Last week in Shenzhen a small-appliance seller asked me one thing: "If I book on Oct 8, do I make White Friday?"
So we ran the numbers. Full container, Shenzhen to Jeddah, late September 2026 quoting USD 2,800-3,600 per 40HQ. Sailing 22-28 days. Add customs, devanning and inbound — call it 35-40 days door to shelf. Ship Oct 8, stock lands around Nov 15. White Friday is Nov 27. Tight, zero buffer.
Air, then. Shenzhen to Riyadh, general cargo: RMB 30-38/kg. Three to five days to the airport, two to three for clearance. Expensive but fast. A 2kg unit costs RMB 45-55 more by air than by sea. On a SAR 199 retail price, that's roughly 6 points of margin gone.
My take: never push one channel for the whole PO. Split SKUs into three tiers. Tier A — your top 20% sellers over the last 90 days — flies, and you hold 25-30 days of cover. Tier C long tail goes in the container with 60 days cover. The middle rides sea-expedited or sea-air, in the warehouse within a week of Jeddah arrival.
Honestly, "all sea" is where people get burned. One stockout on White Friday and the ranking does not recover before Christmas.
Two more things. Slot bookings: Amazon AE/SA and Noon FBN fill up by mid-October, so reserve three weeks out. And your invoice and certificate of origin must match the packing list line for line. One mismatch, three to five days gone. Get the HS code wrong and you are into an amendment loop nobody will rush in peak.
For what it's worth, 8ship saw air quote requests from China to the Gulf climb more than 40% in the last week of September versus August. Space goes first come, first served.
So how are you splitting yours — all air, or betting the sea lanes stay clear?
