Weeks of sea freight on most lanes

Almost every brand asks the same question too late: “I want this live by [Your Launch Date]. When do I have to start?”

The honest answer trips people up, because the calendar runs in reverse.

Your on-sale date is fixed. Everything that has to happen before it: design, samples, fabric, sewing, inspection, and shipping stacks backward from there.

Miss the start date and no amount of rushing the factory buys the weeks back.

This guide lays the whole thing out the way we actually schedule it: the realistic 12–20 week breakdown, which steps must happen in order and which run side by side, and the busy seasons that quietly eat your slot.

And the buffer you need so a second sample round or a slow port doesn’t blow up your launch.

At the end, there’s a week-by-week countdown calendar you can print and pin up.

The realistic timeline

What actually happens across 12–20 weeks

Why the range?

A small order on a fabric we already stock, with one clean sample round and air freight, can land in near 12 weeks.

A larger run in a custom-dyed fabric, with two or three sample rounds and ocean freight, runs closer to 20.

Here’s the full sequence, with rough durations and whether each block sits on the critical path (it can’t start until the one before finishes) or can run in parallel.

1–2

Weeks

Design lock & tech pack

Final artwork, measurements, fabric and trim choices, and a clear tech pack a factory can quote and sew from. This is your side of the table; the faster and tighter it is, the faster everything downstream moves.

CRITICAL PATH

How to build a tech pack →

1

Week

Quote, fabric sourcing & slot booking

The factory quotes the job, you confirm, and a production slot is reserved. Fabric and trims are sourced and priced now, and if your fabric needs knitting or dyeing to spec, the clock on that starts here, in parallel with sampling.

MOQ & pricing explained →

3-6

WeekS

Sampling rounds (proto → fit → PP)

The step brands underestimate most. A proto sample proves the concept, a fit sample dials in the measurements, and a pre-production (PP) sample is the signed-off gold standard bulk is matched against. Each round is roughly 7–10 days to make, plus courier time each way. Plan for two to three rounds, not one.

CRITICAL PATH

How sampling works →

3-5

WeekS

Fabric & trim production

Custom knitting, dyeing, and finishing of your fabric, plus woven labels, drawcords, zippers, and packaging. This is a hidden long pole: it’s long, but it can run alongside sampling once the fabric spec is locked, so it rarely needs to add weeks if you book it early.

Can run in parallel

4-8

WeekS

Bulk production (cut–make–trim)

Cutting, sewing, and finishing the full order. Duration scales with quantity and how busy the floor is. Bulk can’t start until the PP sample is approved and fabric is in-house, which is exactly why those two steps decide your whole schedule.

CRITICAL PATH

2-4

WeekS

QC inspection & packing

A final quality inspection to an agreed AQL standard, then folding, polybagging, and carton packing. Short, but never skip it. A problem caught here is cheaper than a return wave after launch.

CRITICAL PATH

1-6

WeekS

Freight & customs clearance

Air freight is roughly a week, door to door, and costs more. Sea freight is usually 4–6 weeks on most lanes plus a few days to clear customs and costs far less. Your freight choice is often the single biggest lever on the whole timeline.

CRITICAL PATH

1-2

WeekS

Receive, list & go live

Inbound check at your warehouse, product photography (shoot it earlier with your PP sample), listings, and the pre-launch marketing push. Then you’re on sale on the date you planned for because you started on time.

Can run in parallel

Add the critical-path blocks, not all of them. Because fabric production, photography, and store setup overlap other steps, the timeline isn’t the sum of every box. It’s the length of the longest continuous chain, the critical path. That’s what the next section maps.

What stacks vs what overlaps

Two tracks running at once

The mistake that wastes the most time isn’t a slow factory; it’s running everything in single file when half of it could overlap. There are two tracks. The critical path sets your earliest possible on-sale date; nothing finishes sooner than this chain allows. The parallel track is everything you can get done while the critical path runs, so it never adds a single day if you start it on time.

Critical path sets your floor

Each link can’t start until the one above is done. This chain is your timeline.

