Food Supply Chains: Conducting Vendor Due Diligence Beyond Tier 1

Written by Erin Bradley | Aug 2, 2022 1:45:00 PM

Many food businesses will conduct thorough checks on their primary suppliers, and occasionally perform an audit of secondary or tertiary suppliers. However, these audits are often not thorough enough to identify key risks. This can lead to increased costs, delays in production and even lawsuits against companies for failure to comply with regulations such as the Consumer Product Safety Improvement Act (CPSIA). 

What is Supplier Due Diligence and why is it so important? 

Supplier due diligence, or SDD, is a process that allows you to evaluate your suppliers, including those in the so-called ‘tier 2’ and below. It allows organisations to understand the potential risks they face with each tier or supplier, so they can make informed decisions when selecting a supplier or managing new risks. The goal of this evaluation is to ensure that your suppliers meet your company’s standards and expectations. To do so effectively, you will need to conduct thorough research into each potential supplier by gathering information from existing databases as well as conducting interviews with representatives from each company. The benefits of such an extensive screening include a reduced risk of fraud (both internal and external) and an increased likelihood of success when entering new markets. 

Tier 1 suppliers are definitely something companies should be investigating thoroughly, but they must also conduct due diligence on any tier 2 or 3 manufacturers as well. Why? Companies often outsource their manufacturing to a third party which can be either an individual or a company. This means that the product you buy may have been made by a supplier who is not directly involved in your food supply chain, but rather by one of many suppliers (with varying degrees of liability) that have been involved in its creation. So, for companies to ensure they are not buying from an unscrupulous manufacturer, it's necessary for them to conduct due diligence on all tiers of their supply chain. The nature of food supply chains can sometimes make it difficult to know exactly where some raw ingredients and materials have come from or how they entered your food supply chain. Many times, they enter via non-chain intermediaries who can be easily manipulated by dishonest parties. In addition, your tier 1 suppliers may not be providing all their supply chain information correctly or honestly because they fear losing the business if they disclose anything that would make them look bad in front of their clients—or worse yet—have their access cut off entirely.  

Closing the information Gap 



When it comes to what information you should be collating and monitoring when conducting due diligence on prospective suppliers, two key aspects should be considered. 1) Risks associated with the ingredient/ product/ service and 2) risks with the specific supplier/provider. 

For instance, some ingredients may present a greater risk than others such as raw meat and other ingredients at considerable risk of adulteration or contamination. Likewise, each supplier will have their own associated risk, this could be related their financial stability, reputation, geographical location etc. On site Food safety audits may be required to verify the validity and effectiveness of food safety programs and processes. By combining assessment results from both the ingredient/product/ service and the supplier, your business can gain new insights that guide vendor selection.  

Although its vital to capture this information during supplier on-boarding, it is equally as vital to conduct ongoing monitoring of compliance with contractual terms and ingredient risk to provide an indication of the supplier’s ability to continually meet requirements and can provide early indication of an impending problems. Second, periodically reassessing risks presented by the supplier can detect developing problems, such as financial instability. The depth and frequency of each dimension is determined by the level of risk presented.  

Closing the information gap also means ensuring suppliers across all tiers are clear about what is expected of them to remain as an approved supplier; And finally, ensuring that the relevant people within your business have visibility over non compliances or impending risks to off-board clients or seek alternative supply routes, as necessary.
