The Cotton Supply Chain Explained: From Farm to Futures Market

Cotton supply chain defined The cotton supply chain begins at the gin — the machine that separates cotton fibre from its seed — and ends with yarn, fabric, and garments. Raw cotton is grown primarily in India, China, the US, Pakistan, and Brazil. It is graded by staple length, strength, colour, and fineness. The ICE Cotton No. 2 futures contract (ticker: CT), quoted in cents per pound, is the global price benchmark. Cotton competes directly with polyester for share of global textile demand.

Cotton Types: Upland vs Long-Staple

Not all cotton is the same. The global cotton market runs on two main fibre types, and they trade at very different prices.

Upland cotton (Gossypium hirsutum) accounts for over 90% of global cotton production. It is the standard commercial grade — medium staple length (roughly 1 to 1.3 inches), adequate strength, and grown across a wide range of climates. US Texas production, Indian cotton, and most West African cotton are upland varieties. It is used in the vast majority of everyday textiles: denim, T-shirts, basic woven fabrics.

Extra-long staple (ELS) cotton — which includes Pima cotton (grown in the US southwest, Peru, and Australia) and Egyptian Giza cotton — has staple lengths above 1.4 inches. The longer fibres spin into finer, stronger, smoother yarn. ELS cotton is used in premium products: luxury dress shirts, high-thread-count bedding, fine knitwear. It trades at a significant premium to standard upland cotton — sometimes 50-100% above the ICE No. 2 benchmark.

This distinction matters for sourcing professionals. A buyer specifying “cotton” without a staple length will typically receive upland. A buyer requiring fine yarn for premium garments needs to specify ELS and source accordingly.

Where Cotton Is Grown: Key Producing Regions

Country	Share of World Production	Export Role	Key Regions
India	~25%	Net exporter in most years	Maharashtra, Gujarat, Andhra Pradesh
China	~24%	Net importer (largest consumer)	Xinjiang (~85% of Chinese crop)
USA	~14%	Major exporter	Texas, Mississippi Delta, California
Brazil	~12%	Fast-growing major exporter	Mato Grosso (Cerrado)
Pakistan	~6%	Net importer (large textile sector)	Punjab, Sindh
Australia	~4%	Export-oriented	New South Wales, Queensland

India is the world’s largest cotton producer but its textile industry is also enormous, so a significant portion is consumed domestically. India’s export position varies year to year depending on domestic crop size and government export policy.

China produces a large crop but consumes far more than it produces, making it the world’s largest cotton importer in most years. Its production is heavily concentrated in Xinjiang, the autonomous region in northwest China (see section below).

The USA is a consistent major exporter. Texas is the single most important US cotton state — an area so large and climatically variable that Texas weather alone can shift global cotton prices. Drought in west Texas in 2022 destroyed a large portion of the US crop and drove cotton futures to near-historic highs.

Brazil has emerged as the most important cotton export competitor to the US over the past decade. The Cerrado region of Mato Grosso produces high-quality cotton at competitive costs, and Brazil’s cotton export volumes have roughly tripled since 2010.

Ginning: The First Processing Step

When cotton is harvested, each boll contains both the white fibre (called lint) and the seed. The two must be separated before the cotton can be processed into yarn. This is the job of the cotton gin.

The gin was invented by Eli Whitney in 1793, but modern industrial gins work on the same basic principle: revolving saw-tooth blades pull the lint through a wire mesh while the seeds, too large to pass through, are left behind. The seed is a valuable by-product — it is pressed for cottonseed oil used in cooking and processed into cottonseed meal for animal feed.

After ginning, the lint is pressed into bales — the standard commercial unit of cotton trade. A standard US cotton bale weighs approximately 480 pounds (roughly 218 kg) and is wrapped in burlap or synthetic fabric for handling. Cotton bales are stacked in gin warehouses before sampling and classing.

In the US system, cotton is sampled at the gin warehouse. The sample goes to a USDA classing office, where trained classers and automated instruments measure quality.

USDA Grading: How Cotton Quality Is Measured

USDA cotton classing assigns every bale a grade based on four key measurements:

Staple length — measured in thirty-seconds of an inch. A fibre described as “38” is 38/32nds of an inch long (1.1875 inches). Longer staple commands a price premium because it produces stronger, finer yarn.

