Cashmere Factory Audit Checklist: 12 Verification Points for B2B Buyers (2026)

Auditing a cashmere factory before your first USD 30K+ order is non-negotiable. The cheapest factory quote often hides the highest risk: fiber sourced from undisclosed origins, untrained workers, missing social compliance certifications, or production capacity that can’t actually deliver what was promised. We’ve been on both sides of factory audits — buyers who came to our 38,000 m² Ordos facility with 30-page questionnaires, and buyers who never visited and learned the hard way.

This checklist is the practical subset of what B2B cashmere buyers should verify. It’s not the full ISO 9001 audit (those take 3 days and cost USD 5,000+), but it’s the 12 points that catch 90% of the cashmere-specific risks. Use it before your first order, again when renewing annual contracts, and once more if you notice quality drift.

1. Fiber Origin Documentation

Ask for the past 12 months of fiber purchase records: combing certificates, combing station names, dates, and quantities. Premium cashmere comes from Alashan, Ordos, or Bayannur in Inner Mongolia; mid-grade from Liaoning, Qinghai, or Gansu; lower-grade from Mongolia or Iran. The documents should show that fiber was sourced from named regions with declared combing stations — not generic “China cashmere” with no provenance.

Red flag: Factory cannot produce combing certificates for the fiber grades they’re claiming (e.g., claims 14.5μm premium but only has 16μm documentation). Why it matters: Fiber grade is the single biggest cost driver — premium 14.5μm fiber costs USD 80-120/kg vs USD 40-60/kg for 16μm. If the factory is pricing a “premium” sweater at the “16μm” rate, they’re cutting fiber.

2. Dehairing Line Inspection

Cashmere raw fiber arrives mixed with coarse guard hair (sometimes 50% of the raw weight). The dehairing process separates fine underdown from guard hair using mechanical rollers. A well-run dehairing line has visible equipment (Italian or Chinese dehairing machines, named make/model), clean working environment, and QC checkpoints.

What to look for: Walk the dehairing floor. The fiber should look uniformly fine and clean. Ask to see the dehairing machine nameplate. Red flag: Fiber looks coarse or has visible guard hair contamination — means the line is poorly calibrated or fiber was never properly dehaired. Why it matters: Poor dehairing = itchy, pilling-prone garments that fail your customer’s quality expectations after 2-3 wears.

3. Spinning Mill Connection

Cashmere yarn production requires either in-house spinning or a long-term contract with a spinning mill. Ask whether spinning is in-house or outsourced, and if outsourced, ask for the spinning mill’s name and visit authorization. Most Chinese cashmere garment factories are not spinners — they buy yarn from regional spinning mills (Inner Mongolia ERDOS Group’s spinning division, Hubei Chunfeng, Zhejiang Xinao, etc.).

Red flag: Factory claims to spin in-house but cannot show spinning equipment or claims fiber is “directly spun” with no mill reference. Why it matters: The spinning mill controls yarn quality, twist, ply evenness, and pilling resistance. If the mill is unknown or low-quality, the garment quality is at risk regardless of the cut-and-sew facility’s standards.

4. Knitting Machine Inventory

Walk the knitting floor and count the machines. German STOLL and Japanese Shima Seiki machines are the industry standard for fully-fashioned cashmere knitwear. Chinese-made machines (e.g., Longxing, Wuxi) are acceptable for basic stockinette but struggle with complex stitch structures.

What to look for: At least 10-15 knitting machines for a mid-sized factory (50-200 workers). Modern CNC machines with HMI controls, not older mechanical cam machines. Red flag: Factory has fewer than 8 knitting machines or all machines look older than 10 years. Why it matters: Machine capacity determines whether the factory can deliver your 1,000-piece order in the 8-10 week production window you need.

5. Cut-and-Sew Workshop

For garment production, the cut-and-sew workshop is where most labor risk hides. Check: workstation spacing (Chinese labor law requires minimum 1.2 m² per worker), lighting, ventilation, fire extinguishers, electrical safety, and emergency exits.

Red flag: Crowded workstations, blocked exits, missing fire safety equipment, visible child workers. Why it matters: Beyond ethics, crowded or unsafe workshops correlate with higher defect rates (workers under pressure make more mistakes), social compliance audit failures (which your downstream brand needs to pass), and reputational risk if a fire or injury makes the news.

6. Working Hours and Payroll Records

Ask for the past 3 months of working hour logs and payroll records (anonymized). Chinese labor law caps weekly hours at 44 regular + 12 overtime. Overtime pay is 1.5x (weekdays), 2x (weekends), 3x (statutory holidays).

Red flag: Average weekly hours consistently above 60, no overtime records, or worker interviews suggesting they earn less than the local minimum wage (currently RMB 2,400/month in Inner Mongolia urban areas, RMB 1,800-2,000 in surrounding rural areas). Why it matters: Excessive overtime is a strong predictor of quality drift (tired workers make mistakes), and a major red flag for social compliance audits your downstream brand may require.

