Almost every importer has had the same experience: the factory quoted 25 days, the goods left in 45, and nobody could say exactly when it went wrong. Usually nothing went wrong — the quoted number simply measured something different from what the buyer assumed. This article is for companies importing in commercial volumes, from a container or a few thousand units, who need to plan a sales season backwards from a real date rather than an optimistic one.
What a lead time is actually made of
- Order confirmation and payment clearing. An international transfer takes days, and most factories do not schedule anything until the deposit lands.
- Raw material procurement. Often the longest hidden block: 5–20 days, and the factory usually does not order material before payment.
- Queue. Your order joins a schedule that already has orders in it. This is the part nobody quotes.
- Production itself. Usually the shortest part.
- QC, rework and packing. Add days, especially if the first inspection finds anything.
- Booking and delivery to port. Space is not always available on the date you want.
When a factory says "25 days," it very often means production only, in working days, starting from the day the material arrives — which can be three weeks after you thought the clock started.
Realistic ranges
- Standard catalogue goods, in stock or semi-finished: 10–20 days
- Standard goods, made to order, no customisation: 20–35 days
- Custom or branded product, existing tooling: 30–45 days
- First order with new tooling: add 30–60 days for the tooling and sample rounds — see tooling and moulds: cost and ownership
- Industrial equipment and machinery: 45–90 days, sometimes more
- Sea freight on top: 30–50 days on the main routes; see container shipping from China
A first-time custom product realistically runs four to seven months from signed specification to warehouse. Repeat orders are dramatically shorter because tooling, samples and the golden sample already exist — the full sequence is in how manufacturing in China actually works.
The seasons that move your date
- Chinese New Year. The single biggest factor. Factories close for one to three weeks around the holiday — which falls in late January or February depending on the year — but the real disruption is longer: production winds down for weeks beforehand as workers travel home, and afterwards a share of the workforce does not come back at all, so lines restart at reduced capacity with new staff. Quality dips on both sides of the holiday. Anything that must arrive in the first quarter should be in production by November and shipped by the end of December.
- Golden Week (first week of October) and the early-May holiday. Shorter, but they also congest ports and trucking.
- Peak shipping season, roughly August to October. Factories are busy, freight rates rise and space tightens ahead of the Western holiday season.
- Power and energy restrictions. In some provinces and some years, industrial power is curtailed, and production runs on a reduced schedule.
- Material market shocks. When a raw material spikes or runs short, delivery dates move regardless of what the contract says.
Why 25 days becomes 45
- The clock starts later than you think. Deposit clearing, material ordering and sample approval all precede day one.
- "Days" means working days. Twenty-five working days is five calendar weeks.
- Sample revisions are not counted. Each round of changes adds a week and is treated as your delay, not theirs.
- The queue is invisible. A larger customer's order can move ahead of yours.
- Rework after inspection. Defects found at inspection push the shipping date, which is one more reason for quality control during production rather than only at the end.
- The booking. Production finishing does not mean the container sails that week.
How to fix a deadline that means something
- Define the start trigger explicitly: "X days from receipt of deposit and written approval of the PP sample."
- State calendar days, not working days, or state working days and name the holidays excluded.
- Require a production schedule with milestone dates: material in, production start, mid-production, QC, packing, ex-works.
- Require weekly photo or video reports against that schedule — the first slipped week is visible long before the last one.
- Include a delay penalty with a defined cap, and tie part of the balance to on-time shipment. The payment mechanics are in how to pay a Chinese factory safely, and the clauses belong in the contract with the factory.
- Book freight early in peak season. A finished order waiting for space is still a late order.
Planning backwards from your sales date
- Target on-shelf date
- minus customs clearance and inland delivery: 5–10 days
- minus sea transit: 30–50 days
- minus port cut-off and booking: 7–10 days
- minus production: 20–45 days
- minus samples and approvals: 10–30 days
- minus tooling, if new: 30–60 days
- minus Chinese New Year, if the window crosses it: 2–4 weeks
Run that arithmetic once and the answer is usually the same: the order needed to start earlier than it feels like it did.
A lead time is not a promise about the future. It is a description of a queue you cannot see, measured in units you did not agree on, starting from a day nobody wrote down. Fix those three things and the date becomes real.
Holding the schedule for you
We define the start trigger and the milestone schedule in the contract, chase the material procurement stage that nobody else watches, run in-production inspections so rework does not appear at the end, and book freight against the real ex-works date. Seven years, 3,500+ deliveries and 340+ verified suppliers — real projects in our case studies.
