A · BASELINE
Manufacturer / authorized route
Used only when the relevant manufacturer or distributor relationship can be established for that quoted source. Availability, price and transaction documents still require confirmation.
Source & Quality
State what is known. Keep what is not known visible.
Source disclosure and receiving checks reduce avoidable errors, but they are not a blanket authenticity guarantee. The current public scope is deliberately narrow.
Source categories
Source status belongs to a specific quote—not to a marketing slogan.
I · DISCLOSED
Independent market source
Considered case by case. The supplier identity, stated lot information, available evidence and unresolved limitations must be clear before customer approval.
R · NO QUOTE
Rejected or outside scope
Used when the source explanation is inconsistent, documents appear false, relabelling is requested, the end use is restricted or the risk cannot be brought within the current capability.
Current capability · L1
Receiving and visible-consistency checks.
These are the checks currently described as standard website capability.
What we check
- Quantity against the approved order
- Packaging label information
- Complete MPN and manufacturer marking
- Package form: reel, tray, tube or cut tape
- Stated date/lot code and obvious batch inconsistencies
- Visible oxidation, sanding, remarking or packaging damage
- Photographic record of received goods
What this cannot prove
- Internal die identity or authenticity
- Complete electrical and functional performance
- Solderability under the customer's production conditions
- Whether sophisticated alteration is present
- That every unit in a lot has identical condition
- Compliance with an application-specific qualification standard
Current capability boundary
If the stated checks are not enough, the answer is not stronger wording.
A high-value, obsolete or independent-market component may require evidence beyond the current public process. We will identify that gap before accepting the work rather than imply that an unavailable assurance step has been completed.
When the required risk control exceeds the checks listed on this page, the current outcome is to pause, revise the sourcing route or decline the request.
Current exclusions
Requests we do not accept at this stage.
-
Military, police, aerospace or nuclear end use
-
Medical life-support or automotive safety-critical applications
-
Restricted parties, sanctioned destinations or concealed end users
-
Relabelling, falsified documents, false origin declarations or export-control evasion
-
Transactions where the payer, buyer, consignee or end user cannot be reasonably explained

Source preference, required documents, intended application and acceptable residual risk should be part of the RFQ—not added after purchase.
