International wire transfers sent via SWIFT cannot be reversed once credited to an overseas account. When an importer wires money to a new supplier, they are taking an unsecured commercial credit risk. This guide outlines the rigorous, sequential due diligence protocol professional procurement teams use to verify factories, eliminate intermediary fraud, and protect capital before initiating any financial transaction.
Phase 1: Legal Entity & Corporate Verification
Before requesting product samples or negotiating pricing, verify that the counterparty is a legally registered corporate entity with valid export authorizations.
1. Obtain and Validate the Business License
Request an unedited copy of the supplier's domestic business registration certificate:
- China: Unified Social Credit Code (USCC) on the Business License (营业执照). Cross-reference this number against the National Enterprise Credit Information Publicity System (GSXT). Verify registered capital, date of establishment, and legal business scope. If the scope reads only "trading," "consulting," or "commercial agency," you are dealing with a broker, not the manufacturing plant.
- Vietnam: Enterprise Registration Certificate (ERC) issued by the Department of Planning and Investment (DPI). Cross-reference the enterprise code on the National Business Registration Portal (dangkykinhdoanh.gov.vn).
- India: Corporate Identification Number (CIN), Goods and Services Tax Identification Number (GSTIN), and Import Export Code (IEC) issued by the Directorate General of Foreign Trade (DGFT).
2. Cross-Check the Corporate Bank Account Details
The registered beneficiary name on the proforma invoice bank wire instructions must match the exact legal corporate entity name on their business license. Never transfer funds to:
- An individual person's name (e.g., "Mr. Chen" or "Ms. Nguyen").
- An offshore entity in an unrelated jurisdiction (e.g., a British Virgin Islands or Hong Kong shell company when ordering from a factory in mainland Vietnam or Ningbo), unless explicitly backed by audited parent-subsidiary governance documentation.
- A third-party "payment agent" or unverified personal peer-to-peer account.
Phase 2: Factory Capability & Production Auditing
Trading companies frequently download high-resolution photos of third-party factories and present themselves as the manufacturer. You must prove the facility actually produces your product.
1. Unannounced Virtual Video Audit
Schedule a video walk-through during normal working hours in the supplier's local time zone:
- Request that the sales representative walk onto the manufacturing floor, camera live.
- Ask to see raw material staging areas, active assembly lines, tooling storage, and the quality testing laboratory.
- Observe the workers: Are they wearing safety equipment? Are production schedules visibly posted? Are quality control stations active?
2. Professional Third-Party Factory Audits
For orders exceeding $10,000, commission an independent third-party inspection agency (e.g. SGS, Bureau Veritas, TUV Rheinland, or QIMA) to perform an on-site Factory Quality Audit. For a standard fee of $300 to $400, an inspector visits the physical facility and delivers a comprehensive 20-page report verifying:
- Physical plant existence, land registry, and number of full-time employees.
- Installed machinery, monthly production capacity, and maintenance logs.
- ISO 9001 quality management implementation.
- Working conditions, child labor compliance, and fire safety systems.
Phase 3: Sample Evaluation and Technical Verification
Never place a production order based solely on digital product renderings or catalog specifications.
- Pre-Production Golden Sample: Have the factory produce a physical sample incorporating the exact materials, tolerances, Pantone colors, and custom packaging you specified in your RFQ.
- Stress and Compliance Testing: Submit the golden sample to an accredited domestic testing lab to verify regulatory compliance (e.g. FDA food-contact standards, RoHS for electronics, or California Prop 65 chemical thresholds).
- Retain Counter-Samples: Retain two identical samples. Sign and date one and courier it back to the factory as the approved standard; keep the second locked in your office to serve as the baseline during pre-shipment inspections.
Phase 4: Structuring Safe Commercial Payment Terms
| Payment Structure | Risk Profile | When to Use |
|---|---|---|
| 100% Upfront T/T Wire | Severe (Unacceptable) | Never for commercial production. Acceptable only for low-cost samples under $300. |
| 30% Deposit / 70% Balance Post-Inspection | Balanced Commercial Standard | The standard global practice for custom manufacturing. 30% begins raw material procurement; 70% is wired only after passing third-party pre-shipment inspection and receiving the non-negotiable Bill of Lading copy. |
| Documentary Letter of Credit (L/C) | High Buyer Protection | Orders exceeding $50,000 to $100,000. Payment is released by the bank only when compliant shipping, inspection, and customs documents are presented. |
| Trade Assurance / Escrow | Moderate Protection | B2B marketplace orders under $15,000. Funds are held in escrow until dispatch verification. |
Top 6 Sourcing Red Flags to Watch Out For
- Last-Minute Bank Account Changes: You receive an urgent email stating: "Our corporate bank account is undergoing audit. Please wire the 30% deposit to our overseas director's account." This is almost invariably a Business Email Compromise (BEC) hack. Always verify wire details over a known, verified phone number before sending funds.
- Reluctance to Accept Third-Party Inspection: If a supplier claims "Our internal QC is world-class; external inspectors are not allowed in our facility," immediately cease negotiations. Legitimate export manufacturers routinely accommodate professional inspection agencies.
- Unrealistically Low Pricing: If three factories quote between $8.50 and $9.20, and a fourth offers $4.80, that quote is either a bait-and-switch scheme, counterfeit material, or an outright scam.
- Generic Email Addresses: Communication originating exclusively from free webmail accounts (e.g. `@gmail.com`, `@163.com`, or `@hotmail.com`) without a verified corporate domain.
- Pressure to Close Immediately: High-pressure sales tactics claiming that "raw material prices are doubling tomorrow unless you wire funds today."
- No Prior Export Experience: A factory that has never exported to your destination country will be unfamiliar with customs documentation, phytosanitary requirements, or pallet certification rules.
