A credible claim such as the MSC blue fish tick label independently verifies that your seafood comes from a sustainable source. Find out how to show your commitment to certified sustainable seafood.

What is a credible claim?

According to ISEAL, the global membership organisation for credible sustainability standards, credible claims are clear, accurate, and relevant, and are backed up by systems that are transparent and robust.

Meeting ACCC guidance

The ACCC has released eight principles to guide businesses’ environmental claims. This provides clear guidance for businesses to support credible claims.

"As a well-established and credible certification body aligned to these principles and those set out by the United Nations, we stand ready to work with businesses throughout the seafood supply chain to assist with mandatory ESG reporting, eliminate consumer confusion and tackle some of the pressing environmental challenges facing humanity." - Anne Gabriel, MSC Program Director, Oceania and Singapore

How are claims verified?

But not all claims are equal. How they are verified is important. 

Seafood products can pass through long and complex supply chains between the ocean and reaching consumers. At each stage, there is a risk that products will be mislabelled or that products from an MSC-certified fishery will be mixed up with non-certified products.

Certification to the MSC Chain of Custody Standard ensures an unbroken chain where certified seafood is easily identifiable, is separate from non-certified products and can be traced back to another certified business. 

This system allows businesses and consumers to be confident that seafood with the blue MSC label has come from a fishery certified as sustainable. 

Claim verification ranked from least to most robust:

  • Claim is not verified: this is where no benchmark or measurement is made, such as “We care about the ocean.” Or “Planet-friendly” OR “Ocean-friendly.”
  • Self-assessed: mostly this includes claims and logos made by the brand or retailer, such as “All our seafood is responsibly sourced.”
  • Interested party verified: this is where an interested party such as a trade body makes a blanket claim, such as “All Australian fisheries are sustainable.”
  • Third-party verified: this is where a claim from an independent third party is used, such as “This product comes from a fishery that has been independently certified to the MSC’s standard for a well-managed and sustainable fishery. www.msc.org.”

The benefits of using a credible claim

  1. Seafood with the blue MSC fish tick can be traced back to a sustainable source. Independent surveillance audits and DNA testing prove this.
  2. The blue MSC fish tick represents the world’s most recognised and market-leading seafood certification scheme as endorsed by GSSI and the UN FAO.
  3. Research shows consumers most trust scientists and NGOs to tackle ocean health and independent certification increases consumer trust in brands.

The MSC claim

The MSC claim accompanies the MSC blue fish tick label and Chain of Custody code on menus and packaging and is available in five versions.
