SourcifyChina Advisory

1. Supplier Vetting Priority: Demand IATF 16949 with OEM-specific supplemental requirements (e.g., BMW Group Standard GS 93026). Generic ISO 9001 is disqualifying.
2. EV-Specific Risk: Battery component suppliers must comply with UN ECE R100 Rev.3 (2026 enforcement) – audit thermal runaway mitigation protocols.
3. China Sourcing Tip: Verify GB/T 38031-2020 compliance for EV batteries; non-certified suppliers face 100% customs rejection at Chinese ports.

“In 2026, 73% of procurement rejections stem from incomplete IATF documentation – not technical failures. Certify early, audit often.”

Trading Company vs. Genuine Factory: Critical Differentiation Guide

Indicator	Genuine Automobile Factory	Trading Company (Red Flag)
Business License	Scope includes manufacturing (生产) for specific auto parts (e.g., “brake caliper production”)	Scope limited to trading (销售/进出口) with vague terms like “auto parts”
Facility Evidence	• Consistent machine IDs in videos/photos • Dedicated R&D lab with testing equipment • Employee badges with factory name	• Generic “industrial park” footage • No R&D space visible • Staff wear generic uniforms
Pricing Structure	• Itemized COGS breakdown (material, labor, overhead) • MOQ based on production line capacity	• Single-line item pricing • MOQs rounded to “container loads” (not production batches)
Technical Engagement	• Engineers discuss process parameters (e.g., “annealing temp: 580°C±5”) • Provides DFM suggestions	• Focuses on delivery timelines/cost only • Redirects technical questions to “our factory”
Payment Terms	• Accepts LC at sight or 30-day net • Requires deposit only for new molds	• Demands 100% T/T upfront • Insists on payment to offshore accounts

2026 Critical Insight: 41% of “factories” are now hybrid models (trading co. controlling multiple factories). Verify direct ownership via equity records in Qichacha (企查查) – look for ≥51% stake in manufacturing entity.
