Sourcing non-standard equipment from China involves factory audits + specification freezing + milestone-based payments (Source: Industry practice): Core principle: Payments should always stay ahead of risks (Source: chinamakershub); Layered approach: Qualifications + contracting entity + payment linked to evidence of progress (Source: Sinospect)—Key rules: No full upfront payments; do not pay based on a fixed timeline (Source: Industry insights).
I.
Supplier Due Diligence
Legal entity: Check registration via SAMR/gsxt.gov.cn + verify business scope alignment (Source: agenceocto); Export record: Export history for HS Codes 84/85 (Source: agenceocto); On-site audit: Inspect equipment, workforce, and workshop; refusal to allow a visit is a red flag (Source: LNV); KPIs: On-time delivery rate ≥97% + response time ≤4 hours + repeat purchase rate 25% (Source: LNV); Samples: 3D prototyping + dimensional and material testing (Source: LNV)—Due diligence: Entity + Audit + KPIs (four-layer verification).
II.
Specification Freezing
Technical attachments: Version-controlled attachments (Source: ChinaValidate); Frozen baseline: Lock in specifications before payment (Source: Sinospect); Change control: Design change approval form (Source: ChinaValidate); Signing authority: Confirm authorization to sign (Source: ChinaValidate); Factory restrictions: Subcontracting prohibited (Source: ChinaValidate)—Specifications: Versioning + freezing + change approval (must precede payment).
III. Milestone Payments
Standard Structure: 30% deposit + 40% upon assembly/testing + 30% pre-shipment (Source: Machine Matcher); High-risk New Suppliers: 20–25% + 25–30% interim + 25% pre-shipment + 25–30% upon arrival (Source: CHINAISPP); Production Start: 20% + raw material receipt + production photos (Source: Goodcan); During Production: 20% + DUPRO report (Source: Goodcan); Upon Arrival: Balance + copy of Bill of Lading (Source: Goodcan)—Payment: Deposit + FAT + Pre-shipment (linked to evidence).
IV.
Third-Party Inspection
FAT: Factory full-load test + buyer’s raw materials + third-party witness (Source: agenceocto); DUPRO: During-production inspection (Source: Goodcan); PSI: Pre-shipment inspection / AQL 2.5 sampling (Source: ChineseCheck); Agencies: SGS/BV/Intertek/TÜV (Source: agenceocto); SAT: Site Acceptance Test (commissioning) (Source: Sinospect)—Inspection: FAT + DUPRO + PSI (retain reports at each stage).
V.
Payment Instruments
Advance Payment Guarantee: Guarantee required for large deposits (Source: Sinospect); Standby LC: Standby Letter of Credit (Source: Sinospect); Letter of Credit: Irrevocable sight LC for amounts over $50,000 (Source: msjcnc); Escrow: Third-party escrow (Source: chinabrccc); Contractual Entity: Beneficiary account name must match the contracting party (Source: China IP)—Instruments: Guarantee + LC + Escrow (selected based on amount).
VI. Contract Control
Right of Acceptance: Inspection for entry/approval (Source: ChinaValidate); Remedy: Remediation period for non-conformance; Breach: Liquidated damages capped at 30% (Source: chinabrccc); IP: Joint registration of drawings and patents (Source: chinabrccc);
Dispute Resolution: Arbitration clause—Contract scope: Acceptance + Breach + IP (clearly specify remedies).
VII. Procurement Recommendations
First, four-tier due diligence (entity verification + factory audit); second, specification freezing; third, milestone-based payments (30/40/30); fourth, third-party inspection (FAT/PSI);
fifth, payment instruments (guarantees/LCs)—Risk control: Due diligence + freezing + milestones (locking in security across three fronts).
