At a Glance
- A small group makes US corn starch: among the corn starch manufacturers and suppliers below, six producers refine corn into starch. The rest distribute, supply or source it.
- Type decides performance: native, modified and pregelatinized starches behave differently under heat, shear and cooling.
- Plant matters as much as brand: some non-GMO native starches from the same producer are made in Europe, so confirm the plant on every quote.
- Grades are not interchangeable: food, pharmaceutical and industrial corn starch need different documents.
- This is a shortlist, not a ranking: the right route depends on type, grade, certification, plant, pack and destination.
What you’ll learn:
You’ll learn who makes corn starch in the US and how to check the plant behind a quote.
You’ll also get the type, grade and RFQ checks that make quotes comparable.
Introduction
A corn starch quote can hide three differences: the starch type, the grade and the plant. Miss one and you can buy the wrong functionality or the wrong paperwork.
The US industry is concentrated. The Corn Refiners Association says its seven member companies represent all of US corn refining.
This guide helps buyers compare corn starch manufacturers and suppliers in the US. It shows who makes the product, where distributors fit and which checks make quotes comparable. Start with your type and grade, then choose a route.

Who makes corn starch in the USA?
Six producers on this list refine corn into starch in the US: ADM, Cargill, Grain Processing Corporation, Ingredion, Primient and Roquette. Their plants sit mainly in the Midwest, in states including Iowa, Illinois, Indiana and Nebraska. Every other company here supplies, distributes or sources it.
How this list was selected
We screened each company against five gates: a first-party source, a stated commercial role, a US delivery route, a stated type or pack, and a quote or documentation path. All eight companies passed. Inclusion is a starting point. It is not a promise of stock, certification or price.
Role evidence last checked: 5 October 2026. Product ranges and certifications change, so confirm them when you issue an RFQ.
Why Elchemy is listed first. Elchemy publishes this guide, so weigh that. We list it first for one reason. With a handful of corn refiners making US corn starch, buyers often want a second source or a specific grade, and that is the role Elchemy plays. It is a sourcing partner, not a corn refiner. The other seven companies follow in alphabetical order. The order is not a ranking by capacity, quality, price, availability or delivery speed.
Where US corn starch is made
The Corn Refiners Association publishes member plant locations. The table pairs those plants with each producer’s corn starch range.
| Producer | US corn-grinding plants (CRA list) | Corn starch range |
| ADM | Confirm with supplier | Native food grade corn starch and Clinton industrial corn starches |
| Cargill | Hammond IN; Cedar Rapids, Eddyville and Fort Dodge IA; Blair NE; Wahpeton ND; Dayton OH | Native, modified, label-friendly and pre-gelatinized starches |
| Grain Processing Corporation | Muscatine IA; Washington IN | PURE-DENT food, pharmaceutical and cosmetic corn starches, plus industrial starches |
| Ingredion | Bedford Park IL; Indianapolis IN; Cedar Rapids IA; North Kansas City MO; Winston-Salem NC | MELOJEL native corn starch and other food and industrial starches |
| Primient | Decatur IL; Lafayette IN; Loudon TN | Corn-derived industrial starches |
| Roquette | Keokuk IA | Starch from the Keokuk corn wet mill |
Native, modified or pregelatinized: which type to request?
Start with the process. Heat, shear and cooling decide which type works. Read native versus modified for the trade-offs.
| Type | What it does | Ask |
| Native, dent corn | Gives viscosity when hot and forms a gel when cool | The grade and whether a non-GMO claim applies |
| Native, waxy corn | More viscous when hot and does not gel on cooling | Confirm waxy, not dent, on the quote |
| Modified | Thinned, stabilized, roll-dried or cold-water-swelling types | Which modification, and the labeling name |
| Pregelatinized | Builds viscosity without cooking | The cold-water performance data |
If you are weighing other starches, see corn versus potato starch.
Check the plant behind the brand
The same producer can make a product at more than one plant, in more than one country. ADM’s listings for its non-GMO native food starches 100 and 115 state that they are manufactured in Europe. Cargill also runs separate European and North American starch ranges.
Ask for the plant of manufacture and the producer of record in writing. Do it for every grade, especially when you need a non-GMO claim.
Who we left out, and why
Four kinds of names appear in search results for corn starch suppliers but not here.
- Tate & Lyle Americas. The Corn Refiners Association lists its US sites as specialty plants that do not grind corn.
- Non-US producers. Directories list many firms outside the US that do not serve US buyers directly.
- Small-pack retail sellers. They serve consumers, not industrial buyers.
- Names we could not verify. Some distributors may be added after review.
Food, pharmaceutical and industrial grade checks
Start with the end use, then request the grade and documents that match it.
| Buyer requirement | What to request | Do not assume |
| Food grade corn starch | FCC documents, a lot COA, and kosher, halal or non-GMO certificates if required | A food grade lot carries every certification |
| Pharmaceutical | NF or USP documents and producer site details | A food-grade lot meets a pharmacopeial standard |
| Industrial corn starch | A specification for viscosity, moisture and the use, such as paper or corrugating | Industrial grade is safe for food use |
| Allergen and gluten claims | A written statement for the exact lot | Every lot carries the same claim |
For application detail, read corn starch for food.