7. Water and Wastewater Management

Cashmere dehairing, washing, and dyeing all use significant water. The factory should have a wastewater treatment system, often visible as a small treatment plant on site. Ask for the wastewater discharge permit (排污许可证) issued by the local environmental authority. Permits expire annually — request a copy of the current one.

Red flag: No visible wastewater treatment, discharge into rivers without permits, or expired permits. Why it matters: Beyond environmental ethics, an unpermitted factory can be shut down by the Chinese government with 24-48 hours notice — your production line stops mid-order with no recourse.

8. Electricity and Boiler Systems

Most cashmere processing requires steam (for dyeing, finishing). The factory needs reliable electricity (typically a 250-500 kVA transformer) and either a coal-fired, gas-fired, or biomass boiler. Coal boilers are increasingly restricted in Chinese cities — gas or biomass is the modern standard.

Red flag: Factory still uses coal boilers in a city that has banned them (most Tier 1-3 cities since 2020), or electricity comes from a portable diesel generator (signals unreliable grid or excessive load shedding). Why it matters: Coal boilers in restricted zones get shut down mid-production. Diesel generators signal the factory can’t run at full capacity during winter peak loads.

9. Quality Control Lab

A serious cashmere factory has a small in-house QC lab with: microscope or fiber diameter analyzer (for micron measurement), pilling tester (Martindale or ICI), color fastness testing equipment, and a hand-feel reference sample library. The lab should be staffed by 2-4 trained technicians.

Red flag: No in-house lab, or lab equipment looks 15+ years old and hasn’t been calibrated recently. Why it matters: If the factory can’t measure fiber fineness themselves, they’re guessing at fiber grade claims. Without pilling testing, they can’t guarantee the garment will survive 30+ wears. You end up doing their QC for them.

10. Previous Client References

Ask for 3-5 client references: brand names, contact emails, and approximate order volumes. Most factories will have 2-3 brands willing to be references and 1-2 that prefer anonymity. Ask the references about: order consistency, defect rates, on-time delivery, and how the factory handles quality issues.

Red flag: Factory can’t name any client references, all references are >5 years old, or references are all small (under USD 20K) when the factory claims to handle USD 100K+ orders. Why it matters: References are the best predictor of how the factory will treat you. A factory that delivered on time for 5 similar buyers will likely deliver on time for you.

11. Social Compliance Certifications

Check for the certifications your downstream brand requires. Common ones for cashmere:

• BSCI / Sedex SMETA — social compliance audits (working hours, wages, safety). Required by most EU brands.
• SA8000 — more rigorous social compliance standard.
• OEKO-TEX Standard 100 — product safety (no harmful chemicals). Critical for EU/US retail.
• GOTS — for organic cashmere (rare, since most cashmere isn’t grown organically).
• RWS (Responsible Wool Standard) — animal welfare for fiber. Increasingly requested.
• Good Cashmere Standard — combines animal welfare, social compliance, and traceability.

Red flag: Factory claims “all certifications available” but can’t show certificates, or has only one outdated certification (3+ years old). Why it matters: Downstream brands increasingly require these certifications. Without them, you can’t sell into EU retail, US mid-market brands, or any brand with a published sustainability policy.

12. Remote Verification Options

If traveling to China isn’t feasible (cost, time, visa), remote verification is acceptable if you use multiple channels:

• Live video tour: 30-45 minute WhatsApp/Zoom walk-through, with you or your agent asking questions in real time. Most legitimate factories accommodate this within 1-2 days notice.
• Third-party inspection: Hire SGS, Bureau Veritas, or Intertek for a pre-shipment inspection (PSI). Cost is USD 250-500 per man-day; 2 days is sufficient for a first-order audit.
• Document verification: Ask for scanned copies of business license, export license, social compliance certificate, combing station records, and recent client PO confirmations. Cross-check the business license with the Chinese National Enterprise Credit Information Publicity System (gsxt.gov.cn) — it’s free and shows registration date, legal representative, registered capital, and any past violations.
• Sample order: Place a 50-piece sample order at standard pricing and observe: on-time delivery, quality match, communication responsiveness, documentation completeness. A factory that handles a 50-piece sample well will likely handle 1,000 pieces similarly.

Red flag: Factory refuses any remote verification, requires payment before any document is shared, or only communicates via WeChat (not email). Why it matters: Refusal to verify signals risk. A legitimate factory welcomes scrutiny — it gives them a competitive edge over factories that won’t open their doors.

Putting It Together: A 2-Day Audit Plan

For buyers serious about a USD 50K+ first order, a 2-day on-site audit typically covers:

• Day 1 morning: Fiber storage, dehairing line, spinning floor walk-through.
• Day 1 afternoon: Knitting floor, cut-and-sew workshop, QC lab, worker interview.
• Day 2 morning: Utility systems (boiler, wastewater, electricity), management interview, document review.
• Day 2 afternoon: Reference calls, sample inspection, contract discussion.

Two auditors (one quality specialist, one social compliance specialist) is ideal. Cost is roughly USD 1,500-3,000 per auditor including travel, which is small relative to the risk of a bad USD 50K order.
