Frequently Asked Questions

MOQ varies by product and manufacturer. For our focus categories (fans, humidifiers, lighting), typical MOQs range from 300-1,000 units for existing models and 1,000-3,000 units for custom OEM/ODM orders. We negotiate MOQ flexibility on your behalf, especially for first orders and market testing.

A typical sourcing project takes 4-8 weeks from initial inquiry to shipping. This includes: supplier matching (3-5 days), sampling (2-3 weeks), production (2-4 weeks depending on quantity), and shipping (1-4 weeks depending on method). Rush orders and smaller quantities can be faster.

We implement a multi-checkpoint QC process: Golden Sample approval before production starts, in-line inspections at 20% and 50% production, and a final pre-shipment AQL 2.5 inspection at 100% completion. We provide detailed photo and video QC reports for every inspection.

Standard payment terms are 30% deposit before production and 70% balance before shipping (T/T). For larger orders, we can negotiate letter of credit (L/C) terms. We help structure payment milestones to protect your capital throughout the process.

Shenzhen offers unmatched prototyping capabilities for AI hardware. We coordinate the EVT (Engineering Validation Test), DVT (Design Validation Test), and PVT (Production Validation Test) stages with local engineering firms and factories. Typical timeline: 4-12 weeks from concept to working prototype depending on complexity. Read our prototyping guide.

AI hardware products typically require FCC (US), CE RED (EU), UN38.3 (lithium batteries), and RoHS/REACH (EU). Products for children also need CPSIA, ASTM F963, and COPPA compliance. We coordinate all certification testing with accredited labs in Shenzhen. Read our certification guide.
