China FAT/PSI defect patterns: anonymised pre-release QC findings, 2023–2025
What this sample is — and is not
This is an anonymised review of an internal inspection/QC record set: 96 China-origin inspection packages from 1 January 2023 to 31 December 2025, built from internal inspection correspondence, factory acceptance test (FAT) reports, pre-shipment inspection (PSI) reports and document-review records, across international, African and EU-GMP project contexts. One record means one order/inspection package — if an order had both a FAT and a PSI it is still counted once, and the “stage caught” field records the first stage where a material defect, hold or corrective-action trigger surfaced.
A defect or hold, for this analysis, means a recorded issue that required correction, additional evidence, waiver, rework, retest, replacement, or quantity/packing/spares reconciliation before final release or shipment. The sample excludes pure logistics correspondence, post-delivery warranty issues, duplicate report revisions, informal notes with no inspection outcome, and any record whose equipment family, stage or disposition could not be resolved without identifying the order.

Equipment families
Families are deliberately broad to preserve anonymity. No brand, model, factory, site, city, project or supplier detail appears anywhere in this analysis.
| Equipment family | Description | N |
|---|---|---|
| Cleanroom / facility systems | Cleanroom packages, HVAC-related systems, facility utilities, controlled-environment support | 30 |

| Energy / electrical systems | Power, backup, distribution, electrical control or energy-support equipment | 22 |
| Healthcare / lab equipment | Healthcare, laboratory, diagnostic, technical-room or clinical-support equipment | 20 |
| Total | 96 |
How issues were classified
Issues were coded against a fixed, multi-select taxonomy decided before the records were read. One inspection package can carry more than one issue.
| Category | Coding definition |
|---|---|
| Documentation gap | Missing, incomplete, outdated, inconsistent or unapproved documentation — manuals, drawings, FAT packs, calibration evidence, inspection records, revision-control evidence |
| Certification mismatch | Certificate, declaration, calibration certificate, compliance reference, serial number, standard or material certificate does not match the order/specification |
| Packing / marking | Non-conforming packing, crate labelling, shipping marks, preservation, protection, orientation, handling marks or export-marking evidence |
| Dimensional / build non-conformity | Physical construction, dimensions, finish, assembly, materials, workmanship or configuration not matching the order/specification |
| Functional-test failure | Performance, safety, interlock, control, alarm, capacity, stability or acceptance-test failure during FAT or other functional verification |
| Missing spares | Contracted spares, accessories, tools, consumables, filters, gaskets, cables or kits missing or not evidenced |
| Quantity discrepancy | Ordered versus inspected/shipped quantity discrepancy |
Findings by defect category
Denominator: 96 inspection packages. Categories are multi-select, so the shares do not add up to 100% — they show how often each issue type appeared, not mutually exclusive root causes.
| Rank | Defect / hold category | Count | Share |
|---|---|---|---|
| 1 | Documentation gap | 29 | 30% |
| 2 | Certification mismatch | 21 | 22% |
| 3 | Packing / marking | 18 | 19% |
| 4 | Dimensional / build non-conformity | 16 | 17% |
| 5 | Functional-test failure | 13 | 14% |
| 6 | Missing spares | 12 | 13% |
| 7 | Quantity discrepancy | 10 | 10% |
Headline finding. Documentation gaps were the most common pre-release defect/hold category, appearing in 29 of 96 inspection packages — 30% of the sample.
Safer interpretation. The pattern suggests pre-release inspection value is not limited to finding physical defects. In this sample, evidence quality, certificate consistency, packing/marking and release-pack completeness were frequent blockers before shipment — the kinds of issue a paperwork-light inspection would miss.
Disposition outcomes
Denominator: 96 inspection packages.
| Disposition | Definition | Count | Share |
|---|---|---|---|
| Released | Released without material corrective action recorded | 49 | 51% |
| Conditionally released | Release dependent on additional evidence, waiver, correction or close-out confirmation | 27 | 28% |
| Held | Not released at inspection close; correction or evidence required first | 10 | 10% |
| Rework / retest | Physical rework, replacement, adjustment or repeat test required before release | 10 | 10% |
In this sample, 47 of 96 inspection packages — 49% — required some form of corrective action, additional evidence, hold resolution, rework or retest before final release.
