Unauthorized Chinese subcontractor workshop operating at night behind a factory side door

Risk Intelligence · Tier-2 Exposure

Your goods may be produced in a workshop you've never seen.

The factory you audited is real. The factory making your order, often, is not. Hidden subcontracting is the single biggest blind spot in China sourcing — and the fastest way to fail CSDDD, UFLPA or a customs hold.

Why this happens

Capacity is finite. Your order isn't the priority.

When a Chinese factory wins an order it cannot fully fulfil, it does not turn it down. It sub-contracts the overflow — usually at night, usually to a workshop within 5km, almost never on the audit list.

Standard one-day audits cannot detect this. The day-shift line is your order. The night-shift line, in another building, is also your order — built by a third party with no compliance, no QC and no traceability.

When customs, a regulator, or your own brand audit finds it, the liability lands on the importer.

The forensic signals

Subcontracting leaves fingerprints. We look for all of them.

01

Capacity vs. Order Mismatch

  • Stated production capacity reconciled against your PO size and lead time
  • Worker count and shift pattern cross-checked against payroll database
  • Machinery utilisation rate calculated and benchmarked against industry norms
02

Night-Shift Surveillance

  • Discreet observation of after-hours truck movements in/out of the factory gate
  • Cross-reference of waybills against declared production schedule
  • Geotagged photo trail of any unannounced satellite workshop
03

Material Flow Forensics

  • Raw-material inflow vs. finished-goods outflow reconciliation
  • Serial-number traceability test on a random sample of finished units
  • Tooling and mould inventory check against your tooling registry
04

Sub-tier Mapping

  • All identified sub-tier workshops mapped, photographed, and registry-pulled
  • CSDDD-grade tier-2 supplier file delivered with worker headcount evidence
  • Risk-scored recommendation: accept, restrict, or terminate the supplier

How a sub-tier investigation runs

Three days of unannounced observation, one defensible map.

  1. Step 01

    Brief

    PO, lead time, declared capacity, factory address. We model expected production load.

  2. Step 02

    Day visit

    Floor walk, worker count, machinery audit, payroll reconciliation.

  3. Step 03

    Night observation

    Discreet 48-hour observation of gate traffic and after-hours activity.

  4. Step 04

    Sub-tier map

    Identified workshops visited, registry-pulled, photographed and risk-scored.
