are responsible for any import-related clearance requirements.
For custom synthesis or larger-scale quantities, lead times are defined during the technical feasibility review and confirmed in writing prior to order execution.
Our team evaluates synthetic complexity, raw material availability, scale requirements, and production scheduling to establish the most accurate delivery timeline.
