ICUMSA 45 vs ICUMSA 100: Which Sugar Grade Should You Buy?

ICUMSA 45 is the global benchmark for refined white sugar β€” but ICUMSA 100 costs less and works for many buyers. Side-by-side comparison of color, price, use cases and target markets.

Quick Answer

ICUMSA 45 is the highest-quality refined white sugar in international trade β€” pure white, fully refined, used in retail packs, premium beverages and pharma. ICUMSA 100 is slightly off-white but functionally identical for most industrial uses, and costs $30-$50/MT less.

If your end use is retail consumer packs, premium beverages, confectionery branding or pharma β€” buy ICUMSA 45. If your end use is industrial baking, brewing, animal feed, secondary refining, or low-end retail in price-sensitive markets β€” ICUMSA 100 saves money with no functional drawback.

What ICUMSA Actually Measures

ICUMSA = International Commission for Uniform Methods of Sugar Analysis. The "ICUMSA value" measures sugar color in IU (ICUMSA Units) β€” the lower the number, the whiter and more refined the sugar.

Where Each Grade Fits

ICUMSA 45 β€” best for:
  • Retail consumer packs (1kg, 5kg)
  • Premium beverages (Coca-Cola, Pepsi, premium juices)
  • Confectionery (chocolate, hard candy, fondant)
  • Pharmaceutical syrups and tablets
  • Markets with strict appearance standards (USA, EU, Japan, Middle East retail)
ICUMSA 100 β€” best for:
  • Industrial baking and biscuit production
  • Brewing and distilling
  • Low-end retail in price-sensitive markets (parts of Africa, South Asia)
  • Animal feed and pet food
  • Secondary processing where final product color isn't critical

Why Some Markets Demand ICUMSA 45 Specifically

In retail-driven markets, consumers visually compare sugar bags on the shelf. Even slight off-white tint flagged as "lower quality" depresses sales. So retail brands and large beverage/confectionery companies write ICUMSA 45 into their procurement specs as a non-negotiable.

In contrast, an industrial bakery cares only about polarization and moisture β€” final cookie color comes from caramelization, not the raw sugar.

How to Choose

Buy ICUMSA 45 if:
  • Your buyer specs require it (most retail/branded buyers do)
  • Your destination market expects pure white sugar visually
  • You're entering a premium retail channel
Buy ICUMSA 100 if:
  • Your end-use is industrial or low-cost retail
  • You can save $30-$50/MT Γ— 25 MT/container = $750-$1,250 per container
  • Your customer doesn't write ICUMSA 45 into the spec
For a 100-container annual buyer, choosing ICUMSA 100 over 45 saves $75,000-$125,000 per year.
