factor that determines the success of grain exports. It directly affects the price, global market demand, and compliance with international contract requirements. To ensure objective assessment and fair pricing, the global grain industry follows clear standards that classify wheat and other crops. At the core of this system are the Gafta (Grain and Feed Trade Association) rules, which apply to most international contracts.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Quality_Indicators_That_Determine_Wheat_Grain_Class\"><\/span>Quality Indicators That Determine Wheat Grain Class<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Grain quality is a combination of <strong>physical and chemical characteristics<\/strong>, which can either be assessed visually or measured using specialised equipment and laboratory methods. <strong>Physical characteristics<\/strong> (such as colour and grain shape) can be determined by visual inspection, while <strong>chemical properties<\/strong> (such as protein content, moisture level, and gluten quantity) require laboratory analysis. The classification of wheat is based on specific quality indicators, which are strictly regulated by international standards.<\/p>\n\n\n\n<p>Different wheat classes correspond to different <strong>quality levels<\/strong> and <strong>intended uses<\/strong>. The class assigned to wheat directly impacts its <strong>market price<\/strong> and attractiveness to importers.<\/p>\n\n\n\n<p>Key quality indicators of grain include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Test Weight (Natural Weight).<\/strong> This indicator describes the weight of a specific volume of grain, essentially measuring how densely the grain is &#8220;packed&#8221; within a given space. The higher the test weight, the better the grain quality. It is measured in grams per litre (g\/L) or kilograms per hectolitre (kg\/hL). For example, bread-making wheat typically has a test weight of around 750 g\/L (or 75 kg\/hL).<\/li>\n\n\n\n<li><strong>Protein.<\/strong> Determines the <strong>nutritional value<\/strong> of the grain and its <strong>technological properties<\/strong>. For bread-making wheat, protein content typically ranges from 10% to 14%.<\/li>\n\n\n\n<li><strong>Moisture.<\/strong> The amount of water in the grain, which affects its <strong>storage stability<\/strong>. For wheat, the maximum allowable moisture content is usually set at 14.5%.<\/li>\n\n\n\n<li><strong>Gluten.<\/strong> A key indicator of the grain&#8217;s <strong>ability to form dough<\/strong>, which is crucial for <strong>bread production<\/strong>.<\/li>\n\n\n\n<li><strong>Damaged Grains (Broken Kernels or Damaged Kernels).<\/strong> The presence of damaged grains affects both the <strong>quality of the final product<\/strong> and the <strong>grain&#8217;s storability<\/strong>.<\/li>\n\n\n\n<li><strong>Admixture.<\/strong> The percentage of foreign matter that is <strong>not wheat grain<\/strong> (e.g., plant residues, weed seeds, etc.). For bread-making wheat, admixture levels should not exceed 2%.<\/li>\n\n\n\n<li><strong>Specific Quality Indicators for Certain Uses.<\/strong> For example, a key indicator for <strong>bread-making wheat<\/strong> is the <strong>Hagberg Falling Number<\/strong>, which assesses whether the grain has begun to germinate and how well it will perform in baking. This test measures the activity of the enzyme <strong>amylase<\/strong>, which breaks down starch into sugars, making the dough sticky and unsuitable for baking. The <strong>Hagberg Falling Number<\/strong> is measured in <strong>seconds<\/strong> and represents the time it takes for a plunger to sink under its own weight in a starch suspension. <strong>Lower values indicate higher enzyme activity<\/strong>, meaning poorer baking quality. In commercial contracts, a minimum of 220\u2013250 seconds is typically required, though exact requirements depend on national standards and contractual agreements.<\/li>\n<\/ul>\n\n\n\n<p>These indicators directly affect the classification of the grain and determine its market value.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Grain_Quality_Requirements\"><\/span>Grain Quality Requirements<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Grain quality requirements are determined by contract terms, international standards, and the legislation of the exporting country.<\/p>\n\n\n\n<p>Typical criteria include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Moisture content, test weight, protein content, and gluten levels;<\/li>\n\n\n\n<li>Admixture content (including grain impurities and foreign matter);<\/li>\n\n\n\n<li>Compliance with a specific class based on physical and chemical characteristics.<\/li>\n<\/ul>\n\n\n\n<p>The exact specifications depend on the type of grain, its intended use (bread-making, animal feed, pasta production, etc.) and the terms of delivery.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"International_Wheat_Quality_Classification\"><\/span>International Wheat Quality Classification<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>There is <strong>no single international wheat quality classification<\/strong>. Each country has its own standards and classification systems, which may be similar but are not unified. The specific classification applied is often specified in the contract.<\/p>\n\n\n\n<p>Let us examine a few examples of wheat classification. While different countries use their own systems, it is important to understand the common elements in these classifications.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"United_States\"><\/span>United States<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>In the United States, grain classification is regulated by the <strong>Federal Grain Inspection Service (FGIS)<\/strong>.

It ensures objective quality control through a network of accredited inspection agencies.<\/p>\n\n\n\n<p>FGIS provides separate classifications for wheat, maize, barley, and other crops.

The primary document that defines grain assessment rules is the <strong>Official Grain Grading Guide<\/strong>.<\/p>\n\n\n\n<p>CGC classifies wheat based on its functional characteristics (e.g., suitability for bread-making, pasta production, etc.) and growing region. In general, two primary regions are distinguished:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Western Canada<\/li>\n\n\n\n<li>Eastern Canada<\/li>\n<\/ul>\n\n\n\n<p>Each region has multiple wheat classes, with the Official Grain Grading Guide establishing strict quality standards for each.
