The Complete Guide to Air Freight vs Sea Freight from China

Tariff classification (HS code) determines your duty rate. Different suppliers may classify the same product under different HS codes. Always verify the correct HS code and check if your product qualifies for preferential duty rates under trade agreements. An incorrect classification can result in overpayment or customs penalties. Request the supplier's export HS code and compare it with your import country's classification.

Incoterms 2026 clarified several points that often caused confusion. Under FOB, the seller's responsibility ends when goods are loaded on the vessel. Under CIF, the seller arranges and pays for freight and insurance but risk transfers at the port of origin. DDP means the seller bears all costs and risks until delivery. Choose based on your logistics capability, not habit. CIF seems easier but you lose control of shipping decisions.

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.

Total landed cost is the only number that matters when comparing Chinese suppliers.

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.