  • Design lock & tech pack
  • Proto → fit → PP sample approval
  • Bulk cut–make–trim
  • QC inspection & packing
  • Freight & customs clearance

Parallel track costs no extra time

Run all of this during the critical path. Start it late, and it becomes your bottleneck.

  • Custom fabric knitting & dyeing (once spec is locked)
  • Trims, labels, drawcords & packaging procurement
  • Product photography & lookbook (shoot the PP sample)
  • Store, listings, size guide & copy
  • Email list, content & launch marketing

The one overlap that saves the most: lock your fabric spec at PP-sample stage and book the knit/dye run immediately. Fabric lead time then disappears inside your sampling and bulk windows instead of being bolted onto the end. Brands that don’t do this often add three to five weeks for no reason.

When the calendar fights back

The peak-season capacity crunch

The 12–20 week range assumes a normal stretch of the year. A few predictable windows compress capacity across the whole supply chain: factory floors, yarn mills, accessory suppliers, and ocean freight all at once. Plan on one of these unaware, and your “16-week” job quietly becomes 22.

Q4

Western holiday rush

Everyone wants stock in hand for Black Friday and Christmas, so summer bookings pile up. To launch in Q4, lock your production slot by spring; late slots get squeezed or bumped.

CNY

Lunar New Year ripple

Chinese New Year (late January to mid-February; the exact date shifts each year) shuts much of Asia for two to four weeks. Even a Pakistan-based floor feels it through yarn, trims, and freight space drying up around it.

EID

Eid factory closures

Eid al-Fitr and Eid al- Adha closes South Asian factories for around a week, and the dates move about eleven days earlier every year. Build the closure into any run that straddles them.

Freight has its own peak. Ocean space tightens, and rates climb from roughly August into October as retailers ship for the holidays. If your run lands in that window, book freight early and price in higher rates or weigh air for the part of the order you need first.

The rule of thumb: in normal periods, reserve your bulk slot 8–12 weeks ahead. Within roughly eight weeks of any peak above, add weeks to your plan and book earlier than feels necessary. Capacity is first-come; the brands that lock slots early simply get made first.

Where to spend your slack

Buffer and the three long poles

A timeline with zero buffer isn’t a plan; it’s a hope. But you don’t pad every step evenly; you protect the three things most likely to slip. We call them the three long poles: the items that, when they run long, drag the whole launch with them.

01

Long pole

Sampling rounds

The most common cause of a blown timeline. Brands budget one round; reality is often two or three as fit, and details get dialed in. Buffer: plan for three rounds from the start. If you only need two, you’ve gained a week, not lost one.

02

Long pole

Fabric lead time

Custom knit and dye runs are long, and a color that comes back off-standard means re-dyeing. Buffer: lock fabric and book it early so it runs in parallel, and approve lab dips before bulk dyeing rather than after.

03

Long pole

Freight & customs

Sea schedules roll, ports congest, and customs can hold a shipment for inspection. Buffer: add one to two weeks on ocean freight, and never schedule stock to land the same week you go on sale.

The golden buffer rule: aim for your stock to land two weeks before your on-sale date, not on it. That fortnight absorbs a slow sample round, a delayed vessel, or a customs hold, and if nothing goes wrong, it becomes calm time to photograph, list, and build pre-launch hype instead of firefighting.

The signature tool

The Drop-Back Calendar

Set Drop Day as your on-sale date, then count backward. This is the full 20-week version with sea freight and a buffer baked in the safe default. On a stocked fabric with air freight, you can compress it toward 12.0.

