ICUMSA 45 Sugar: The Complete Buyer's Guide

ICUMSA 45 is the benchmark grade for white refined cane sugar in international trade. If you're an importer, food manufacturer, or trading house sourcing sugar from Brazil, understanding exactly what ICUMSA 45 means — and how to buy it correctly — is foundational. This guide covers everything from the grading scale to FOB pricing, contract terms, and Port Santos logistics.

What Is ICUMSA 45 Sugar?

ICUMSA stands for the International Commission for Uniform Methods of Sugar Analysis. It's the global body that establishes standardized testing and grading protocols for sugar and sugar products. The number in an ICUMSA grade — 45, 100, 150, 600, 1200 — refers to the color measurement in Reference Unit units (RBU), measured by how much light passes through a solution of dissolved sugar.

Lower numbers mean purer, whiter sugar. ICUMSA 45 — with a maximum color reading of 45 RBU — is the highest commercially traded grade of white refined cane sugar. It is bright white, free of impurities, and meets or exceeds the specifications required for direct human consumption, food manufacturing, beverage production, and pharmaceutical applications in most importing countries.

How the ICUMSA Grading Scale Works

The ICUMSA color scale runs from ultra-refined (low numbers) to raw (high numbers). Here are the grades most commonly traded internationally:

For most importing countries — particularly in the Middle East, Africa, and Southeast Asia — ICUMSA 45 is the minimum grade accepted for food-grade applications. Government tenders in many markets explicitly require ICUMSA 45 certification with third-party inspection.

ICUMSA 45 Physical Specifications

Understanding the full physical specification beyond the color rating is critical when writing a purchase contract. Below are the standard ICUMSA 45 specifications as traded from Brazilian exporters:

Polarization — also called pol — measures sucrose purity. A pol of 99.80° is the minimum for white refined sugar. Most Brazilian ICUMSA 45 will test at 99.85°–99.95°. This matters if your refinery or product specification requires a tighter pol range.

How Brazil Became the World's Leading ICUMSA 45 Exporter

Brazil produces approximately 40% of the world's internationally traded sugar. The country's dominance comes from a combination of geographic scale, climate, and decades of investment in sugarcane agriculture and milling infrastructure — particularly in São Paulo state and the Center-South region.

Brazilian mills have vertically integrated refining capacity, meaning the same mill that crushes cane can produce ICUMSA 45 in a single continuous process. This gives Brazil a cost structure that most competing origins — India, Thailand, Australia — cannot match. Brazilian sugar is consistently priced at or near the ICE London #5 benchmark, which is why it dominates global trade flows.

The Center-South harvest runs from April through November. Sugar inventories are typically highest between July and October, and that is when FOB prices tend to be most competitive. Buyers planning large orders or annual contracts should time negotiations accordingly.

Pricing and Market Benchmarks

ICUMSA 45 sugar from Brazil is priced against the ICE London White Sugar No. 5 futures contract (ticker: LSU). Spot prices fluctuate with weather patterns in Brazil, Indian export policy, and global energy prices (since sugarcane is also used for ethanol production in Brazil, there is an inverse relationship between oil prices and sugar supply).

A typical premium above raw sugar (ICUMSA 600) for refined ICUMSA 45 runs between $50–$90/MT depending on market conditions. When refinery margins are tight, that premium narrows. When global white sugar demand spikes — as happened in 2022–2023 — it can widen significantly.

Buyers should benchmark against the front-month LSU contract and build in freight, insurance (CIF premium), and any applicable import duties when calculating landed cost. Always request an indicative CIF price at your destination port for a complete landed-cost picture.

Shipping and Port Logistics

ICUMSA 45 sugar from Brazil ships exclusively from Port Santos in São Paulo state — the largest and most active agricultural export port in South America. Santos handles the vast majority of Brazil's sugar exports, with dedicated sugar terminals, warehousing, and fumigation facilities.

Sugar is loaded in bulk or in 50kg polypropylene (PP) bags. Most international buyers requesting ICUMSA 45 opt for bagged sugar, which is more appropriate for re-sale to end markets. Big bags (1MT or 1.25MT) are used for industrial buyers who will decant at destination.

A standard 20-foot dry container holds approximately 20–22 MT of bagged sugar (50kg bags). A 40-foot container holds 24–26 MT. For large orders, bulk shipments via Panamax or Handymax vessels can reduce per-unit freight costs significantly — particularly relevant for orders above 10,000 MT.

Typical transit times from Santos: Dubai 20–25 days; Singapore 28–35 days; Lagos 18–22 days; Guangzhou 35–40 days.

Minimum Order Quantities and Contract Structure

For ICUMSA 45 sourced through Claduta Corporation, the minimum order quantity is 5 containers (approximately 6,250 MT per shipment). This reflects the logistics economics of Brazilian sugar exports — smaller volumes are significantly less cost-effective and harder to schedule at Port Santos.

Contracts are typically structured as:

• Spot: Single shipment, price fixed at time of contract signing
• Annual offtake: Agreed volume delivered in monthly or quarterly tranches, price set against ICE benchmark at each delivery
• Blended: Fixed price for a portion of volume, market-indexed for the balance

All contracts include SGS or equivalent third-party inspection at loading. The inspection certificate is issued before the Bill of Lading and forms part of the shipping documentation package.

Payment Terms and Documentation

Standard payment terms for ICUMSA 45 sugar are 30% at contract signing, 70% against Bill of Lading, paid by wire transfer (TT). For orders exceeding 20 containers, Standby Letter of Credit (SBLC) is accepted as an alternative. Documentary Letter of Credit (DLC) is not accepted.

The standard shipping documentation package includes:

• Commercial Invoice
• Packing List
• Bill of Lading (ocean B/L or airway bill as applicable)
• Certificate of Origin (Brazil)
• SGS or equivalent Quality & Weight Certificate
• Phytosanitary Certificate
• Health Certificate
• Fumigation Certificate
• Full Set of Cargo Insurance (CIF shipments)

Halal certification is not required for ICUMSA 45 sugar in most markets (cane sugar is considered inherently Halal), but can be arranged upon request. Kosher certification is also available with advance notice.

Frequently Asked Questions

Is ICUMSA 45 the same as "white sugar"?

ICUMSA 45 is the highest-grade white refined cane sugar traded internationally. The term "white sugar" can technically include lower-grade refined sugars (ICUMSA 100–150). When specifying food-grade white sugar for import or food manufacturing, always specify ICUMSA 45 explicitly in your contract.

Can I get ICUMSA 45 in a grade lower than the 45 RBU maximum?

Yes. Premium buyers can specify ICUMSA 30 or ICUMSA 20 — ultra-refined pharmaceutical grades — though these carry a price premium. For most food and beverage applications, ICUMSA 45 (max 45 RBU) is the appropriate specification.

How does SGS inspection work at Santos?

SGS inspectors attend at the warehouse at loading. They draw representative samples from the lot, test for ICUMSA color, pol, moisture, and ash. Results are issued within 24–48 hours. The SGS certificate is provided to the buyer before or concurrently with the Bill of Lading and is a condition of final payment.

What is the difference between FOB and CIF pricing?

FOB (Free On Board) means the seller covers all costs until the goods are loaded onto the vessel at Port Santos. The buyer arranges and pays for freight and insurance from that point. CIF (Cost, Insurance, Freight) means the seller covers freight and insurance to the destination port. For most first-time buyers, CIF pricing provides a simpler cost comparison.
