The Sugar Supply Chain Explained: From Cane to Consumer

Sugar supply chain defined The sugar supply chain converts sugarcane or sugar beet into refined sugar through farming, milling, and refining stages before trading, shipping, and distribution deliver it to food manufacturers and consumers. Raw cane sugar trades globally via ICE No.11 futures contracts; refined white sugar trades via LIFFE No.5 (Euronext). Sugar grade is defined by ICUMSA number — the lower the number, the purer and whiter the sugar. Brazil, India, and Thailand dominate cane sugar supply while the EU, Russia, and Ukraine produce beet sugar through a different, simpler supply chain.

Two Feedstocks, Two Supply Chains

Sugar comes from two entirely different plant sources: sugarcane and sugar beet. They produce chemically identical sucrose, but the supply chains differ in geography, processing steps, and the products that reach global markets.

Sugarcane is a tropical grass that grows in Brazil, India, Thailand, Australia, and parts of Africa and the Caribbean. It produces both raw sugar (which must be further refined for most food uses) and, in Brazil, ethanol (as an alternative crop use). The cane supply chain has two stages of processing: milling (to extract raw sugar) and refining (to convert raw sugar to white sugar). These steps are often performed by different entities in different countries.

Sugar beet is a root vegetable grown in temperate climates: the EU (France, Germany, Poland), Russia, Ukraine, and the United States. The critical structural difference: beet goes directly to white sugar without a raw sugar intermediate stage. A beet processing factory (called a factory, not a mill) extracts juice from the beet and processes it directly into refined white sugar in a single facility. There is no internationally traded raw beet sugar — only white beet sugar.

This distinction matters enormously for commodity trade. The ICE No.11 raw sugar futures contract covers cane raw sugar only — there is no equivalent globally traded contract for beet sugar. Beet sugar enters the market as white sugar, competing directly with refined cane sugar.

Feature	Sugarcane	Sugar Beet
Climate	Tropical	Temperate
Key producers	Brazil, India, Thailand	EU, Russia, Ukraine
Processing stages	Milling → Refining	Direct to white
Raw sugar traded?	Yes (ICE No.11)	No
White sugar traded?	Yes (LIFFE No.5)	Yes (LIFFE No.5)

Stage 1: Farming and Harvesting

Sugarcane is planted from cuttings (ratoon cropping allows multiple harvests from a single planting), grows for 12-18 months, and is harvested by cutting the stalks. Brazil’s Center-South region — the world’s dominant sugarcane belt, centered on São Paulo state — harvests between April and November (the dry season). India’s major growing states (Uttar Pradesh, Maharashtra) harvest from October to March.

The crop is perishable. Once cut, sugarcane begins losing sucrose content within hours from enzyme activity and respiration. This means cane must be delivered to a mill and processed within 24-48 hours of harvest. Harvest scheduling and logistics are tightly integrated.

Sucrose content (measured as “pol” or recoverable sugar) varies by variety, soil, weather, and crop maturity. A poor monsoon in India or a drought in Brazil directly affects sucrose yields and therefore how much sugar is produced per hectare — translating immediately into global supply estimates.

Sugar beet is harvested in autumn (September-November in the EU). Like cane, beet deteriorates after harvest, so processing begins immediately and runs continuously until all the beet is processed — the “campaign” typically runs 60-120 days per year.

Stage 2: Milling — Raw Sugar Production

A sugar mill extracts sucrose from crushed sugarcane. The process:

1. Crushing — cane stalks are shredded and passed through heavy rollers that squeeze out the juice. The remaining fibrous material (bagasse) is burned as fuel in the mill’s boilers, making modern mills largely self-sufficient in energy.
2. Juice clarification — the raw juice is heated and treated with lime to precipitate impurities, which settle out as mud. The clarified juice is filtered.
3. Evaporation — the clarified juice is boiled under vacuum to concentrate it into a thick syrup.
4. Crystallization — sugar crystals are induced to form from the syrup by seeding with fine sugar crystals. The mixture (massecuite) is spun in centrifuges to separate crystals from the remaining liquid (molasses).
5. Raw sugar — the output is raw cane sugar: brown, sticky, approximately 96-97% sucrose, with a distinctive molasses smell. This is the form in which cane sugar typically enters international trade.

The byproduct molasses (approximately 50% sucrose) is sold for animal feed, fermentation (rum, ethanol), and industrial uses.

Beet processing follows a different path. Beet is sliced into thin strips (cossettes) and soaked in hot water to extract the juice. The juice is purified through carbonatation (treatment with CO₂ and lime), evaporated, and crystallized directly into white sugar. The whole process happens in one facility. No raw sugar stage, no separate refinery.

Stage 3: Refining — Raw to White

Raw cane sugar — the brown output of a mill — is not the white crystalline sugar that food manufacturers or consumers typically use. It contains residual molasses, color compounds, and trace impurities. Refining removes these.

