How long does clothing manufacturing take? A realistic timeline

Clothing manufacturing takes as long as its slowest approval, and there is no honest single figure: every lead time is quoted per order, because it depends on the fabric, the number of sample rounds and the factory’s bookings. What you can do is list the stages, get a date for each from your supplier, and plan backwards from your launch. The one stage with public figures is transit: SEKO Logistics publishes 22 to 30 days by sea from Chattogram to the UK and Europe, 18 to 35 days to the United States, and 2 to 5 days by air.

Why nobody can give you one number

Any supplier who quotes a fixed lead time before seeing your product is guessing. Five things decide the real figure:

• Fabric. A stock fabric in a stock colour is available quickly; a custom colour or a special yarn has to be knitted or woven and dyed first.
• Sampling rounds. A repeat style may need one approval; a new fit can need three rounds before it is right.
• Decoration and trims. Custom labels, zips, prints and washes each have their own approval and supply time.
• Factory bookings. A line that is full in peak months starts your order later than one with open capacity.
• Your own speed. Every approval waits on a decision from the brand.

Lead time pressure is common across global supply chains. In a 2016 ILO survey of 1,454 suppliers in 87 countries, only 17 per cent considered their orders to have enough lead time, and the majority said that more than 30 to 50 per cent of their orders had insufficient lead times. The ILO notes that suppliers often respond with overtime, casual labour or outsourcing, which are exactly the conditions a careful buyer wants to avoid.

What a quoted lead time actually covers

Before comparing lead times from two suppliers, check what each one measures. A lead time quoted “ex-factory” or to FOB usually runs from a trigger, such as order confirmation or pre-production approval, to the day goods leave the factory or are loaded at the port. It does not include sampling before the trigger, transit, customs clearance or delivery to your warehouse. A delivered quote covers far more of the journey. Two quotes that look weeks apart can describe the same speed measured from different starting points. Ask each supplier three questions: when does the clock start, when does it stop, and which approvals must you give before it starts.

The stages, in order

Our guide to starting a clothing brand with a Bangladesh factory gives a short overview. Here is the full sequence a production plan has to cover, with what each stage waits on.

Our how we work page shows the same stages from our side, including who signs off at each one.

Build the plan backwards from your launch date

Start from the date the goods must be sellable and work back. A plan built forwards from “we start now” always looks faster than reality, because it assumes every approval happens on the first day it could.

1. Launch date. The fixed point.
2. Stock ready to sell. Subtract the time you need to receive, check, photograph and list the goods.
3. Arrival at your warehouse. Subtract customs clearance and delivery from the port or airport.
4. Departure from Bangladesh. Subtract transit. By sea, SEKO’s published ranges are 22 to 30 days to the UK and Europe and 18 to 35 days to the United States, depending on routing and transshipment; by air, 2 to 5 days. Use the top of the range when planning.
5. Final inspection and loading. Subtract the dates your supplier quotes for inspection, packing and export documents.
6. Bulk production. Subtract the production time quoted for your order.
7. Pre-production approval. This is the gate. If it is late, every later date moves.
8. Fabric booking and sampling. Subtract the fabric time and the sample rounds you expect, plus your own review time for each round.

Here is the same plan as a worksheet for a UK launch by sea. Only the transit line has a public figure; every other line is filled in from your supplier’s quote and your own schedule.

The date that falls out at the bottom is when you must send a complete brief. If that date is already past, change the launch, the fabric, the number of styles or the freight mode, not the approval steps.

The time and action calendar

A time and action calendar, often called a T&A, is the working version of that plan. It is a table with one row per milestone and columns for the planned date, the actual date, who is responsible and a comment. Typical rows are sample dispatch and approval, lab dip approval, fabric in-house, trims in-house, pre-production approval, cutting start, sewing complete, final inspection and shipment.

Three habits make it useful rather than decorative:

• Owners on the brand side. Every approval row has a named person at the brand, with a date.
• Weekly updates. The actual dates are filled in as they happen, so a slip is visible the week it occurs.
• A rule for slips. Agree in advance what happens if an approval is late: the ship date moves, or the freight mode changes, and who pays for any difference.

What delays most orders

Sewing is rarely the problem. The common causes of delay sit before production starts:

• Incomplete specifications. In the same ILO survey, 72 per cent of suppliers said inaccurate technical specifications from buyers led to additional time and costs spent on sampling.
• Slow approvals. Fit comments, lab dips and strike-offs that wait days for a reply.
• Custom fabric and colours. A colour that fails its lab dip goes back to the dye house.
• Late changes. A change after pre-production approval can mean new fabric, new trims or a new sample.
• Trims. A missing label or zip stops a finished order from being packed.
• A failed inspection. Rework and re-inspection take time, which is why inline checks during production matter.

Our sampling and fabric and trim sourcing pages explain how those two stages are run.

Peak season, Eid and public holidays

The two Eid holidays are the biggest calendar factor in Bangladesh, and their dates move earlier each year because they follow the Islamic lunar calendar. In 2026, the government’s holiday list, announced in late 2025, gave five days for Eid-ul-Fitr and six for Eid-ul-Azha. Both were later extended: the government declared seven days from 17 to 23 March for Eid-ul-Fitr and seven days from 25 to 31 May for Eid-ul-Azha, according to The Daily Star.

Those are government holidays. Factories set their own closures, and production also slows before and after as workers travel home. The practical rules:

• ask your supplier for its holiday calendar when you place the order;
• avoid planning a pre-production approval or a ship date in the weeks around Eid;
• check the official dates each year, because they depend on the moon and can change at short notice.

Sea, air or a split shipment

Freight mode is the one stage you can buy time on. SEKO notes that air freight costs roughly 5 to 8 times more per kilogram than ocean freight, so air is best used selectively: a launch quantity, a few sizes that sell first, or an order that slipped. A common approach is a split shipment: a small first portion by air to meet the launch, and the rest by sea. Our logistics and shipping page covers freight modes, incoterms and documents.

How to shorten the timeline honestly

• Use a stock fabric in a stock colour for a first order.
• Send a complete brief with measurements, a reference garment and quantities per size and colour.
• Answer every approval within a day or two, and give fit comments in centimetres.
• Book fabric early once colours are approved, even if the size split is not final.
• Reorder proven styles: a repeat with an approved pattern skips most of the sampling stages.
• Freeze the design at pre-production approval. Changes after that point cost the most time.

What to do next

Send us your launch date, styles and rough quantities through the quote request on our contact page. We reply within one working day and quote the lead time for your specific order, stage by stage, so you can see whether your date works before you commit.
