Certified Doesn't Mean Clean: How to Audit a Supply Chain

You're a sourcing manager for a mid-sized coffee roaster, and you've just been handed a new single-origin lot from Côte d'Ivoire. The label says Fairtrade. The price is right. But your CEO just read an article about child labor on cocoa farms and wants to know: is this actually ethical? How do you answer with confidence?

Here's the uncomfortable truth: certification is a starting point, not a finish line. The evidence is clear—certified cropland covers only about 1.1% of global cropland (Tayleur et al., 2017), and a review in Nature Food concluded that standards often deliver modest economic benefits and don't guarantee system-wide sustainability (Meemken et al., 2021). So what do you do? You dig deeper. You treat transparency as a process, not a badge. And you use the tools that already exist—due diligence frameworks, public data, and a willingness to ask hard questions.

Start with the Basics: Know Your Legal Exposure

Before you even taste the coffee, you need to know what the law requires. If you're selling into the EU, the Corporate Sustainability Due Diligence Directive (CSDDD) is now in force—it entered into force on 25 July 2024, and it applies to large companies with 5,000+ employees and €1.5 billion turnover (European Commission). If you're in the UK, the Modern Slavery Act requires certain businesses to publish annual statements on steps they take to prevent modern slavery (UK Government). And if you're importing into the US, the Uyghur Forced Labor Prevention Act (UFLPA) creates a rebuttable presumption that goods from Xinjiang are prohibited—meaning you need to prove they aren't (US CBP).

This isn't just paperwork. The US Customs and Border Protection enforces forced labor import bans, and as of 2026 there were 58 active Withhold Release Orders and 9 active Findings (US CBP). That means your shipment could be stopped at the border. Know your obligations before you contract.

Look Beyond the Logo: What Certification Actually Covers

Certifications like Fairtrade are valuable, but they're not a guarantee. Fairtrade, for instance, has roughly 2 million farmers and workers in its system, and audits of over 1,500 producer organizations found they met standards 90-98% of the time in eight of nine due diligence areas (Fairtrade International). That's good, but it's not perfect. And coverage is patchy: certified cropland grew 11% per year from 2000 to 2012, yet still only covers 1.1% of global cropland (Tayleur et al., 2017).

So when you see a Fairtrade logo on a bag of cocoa, ask: what exactly is certified? For cocoa, Fairtrade has 398 certified producer organizations, and they produced 711,000 metric tonnes in 2023 (Fairtrade International). But those organizations represent just a fraction of the 6 million people who depend on cocoa farming (Fairtrade International). Certification is a signal, not a full picture.

Ask the Hard Questions: Where Does the Money Go?

Certification premiums are meant to reach farmers, but do they? Fairtrade coffee producers earned €82 million in premiums in 2023, and cocoa producers earned €57 million (Fairtrade International). That sounds great, but then you learn that only 35% of certified coffee is actually sold on Fairtrade terms (Fairtrade International). That means the premium only applies to a third of the crop. So when you buy Fairtrade coffee, you need to confirm that the specific lot you're buying is one of the 35%, not just a coffee that was grown on a certified farm but sold conventionally.

Also, look at the income data. A 2021 study found Ivorian Fairtrade cocoa farmers increased incomes by 85% over four years (Fairtrade International). That's promising, but it's one study. And the Nature Food review cautions that economic benefits are often modest (Meemken et al., 2021). So ask for proof: what's the actual farm-gate price, and what's the Fairtrade Minimum Price vs. the market price? For coffee, the Fairtrade Minimum Price was above the New York C market 33% of the time from 2020 to 2024 (Fairtrade International). That means two-thirds of the time, the minimum price is below market—so the premium is the only real benefit.

Use the Tools: Due Diligence and Public Data

You don't have to reinvent the wheel. The OECD's Due Diligence Guidance (2018) provides a framework for responsible business conduct (OECD). The UN Global Compact, with 20,000+ companies, offers principles for human rights and labor (UN Global Compact). And for minerals, the Responsible Minerals Initiative (founded in 2008) provides a multi-stakeholder approach to due diligence (RMI).

You can also use public data to check for red flags. The Walk Free Global Slavery Index estimates that 50 million people were in modern slavery in 2021, and 27.6 million in forced labor (Walk Free). For agriculture, UNICEF reports that 70% of child labor is in agriculture, and 160 million children are engaged in work that threatens their health (Fairtrade International). Specifically, an estimated 1.5 million children work on cocoa farms in Côte d'Ivoire and Ghana (Fairtrade International). That's a lot, but it's also a reason to support programs like Fairtrade's Child Labour Prevention and Remediation Programme, which has a budget of €450,000 to help cooperatives generate alternative income (Fairtrade International).

Make a Decision: What to Do When You Find a Problem

Let's say your due diligence uncovers that your supplier isn't certified at all. What then? You have options. You can work with them to improve—Fairtrade's model is built on partnership, with farmers and workers governing 50% of the system (Fairtrade International). You can also look for other certifications, like Rainforest Alliance (active in 60+ countries) or the Forest Stewardship Council (160 million hectares certified) (Rainforest Alliance; FSC). But beware of certification fatigue: the Nature Food review found that standards are insufficient to ensure food-system sustainability at scale (Meemken et al., 2021). So you need to go beyond certification.

One practical step: check if your supplier has a living income reference price. Fairtrade has set more than 10 living income reference prices for cocoa, coffee, coconut, and vanilla (Fairtrade International). If your supplier uses these, that's a sign they're serious. If not, ask why.

Quick tip: When you're evaluating a supplier, ask for their audit reports—not just a summary. If they hesitate, that's a red flag.

Conclusion: Transparency Is a Process, Not a Label

The most important thing to remember is this: supply chain transparency is not a one-time check. It's a continuous process of asking questions, verifying data, and being willing to change suppliers if needed. The fact that certification covers only 1.1% of global cropland (Tayleur et al., 2017) should humble any sourcing manager. But the tools exist—due diligence frameworks, public data, and a growing body of research. Use them. Your customers care: 83% are willing to pay more for ethically sourced products (McKinsey & NielsenIQ, 2023). So get it right, and it's good for people, planet, and profit.
