China lead times: those who plan backwards are on time
“4–6 weeks production” sounds plannable — until sample approval, inspection, booking lead time and holidays are added. The realistic total calculation from order to dock, the typical time eaters, and the one holiday that shifts entire supply chains every year.

The realistic total calculation
For a sea freight order with a sampling loop, calculate: samples and approval 2–4 weeks, production 4–8 weeks (depending on product and season), quality inspection and corrections 1 week, booking/pre-carriage/loading 1–2 weeks, sea transit to Northern Europe 30–38 days, clearance and on-carriage 3–5 days. Total: around 4–6 months from first contact, 3–4 months for repeat orders without sampling. Rail saves ~2 weeks of transit; air freight turns transport into one week — at five to eight times the freight price.
Chinese New Year: the annual state of exception
Around the Spring Festival (late January/February), China’s factories stand still for 2–4 weeks — the real effect lasts longer: from early January, factories stop accepting new orders, the weeks before are overbooked (quality risk!), and after the festival part of the workforce often does not return, making ramp-up sluggish. Freight rates regularly rise 30–50 % before CNY. Rule of thumb: goods you need in the first quarter must be produced and inspected by mid-December.
The underestimated time eaters
It is not the sea transit that breaks schedules — it is the small loops before it:
- Sampling loops without deadlines: every correction costs 1–2 weeks
- Missing components at the manufacturer (especially electronic chips)
- Rework after final inspection — time well spent, but plan for it
- Full vessels in peak season (Aug–Oct): rollovers without firm bookings
- Golden Week (early October): another week of standstill
How we schedule in projects
We plan backwards from your need date with milestones and buffers in the right places: approval deadlines for samples, production slots confirmed in writing, inspection date before payment release, shipping with firm bookings instead of spot hopes. Every milestone is monitored and delays reported immediately — turning “hopefully on time” into a date with owners.
Common questions about lead times
When must I order for the Christmas season?
Backwards: goods in your warehouse by early October, shipping by mid-August, production start by June at the latest — so order and sample approval in April/May. Those ordering in August compete with peak season for freight space and get December arrivals. For new products with a sampling loop: another month earlier.
Can production be accelerated when it is urgent?
To a limited extent — and with caution: express surcharges buy priority in the production queue, but forced haste measurably costs quality. The more effective lever is transport: rail instead of sea saves two weeks, partial air freight for the first sales batch bridges while the rest sails. This split strategy regularly saves launches.
How binding are lead time promises from Chinese factories?
As binding as their consequences: a promise without contractual penalty and without monitoring is a statement of intent. What works is the combination of a production slot confirmed in writing, interim checks (is progress actually visible?) and balance payment after inspection. That is why in our contracts the deadline stands next to quality — both are monitored, not hoped for.
