Lead Time Against Transit Time: The Two Clocks Buyers Confuse
Lead time is how long it takes a supplier to make your order, measured from sample approval to the goods being ready to ship. Transit time is the voyage that follows, from the port of loading to the port of arrival. They are two separate clocks, run by two separate parties, and adding them together rather than confusing them is what keeps a launch date honest.
The confusion is understandable. A buyer asks "how long will it take?" and hears a single number back, often "about 90 days", then plans a shelf date around it. That number almost always describes production alone. The weeks of ocean that follow are a different measurement entirely, and treating them as part of the same figure is the single most common reason a first order lands late. This guide separates the two clocks, shows what controls each, and explains why one is a commitment and the other is only ever an estimate.
The two clocks side by side
The clearest way to hold the distinction is to see what each clock actually covers and who is accountable for it.
| Lead time | Transit time | |
|---|---|---|
| What it measures | Making the goods | Shipping the goods |
| Starts when | You approve the sample | The container is loaded |
| Ends when | The container is loaded at the port | The container is discharged at your port |
| Who runs it | The manufacturer | The shipping line, booked by your forwarder |
| What you control | Approval speed and scope | Choice of forwarder and routing |
| Is it a commitment | Yes, a supplier commits to it | No, it is an estimate that moves |
The last row is the one that matters most and gets least attention. A manufacturer can commit to a lead time because the work happens inside its own facility. Nobody can commit to a transit time, because it belongs to the carrier, the route and the season. A forwarder quoting "28 days" is giving you a planning figure, not a promise, and a buyer who treats it as a promise has no slack when a sailing is blanked or a transhipment is missed.
What the lead-time clock actually contains
Lead time, for a first order, is bulk production: from about 60 days to FOB after sample approval. That covers weaving or knitting the cloth, matching colour to your reference, cutting, making, trimming, finishing, any quilting or embroidery, and packing to your carton plan. Because looms, knitting machines and finishing sit under one team, the stages hand off internally rather than waiting on outside vendors, which is part of what holds the figure to 60 days.
Two points about where this clock starts and stops. It starts at sample approval, not at your first inquiry and not when you place the order. If a sample is still in revision, the bulk clock has not begun, so approval speed is yours to control and directly sets the start date. And it stops at FOB, the moment the container is loaded at Nhava Sheva. Everything after that belongs to the other clock.
Sampling sits ahead of the lead-time clock as a stage of its own: counter samples take about a week on woven goods and about ten days on knitted, from an agreed specification, plus your own review and any revision rounds. Build at least one revision round into the plan even on a well specified product.
What the transit-time clock actually contains
Transit time is the sea voyage, and it is set by the lane, not the supplier. As general guidance only, and never a commitment on a given shipment, ocean transit from western India tends to fall in these broad bands:
| Destination region | Typical ocean transit band (general guidance) |
|---|---|
| Middle East (UAE, Saudi Arabia) | Around 1 to 2 weeks |
| Europe and the UK | Around 3 to 5 weeks |
| US East Coast | Around 4 to 6 weeks |
| US West Coast | Around 3 to 5 weeks |
| Australia and New Zealand | Around 3 to 5 weeks |
These bands move with peak-season congestion, canal routing, transhipment connections and blank sailings, so confirm the current figure with your forwarder for the week you actually ship. The lane-by-lane detail, including the ports and the customs steps at each end, is covered in the shipping guides for each market. For planning, the rule is simple: transit is added to the end of the lead time, never folded inside it.
Why folding the two together goes wrong
When a buyer treats one number as the whole journey, the error is always in the same direction: the goods arrive later than planned, because the clock they dropped is the transit one. A buyer who hears "60 days" and expects stock in the warehouse on day 60 is short by the entire ocean voyage, which on a long lane can be six weeks.
The clocks also fail independently, which is why they should be planned independently. A production delay does not shorten transit, and a fast sailing does not recover a late approval. Each has its own risks: lead time is exposed to revision rounds and scope changes you introduce, while transit is exposed to carrier schedules you cannot influence once the box is booked. Holding them apart lets you see which clock a given delay belongs to, and therefore who can do anything about it.
The terms that govern each clock also differ. Who pays for and controls the sea leg, and where risk passes, is decided by your incoterm, not by the lead time. Under FOB you run the transit clock yourself through your own forwarder; the incoterms guide sets out how that choice changes who holds the second clock.
Planning with both clocks
Buyers who hit their dates count backwards from the delivery date, subtracting both clocks in turn.
- Start with the date stock must be in your warehouse.
- Subtract transit for your lane, with a few days added for customs clearance.
- Subtract the lead time, from about 60 days to FOB.
- Subtract sampling and approval, including at least one revision round.
What remains is the date you need to send a clear specification so the first clock can start. Compress the plan and something gives, usually the sample-review stage, which is exactly the one you least want to rush. Reorders are faster because the sample and specification already exist, so the lead-time clock can start almost immediately; the transit clock, of course, does not shorten on a repeat.

Common questions
Is lead time the same as delivery time?
No. Lead time ends when the goods are loaded at the port. Delivery time, if you mean stock reaching your warehouse, is lead time plus transit plus customs clearance. Ask a supplier which one they are quoting, because "delivery" is used loosely and usually means ready-to-ship, not arrived.
Can a supplier guarantee a transit time?
No, and be wary of one who does. Transit belongs to the shipping line and moves with the route and the season. A manufacturer can commit to a lead time because the work is in its own facility; the sea voyage is an estimate your forwarder updates for the week you ship.
Which clock should I plan the most slack into?
Transit, because it is the one you control least once a sailing is booked. Lead time is fixed work you can plan against, and its main variable, approval speed, is in your hands. Build the buffer against the leg that can slip without anyone on your side being able to act.
Does a faster lead time help if transit is long?
It helps your total timeline, but the two do not trade off against each other. Saving a week in production saves a week overall; it does nothing to the voyage. Plan each clock on its own and add them, rather than hoping one covers for the other.
