AuditDue diligence in complex supply chains

Risk: Get it out of your system

Organisations are taking a more urgent and active approach to responsible sourcing, as customer expectations shift towards a more sustainable mindset and governments and downstream brands insist on greater transparency.

First you need to gather the facts. Do you understand every facet of your global supply chain? Do you have the knowledge you need to make informed decisions when entering new partnerships?

Navigating the maze of competing voluntary and mandatory standards, certifications and practices is the next challenge. Progress relies on a deep appreciation of the regulations, country governance, local reputations and sourcing risks you might encounter.

10 to 25 years practical field experience of every member in our audit team.

What makes TDi different? It’s our deep expertise in raw material supply chains and large, complex infrastructure projects. Our clients – including large auditing firms – trust our auditors for due diligence. As a small team of experts, we bring an exceptional level of detail and quality control to high-risk projects – when you need more than a tick list.


We have a rigorous understanding of the voluntary standards and worldwide framework.

There’s no substitute for experience and local knowledge. Only a handful of experts in the sustainability industry can claim a rigorous understanding of the voluntary standards and assurance systems – and several of them work here at TDi. Our access to a global network of compliance professionals means we can cover all industries at all tiers of the supply chain from mine to retail.

100% success rate…

In projects where our clients have set out to achieve certification of more than a dozen different schemes.

We speak your language

Auditing in complex supply chains often comes down to experience. What’s actually going on? How do you back that up with evidence? Bad news can prove catastrophic for a company’s reputation, so our job is to ensure ‘no surprises’ in the pipeline.

We bring an independent viewpoint

Working with both upstream producers and downstream brands, we bring an independent viewpoint. TDi Audit can help you to assess performance and align your social, environmental and governance practices with the relevant standards, with a combination of audits, due diligence assessments, training and capacity building.
