Question 1

What is a typical shipping lead time from China to the USA?

Accepted Answer

Door-to-door lead time from China to the USA: By sea: 30–45 days total (2–5 days factory preparation + 5–8 days inland trucking to port + 14–18 days vessel transit + 3–5 days customs clearance + 2–3 days delivery). By air: 10–14 days total (2–3 days factory + 1–2 days to airport + 5–8 days air transit + 2–3 days customs + 1–2 days delivery). By express courier: 5–8 days (1–2 days pickup + 3–5 days transit + 1 day delivery). Peak season (Aug–Nov) adds 5–15 days to all modes.

Question 2

How do I calculate my reorder point based on shipping lead time?

Accepted Answer

Reorder Point = (Average daily sales × Total lead time) + Safety stock. Example: 20 units/day × 35 day lead time + (20 units × 7 days safety stock buffer) = 700 + 140 = 840 units. When inventory drops to 840 units, place the next order. Safety stock = daily sales × number of days buffer you want (7–14 days is typical). This ensures you don't stock out during the lead time window even with minor delays.

Question 3

What adds delay to China shipping lead times?

Accepted Answer

Common delay sources: Chinese New Year (2–4 week factory shutdown, Jan–Feb, book 8 weeks ahead), Golden Week (1-week shutdown, Oct 1–7), Pre-CNY rush (Nov–Dec, sea freight space fills up), Typhoon season (July–October, Hong Kong/Guangzhou port delays), US port congestion (seasonal, West Coast ports), Customs exam (3–7 days if selected, 5–10% of shipments), Vessel schedule changes (1–5 days), Document errors (2–7 days for correction). Plan for a 20% delay buffer on any lead time estimate.

Question 4

What is the difference between production lead time and shipping lead time?

Accepted Answer

Production lead time: Time for the factory to manufacture your goods after order confirmation. Typically 2–6 weeks for standard goods, 8–16 weeks for custom or complex products. This runs in parallel with purchasing raw materials (which can add 2–4 weeks). Shipping lead time: Time for goods to move from factory to your warehouse after production completes. Typically 4–7 weeks by sea. Total lead time = Production + QC inspection (3–5 days) + Shipping. For planning purposes, add both: a 4-week production run + 5-week sea shipping = 9-week total lead time from order to receipt.

Question 5

How does Chinese New Year affect import lead times?

Accepted Answer

Chinese New Year is the most significant annual disruption to China importing. Most factories shut for 2–4 weeks (typically Jan–Feb). Key impacts: (1) Pre-CNY rush: Production bookings in Nov–Dec are very heavy — expect 2–4 week extended lead times. (2) Factories often increase prices 5–15% post-CNY as raw material costs reset. (3) Sea freight space is extremely tight in Jan–Feb as shippers rush goods before and after CNY. (4) Factory staff turnover: 20–40% of workers change jobs at CNY, potentially affecting quality in the first weeks of production. Plan orders to arrive in inventory before Jan 1 or after March.

Question 6

What is the fastest way to ship from China to the USA?

Accepted Answer

Fastest options: DHL/FedEx/UPS Express: 3–5 business days door to door. $15–$25/kg. Air freight (consolidation): 5–10 days. $5–$10/kg. Air LCL: 7–12 days. $4–$8/kg. For emergency restocks, DHL Express is the fastest reliable option. For planned air shipments, a consolidation forwarder is 40–50% cheaper with only 2–5 days slower. The fastest sea freight is a direct-call service (no transshipment) — China → LA direct service takes 12–14 days vs 20–25 days for transshipment routing.

Question 7

How should I calculate safety stock for China imports?

Accepted Answer

Safety stock formula: Safety stock = Z × σ × √(lead time). Where Z = safety factor (1.65 for 95% service level, 2.05 for 98%), σ = standard deviation of daily demand, lead time = average lead time in days. Simpler approach for small importers: Safety stock = Maximum daily sales × Maximum lead time delay. Example: 30 units/day max × 10 extra days delay buffer = 300 units safety stock. For China imports with long lead times, most importers maintain 3–4 weeks of safety stock — more than they would for domestic suppliers.

Question 8

What transit times should I plan for sea freight from China to Europe?

Accepted Answer

Sea freight from China to Europe: Shanghai → Rotterdam: 25–32 days. Shanghai → Hamburg: 27–33 days. Shanghai → Felixstowe (UK): 26–32 days. Shenzhen → Barcelona: 28–34 days. Shanghai → Piraeus (Greece): 20–26 days (Suez Canal route). Note: Post-Suez disruptions (Houthi attacks in Red Sea from late 2023) caused many carriers to reroute around the Cape of Good Hope, adding 10–15 days to Europe routes and raising rates significantly. Verify current routing with your freight forwarder before planning.
