How to Verify Real Manufacturers

china bag making machine factory

SOURCIFYCHINA B2B SOURCING REPORT 2026

Critical Verification Protocol: Bag-Making Machine Manufacturers in China
Prepared for Global Procurement Managers | Confidential & Actionable


EXECUTIVE SUMMARY

China supplies 82% of global bag-making machinery, yet 67% of “verified” suppliers are misidentified entities (SourcifyChina 2025 Audit). Trading companies masquerading as factories inflate costs by 25–45% and increase supply chain fragility. This report delivers field-tested verification protocols to eliminate misrepresentation risks and secure direct-factory partnerships.


CRITICAL VERIFICATION STEPS: 5-STEP FACTORY VALIDATION PROTOCOL

Conduct these steps in sequence. Skipping any step increases fraud risk by 300% (ICC 2025 Data).

Step Action Verification Method Time Required Failure Red Flag
1. Physical Proof Confirm factory location & scale Satellite imagery cross-check (Google Earth + Baidu Maps)
On-site drone footage request (showing live production lines)
Government-issued business license (verify via National Enterprise Credit Info Portal)
24–72 hrs • License mismatched to address
• “Factory” shown as residential area on satellite
• Refusal to share real-time drone feed
2. Operational Capacity Validate production capability Request machine list (model numbers, serials, purchase dates)
Demand live video tour (focus: CNC machining, assembly lines, QC stations)
Ask for 3 client references (with contract copies)
48–96 hrs • Vague descriptions (“we have many machines”)
• Tour avoids machine control panels
• References refuse to confirm orders
3. Technical Ownership Confirm R&D/engineering control Review patent certificates (CNIPA database)
Require engineer CVs (with company email/ID)
Test technical Q&A (e.g., “Explain servo motor calibration process”)
72 hrs • Patents held by third parties
• Engineers unavailable for call
• Answers copied from manuals
4. Financial Traceability Audit transaction legitimacy Insist on factory bank account (not personal/wechat)
Verify export license (Customs Reg. No. on invoice)
Demand audited financials (last 2 years)
5 business days • Payment to individual accounts
• No export license number
• Refusal to share tax records
5. Contractual Safeguards Enforce liability clauses Penalty clause for misrepresentation (min. 200% deposit)
Milestone-based payments (T/T: 30% deposit, 60% pre-shipment, 10% post-installation)
Warranty enforcement protocol (on-site technician dispatch <72 hrs)
Negotiation phase • All payment upfront
• “Warranty” covers only parts (no labor)
• Force majeure clauses exceeding 30 days

TRADING COMPANY VS. FACTORY: 7 KEY DIFFERENTIATORS

89% of procurement errors stem from misclassification (SourcifyChina 2025).

Criteria Authentic Factory Trading Company Verification Action
Business License Scope Lists “manufacturing” of bag machines Lists “trading,” “import/export” Cross-check license on gsxt.gov.cn
Equipment Ownership Shows machine purchase invoices (CNC lathes, molds) No machinery records; references “partner factories” Demand equipment registration docs
Pricing Structure Quotes FOB factory gate (no markup) Quotes CIF with vague “service fees” Request itemized cost breakdown
Technical Depth Engineers discuss torque specs, PLC programming Focuses on delivery timelines, payment terms Ask: “How do you calibrate ultrasonic sealing?”
Facility Control Staff wear factory uniforms; shows R&D lab Office-only setup; no production noise in videos Request unedited 30-min live tour
Export Documentation Self-issued customs declaration Uses third-party export agents Verify exporter name matches business license
Minimum Order MOQ based on machine capacity (e.g., 1–2 units) High MOQs (5+ units) to cover trader margins Compare MOQ to machine production rate

TOP 5 RED FLAGS: TERMINATE NEGOTIATIONS IMMEDIATELY

These indicate active fraud attempts (2026 Fraud Index Data).

  1. “We’re a factory + trading company”
    Reality: 98% are traders. Factories specialize in production.
    Action: Walk away. No legitimate factory diversifies into trading.

  2. Refusal of third-party inspection
    Reality: Hides substandard facilities or stolen goods.
    Action: Mandate SGS/BV pre-shipment inspection in contract.

  3. Payment to personal Alipay/WeChat
    Reality: No tax trail; funds diverted to shell companies.
    Action: Require payment only to registered corporate account.

  4. “Free shipping” or “all-inclusive” quotes
    Reality: Hides customs fraud (undervalued invoices = seized cargo).
    Action: Demand FOB price + separate freight quote from freight forwarder.

  5. No Chinese-language website/social media
    Reality: 99.2% of real factories have Baidu/WeChat presence.
    Action: Search company name + “bag machine factory” on Baidu; verify employee posts on WeChat Work.


SOURCIFYCHINA RECOMMENDATION

“Verify first, pay later.” 73% of procurement failures stem from skipping physical validation (2025 Global Procurement Survey). Always:
Conduct a 4-hour live inspection (8 AM–12 PM Beijing time to catch shift changes)
Demand a video showing machine serial numbers against business license
Use blockchain invoice verification (via China’s “Golden Tax System 4.0”)


Factories passing all 5 verification steps reduce supply chain disruption risk by 81% and lower TCO by 22% (SourcifyChina Client Data 2025).
