The Complete Guide to Sample Development with Chinese Manufacturers

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.

The sourcing cycle from initial contact to first shipment typically takes 3-6 months for new products. Month 1: supplier research and initial contact. Month 2: sample development and evaluation. Month 3: negotiation and order placement. Month 4: production (varies by product). Month 5: inspection and shipping. Month 6: delivery and evaluation. Plan your inventory accordingly and don't expect to compress this timeline without cutting corners.

Payment terms follow a standard progression in China. Transaction 1: 30% deposit, 70% before shipment. Transaction 2-3: 30% deposit, 70% against B/L copy. After 1 year: possible 30% deposit, 70% 30 days after B/L date. L/C at sight is standard for large transactions. Never jump ahead in this progression — let the track record justify each step. Trust is earned through consistent performance.