Findings by equipment family
| Equipment family | N | Required corrective action | Share |
|---|---|---|---|
| Cleanroom / facility systems | 30 | 17 | 57% |
| Process equipment | 24 | 10 | 42% |
| Energy / electrical systems | 22 | 10 | 45% |
| Healthcare / lab equipment | 20 | 10 | 50% |
| Total | 96 | 47 | 49% |
The family-level pattern should be read cautiously because the sample is intentionally broad and anonymised. Cleanroom/facility systems showed the highest corrective-action rate in this cut, but the more defensible finding is qualitative: different equipment families tended to fail in different ways. Cleanroom/facility packages skewed toward documentation, certification and packing evidence; process equipment more often involved build or functional-test observations; energy/electrical packages were commonly affected by certification and marking checks; healthcare/lab packages often required documentation, spares or quantity reconciliation. Family-by-category breakdowns are kept qualitative here because the per-cell counts are too small to publish without risking re-identification.
Where issues first surface
Denominator: the 47 inspection packages that required corrective action.
| First stage where the issue surfaced | Count | Share |
|---|---|---|
| Document review | 20 | 43% |
| Factory acceptance test (FAT) | 17 | 36% |
| Pre-shipment inspection (PSI) | 10 | 21% |
In this sample, 43% of corrective-action cases first surfaced during document review — before or alongside physical inspection activity. FAT accounted for 36% and PSI for 21%. The practical buyer takeaway: document review should not be treated as an administrative afterthought, because a substantial share of pre-release blockers is visible before the inspector reaches final shipment checks.
What it means for buyers
| Buyer action | Why it matters |
|---|---|
| Define the release pack before production is complete | Documentation and certification gaps are often visible before shipment pressure begins |
| Treat FAT and PSI as linked controls | FAT may confirm function while PSI still catches packing, marking, quantity or spares issues |
| Specify certificates and revision evidence in the PO/specification | Certification mismatches are easier to prevent than to resolve once goods are ready |
| Build time for close-out into the schedule | Conditional release, hold resolution, rework and retest can delay shipment |
| Require evidence-based close-out | Photos, revised documents, retest records and corrected packing lists reduce ambiguity |
Method note. This analysis is based on anonymised internal inspection/QC records. No client, supplier, factory, project, site, brand, model or individual names are included, and shares are published only where the underlying count is large enough to publish without identifying an order.
Frequently asked questions
What was the most common pre-release issue in this sample?
Documentation gaps — missing, incomplete, outdated, inconsistent or unapproved documentation. They were recorded in 29 of the 96 inspection packages, or 30% of the sample, ahead of certification mismatches (22%) and packing/marking issues (19%). Because issues are multi-select, one package can appear in more than one category.
Does this mean equipment from China is usually defective?
No. This is an anonymised internal inspection/QC record set, not a market-wide benchmark. It only describes the 96 packages in the sample, all of which already had a documented inspection trail. It should not be read as a country-level quality rate, a supplier ranking, or a statement about equipment that was never inspected.
How large was the sample and what did it cover?
Ninety-six inspection packages — one record per order — from 1 January 2023 to 31 December 2025, drawn from internal inspection correspondence, FAT reports, PSI reports and document-review records for China-origin inspections in international, African and EU-GMP project contexts. No row-level data is published.
Where do pre-release issues first surface?
Among the 47 packages that required corrective action, 43% of issues first surfaced during document review, 36% during the factory acceptance test (FAT), and 21% during pre-shipment inspection (PSI). A substantial share of blockers is therefore visible before the inspector reaches final shipment checks.
What share of inspections required corrective action before release?
47 of 96 packages, or 49%. Of the 96, 49 were released without material corrective action, 27 were conditionally released pending evidence or close-out, 10 were held, and 10 required rework or retest before release.
How Sinospect uses the same inspection discipline
The inspection and document-control discipline used to build this analysis is the same one Sinospect applies on live orders: helping buyers define, witness and close out FAT and PSI requirements before equipment is released for shipment from China. The field sequence behind the FAT side is the factory acceptance test checklist, and witnessed execution sits in Sinospect’s factory acceptance testing in China service. If you have a live file — equipment list, specification, certificate package or a proposed inspection scope — submit it for review before the supplier offers the goods for shipment.
Planning FAT or PSI for a China order?
Send the equipment list, specification and certificate package. Sinospect responds with the inspection scope to write into the order, the documentation to require, and what should be verified before release rather than after the goods are ready.