What does a typical native corn starch specification look like?
Ranges below are drawn from published native corn starch data sheets. Buy against your supplier’s current TDS and COA.
| Parameter | Range in published specifications | Why it matters |
| Moisture | About 9% to 13% | Affects flow, storage and the dry weight you pay for |
| pH | About 4.5 to 7.0 | Affects the process and the finished product |
| Ash | About 0.3% maximum | A purity indicator |
| Protein | About 0.4% maximum | Affects color, flavor and clarity |
| Sulfur dioxide | About 10 ppm maximum | A food safety limit on many data sheets |
Pack formats: bag, tote or bulk
Most corn starch in the listings we reviewed ships as bags, totes or bulk loads. Confirm net weight and liner type in writing, because sizes vary.
| Format | Size seen in producer and distributor listings | Best for |
| Bag | 50 lb (Ingredion, ADM, Cargill via Univar) | Trials and small plants |
| Tote | 2,000 lb (ADM industrial grades) | Mid-size runs |
| Bulk truck or railcar | Offered by ADM for industrial grades | Recurring large volume |
Corn Starch Manufacturers and Suppliers to Consider
This is a role-verified shortlist, not a ranking by capacity, quality, price, availability or delivery speed. Elchemy publishes this article and appears first. The other seven companies are in alphabetical order.
| Company | Verified commercial role | What buyers research it for | Ask before RFQ |
| Elchemy | Supplier / sourcing partner | Second source and specific native or modified grades | Which producer, plant and origin apply? |
| ADM | Producer | Native food grade and industrial corn starches | Which plant makes my grade? |
| Cargill | Producer | Native, modified and pre-gelatinized starches | Which plant and type serve my lane? |
| Grain Processing Corporation | Producer | Food, pharmaceutical and industrial corn starches | Which grade and plant suit my use? |
| Ingredion | Producer | MELOJEL native corn starch and other starches | Which plant and claims apply to the lot? |

| Roquette | Producer | Starch from the Keokuk corn wet mill | Which grades ship from Keokuk? |
| Univar Solutions | Distributor | Cargill native corn starch in 50 lb bags | Which plant made the lot? |
Elchemy: corn starch supplier and sourcing partner
Role: supplier / sourcing partner. Elchemy does not run a corn wet mill or a US corn starch plant. It works with manufacturers across more than one origin and quotes US buyers on the starch type, grade, pack and destination they specify. It can confirm the producer, plant and country of origin in writing for each quote. Technical documents, including COAs, are available on request, and availability is confirmed case by case.
Best for: a second source, a specific native or modified grade, or a sample to test before a volume order.
Not the best fit for: railcar or bulk truck volumes direct from a corn refiner.
Request a Sample to test a grade against your current supplier before you commit to volume.
ADM: corn starch manufacturer
Role: producer. ADM lists a native food grade corn starch labeled kosher, halal and non-GMO. Its Clinton industrial corn starches serve paper, corrugating and adhesive uses in 50 lb bags, 2,000 lb totes, bulk trucks and railcars. Its non-GMO native starches 100 and 115 are listed as made in Europe, so confirm the plant for any grade.
Cargill: native, modified and pre-gelatinized starches
Role: producer. Cargill lists native, modified, label-friendly and pre-gelatinized starches for North America, including waxy corn and potato SimPure starches. It also offers a bioindustrial starch range. Ask which of its US plants supplies your lane and which certificates apply to the lot.
Grain Processing Corporation: food, pharmaceutical and industrial starches
Role: producer. Grain Processing Corporation is family-owned and based in Muscatine, Iowa, with plants in Muscatine and Washington, Indiana. It makes corn starches for food, pharmaceutical and cosmetic use under the PURE-DENT name, including NF and USP grades, and industrial starches. Ask which grade and plant suit your application.
Ingredion: MELOJEL native corn starch
Role: producer. Ingredion makes food-grade and industrial starches. Its MELOJEL native corn starch comes from dent corn, meets FCC requirements and is packed in 50 lb kraft bags. Its brand listing shows kosher, halal and non-GMO labeling. Ask which plant and which claims apply to your lot.
Primient: industrial corn starches
Role: producer. Primient was formed in 2022 when Tate & Lyle sold a controlling stake in its Primary Products business to KPS Capital Partners. It makes corn-derived industrial starches for paper, packaging and building, with a Decatur, Illinois heritage that dates back to A.E. Staley. Ask which grade and plant suit your process.
Roquette: Keokuk corn wet mill
Role: producer. Roquette America runs a corn wet mill in Keokuk, Iowa, acquired in 1991. The mill separates corn into starch, protein, fiber and germ. Ask which native starch grades ship from Keokuk and which certificates apply.
Univar Solutions: corn starch distributor
Role: distributor. Univar lists Cargill Gel native dent corn starch in FCC grade, with kosher and halal certification, in a 50 lb bag, including a non-GMO grade. Quotes run through a request form. Because the producer is named per item, ask which plant made the lot before you compare quotes.
