A 40 ft container usually carries roughly 20 to 24 tonnes of cotton yarn, or around 100 to 120 cotton bales, with the exact figure depending on bale dimensions and density, carton size, cone weight and the weight limit on the road from the mill to the port. Yarn is bulky rather than heavy, so a 40 ft high cube is often filled by volume before it reaches its weight limit, while cotton bales are dense enough that the limit is set by weight and by road regulations in India and at the destination. For planning, assume the lower end of each range until the supplier confirms its own packing figures.
These are working ranges, not fixed numbers. A mill that packs yarn on pallets will fit fewer tonnes than one that floor-loads cartons, and Indian bales pressed at different gin presses vary noticeably in size and weight, so always ask for the specific packing specification before you cost a shipment.
Yarn loading
- Cartons: yarn cones are typically packed in corrugated cartons of a standard weight, floor-loaded in a staggered pattern to use the full height of the container.
- Pallets: palletised cartons are easier to handle at the receiving warehouse but reduce the payload, often by a tenth or more, because of the pallet footprint and the space lost above the top layer.
- Cone weight: larger cones mean fewer cartons for the same tonnage and slightly better density, but your knitting or weaving machines must be able to take them.
- 20 ft containers: usually around half the yarn tonnage of a 40 ft box, used when the order is small or the destination port has restrictions.
Raw cotton bale loading
Indian cotton bales are pressed at the gin to a roughly standard weight and are wrapped and strapped before despatch. Bale density varies with the press, and a well-pressed bale from a modern gin in Saurashtra or Kutch will stack more efficiently than a lighter bale from an older press. The number loaded is governed by the weight limit of the container and the maximum axle weight permitted on the road to Mundra, Kandla, Pipavav or Hazira, so the ginner's packing list and the freight forwarder's weight limit need to be checked together.
Fumigation and phytosanitary requirements for raw cotton, where the destination demands them, are completed before or at the time of stuffing. Bales should be loaded dry and the container checked for leaks, because wet cotton in a sealed box can heat up and degrade during the voyage.
Getting the numbers right
Ask the mill or ginner for a loading plan that states the number of cartons or bales, the gross and net weight, and the stacking pattern, and compare it with the shipping line's permitted payload and the verified gross mass rule at the port. Confirm whether the quote is based on a standard 40 ft or a high cube, since the extra height matters for yarn but not for bales. If your order is close to one container's worth, it is often cheaper to adjust the quantity slightly than to ship a part-filled second box.
How Creston & Co helps
We check the mill's loading plan against the container limits, supervise stuffing so the count on the packing list is the count in the box, and photograph the seal before the container leaves. We send weekly updates while the order is in production and at loading. For help planning the right order size for a full container, book our free 20-minute sourcing review.
