Certified Organic Corn and Specialty Grain for Food-Grade Production
SQF Certified, Kosher Certified, and Gluten Free: Every Program, Every Shipment
Our grain programs are built on a foundation of third-party certification and documented quality control. Clark Specialty Grains holds SQF, Kosher, and Gluten Free certifications, and every organic grain lot ships with a current USDA organic certificate, non-GMO PCR test results, and a full pre-shipment certificate of analysis. These are not marketing commitments. They are documented, audit-ready standards applied to every load we ship.
We supply yellow, white, blue, and pink corn varieties to snack producers, tortilla mills, specialty millers, cereal manufacturers, and ingredient distributors who need grain that performs consistently and documents cleanly across every production run. If you are new to specialty grain sourcing, our overview of the health benefits and applications of specialty grains is a useful starting point for understanding what makes certified grain programs worth the investment.
Our Grain Supply Programs: Built Around Your Requirements
Organic, Non-GMO, Identity Preserved, Food-Grade, and Bulk Grain Programs
Every buyer’s grain sourcing need is different. Some require dual-certified organic and non-GMO corn with identity preservation for retail label claims. Others need food-grade bulk supply with rapid lead times and standard COA documentation. We have built specialized programs around the most common sourcing requirements food manufacturers and ingredient buyers face, each with its own quality standards, certification framework, and logistics infrastructure.
Explore Our Specialized Grain Programs
- Wholesale Corn Grains: Certified organic yellow, white, blue, and pink corn in bulk quantities with full documentation for food manufacturing, milling, snack production, and distilling
- Identity Preserved Grains: Lot-level traceability, variety segregation, and chain-of-custody documentation for retail label claims and third-party audit requirements
- Non-GMO Grain Supply: PCR-verified non-GMO sourcing with complete documentation for buyers who need verified GMO compliance with or without full organic certification
- Specialty Corn Varieties: Yellow, white, blue, pink, waxy, and flint corn varieties for differentiated food products where color, starch, or milling performance drives the sourcing decision
- Food-Grade Grains: Multi-stage cleaning, mycotoxin testing, CO2 treatment, and FSMA-aligned documentation for food manufacturers with strict production and regulatory requirements
- Bulk Grain Supply: Truckload, tote, and rail shipping with contracted program options and complete logistics coordination for large-volume manufacturers and distributors
Why Clark Specialty Grains Is a Trusted Specialty Grain Supplier
What Sets a Dedicated Specialty Grain Supplier Apart from a Commodity Vendor
The difference between a specialty grain supplier and a commodity grain broker is visible in the documentation, the handling infrastructure, and the accountability that comes with every load. Clark Specialty Grains is a family-owned operation with direct grower relationships, a certified processing facility, and the quality systems food manufacturers need to source with confidence rather than hope.
Our processing facility uses a multi-stage cleaning system including gravity tables, color sorting with Shape Technology, rare earth magnets, D-stoner, and a Safeline metal detector before final loading. Every organic grain lot is CO2-treated for a no-live-bugs guarantee without chemical fumigants, keeping organic certification intact from harvest through delivery. For a closer look at how this approach supports clean, compliant grain for snack and food manufacturers, see our post on gluten-free grain options and what food-grade handling makes possible.
Core Capabilities That Define Our Programs
- SQF, Kosher, and Gluten Free certified facility handling
- USDA organic certification with annual grower and handler verification
- Non-GMO PCR verification through accredited third-party laboratories
- Identity preservation with lot-level traceability from seed to shipment
- CO2 grain treatment with no-live-bugs guarantee on every organic load
- Contracted supply programs with grower-aligned production for multi-season reliability
- Truckload, tote, and railcar shipping via Union Pacific and BNSF
How We Maintain Grain Quality from Harvest Through Delivery
OPI Automated Storage, CO2 Treatment, and Precision Cleaning for Every Load
Quality assurance at Clark Specialty Grains does not begin at our facility. It begins in the field with grower selection, seed verification, and pre-harvest crop assessment. By the time grain reaches our facility, the quality baseline is already documented. What our processing and storage systems do is protect and verify that baseline before the grain reaches your production line.
Post-Harvest Quality Infrastructure
- OPI automated storage monitoring: Continuous tracking of temperature and moisture conditions across all storage bins to maintain grain stability and prevent quality degradation
- Multi-stage precision cleaning: Aspiration, gravity tables, Forsberg D-stoner, Satake Evo 800 color sorter with Shape Technology, and Safeline metal detection applied to every food-grade lot
- CO2 grain treatment: Complete pest elimination without phosphine or chemical fumigants, maintaining organic certification compliance through delivery
- Pre-shipment laboratory testing: Moisture, test weight, purity, and program-specific parameters confirmed by accredited third-party labs before loading
- Documented lot tracking: Every load ships with COA, organic certificate, non-GMO test results, and traceability records as a baseline documentation package
Understanding how grain is stored between harvest and delivery is an important part of evaluating a supplier. Our post on optimal grain moisture content for storage explains the thresholds we manage to and what happens when grain is held outside the safe range.
Explore Our Full Organic and Specialty Grain Selection
Yellow, White, Blue, and Pink Corn Plus Specialty Grain Species
Our grain portfolio is anchored by certified organic corn in four varieties, each available with identity preservation, non-GMO PCR verification, and food-grade documentation. Beyond corn, we source organic wheat, oats, barley, rye, soybeans, and specialty grains through our grower network based on crop year availability and buyer program requirements.
Whether you are sourcing a specific corn variety for a branded chip product, need identity preserved organic grain for a retail label claim, or require bulk non-GMO verified grain with standard COA support for ongoing production, our team builds programs around your specifications. Browse our complete organic grain supply programs to find the right starting point for your sourcing needs.
The Clark Specialty Grains Difference
Food manufacturers who have experienced a supply chain failure with a previous grain vendor understand quickly that price is rarely the most important variable in supplier selection. Reliability of supply, consistency of quality, completeness of documentation, and responsiveness when conditions change are what actually determine whether a supplier relationship works. Clark Specialty Grains is built around all four. We are a direct sourcing operation with grower relationships, certified facility infrastructure, and the documentation systems that make every load verifiable before it arrives at your dock.
Consistent, Certified Supply for Every Program
We manage sourcing, certification, cleaning, testing, and logistics as an integrated program so your procurement and quality teams receive consistent, documented grain on every order. From contracted annual programs to spot truckloads, our supply infrastructure is built for buyers who cannot afford variability.
A Long-Term Grain Supply Partner, Not Just a Vendor
We invest in grower relationships, facility infrastructure, and buyer communication because supply chain accountability is what separates a dependable partner from a replaceable vendor. When conditions change, we communicate early. When specifications shift, we adapt.
