Independent electronic component distributionChina supply. International business.

Confidence starts
with a closer look.

Independent third-party inspection is part of our lot-release process. We agree the methods, sampling and acceptance requirements for the proposed order.

Discuss your inspection requirements

The specification is the starting point.

We source new, unused original components. Inspection supports a buying decision when it is tied to a clear, agreed requirement.

Before ordering, tell us which conditions are mandatory: exact ordering code, date-code range, lot consistency, packaging, traceability documents and any application-specific quality requirements.

Available evidence and test coverage vary by lot. A source description, a photograph or a passed visual check alone is not a substitute for complete product qualification.

Check the lot.
Not just the label.

These details establish what is being offered and what needs to be verified.

  • IdentityFull MPN, manufacturer, package and marking consistency.
  • Lot detailsQuantity, date codes, mixed-lot status and the scope of available traceability.
  • ConditionPackaging, seal status, visible condition and available storage information.
  • DocumentationSource documents that can be shared, with their scope and limitations made clear.

Agree the inspection
before the order moves.

Every supplied lot is subject to independent third-party inspection under the agreed order conditions.

The plan identifies the laboratory, test methods, sample quantities, acceptance criteria, report requirements, fees and expected timing. Sampling depends on the method and the order; it does not mean every piece receives every test.

Inspection and any application qualification are separate decisions. Destructive testing, advanced analysis and extended electrical tests require a specific scope.

How ordering and release work

Different checks.
Different questions answered.

Methods below illustrate an inspection discussion. They are not a promise that every order includes every test.

MethodWhat it can help assessWhat it does not establish alone
External visual inspectionMarkings, package surface, terminals and visible inconsistencies.Complete electrical operation, provenance or service life.
X-ray inspectionInternal construction and consistency within the tested sample.All material characteristics or full functional performance.
Electrical testingSpecified parameters under the agreed test conditions.Performance beyond the tested parameters and conditions.
Additional analysisSpecific questions that need targeted, sometimes destructive, methods.A universal certification of all pieces in a lot.

Read beyond
the result line.

A useful report connects the tested samples to the method, findings and agreed acceptance criteria.

Match the identity

Check the MPN, lot reference and sample identity against the order under review.

Read the sample counts

This excerpt records different quantities for different checks, including five, three and one piece. It does not describe every-piece testing.

Keep the observations visible

The example notes minor surface contamination on one inspected piece and records the external visual result as acceptable. That observation remains part of the report.

Confirm the release decision

An acceptable result for one inspection scope does not automatically establish full functionality or authorize shipment.

Choose the laboratory
and the scope together.

You may propose a laboratory and discuss the tests needed for the order.

These external laboratory references help you explore services. They do not imply that ICstoq owns the facilities, holds their accreditation or has an exclusive partnership.

Capability, location, accreditation scope, availability and reporting requirements must be checked for the chosen test plan.

A finding needs a decision.

If inspection raises a question, the next step is review against the order’s acceptance criteria.

Where the agreed release conditions are not met, shipment remains on hold while the finding, possible further testing and next steps are discussed. The response depends on the evidence and the agreed commercial terms.

Does inspection mean every piece is tested?

No. Inspection is arranged for each lot, with method-specific sampling and scope agreed for the order. Some methods may be destructive.

Can I request additional or customer-specified tests?

Yes. Include the requested method, laboratory, sampling and acceptance criteria in your enquiry. Capability, cost and timing need to be confirmed before commitment.

Is a sample report evidence for the part I am buying?

No. The public excerpt explains how reports are read. Your order needs evidence tied to its own part, lot and inspection plan.

Make your quality
requirements part of the RFQ.

Start with the part number and quantity. Add your mandatory date-code, packaging, traceability and inspection requirements if they are already defined. Detailed order evidence can be reviewed as the proposed lot is established.
