How catalog discovery, supplier responses and final quotations are separated.
No. A catalog match confirms the product record but does not identify the fulfilment source or reserve material. The requested quantity may be confirmed from Chip-seek's warehouse or a reviewed sourcing channel before quotation.
It records when the storefront catalog lookup was performed. It is not a supplier inventory timestamp or a promise of availability.
Quantity, price, MOQ and lead time can change. A fresh check is required when the quotation expires or the requirement changes.
Submit the complete manufacturer part number, quantity and technical context through RFQ or EOL sourcing for manual review.
