“How long will production take?” is the question every importer asks, and the answer from a Chinese supplier is usually “about 30 days” — which almost never means 30 days from today to delivery at your warehouse. Lead time from China is a chain: material, production, inspection, booking, export customs, ocean transit, import clearance, and last-mile delivery. If you plan against the factory’s number instead of the real chain, your launch slips, you stock out, and you beg for air freight at five times the ocean cost. Here is how to build a realistic timeline.
The Real Lead-Time Chain
A typical export order breaks into stages. Treat each one as a separate line item when you negotiate with a supplier.
- Material sourcing: 7–20 days, depending on whether components are off-the-shelf or custom-tooled.
- Mass production: 15–45 days, depending on complexity and the factory’s current queue.
- In-process and final inspection: 2–5 days; a third-party inspection adds 1–3 days for scheduling.
- Export customs declaration and port pickup: 2–4 days.
- Ocean freight: 14–20 days to the US West Coast; 28–35 days to the US East Coast via Panama; 28–35 days to North European ports.
- Destination clearance and last-mile delivery: 5–10 days.
So a “30-day production” order typically reaches your door 55–80 days after deposit — not 30.
Typical Intervals by Product Category
Use these ranges as sanity checks against any supplier estimate:
- Simple consumer goods (apparel, basic plastic items, printed merchandise): production 15–25 days.
- Electronics with PCBA and tooling: 30–50 days; new mold tooling adds another 20–35 days.
- Furniture and heavy goods: 30–60 days.
- Certified or medical-adjacent products: 45–90 days, including validation and documentation.
Always ask the supplier to break its lead time into these stages on a chart. A factory that gives one round number and nothing else is either inexperienced or hiding queue pressure.
The Chinese New Year Factor
The Spring Festival is the single biggest lead-time event of the year. In 2027, Chinese New Year falls on February 6. Although the official holiday is roughly eight days, the practical shutdown spans about four to six weeks: output declines from mid-January as migrant workers leave early, factories stay closed through the first half of February, and full capacity only returns in late February. National Day in early October and the back-to-school peak in August also tighten capacity and raise freight rates.
Planning rule: if you need stock on shelf by mid-March, your ocean container should depart from China before mid-January; otherwise plan to receive after mid-March. Never place a first-time order with a new factory in December — you will hit both the shutdown and an unproven supplier.
Contract Clauses and Follow-Up Rhythm
Verbal lead-time promises are worthless. Write the timeline into the contract as “days from deposit receipt and confirmed artwork/sample,” not “approximately.” Add a liquidated-damages clause for late delivery, commonly 0.5–1% of order value per week of delay, capped at 5–10%.
Then track weekly: production percentage complete, photos from the line, and the QC report. Confirm the official production start date before you release deposit; if the factory is overbooked, negotiate either a later ready date or a written capacity slot. Suppliers that go silent after deposit are the ones that miss it.
Safety Buffer and Planning Rules of Thumb
- Add 20–30% buffer to the factory’s quoted production time.
- For peak season or around Chinese New Year, add an extra 4–6 weeks.
- Place reorders before you run out — use a reorder-point formula, not a calendar.
- For time-sensitive SKUs, split shipments: a small air or rail top-up covers demand while the main ocean lot arrives.
- Build a simple Gantt chart with stage milestones and share it with the supplier. This one step reduces missed deadlines dramatically, because it makes delays visible early.
Sample Lead Time vs Bulk Lead Time
Do not confuse sample lead time with bulk lead time. A factory can often ship a pre-production sample in 5–10 days from existing tooling, but mass production after deposit is a different operation: it requires raw-material batch procurement, line scheduling, fixture setup, and quality validation across hundreds or thousands of units. A sample approved in two weeks does not mean the bulk order will take two weeks; always ask for the bulk lead time separately, in writing.
Also distinguish between first-order and repeat-order lead times. A new product order includes tooling, sampling, and first-article inspection, which can add 20–40 days. A repeat order of an approved product, by contrast, often ships in 15–25 days because materials, molds, and production parameters are already set. Plan your launch timeline around the first order, and build your reorder rhythm around the repeat-order cycle.
Finally, build lead-time assumptions into your cash-flow plan. A supplier that quotes 30 days but actually delivers in 55 days means your deposit is tied up for an extra month; over a year of repeat orders, that working-capital cost is real and should be compared when you evaluate competing factories.