Producer or corn starch distributor: which route fits?
Corn starch suppliers fall into two groups. A producer controls the product and the plant. A distributor adds smaller packs, local delivery and grade breadth.
| Decision factor | Producer route may suit | Distributor route may suit | Buyer input |
| Plant and producer of record | Direct plant specifications and change notices | Needs confirming per item | Required plant or origin |
| Volume | Recurring totes, bulk trucks and railcars | 50 lb bags and mixed orders | Annual volume and order size |
| Documents | Plant-specific certificates | Several producers’ documents under one account | Kosher, halal, non-GMO or FCC needs |
| Technical support | Application teams at the producer | Depends on the distributor | Process conditions and trials |
| Region | Plant-to-site freight | Local stock and regional delivery | Ship-to location |
For the wider trade-offs, see manufacturers versus distributors.
What a corn starch supplier needs in an RFQ
- Name the type. State native dent, native waxy, modified or pregelatinized.
- State the grade. FCC, NF or USP, or an industrial specification.
- List certifications. Kosher, halal, non-GMO and an allergen statement, for the exact lot.
- Ask for the plant. Request the plant of manufacture and the producer of record in writing.
- Describe the use. Give the heat, shear and cooling conditions, so the type can be matched.
- List the documents. Request the SDS, TDS and lot COA. Use the supplier-approval checklist for the full review.
- Define demand and delivery. Give first order, annual volume, pack, ship-to location and receiving limits.
Pair the RFQ with these supplier selection checkpoints so every quote is scored on the same evidence.
What changes a corn starch quote
Corn is the main raw material, so corn costs feed through to starch quotes. Starch type, grade, certifications, plant, pack, volume and freight also change the number.
A lower quote can reflect a different type, grade or plant. Ask each supplier to quote the same specification and delivery terms. For price context, see the bulk corn starch guide.
Five sourcing mistakes to avoid
- Comparing quotes on different starch types. A native quote and a modified quote are not comparable.
- Trusting the brand without the plant. The same brand can come from different plants and countries.
- Assuming non-GMO by default. Non-GMO grades carry their own documents.
- Skipping the COA. Read SDS in procurement for what to check, then request the lot COA.
- Relying on one source. Plant outages and freight delays can tighten supply, so qualify a backup early.
Choosing your route: a decision framework
- Choose a producer route (ADM, Cargill, Grain Processing Corporation, Ingredion, Primient or Roquette) if you run recurring volume of a defined grade and can meet account and delivery terms.
- Choose a distributor (Univar) if you need 50 lb bags, mixed grades or regional delivery.
- Choose a sourcing partner like Elchemy if you want a second source, a specific grade and the plant and producer of record confirmed.
Neither route is universally better. Approve the documented product, plant and delivery route, not the label.
FAQs
Who makes corn starch in the USA?
The Corn Refiners Association says its seven member companies represent all US corn refining. The six producers on this list are ADM, Cargill, Grain Processing Corporation, Ingredion, Primient and Roquette. Plants sit mainly in the Midwest, so confirm the plant and producer of record on every quote you receive.
What is the difference between native and modified corn starch?
Native corn starch is unmodified. Modified starch is treated for stability, such as thinned, stabilized, roll-dried or cold-water-swelling types. Pregelatinized starch builds viscosity without cooking. Match the type to your heat, shear and cooling conditions, and confirm the type on every quote and label.
Is US corn starch non-GMO?
Not by default. Non-GMO grades are sold as specific products with their own documents, such as ADM’s non-GMO native starches and Cargill’s non-GMO dent corn grade. Ask for the non-GMO certificate for the exact lot, and confirm the plant, because some non-GMO grades are made in Europe.
What pack sizes does corn starch come in?
Listings show 50 lb bags, 2,000 lb totes, and bulk trucks and railcars for industrial grades. Bags suit trials and small plants, totes suit mid-size runs and bulk loads suit recurring volume. Confirm net weight and liner type in writing, because sizes vary by producer and grade.
How do I choose between a distributor and a producer?
Choose a producer for recurring large volumes of a defined grade. Choose a distributor for 50 lb bags, mixed grades or regional delivery. In both cases, confirm the plant, the producer of record and the certificates for your lot, so offers can be compared fairly.
What should a corn starch RFQ include?
A corn starch RFQ should state the starch type, grade, certifications, volume, pack and destination. Add a request for the plant of manufacture, the producer of record and the documents you need, including the SDS, TDS and lot COA. This lets every supplier quote the same product on the same basis.
Can Elchemy supply corn starch to US buyers?
Yes, for a defined requirement. Elchemy works with manufacturers and quotes on the starch type, grade, pack and destination you specify, with documents and samples available on request. Share your volume, destination and document needs, and the team confirms availability and commercial fit case by case. Elchemy is a sourcing partner, not a corn refiner.
Conclusion
The safest way to compare corn starch manufacturers and suppliers is to fix the type, grade and plant first, then weigh pack, delivery and a backup source. This eight-company list is a role-verified starting point, not a ranking.
