Capacity Booking and Peak Season Planning for Activewear

Capacity is not available on demand, and by the time most buyers realise this the slot is gone. Activewear production peaks twice a year, factories allocate lines to customers who committed earliest, and the customers shouting in month three are the ones who did not book in month one. For a structured product like a medium impact bra, which needs operators trained on the specific operations, capacity is even less fungible than for a simple cut-and-sew tee.

The Activewear Capacity Calendar

Spring and summer programs are typically produced from November to February, and autumn and winter programs from May to August. Add Chinese New Year, which removes effective capacity for two to four weeks and distorts freight availability for several weeks either side. Public holiday periods in the destination market matter too, because they set the in-store date, not the production date.

Map your launch backwards from the retail date and you will find that the production slot you need falls earlier than expected, often into a period you assumed was quiet.

How Much to Book and When

Book 60 to 90 days ahead of required production start for a shared line, and further ahead if you need a dedicated line or a specific trims package. For a first program with a new factory, add another 30 days to absorb sampling slippage.

Reserve 10 to 20 percent above forecast if demand is uncertain. Unused capacity released early is cheap goodwill; capacity you need and cannot get costs the season. Agree a release date by which you will confirm final quantities, and honour it.

Dedicated Versus Shared Lines

A dedicated line gives consistent operators, stable quality and faster throughput, and it usually requires a volume commitment, often a monthly minimum for a defined period. A shared line is flexible and cheaper to access but means your product is one of several running through the same operators, which increases the risk of mixed trims and inconsistent settings.

For a bra with a hook closure and a cut-out, consistency is worth paying for. If your annual program is above roughly 30,000 units of a single block, ask about a dedicated arrangement.

Managing Repeat Programs

Repeats should not be re-booked from scratch. Use a rolling forecast covering three to six months, updated monthly, with the nearest month firm and later months indicative. A blanket purchase order with scheduled releases gives the factory confidence to pre-book fabric greige and trim capacity, which shortens every subsequent order.

Pre-booking greige is one of the most effective and least used tools. It removes the longest item from the critical path for the whole season.

When You Are Late

Three options, in order of cost. First, split the shipment: air freight the launch quantity and send the balance by sea. Second, drop a colourway or a size tail to concentrate volume on the pieces that matter. Third, accept a later delivery and move the launch.

Air freight on a bra is costly relative to unit value because the product is light but bulky when boxed. Flat packing instead of boxing can improve the chargeable weight materially, so decide pack format with freight in mind if air is a realistic contingency.

Terms That Protect You

Put the reserved slot dates, the daily output commitment, the confirmation deadline and the remedy for late delivery in writing. A verbal booking is a placeholder. And keep the relationship in view: the factory that reallocated a line to protect your launch will remember whether you released the unused capacity on time.
