How documentation, independent testing and supplier due diligence work together to support confidence in gluten-free ingredients.
One of the most common questions we receive is whether ingredients supplied in Australia require a formal "gluten-free certificate" before they can be described as gluten free.
The answer is often more nuanced than people expect.
Rather than relying on a single certificate, confidence in gluten-free ingredients is typically built through a combination of supplier documentation, technical information, manufacturing controls and independent laboratory testing. Together, these measures help demonstrate that an ingredient continues to meet the requirements for gluten-free applications.
The level of verification varies depending on the ingredient, how it is produced and the potential risk of gluten cross-contact. Understanding how these different forms of evidence work together can help manufacturers make informed sourcing decisions and build greater confidence throughout their supply chain.
Is There a "Gluten-Free Certificate"?
One of the biggest misconceptions in the Australian food industry is that every gluten-free ingredient or product should hold a formal third-party gluten-free certificate.
In practice, there is no single universal certificate that confirms an ingredient is gluten free.
Instead, gluten-free verification is achieved through a combination of supplier due diligence, technical documentation, quality systems and laboratory validation. Responsible manufacturers and ingredient suppliers support gluten-free claims using evidence gathered from multiple sources, rather than relying on a single document or declaration.
Depending on the ingredient and its level of risk, this evidence may include Product Specifications, Product Information Forms (PIFs), Certificates of Analysis, allergen declarations, manufacturing information, traceability and independent laboratory testing.
Many producers validate products through independent gluten testing either on every production batch, where higher-risk ingredients are involved, or at defined intervals as part of their ongoing quality assurance program. The frequency of testing depends on the ingredient, its manufacturing process and the level of risk identified through the supplier's quality management system.
Building Confidence Through Multiple Sources
No single document tells the whole story.
Confidence in gluten-free ingredients is typically established by reviewing multiple sources of information together, including:
- Product Specifications
- Product Information Forms (PIFs), where available
- Certificates of Analysis (CoAs)
- Allergen and gluten declarations
- Manufacturing and processing information
- Supplier food safety and quality systems
- Batch traceability
- Independent laboratory testing
Together, these documents provide a more complete picture of an ingredient's suitability for gluten-free manufacturing than any single certificate alone.
Australia's Gluten-Free Standard
Gluten-free standards vary around the world.
In countries such as the United States, Canada and throughout much of Europe, products labelled "gluten free" may contain less than 20 parts per million (ppm) of gluten.
Australia adopts one of the world's most stringent approaches. Foods labelled "gluten free" must contain no detectable gluten under the Australia New Zealand Food Standards Code, meaning manufacturers need a high level of confidence in both their ingredients and manufacturing controls.
This is one reason why many Australian manufacturers place significant importance on supplier documentation, ongoing verification and appropriate laboratory testing when sourcing ingredients for gluten-free production.

Did you know?
Australia adopts one of the world’s most stringent approaches to gluten-free claims. Under the Australia New Zealand Food Standards Code, foods labelled “gluten free” must contain no detectable gluten. In practical laboratory testing, this may be demonstrated by a result reported as “not detected” at a method-specific reporting limit, commonly 5 mg/kg or lower.
Its important to note that this differs from markets such as the United States and European Union, where foods may generally carry a gluten-free claim when they contain less than 20 ppm of gluten.
Our Approach to Verification
At Gluten Free Wholesalers, we recognise that different ingredients present different levels of gluten risk. For this reason, our verification approach is tailored to the individual ingredient rather than applying a single process across every product.
Depending on the ingredient, our assessment may include reviewing Product Specifications, Product Information Forms (PIFs), Certificates of Analysis, supplier declarations, manufacturing information and other relevant technical documentation.
For selected Australian-grown ingredients and higher-risk products, we also engage independent NATA-accredited laboratories to undertake gluten testing as part of our ongoing quality assurance program. Products that have undergone independent laboratory testing may be identified as Gluten Tested (GT), providing customers with an additional level of confidence.
Our objective is simple—to provide manufacturers with high-quality gluten-free ingredients supported by appropriate documentation, independent verification and ongoing quality review.

What About Coeliac Australia Endorsement?
Another common source of confusion is the Coeliac Australia Endorsement Program.
Coeliac Australia operates a voluntary endorsement program for approved finished products. Businesses that participate and meet the program requirements may licence the Coeliac Australia endorsement logo for eligible products.
The endorsement logo can provide consumers with additional confidence when selecting packaged gluten-free foods.
However, it is important to understand that endorsement is separate from the manufacturer's responsibility to ensure products comply with the Australia New Zealand Food Standards Code when making a gluten-free claim.
Products without the endorsement logo may still legitimately be labelled gluten free, provided they meet the applicable regulatory requirements.
Why Verification Matters
For manufacturers, choosing the right supplier involves more than comparing prices or reviewing a single Certificate of Analysis.
Confidence is built through ongoing supplier relationships, consistent product quality, robust technical documentation and verification processes that support long-term reliability.
When these elements work together, manufacturers are better positioned to produce safe, consistent gluten-free products that consumers can trust.
Frequently Asked Questions
Is there a government-issued gluten-free certificate in Australia?
No. Gluten-free claims are supported through compliance with the Australia New Zealand Food Standards Code rather than a government-issued certificate.
Does every gluten-free ingredient undergo laboratory testing?
Testing forms an important part of gluten-free verification. The frequency and approach vary depending on the ingredient, its level of risk and the supplier's quality assurance program. Many manufacturers validate products through independent laboratory testing on every batch or at defined intervals.
What does "Gluten Tested (GT)" mean?
Gluten Tested (GT) identifies selected products that have undergone independent laboratory testing for gluten as part of Gluten Free Wholesalers' verification process.
Does every gluten-free product need Coeliac Australia endorsement?
No. The Coeliac Australia Endorsement Program is voluntary but requires validation for membership. Products without the endorsement logo may still legitimately meet the requirements for a gluten-free claim.
