The Ultimate Guide to Sourcing Electronics from Shenzhen in 2026

Total landed cost is the only number that matters when comparing Chinese suppliers. It includes: factory price, inland freight to port, export customs fees, ocean/air freight, insurance, import duties, VAT, customs brokerage, and inland freight from destination port. A $10 product FOB can easily become $14-16 landed. Most first-time importers forget at least three cost components and end up with negative margins.

Sample development has three stages with different costs. Stage 1 — existing sample or stock item: free or low cost, typically 1-3 days. Stage 2 — modified sample based on existing design: medium cost, 5-10 days. Stage 3 — fully custom sample: highest cost, 15-30 days. Many buyers skip to Stage 3 when Stage 1 or 2 would suffice. Save your custom development budget for when it truly matters.

Quality control should not be a single inspection at the end. Build a multi-point QC plan: (1) raw material inspection before production starts, (2) first article inspection when the first unit comes off the line, (3) in-process inspection at 30% and 60% completion, (4) pre-shipment inspection when 80% is packed, (5) container loading supervision. Each step costs a fraction of catching defects at the destination.