Strength — measured in grams per tex (g/tex). Higher strength means the yarn is less likely to break during high-speed spinning. Stronger cotton commands a premium, particularly for industrial yarns.

Colour — classified by whiteness and brightness. Cotton white is the top grade. Spotted, tinged, or yellow-stained cotton is discounted. Colour problems typically come from rain damage, frost, or delayed harvest.

Micronaire — a measure of fibre fineness and maturity. Micronaire is measured by air flow through a plug of cotton fibres. A micronaire of 3.5-4.9 is the premium range. Cotton with very low micronaire (immature fibres) causes dyeing problems. Very high micronaire (coarse fibres) is harder to spin into fine yarn.

Each bale’s classing data is recorded and attached to the bale’s identity. When cotton is traded, buyers specify minimum quality thresholds, and the classing data provides objective evidence of what they are buying.

This grading system is what makes US cotton particularly attractive in international trade — buyers in Pakistan, Indonesia, or Bangladesh can order US cotton with confidence that the classing data accurately describes what they will receive.

From Gin to Mill: How Cotton Moves Through Trade

Once classed, cotton bales move into commercial trade through two main channels.

Direct mill sales: Large cotton merchants and cooperatives (like Plains Cotton Cooperative Association — PCCA — or Calcot in California) aggregate bales from thousands of gin operations and sell directly to spinning mills. Sales are negotiated on the basis of classing data — the buyer sees the measurement for each bale before purchase.

ICE futures-based pricing: Cotton is often priced relative to the ICE Cotton No. 2 futures contract. A merchant might offer cotton at “5 cents on” (five cents per pound above) the relevant ICE futures month. The futures price provides the base; quality premiums or discounts adjust around it.

Cotton is shipped internationally in containers. Bales are not suitable for bulk carrier shipping — they would absorb moisture. A standard 40-foot container holds approximately 80-100 cotton bales. The major export origins are the US Gulf, US Pacific Coast, Brazil (Santos), Australia (Brisbane, Sydney), and West Africa (various).

The major import destinations are spinning mills in: Bangladesh, Vietnam, Pakistan, Indonesia, India, and China. These countries have the textile manufacturing capacity to convert raw cotton into yarn and fabric.

ICE Cotton No. 2 Futures: The Global Benchmark

ICE Cotton No. 2 (ticker: CT) is traded on ICE Futures US (originally the New York Board of Trade). It is the global price benchmark for upland cotton.

Key contract specifications:

• Unit: 50,000 pounds (approximately 22.7 metric tonnes, or about 100 bales)
• Quotation: US cents per pound
• Delivery months: March (H), May (K), July (N), October (V), December (Z)
• Deliverable grade: Middling, 1-inch staple, US-grown upland cotton

The December contract is most important — it represents the price for new-crop cotton after the main US harvest. The July contract captures the tail end of the old crop.

CT has shown extreme volatility over the years:

• 2011 peak: approximately 215 cents per pound — a 140-year high driven by global supply shortages and speculative demand
• COVID low (2020): approximately 50 cents per pound
• 2022 drought spike: approximately 150 cents per pound (Texas drought destroyed much of the US crop)

This volatility creates significant pricing risk for garment brands that lock in orders months in advance. Raw cotton typically represents 30-50% of the cost of a basic T-shirt.

Price Drivers: What Moves the Cotton Market

Several distinct forces drive cotton price volatility.

Weather in Texas: Texas produces roughly half of US cotton in most years. West Texas in particular is dry, semi-arid farming land where drought is a constant risk. A hot, dry June-July in west Texas can destroy the cotton crop and alone push global prices up by 20-30 cents per pound.

Chinese import demand: China is the world’s largest cotton importer. When Chinese textile mills increase purchasing, they move global prices. When China releases state cotton reserves onto the market, they push prices down. Chinese cotton policy is closely watched by every cotton merchant.

Indian export policy: India periodically restricts cotton exports to protect domestic textile mills. These restrictions, sometimes imposed abruptly, disrupt trade flows and spike prices for countries dependent on Indian cotton.

The durum/soft wheat parallel — the cotton/polyester spread: Cotton competes directly with polyester for a large portion of textile demand (see below). When polyester prices rise (driven by crude oil prices), cotton demand typically rises. When polyester is cheap, cotton’s market share is under pressure.

