Unauthorized Subcontracting: How to Keep Your Knitwear Where You Placed It

By YZR Sweaters · 2026-11

You audited the factory, you approved the sample, and for the first three weeks everything was normal. Then the defect profile of your order changes character — not worse, exactly, but different: a different linking style, buttons attached differently, measurement drift in places that were previously rock solid. We hear this story from buyers several times a year, and it usually ends with an uncomfortable discovery: part of the order was never made in the factory they chose. Here is why it happens, how to see it, and how to make it structurally difficult.

Why factories subcontract without telling you

Motive is rarely sinister — it is arithmetic. The common drivers, all of which we see each peak season:

• Capacity peaks. A factory takes on more capacity bookings than its machines can knit in the window, trusting that some orders will cancel or slip. When none do, the gap gets filled at a smaller workshop down the road.
• Seasonal squeeze. The weeks before Chinese New Year are the classic pressure point — every buyer wants goods shipped before the shutdown, and overflow is everywhere.
• Price pressure. If the buyer negotiated to a margin that the factory's own cost base cannot honour, the only way to run the order profitably is a cheaper workshop — often one without the audited compliance, machinery or quality systems that justified your selection.
• Process specialisation. Embroidery, washing or certain finishes are legitimately outsourced by most factories — the problem is only when this normal practice is hidden rather than declared.

The industry learned the hard end of this lesson in 2013, when the Rana Plaza collapse killed garment workers producing for brands that did not know their orders were running in that building. Since then, serious buyers treat unauthorized subcontracting as a compliance issue, not merely a quality annoyance — and so should you, whatever your size.

The red flags that actually work

Every confirmed case we have been shown had at least two of these signals before anyone found the physical evidence:

• Quality character shifts mid-order. Not a decline — a change of signature. Linking tension, button attachment style, necktape finishing and measurement distribution suddenly look like a different set of hands, because they are. Compare against your gold seal samples and early inline inspection records, not just the spec.
• Inspection access gets difficult. The factory stalls on inspection dates, offers only guided windows, or the inspector is kept away from particular floors or shifts. Legitimate factories compete to show you their line running; evasive scheduling is a signal.
• Production photos stop matching reality. Ask for dated photos of the order on machines. Look past the garments at the background: machine brands and gauge counts, floor layout, lighting. If the machine park in the photos does not match what you saw at audit, you are looking at someone else's floor.
• Paperwork inconsistencies. Yarn lot numbers on cone labels that do not match the yarn purchasing records for your order; cartons arriving with two different handwriting styles or tape; packing lists whose carton-count sequence has gaps.
• Capacity maths that never closed. If you ordered 20,000 pieces at a gauge the factory has 30 machines to run, in a window that allows 12,000 — the order was going to be subcontracted from the day it was confirmed. Do this calculation at vetting, not after the fact.
• Too-good pricing. A quote materially below the credible cost of production is not a bargain; it is a promise someone intends to fulfil somewhere cheaper.

The three-layer defence

Layer one — the contract. Your supply contract should require written authorization for any production outside the named facility, an obligation to declare any subcontractors used for specified processes (with names and addresses), and the buyer's right to audit or inspect those premises to the same standard. Attach consequences with teeth: rejection rights for undeclared production and cost of re-inspection or re-shipping on the factory's account. A clause nobody enforces still helps — it converts a "misunderstanding" into a breach.

Layer two — the audit trail. Make subcontracting visible instead of invisible:

• Book pre-shipment inspections together with at least one unannounced or short-notice inline check during knitting, when there is nothing yet to parade around.
• Require yarn traceability: lot numbers from the spinning mill through dyeing to the cones on your machines, cross-checked against the bill of materials. Grey-market yarn arriving in unlabelled bags is the raw material of quiet outsourcing.
• Use numbered security seals on cartons after final inspection, with the seal series recorded in the inspection report. It protects the goods and closes the classic gap where finished cartons from a second site merge with yours.
• Engage third-party inspectors who physically walk the production floor, not just the finished-goods warehouse.

Layer three — the relationship. Factories subcontract secretly when the honest alternatives hurt more. If you change your order late and demand the same ship date, you have created the exact conditions for overflow. Keep your order changes disciplined, book capacity honestly, and pay prices that are viable at the quality you demand. Then there is nothing to hide, and the contract clause becomes a formality rather than a tripwire.

What to do when you find it

First, verify before you escalate — the "subcontracting" sometimes turns out to be a declared process partner you forgot was in the supply chain map. If it is real and undeclared: quarantine affected goods, re-inspect against seal samples with defect focus on the change of signature, decide per carton rather than per order, and put the commercial conversation in writing. The strongest buyers treat a first confirmed case as a correctable breach with a formal corrective action plan; a second case ends the relationship, because a supplier who has been caught once and does it again is not managing risk — he is managing you. Reassess the programme through the scorecard and adjust risk planning accordingly.

At YZR Sweaters we knit in our own Dongguan workshop, and where a process genuinely runs outside our floor — as some finishing and embellishment does for most factories in this trade — it is declared in the quotation, listed by name, and open to your inspection on the same terms as ours. We would rather quote the honest capacity date than book an order we cannot knit ourselves. If transparency on where your garments are actually made is part of your brief, make it part of ours: tell us the programme and the compliance standard.
