How to Import Chemical Products: MSDS, UN Numbers, and Dangerous Goods

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.

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.

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.
