Wheat Class: How Quality Changes the Port Price

Two truckloads of wheat from the same field can fetch different prices at the port — and that is not a mistake at intake. Grain quality sets its class, and class directly drives how much a buyer will pay. Let's go through the parameters a lab checks at intake and why they move the grain price.

What a wheat class is

Under the Ukrainian standard, food wheat is split into classes (usually 1–6), where a lower number means higher quality. The top classes go to flour and bread baking, the lower ones to feed and technical use. Moving between classes literally means a different price, so even a small shift in the figures can push a lot into the neighbouring category.

Key quality parameters

The lab assesses a lot on several parameters at once — and the weakest link drags the class down. The main ones are:

• Protein — the main marker of food wheat; higher protein opens up better classes and export contracts;
• Gluten — its quantity and quality drive the baking properties;
• Test weight (natura) — the mass of grain per volume; it reflects how plump and well-filled the grain is;
• Moisture — an excess requires drying and harms storage, so it lowers the price;
• Falling number — an indicator of sprouting; a low value makes grain unfit for flour;
• Foreign and grain admixtures — contamination directly lowers the settlement weight and class.

Food vs feed wheat

If protein, gluten and falling number stay within norm, the grain goes as food wheat and is worth more. If even one critical parameter falls out (sprouting, low protein, high admixture), the lot drops into the feed category with a correspondingly lower price. That is why one field, in different years or even from different plots, can give a completely different result.

Why the intake lab decides everything

It is the analysis at intake that fixes the class and the settlement weight of a lot — this is the point where quality turns into money. A transparent, accurate reading protects the producer from an unjustified downgrade and gives a fair settlement.

The port pays not for «wheat in general» but for the specific figures in the lab report — so it pays to know your grain's quality before you ship.

The GTK terminal in Kiliya on the Danube runs laboratory quality control at intake so that your lot's class is determined accurately and transparently. Knowing the real figures for the grain, a producer from southern Odesa region can work out in advance what port price to expect.