The durum/soft wheat parallel — CWAD quality premium: The premium between high-quality US cotton (well-classed, good colour, long staple) and low-quality off-grade cotton has widened in recent years as fast fashion supply chains increasingly prefer consistent, documented quality.

Polyester Competition: Cotton’s Biggest Long-Term Rival

Cotton’s long-term market share has been declining. In 1980, cotton accounted for roughly 60% of global fibre production. Today that share is approximately 25-28%. Polyester has taken the rest.

Polyester is made from petroleum derivatives (primarily ethylene glycol and terephthalic acid). It is cheaper per unit weight than cotton in most market conditions, wrinkle-resistant, quick-drying, and easy to blend with cotton for specific performance characteristics.

The price relationship between cotton and polyester matters because textile mills make substitution decisions at the margin. If cotton costs 80 cents per pound and polyester costs 50 cents per pound, mills will use maximum polyester and minimum cotton in their yarn blends. If cotton falls to 65 cents and polyester stays at 50 cents, the economics shift slightly toward more cotton.

Polyester production costs are linked to crude oil. When crude oil spikes, polyester prices follow, making cotton relatively more attractive. When crude is cheap, polyester is cheap, and cotton demand softens.

The other dimension: consumer preference for natural fibres creates a structural floor for cotton demand, particularly in premium garments, home textiles, and markets where synthetic labelling requirements are strict. The “cotton feel” preference means cotton will not be fully displaced by polyester — but its market share trajectory has been persistently downward.

Xinjiang Cotton: Supply Chain Implications

Approximately 85% of China’s cotton production comes from Xinjiang, a region in northwest China. Xinjiang cotton has been at the centre of a major supply chain controversy since 2021.

The US Uyghur Forced Labor Prevention Act (UFLPA), signed into law in December 2021, created a rebuttable presumption that any goods produced wholly or in part in Xinjiang — including cotton and textiles — are made with forced labour and are therefore banned from importation into the United States. The burden of proof is on the importer to demonstrate that goods are not made with forced labour.

The practical supply chain implications are significant:

1. Traceability challenges: Cotton from Xinjiang enters the global supply chain at multiple points — it may be spun into yarn in China, woven into fabric in Vietnam, cut and sewn in Bangladesh, and exported to the US. Tracing cotton fibre back to its origin through four or five manufacturing steps requires detailed documentation that most supply chains did not previously maintain.

1. Fibre testing technologies: Isotope testing and DNA-based testing (such as Oritain and Applied DNA Sciences) can now verify cotton origin at the fibre level. These technologies are increasingly required by brands sourcing for the US market.

1. Supply chain restructuring: Major apparel brands (including H&M, Burberry, Nike, and others) publicly committed to not sourcing Xinjiang cotton. Some shifted sourcing to India, Brazil, Australia, and the US, pushing up demand for cotton from these origins.

1. Price implications: Certified “non-Xinjiang” or “traceable” cotton commands a premium over uncertified cotton for supply chains serving the US and EU markets.

The Xinjiang issue illustrates a broader principle: commodity supply chains that once prioritised only price and quality now must address origin traceability as a commercial and legal requirement.

Downstream Manufacturing: Spinning Mill to Garment

Cotton’s journey from raw fibre to finished garment involves several distinct manufacturing steps, each typically performed by specialist companies in different countries.

Spinning converts raw cotton fibre into yarn. Spinning mills use ring spinning or open-end (rotor) spinning equipment. Cotton bales are opened, blended, carded (aligned), drawn (thinned), and twisted into yarn of specified count (fineness). Bangladesh, India, Pakistan, Vietnam, and Indonesia have large spinning industries.

Weaving or knitting converts yarn into fabric. Woven fabrics (twill, plain weave, satin) are made on looms. Knitted fabrics (jersey, interlock) are made on circular or flat knitting machines. China, Taiwan, South Korea, and India are major fabric production centres.

Dyeing, printing, and finishing processes convert grey (undyed) fabric into finished fabric with colour, patterns, and surface treatments. This is often the most chemically intensive step and has significant environmental implications (wastewater, chemical use).

