Lead Times & Capacity Planning for Large Apparel Orders

Budget roughly forty to fifty days for bulk production once the pre-production sample is approved, plus about ten days for sampling before that, plus freight. Air freight adds five to eight days depending on destination; sea freight adds four to six weeks and costs a fraction as much. So a realistic first order runs about three months from first conversation to goods in your warehouse, and roughly two months on reorders because the pattern, the trim package and the sample approval already exist. The single biggest cause of delay is not sewing — it is fabric. Knit fabric is produced and dyed in lots, and if your colour needs a fresh dye run that lands before cutting begins. The second biggest is slow sample approval, which is within your control. Any factory quoting three weeks for a first bulk order is either counting only the sewing floor or is not being straight with you.

From a capacity-planning view, delays cluster into three buckets and only one of them is the factory's. Upstream inputs: fabric dyed in lots, trims bought in their own minimums, a shade that fails approval and needs re-dyeing. Decision latency: your own sample sign-off, which is invisible in most plans but routinely adds a week or two. And calendar collisions: Chinese New Year and Eid each shut large parts of the chain for weeks and both move every year, so a plan built on a fixed month rather than the actual dates will slip. Sewing capacity itself is rarely the binding constraint. When you plan, book fabric earlier than feels necessary, put a named person on sample approval with a deadline, and check the holiday calendar before you promise a launch date.

Three months before you need goods on the shelf, as a working minimum, and four if the date is fixed. That breaks down as roughly ten days for sampling, forty to fifty days for production once the sample is approved, and then freight — five to eight days by air or four to six weeks by sea. Add your own approval time, which is the part almost everyone underestimates. If you are launching to a date, work backwards from it and then add two weeks of slack, because the things that slip are rarely under your control: a dye lot that misses shade, a trim supplier running late, a port backing up. Two dates to know before you plan anything — Chinese New Year and Eid each shut down large parts of the supply chain for weeks, and both move every year.