Countdown Milestone What you’re doing
Drop −20 Lock the design Finalize artwork, fit intent, and fabric & trim choices. Build the tech pack.
Drop −19 Quote & book the slot Send the tech pack, confirm the quote, and reserve your production slot. Start sourcing fabric.
Drop −18 Proto sample First sample made and shipped. Review the concept, not the fine fit yet.
Drop −16 Fit sample Measurements dialled in. Lock the fabric spec now and book the knit/dye run in parallel.
Drop −14 PP sample & sign-off Approve the pre-production gold standard. Photograph this sample for your launch shoot.
Drop -13 Bulk begins Fabric in-house, cutting starts. Kick off store build, listings & email list in parallel.
Drop −12 → −7 Cut–make–trim Full order sewn and finished. Meanwhile, lookbook, content, and pre-launch marketing.
Drop −6 QC & pack Final AQL inspection, then fold, bag, and carton. Book freight if not already booked.
Drop −6 → −2 Freight & customs On the water and through customs. (Air freight collapses this to about a week.)
Drop −2 Stocklands buffer Goal date for stock at your warehouse. Inbound check, list the rest, final hype.
Drop −1 Pre-launch Teasers out, early-access list primed, everything staged and ready.
Drop 0 You’re live. 🚀 On sale — on the date you planned for, because you started on time.

To compress toward 12 weeks: start with a fabric we already stock (removes the knit/dye pole), hold sampling to one or two clean rounds, and use air freight (turns ~5 weeks into ~1 week). The critical path shortens; the order of operations stays the same.

Before you start the clock

The pre-start checklist

Drop −20 only works if you’re actually ready to begin. Tick these off before you count back, so day one is a real start, not a false one.

✓  Ready-to-start checklist

  • Fixed on-sale date. The whole calendar hangs off this. Pick it first.
  • Final artwork & design locked, not “nearly there.” Changes after sampling reset the clock.
  • A complete tech pack: measurements, fabric, trims, construction, labels everything a factory needs to quote and sew.
  • Target quantity & size run drives MOQ, price, and how long bulk takes.
  • Reference samples: A hoodie whose fit or feel you want matched speeds up sampling enormously.
  • Freight decision: Air or sea? It’s the biggest single swing in your timeline; decide early.
  • Peak-season check: Does your run cross Q4, Lunar New Year, or Eid? If so, add buffer and book earlier.
  • A booked production slot: Capacity is first-come. A confirmed slot is what makes the rest of the calendar real.

First-drop timeline FAQ

About 12 weeks if everything lines up: a fabric already in stock (no custom knit or dye), one or two clean sample rounds with fast approvals, a modest quantity, and air freight. The order of steps never changes you’re just shortening the long poles. Anyone promising a fully custom cut-and-sew run in two or three weeks is either using blanks or cutting a corner you’ll feel later.

Because it’s rarely one. A prototype proves the concept, a fit sample corrects measurements, and a PP sample is the approved standard bulk is matched to. Each round is roughly 7–10 days of making plus courier time both ways, and most first drops need two or three rounds before the fit is right. It feels slow, but it’s the cheapest place to catch problems far cheaper than discovering them across hundreds of finished units.

We don’t recommend it. The PP sample is your insurance: it’s the physical reference the whole bulk order is judged against. Skipping it means the first time you see your product made correctly is when the full order arrives and if the fit or finish is off, there’s no buffer left to fix it before launch.

A lot. Sea freight is usually 4–6 weeks on most lanes, plus customs; air freight is roughly a week door to door. That’s the single biggest lever you control. A common play is to airfreight a small first batch to launch on time, then bring the bulk by sea to keep costs down.

Count back 20 weeks from your on-sale date and treat that as your start, then start earlier, because Q4 is peak season. Factory floors fill with holiday orders over the summer, and ocean freight tightens from roughly August into October. Lock your production slot by spring to avoid being squeezed.

In order: extra sample rounds from designs that weren’t fully locked, fabric that wasn’t booked early enough to run in parallel, and freight or customs delays. All three are predictable, which means all three are bufferable. Plan for three sample rounds, book fabric the moment the spec is locked, and aim for stock to land two weeks before launch.

A tech pack makes the quote faster and far more accurate, and it prevents the misreads that cause extra sample rounds. If you don’t have one yet, we can help build it from your artwork and a reference garment but the more complete it is on day one, the faster the whole calendar moves.
