Drive past any cotton farm in northern New South Wales or southern Queensland at the tail end of harvest and you’ll see the same iconic sight: rows of large, wrapped round modules sitting in the paddock, waiting to head to the gin. Each one of those modules represents real money, often several thousand dollars of saleable lint and seed. Yet a surprising number of growers, contractors and newcomers to the industry aren’t sure exactly how much a single round module is actually worth.
This guide breaks it down clearly: how much a round cotton module weighs, how many bales it produces, what a bale of cotton is worth in Australia right now and how to put a realistic dollar figure on each module sitting in your field.
A round cotton module is the large, cylindrical roll of seed cotton produced directly by a modern round-module picker during harvest. Unlike the old square modules that needed a separate module builder and crew, today’s pickers form and wrap each round automatically as they move through the crop.
A standard round module typically weighs between 2,000 and 2,500 kilograms, measures roughly 239 cm in diameter and sits about 244 cm wide. That weight is seed cotton – the raw mix of lint, seed and a small amount of trash and moisture, before any ginning has taken place.
It’s worth being clear on terminology here, because “module” and “bale” are often used interchangeably even though they’re very different stages of the process. If you want the full breakdown, our guide on the difference between a cotton module and a bale covers it in detail. In short: a module is the raw roll that leaves the field, while a bale is the clean, pressed lint that leaves the gin.
This is where the value really starts to take shape. Once a round module reaches the gin, the seed and lint are separated, the trash is removed and the lint is compressed into rectangular bales for sale and export.
In Australia, the industry standard “bale” refers to a ginned lint bale weighing 227 kg (about 500 lb). Industry gross-margin budgets generally assume around 4.25 lint bales per round module, though the exact figure varies with crop quality, moisture, variety and how full the module is packed.
So as a working rule of thumb:
The remaining weight is mostly cottonseed, which, as we’ll see below, is a valuable product in its own right and shouldn’t be ignored when you’re tallying up what a module is worth.
Australian cotton is sold into a global market, so the price of a bale moves daily. Cotton is quoted internationally in US cents per pound, then converted to Australian dollars. The price a grower actually receives is built from three moving parts: ICE cotton futures, the AUD/USD exchange rate and the basis (the local premium or discount for quality, location and timing).
To give you a sense of scale:
Because the figure shifts with the futures market and the dollar, always check a current grower price from your merchant or marketer before making decisions. The numbers above are indicative, not a quote.
Now we can put it together. Take a round module producing four 227 kg lint bales, and apply a mid-range price:
In other words, a single round module commonly carries somewhere between $2,000 and $2,800 of lint value alone, depending on price, yield and how many bales it produces. Multiply that across a paddock holding dozens, or hundreds, of modules and the figure quickly goes up.
It’s also worth remembering that the headline price isn’t the whole story. Quality drives the basis component of the price – clean, well-coloured, low-trash lint with good staple length and strength earns a premium. On the other hand, weather-stained, contaminated, or moisture-affected fibre is discounted. That means two modules with identical bale counts can fetch noticeably different returns based purely on the condition the lint arrives in. Looking after your modules through storage and transport isn’t housekeeping; it’s part of the pricing equation.
And that’s before the seed.
Cotton lint contributes the lion’s share of crop income, roughly 85%, but cottonseed makes up the remaining 15% or so, and it’s far from a throwaway by-product. Cottonseed is a high-value livestock feed (high in protein, energy and fibre) and a source of cooking oil. Around 200 kg of oil can be extracted from each tonne of seed.
For growers storing seed cotton or cottonseed on-farm, keeping it dry and contamination-free is essential to protecting that extra slice of income. Quality ground sheets help prevent ground moisture and dirt from downgrading stored seed before it’s used or sold.
Here’s the part that matters most once you understand the dollars involved: a round module is only worth its full value if the lint inside stays clean, dry and uniform from the field to the gin. Rain, UV exposure, dirt and rough handling can all downgrade fibre quality, and a downgrade means a lower price per bale, straight off your bottom line.
That’s exactly why the wrap doing the work matters so much. A premium round module cotton wrap keeps the module uniform and protected through picking, storage and transport, with features like embedded RFID tags for tracking each module to the gin. The quality of film has a direct, measurable effect on returns, something we explore in depth in our look at why advanced cotton wrap matters for grower ROI.
If you’re weighing up your options for the season, our rundown of what to look for when choosing a wrap is a good starting point. And for those rare but costly moments when a module is damaged in the field, emergency recovery tarps can hold a compromised module together and stop a small problem.

A standard round cotton module weighs around 2,000 to 2,500 kg of seed cotton and measures roughly 239 cm in diameter by 244 cm wide. This is the raw weight before ginning separates the lint from the seed.
Most round modules yield around four to 4.25 ginned lint bales, with each Australian bale weighing 227 kg. The exact number depends on crop quality, moisture and how densely the module is packed.
The Australian industry standard is a ginned lint bale of 227 kg (about 500 lb). This is the “per bale” figure used across grower budgets, levies and marketing.
Australian cotton has historically traded between roughly AUD $300 and $600+ per bale, with a recent average near $529 and values firming toward $640+ through 2026. Prices move daily with global futures and the exchange rate, so confirm a live price with your merchant.
Yes. Fibre that arrives at the gin clean, dry and uniform attracts a better price, while moisture damage, contamination or colour fading can pull your grade and your price per bale down. Protecting the module is one of the lowest-cost ways to defend the value already grown.
Every round module in your paddock is worth thousands, make sure that value reaches the gin intact. With over 30 years supplying the Australian cotton industry, Polytex builds wraps and tarps engineered for our conditions, backed by fast nationwide delivery.
