Definitions (In-Stock vs Made-to-Order)

Standard stock classification terminology

The following definitions explain how product availability is categorized on the 1Click Chemistry website.

These classifications determine expected lead times and fulfillment pathways.

In Stock (U.S.)

Material is physically available in the United States warehouse.

Ships typically within 1–2 business days
Inventory is allocated upon order confirmation
Delivery timeframe shown on the product page reflects U.S. shipment

In Stock (Overseas)

Material is physically available in an international warehouse or partner inventory.

Requires international transfer before final shipment
Typical fulfillment timeframe: 1–2 weeks
Delivery estimate shown reflects transfer and U.S. processing time

Final delivery timing depends on logistics and customs clearance where applicable.

Backordered

Material is not currently available as finished inventory but can be manufactured.

In many cases:

Product is 1–2 synthetic steps from existing building blocks
Required intermediates may already be in stock

Because precursor materials are often available, production timelines may be shorter than full custom synthesis.

Manufacturing location (U.S. or overseas lab) depends on:

Precursor availability
Production scheduling
Capacity

Estimated lead time is confirmed at order or quotation stage.

Made-to-Order

Material is produced specifically in response to a confirmed order.

This classification typically applies to:

Custom synthesis compounds
Larger-scale quantities beyond standard pack sizes
Special packaging or configuration requests

Made-to-order materials require defined production timelines and technical confirmation prior to execution.

Delivery Time Display

Product pages display estimated delivery timeframes based on:

For international customers, transit time from the U.S. shipping location to the final destination should be added to the displayed estimate.