A cane sugar refinery buys raw sugar (domestically or imported) and processes it into refined white sugar:

1. Affination — raw sugar crystals are washed with a saturated syrup to soften and remove the molasses film.
2. Melting — washed crystals are dissolved in hot water to form a liquid.
3. Clarification — the liquid is treated with phosphoric acid and calcium hydroxide or through carbonatation to remove color and impurities.
4. Decolorization — liquid passes through activated carbon or ion exchange resins to remove color compounds.
5. Crystallization and drying — refined white crystals are grown, separated, and dried.

The output is refined white sugar with very high purity — typically ICUMSA 45 (see below).

Refineries are often in importing countries, not producing countries. This is deliberate: raw sugar attracts lower import duties than refined sugar in many markets (particularly the EU historically), so cane-producing countries export raw sugar and the importing country does its own refining. This protects refinery employment in importing nations.

ICUMSA Grades: What They Mean in Physical Trade

ICUMSA stands for the International Commission for Uniform Methods of Sugar Analysis. The ICUMSA number measures the color of a sugar solution — specifically, the absorbance of light at 420nm wavelength, expressed per unit of sucrose concentration. The lower the ICUMSA number, the purer and whiter the sugar.

ICUMSA Grade	Color	Purity	Typical Form	Common Use
ICUMSA 45	Bright white	Very high (>99.8%)	Refined white	Food retail, confectionery, beverages
ICUMSA 100-150	White	High	Standard white	Industrial food use, general trade
ICUMSA 600-800	Light brown	~96-97%	Raw cane sugar	Refinery input, ethanol
ICUMSA 1200+	Dark brown	Lower	Raw/dark raw	Animal feed, fermentation

In physical trade contracts, specifying the ICUMSA grade is not optional — it defines the product. A buyer importing sugar for a soft drink company needs ICUMSA 45. A refinery buying raw material for processing specifies ICUMSA 600-800. A contract that simply says “sugar” without an ICUMSA specification is incomplete.

ICUMSA 45 is the international standard for premium refined white sugar. It is the grade typically exported from Brazil’s major refineries and is the basis for spot trade in refined white sugar.

ICUMSA 800 raw cane sugar is what a standard Brazilian or Thai sugar mill produces after milling — this is the typical specification for raw sugar exported under ICE No.11 contracts.

Stage 4: Physical Trading — ICE No.11 and LIFFE No.5

Two futures contracts dominate global sugar price discovery:

ICE Sugar No.11 (ICE Futures US, New York) is the global benchmark for raw cane sugar. The contract covers raw sugar with a minimum polarization of 96° (equivalent to approximately ICUMSA 600-800), priced in US cents per pound, with physical delivery options at a range of world ports. Contract size is 112,000 pounds (approximately 50.8 tonnes).

When buyers, sellers, and traders refer to “the sugar price,” they almost always mean the ICE No.11 front month price in cents/lb. Every physical raw sugar contract in the world is priced as a differential to No.11 — “at a premium of 0.50 cents/lb to No.11 May” or “at a discount of 1.20 cents to No.11 March.”

LIFFE Sugar No.5 (Euronext London, also called London White Sugar) is the benchmark for refined white sugar. Priced in US dollars per tonne. Contract size is 50 tonnes. Physical delivery is white sugar of not less than 99.8% sucrose (ICUMSA 45 or equivalent).

Large sugar trading houses — Sucden, Louis Dreyfus, Bunge, Wilmar — use both contracts to hedge physical positions, manage price risk across origin and destination, and finance inventory.

The Raw-White Premium Spread

The raw-white premium (also called the white premium or refining margin) is the price difference between refined white sugar (No.5 price in $/tonne) and raw sugar (No.11 price converted to $/tonne). It represents the cost and margin of refining.

A “normal” raw-white premium historically runs $60-100/tonne, reflecting the actual costs of refining (energy, chemicals, capital, transport). When this spread widens above $100-120/tonne, refining becomes more profitable and refineries run harder, increasing white sugar supply. When it narrows toward $30-50/tonne, refining margins are squeezed.

The spread is driven by:

• Refining capacity relative to raw sugar availability
• Demand for white vs raw sugar in key importing regions (countries with local refineries want raw; countries without want white)
• Beet sugar supply: when EU beet sugar production is high, white sugar prices are pressured relative to raw, narrowing the spread
• Import tariff differentials: markets where raw attracts lower duty than white widen the structural demand for raw sugar trade

For physical sugar traders and importers, the raw-white spread determines the economics of whether to buy raw and refine locally versus buy refined white direct.

Stage 5: Shipping and Distribution

Raw sugar moves in bulk. Standard vessels are Handysize or Supramax bulk carriers (30,000-55,000 DWT). Brazil’s major sugar export ports — Santos, Paranaguá — are the world’s largest sugar export terminals, handling raw sugar for loading into bulk holds (sometimes with liner bag systems to manage moisture and contamination). Sugar has specific requirements: it absorbs moisture readily, tends to cake, and requires properly lined holds.

