Russian wheat is classified by GOST (Russian state standard) into grades 1 through 5, where Grades 1–4 are milling wheat and Grade 5 is feed wheat. Understanding these grades is essential for flour mills — the wrong grade can mean extraction losses, blending costs, or bread quality issues.
Most traded grade internationally: Grade 2 (12.5% protein) — the backbone of Egyptian, Turkish, and Bangladeshi imports. Grade 3 is the budget option for high-extraction blending.

Which Grade Do You Need?
Grade 1 — Premium Hard Wheat
Rare in commercial volumes. Used by mills producing high-protein bread flour or as a blending improver. Most commonly requested by Turkish mills producing for export markets with strict protein requirements (e.g., bread for GCC countries).
- Best for: high-end bread flour, durum wheat substitution in blends
- Availability: limited, requires forward booking
- Price premium: $10–15/MT over Grade 2
Grade 2 — The International Standard
This is what most Egyptian, Bangladeshi, and Indonesian mills buy. 12.5% protein and 25% gluten delivers consistent flour performance for standard pan bread and flat bread. GASC (Egypt's state buyer) tenders are typically for Grade 2 equivalent.
- Best for: bread flour (72–75% extraction), all-purpose flour
- Availability: year-round, large volumes
- Price: international benchmark
Grade 3 — Budget Milling
Lower protein (11–12%) but still milling quality. Many mills blend Grade 3 with Grade 2 (50/50 or 30/70) to manage costs while meeting end-product specs. Popular with high-volume mills in Turkey and North Africa.
- Best for: high-extraction flour (78–80%), blending, biscuit flour
- Strategy: blend with Grade 2 for optimal cost
- Savings: $5–8/MT vs Grade 2
Grade 4 — Low-Protein Milling / Feed Boundary
At the boundary between milling and feed use. Some mills in cost-sensitive markets (parts of Africa, Southeast Asia) use Grade 4 for high-extraction, low-quality flour. More commonly traded as feed wheat at Grade 5 prices.
- Best for: high-extraction flour in low-income markets, blending base
- Availability: seasonal, depends on harvest quality
Key Parameters Explained
Protein Content
The most important indicator for flour quality. Higher protein = more gluten development = better bread structure and gas retention. Measured as % of dry weight. Standard international contracts specify protein ±0.5% tolerance with price adjustment.
Wet Gluten
Measures the actual gluten network forming capacity of flour. Differs from protein: a wheat can have 12.5% protein but only 22% gluten if the gluten quality is poor. Both protein AND gluten should be specified in your contract.
Gluten Quality (IDK Groups)
IDK (deformation index) measures gluten elasticity. Group I = strong, elastic gluten (ideal for bread). Group II = satisfactory. Group III = weak/sloppy gluten. Always specify Group I or I–II in contracts.
Test Weight (Natweight)
Weight of grain per liter, in grams. Higher test weight = plumper kernels = better flour extraction rate. Below 750 g/L, extraction losses increase. Standard contract spec is ≥750 g/L for Grade 2.
What to Specify in Your Contract
For Grade 2 FOB Novorossiysk, a standard quality specification clause looks like:
Milling Wheat Grade 2 GOST 9353-2016: Protein (d.b.) min 12.5%; Wet Gluten min 25%; Gluten Quality Group I–II; Test weight min 750 g/L; Moisture max 14.5%; Foreign matter max 2%; Fusarium max 0.5%; Falling Number min 250 sec.
Add Falling Number (≥250 seconds) to protect against sprouted grain — a common issue after wet harvest seasons.
