Why verification matters before an IC purchase
In shortage sourcing and independent-channel procurement, a quote is only the first checkpoint. Buyers still need to confirm whether the offered lot matches the approved BOM, internal date-code rules, packaging requirements and incoming-inspection standards. A correct part number can still be rejected if the label, seal, package condition or lot information does not meet the customer's acceptance criteria.
This matters most for OEM, ODM and EMS teams buying production-critical ICs, EOL components or higher-value devices. Confirming these details before shipment gives purchasing, quality and production teams time to review the lot instead of discovering problems after the goods arrive.
What to check before confirming a purchase
| Check item | What to confirm | Procurement value |
|---|---|---|
| Full part number | Manufacturer, suffix, package, grade and lifecycle status | Reduces BOM mismatch and engineering rejection risk |
| Date code | Year code, lot range and customer acceptance window | Supports internal shelf-life and production rules |
| Packaging format | Reel, tray, tube, dry pack, MSL bag and seal condition | Helps verify handling status and shipment readiness |
| Label photos | Manufacturer label, lot, quantity, COO and barcode details | Allows pre-shipment review before PO release or shipment |
| Inspection support | Visual inspection, label review, X-Ray or third-party test if required | Adds control for shortage, EOL or high-value component lots |
RFQ information buyers should provide
A clear RFQ helps suppliers verify the right lot quickly. Instead of sending only a part number, include the required quantity, acceptable quantity range, target date code, package preference, delivery country and any photo or inspection requirements. If the project can accept substitute suffixes, state that separately so the quotation does not mix exact-match and alternative options.
- Required quantity and acceptable quantity range
- Target date code or minimum accepted date code
- Package format: reel, tray, tube, dry pack or original sealed package
- Delivery country and required shipment schedule
- Label photo, package photo, test report or third-party inspection requirement
Common issues found during pre-shipment review
Pre-shipment checks often catch practical issues that are easy to miss in a stock list: incomplete suffixes, mixed date codes, relabeled outer boxes, damaged moisture-barrier bags, missing tray labels or quantities that do not match the quoted packaging unit. None of these automatically means the lot is unusable, but each item should be reviewed before the buyer commits to production use.
For validated designs, buyers should also be careful with replacement suggestions. A related part number or similar suffix may still require engineering approval. If no alternatives are approved, the supplier should quote only the exact requested part number and package.
Procurement note: Listed stock should be treated as subject to final RFQ confirmation. Quantity, date code, packaging format, label condition and shipment schedule should be verified before order confirmation.