Cut, make, trim (CMT) is the final garment manufacturing step — cutting fabric to pattern pieces and assembling them. Bangladesh, Vietnam, Cambodia, and Ethiopia are major CMT centres for global brands.

The cotton price seen in the ICE futures market is only the beginning of the cost stack. By the time raw cotton becomes a garment on a shop floor, it has passed through five or six value-adding steps, each with its own labour, energy, and logistics cost. The cotton fibre itself may represent only 10-20% of the final garment’s retail price.

Frequently Asked Questions

What is the ICE Cotton No. 2 contract?

ICE Cotton No. 2 (CT) is the global futures contract for upland cotton, traded on ICE Futures US. It is quoted in US cents per pound for 50,000-pound contracts (roughly 100 bales). The contract specifies Middling grade, 1-inch staple, US-grown cotton for delivery at designated warehouses. It is the benchmark reference price for cotton traded globally.

Why is Texas so important to global cotton prices?

Texas produces roughly 40-50% of the US cotton crop, making it the single most important state for US production. The US is one of the world’s top two or three cotton exporters. A drought in west Texas — which is semi-arid and drought-prone — can destroy a large share of US production and immediately tighten global export supplies, pushing ICE CT futures sharply higher.

How does polyester affect cotton prices?

Polyester competes directly with cotton in blended and pure synthetic textiles. When crude oil is cheap, polyester production is cheap, and mills substitute polyester for cotton to reduce costs. When crude oil rises, polyester becomes more expensive, boosting cotton’s relative competitiveness. The price spread between cotton (cents/lb) and polyester (also tracked in cents/lb equivalent) is a key metric for cotton market analysts.

What is Pima cotton and why is it more expensive?

Pima cotton is an extra-long staple variety grown in the US (Arizona, California, New Mexico, Texas), Peru, and Australia. Its fibres are longer than standard upland cotton (1.4+ inches versus 1.0-1.3 inches for upland). Longer fibres spin into finer, stronger, smoother yarn, which is used in premium products like luxury shirts and high-thread-count bedding. Pima typically trades at a 50-100% premium to standard upland cotton.

What is the UFLPA and how does it affect cotton trade?

The Uyghur Forced Labor Prevention Act (UFLPA) was signed into US law in December 2021. It creates a legal presumption that goods produced wholly or in part in China’s Xinjiang region were made with forced labour and are therefore banned from US import. Importers must provide substantial evidence to rebut this presumption. For cotton, this means supply chain documentation proving the cotton in a garment did not originate in Xinjiang — a significant compliance challenge for complex multi-country supply chains.

How is cotton bale weight standardised for international trade?

A standard US cotton bale weighs approximately 480 pounds (218 kg). Bales from other countries differ: Indian bales are typically around 170 kg; Pakistani bales around 170-175 kg; Brazilian bales around 200 kg. When trading internationally, bale weights and moisture allowances must be specified and reconciled, since invoice prices are typically in cents per pound of actual fibre weight.

Key Takeaways

• Upland cotton accounts for over 90% of global production and is the standard commercial grade; Pima and Egyptian ELS cotton are premium varieties traded at significant premiums.
• India, China, the US, Brazil, and Pakistan are the world’s five largest producers; China is also the largest importer because its textile sector far exceeds its domestic crop.
• Ginning separates fibre from seed; the gin is the entry point for commercial cotton trade, and the seed is a valuable by-product (cottonseed oil and meal).
• USDA cotton classing grades every bale by staple length, strength, colour, and micronaire — this documented quality system underpins US cotton’s premium reputation in international markets.
• The ICE Cotton No. 2 (CT) futures contract in cents per pound is the global price benchmark; the market has shown extreme volatility including a 215 cents/lb high in 2011 and sub-50 cents/lb lows in 2020.
• Polyester, made from crude oil derivatives, competes directly with cotton in textiles; polyester now accounts for roughly 70% of global fibre production versus cotton’s 25-28%.
• The Xinjiang cotton controversy (UFLPA) has created significant supply chain compliance requirements for brands and importers serving the US market, driving demand for fibre origin testing and documentation.
• Cotton’s downstream chain runs from spinning to weaving to finishing to CMT garment assembly — the raw fibre represents only 10-20% of final garment retail price.
