The Problem

The Container Doesn’t Lie — The Factory Report Often Does

Most quality failures on imported construction materials are not bad luck. They are predictable — and almost all of them are visible at the factory before the goods are loaded.

Factory “self-inspection” is not inspection

Quality control reports written by the same team being paid for the order are not an independent check. They confirm the factory is comfortable shipping — nothing more.

Tolerances quietly drift mid-production

First samples are sharp, mid-run drifts a millimetre, end of run is off-spec. Without random sampling across the lot, the drift only shows up on site.

Damage happens at loading, not in transit

Crushed corners, scratched glass, dented profiles — most of it is loading day, not the ocean. Without loading supervision, the carrier inherits the blame.

Certificates that don’t match the goods

CE, SGS, ISO and mill certificates arrive as PDFs. Lot numbers, batch dates and material grades on the documents often don’t match what’s in the container.

Labels that don’t match the PO

Cartons labelled by factory SKU instead of your PO line. Site receipt becomes a treasure hunt and partial deliveries get blamed on “missing items”.

Defects you only see in daylight

Tile shading, glass distortion, finish variation — factory warehouse lighting hides what site daylight exposes. The wrong place to find that out is on site.

The JEES Approach

Independent. On-Site. Measured Against Your Spec.

Our inspectors visit the factory in person, work from a brief written off your order, and record measured values — not pass/fail ticks. Every defect is photographed in context, every certificate is reconciled to the goods.

The point of an inspection report is to let you make a confident sign-off, hold-and-rework, or reject decision without being on site yourself. That’s the only thing this service is built to do.

Measured against spec
Critical dimensions recorded with values, not ticks.
AQL random sampling
ISO 2859-1 Level II across the full production lot.
Finish & material checks
Coat thickness, glass composition, mill marks verified.
Certificates reconciled
CE, SGS, ISO and mill cert lots matched to the goods.
Loading supervised
Loading plan, lashing, container number and seal logged.
Photo evidence
Daylight-balanced photo set, defects shown in context.
How It Works

From PO to Sealed Container — Twelve Inspection Steps

The same twelve-step inspection workflow runs on every order. The flow below shows how your PO splits into measured checks, evidence and documents, then reconverges into a single signed report.

On-site visit
Factory floor
DimensionsFinishFunctionPackagingDocuments
One report
Pass · Hold · Reject

Your PO splits into five check tracks at the factory — dimensions, finish, function, packaging and documents — then reconverges into one signed inspection report with a clear decision per line.

  1. Step01

    PO & spec submitted

    Send the PO, spec sheet, drawings and packing list. We build the inspection brief directly from your documents — no template checklist.

  2. Step02

    Inspection brief written

    Critical, major and minor defect classes defined in writing for this specific order, with measurable acceptance criteria per characteristic.

  3. Step03

    Visit booked with factory

    On-site visit scheduled with the factory at the agreed production stage — during, end-of-line, or pre-shipment depending on your QC plan.

  4. Step04

    Dimensional checks

    Calipers, tapes and gauges against the spec. Every critical dimension recorded with the measured value, not just pass/fail.

  5. Step05

    Finish & material verification

    Powder coat thickness, anodising film, glass composition, mill marks and surface finish checked against the order specification.

  6. Step06

    Function tests

    Where applicable — hardware operation, sliding force, latch engagement, drainage paths, electrical continuity — tested on sampled units.

  7. Step07

    Packaging audit

    Carton strength, corner protection, edge foam, stretch wrap, palletisation and stacking checked against destination port handling.

  8. Step08

    Documents cross-check

    CE, SGS, ISO, mill and test certificates cross-checked: lot number, batch date and material grade matched to the goods being inspected.

  9. Step09

    AQL sampling

    Random sampling per ISO 2859-1 Level II with the AQL agreed for the order. Defects classified critical, major or minor and counted against acceptance limits.

  10. Step10

    Photo evidence captured

    Every defect photographed in context — measurement in frame where relevant — so the report is reviewable without being on site.

  11. Step11

    Loading supervision

    Container loading attended. Loading plan followed, lashing verified, container number and seal recorded, full loading photo set captured.

  12. Step12

    Report delivered in 24h

    Inspection report delivered within 24 hours of the visit — pass / hold / reject decision per spec line, with all photos and certificates attached.
