Let's keep this practical. We're taking one simple T-shirt and following it backwards. Yes, backwards. Because once you see how many suppliers sit behind even the simplest product, it becomes much easier to understand why supply chain visibility matters for compliance, collaboration and your margin.
Let's choose something simple to start with. A T-shirt. It looks pretty straightforward, right? But follow its journey backwards and things quickly get more interesting. The finished T-shirt might start with your Tier 1 supplier, the factory that cut, sewed and finished it. This is often the supplier you know best, the one receiving your tech packs, answering your questions and sending samples back and forth. Take another step back and you might arrive at the mill that knitted the fabric. Before that, someone spun the cotton fibres into yarn. Keep following the cotton and eventually you reach the farm where it all began.
These steps are what we generally talk about as supply chain tiers. Definitions can vary, but the basic idea is simple: Tier 1 sits closest to the finished product, and as you move upstream, you meet the suppliers behind your suppliers.
Pretty manageable so far. A handful of suppliers and one neat journey from cotton field to T-shirt. Except a T-shirt is not just fabric. There is sewing thread, a care label, perhaps a neck label, a print, or an embroidery. Each with its own journey, with its own suppliers and raw materials behind it. Suddenly that neat little line starts looking more like a network. And that is for a T-shirt. Imagine following every component in that coat you just bought for the autumn weather.
Wait, how does that work? If I don't know the factory making my T-shirts, who am I actually sending the order to? Fashion and apparel production can be set up in many different ways. A lot of production happens far from the brand itself, sometimes across countries, languages and time zones. That is why many brands work with sourcing agents or buying offices that already have strong relationships with factories and know who can make what, at what quality and within which timeframe.
So you might have worked with Company A for years. They receive your orders, samples and questions, but the actual cutting and sewing happens at Factory B. And Factory B might change depending on capacity, price or lead times.
It does not necessarily mean anyone is trying to hide where your products are made. It is simply part of how a very global and historically industry has been built. But it does create an interesting question. If finding the factory that made your finished T-shirt already takes a little digging, what happens when you want to know who made the fabric, spun the yarn or supplied every component?
Okay, so the network of tiers and suppliers gets big pretty quickly. But does it really matter? If the T-shirts arrive on time, look the way you wanted and sell, why do you need to know who spun the yarn or where the fabric was made? For a long time, many brands did not. You placed the order, got the products home, sold them and started all over again next season. But the industry around that process is changing.
Brands are being asked to know much more about what happens before a product reaches them. New regulation is pushing for greater product and supply chain transparency, while retailers, business partners and consumers increasingly expect brands to back up what they say about their products. And much of the information needed does not sit with your direct supplier. It is further upstream, with the mill, spinner, dye house or raw material producer.
With developments such as the Digital Product Passport on the horizon, knowing where the finished garment was made is increasingly only the beginning. The journey behind the product is becoming part of the product story too.
Okay, so compliance is asking us to look further into the supply chain. But some of those requirements are still a little way off. How do you convince management that mapping suppliers is worth the time and resources today? This is where supplier risk management enters the conversation, and suddenly it is not only about preparing for what is coming.
Imagine you have three Tier 1 suppliers. On paper, that looks pretty safe. Then you discover that all three rely on the same Tier 2 supplier for an important component. Three suppliers suddenly become one very real dependency. Or something changes further upstream. A Tier 3 supplier switches a material or process, but you only discover the quality difference when the next sample arrives. Maybe production has already started. Now you are looking at another sample round, delays and costs that quickly find their way into your margin.
Knowing the suppliers behind your suppliers gives you a chance to spot those connections earlier. It helps you see where you are dependent on one source, where a delay could travel through production and where a small change upstream could become a much bigger problem later. So mapping your tiers is not only about being ready when someone asks where your product came from. It is about understanding how your products actually get made, and having a much better chance of protecting the product journey.
Every month, we host a webinar, often in collaboration with our IT solution partners and leading industry brands. The topics vary, but one thing remains the same: we aim to make the fashion industry’s challenges more manageable and share our take on practical, hands-on solutions.