Refined white sugar moves in both bulk and bags. Bulk movement (in tanker-type or liner-bag bulk carriers) is economical for large volumes. Bagged sugar (50kg, 25kg, or 1kg consumer packs) moves in containers — particularly for markets wanting consumer-ready products.

Key trade flows:

• Brazil → Middle East, North Africa, Bangladesh, Indonesia (raw and white)
• Thailand → Indonesia, Malaysia, China (white and raw)
• India → Bangladesh, Sri Lanka, Malaysia, African markets (white, when export allowed)
• EU → North Africa, Middle East (white beet sugar)
• Australia → Pacific, regional markets

Distribution within importing markets varies from bulk terminals (storage silos, where tankers and bulk vessels discharge) to warehouse distribution for bagged product.

Frequently Asked Questions

Why does raw cane sugar need to be refined before most food use?

Raw cane sugar (ICUMSA 600-800) contains residual molasses, color compounds, and trace impurities from the milling process. Food manufacturers requiring consistent color, flavor profile, and purity for beverages, confectionery, and processed foods need ICUMSA 45 refined white sugar. Some specialty applications (muscovado sugar, raw cane sugar for specialty use) retain molasses deliberately, but these are niche markets.

What is the ICE No.11 sugar price and how is it used in contracts?

ICE Sugar No.11 is the global futures benchmark for raw cane sugar, traded on ICE Futures US in New York. Prices are quoted in US cents per pound. Physical contracts worldwide reference this price as a “flat price” (paying the futures price itself) or “differential” (futures price plus or minus an agreed premium/discount for grade, origin, and delivery specifics).

How does Brazil dominate the global sugar market?

Brazil is the world’s largest sugarcane producer and largest sugar exporter, typically accounting for 40-50% of global raw sugar exports. Brazil’s competitive advantage comes from large-scale production in the Center-South region (São Paulo, Minas Gerais), modern milling technology, and the ability to flexibly allocate cane between sugar and ethanol depending on relative prices. When Brazilian ethanol demand is high (and ethanol prices are attractive), mills divert cane to ethanol, reducing sugar production.

What is the difference between a sugar mill and a sugar refinery?

A mill extracts raw sugar from crushed sugarcane. It produces raw sugar (ICUMSA 600-800) as its primary product. A refinery takes raw sugar as its input and produces refined white sugar (ICUMSA 45) as its output. These are often in different countries — Brazilian mills produce raw sugar; Gulf state, Indian, and African refineries buy that raw sugar and refine it into white sugar for their domestic markets.

Why does India’s sugar policy matter to global markets?

India is the world’s largest sugar producer (competing with Brazil annually) and has a massive domestic market. India’s government heavily regulates sugar — setting minimum prices for cane, controlling mill operations, and periodically banning or subsidizing sugar exports. When India bans exports (as it did in 2023-2024), a major source of supply disappears from global markets, supporting prices. When India subsidizes exports (as it did in previous years), it dumps large volumes onto world markets, depressing prices.

What drives ICE No.11 sugar prices?

The primary drivers are Brazilian production (which depends on cane yield, weather, and the ethanol/sugar split), Indian production (weather, government policy), global demand growth, crude oil prices (which affect ethanol competitiveness and therefore the sugar/ethanol split in Brazil), and currency movements (particularly the Brazilian real — a weaker BRL makes Brazilian sugar cheaper in USD, depressing No.11 prices).

What ICUMSA grade do most food companies specify?

Most food and beverage manufacturers in developed markets specify ICUMSA 45, the premium refined white sugar grade. Industrial buyers in some developing markets accept ICUMSA 100-150 for cost reasons. Confectionery and pharmaceutical applications are particularly strict about ICUMSA 45 or better.

Key Takeaways

• Sugar comes from two different feedstocks: sugarcane (tropical, Brazil/India/Thailand) and sugar beet (temperate, EU/Russia/Ukraine). Beet goes directly to white sugar; cane goes through a raw sugar stage first.
• The cane supply chain has five stages: farming → milling (raw sugar) → refining (white sugar) → physical trading → shipping and distribution.
• ICUMSA number measures sugar purity and color: ICUMSA 45 is premium white (food use), ICUMSA 600-800 is raw cane sugar (refinery input). The lower the number, the purer the product.
• ICE Sugar No.11 (New York) is the global benchmark for raw cane sugar, priced in cents/lb. LIFFE No.5 (London/Euronext) is the benchmark for refined white sugar, priced in $/tonne.
• The raw-white premium (spread between No.5 and No.11 converted to $/tonne) reflects refining costs and margins; it typically runs $60-100/tonne under normal market conditions.
• Brazil controls roughly 40-50% of global raw sugar exports; its decision to allocate cane between sugar and ethanol is the single largest variable in global supply.
• Raw sugar moves in bulk carriers (Handysize/Supramax); white sugar moves in bulk or containers depending on volume and destination market.
