Not every supplier plays the same role.

Some provide products when they’re needed, invoices are paid and the relationship goes no further than that. It works perfectly well because that’s all either side expects.

Then there are suppliers who gradually become something more.

They begin to understand how the business operates, when demand typically increases and which products are most critical to keep moving. Over time, they’re no longer simply fulfilling orders. They’re helping the business operate more effectively.

That’s often the difference between a supplier and a strategic supplier.

It Starts Long Before Something Goes Wrong

It’s easy to judge a supplier when everything is running smoothly.

Orders arrive on time, stock levels remain healthy and customers receive what they’ve been promised.

The real test comes when something unexpected happens.

A shipment is delayed. Demand suddenly increases. Production falls behind schedule.

Strategic suppliers don’t make those challenges disappear, but they work with their customers to find a way through them. They communicate early, discuss alternatives and look for practical solutions instead of simply reporting that a deadline has been missed.

Those moments build confidence in a relationship that no contract can guarantee.

Understanding the Business Matters

The strongest supplier relationships become more valuable over time because knowledge builds with experience.

A supplier who has worked with the same customer for several years begins to recognise seasonal demand, understand production schedules and appreciate which deliveries are genuinely time-sensitive.

That familiarity often leads to better decisions on both sides.

Instead of treating every order the same, suppliers can respond in ways that reflect how the business actually operates.

Sometimes the Best Answer is “Not Yet”

People often assume a good supplier is the one who always says yes.

In reality, that isn’t always the case.

Sometimes the most valuable supplier is the one willing to have an honest conversation before a problem becomes a bigger one. They might explain that a deadline is unrealistic, suggest a different approach or raise concerns that haven’t yet been considered.

Those conversations aren’t always easy, but they’re usually far more helpful than a promise that can’t be kept.

Most businesses would rather adjust their plans early than find out at the last minute that an order won’t arrive when expected.

Trust Is Built in the Everyday Moments

Strategic supplier relationships don’t usually develop because of one major event.

They grow over time.

A supplier who keeps customers informed when plans change. A quick phone call before a small issue turns into a bigger one. Deliveries arriving when they were promised, week after week. Small moments like these rarely attract much attention on their own, but they slowly build confidence between two businesses.

Over time, that confidence becomes one of the most valuable parts of the relationship.

The Suppliers Businesses Remember

Every supplier plays an important role, but some leave a lasting impression for reasons that have very little to do with price.

They’re the suppliers who are honest when something isn’t going to plan. The ones who communicate early instead of waiting until there’s a problem. The ones who understand how the business operates because they’ve taken the time to build a genuine working relationship.

Price will always matter, and procurement teams will always look for value.

But ask someone to name the best supplier they’ve worked with, and chances are they won’t begin by talking about cost.

They’ll probably remember the supplier who made their job easier when it mattered most.

Speakers at the Chartered Institute of Logistics and Transport South Africa’s ESG Conference held on 23 June 2026 have called on the logistics, transport and supply chain sectors to move beyond ESG compliance and make leadership, skills development and community impact measurable across the value chain. 

Keynote Sets the Tone 

Delivering the keynote address, Dr Andile Sangqu, Chairperson of Transnet SOC Limited, said ESG could no longer be treated as a reporting exercise. He explained that the sector’s response had to be rooted in honesty, leadership and accountability, with particular attention paid to communities that live with the outcomes of logistics decisions. 

“A supply chain that takes value from a community without reinvesting in it is putting its own future at risk,” he said. “We cannot build a strong logistics network on top of struggling communities.” 

Dr Sangqu urged delegates to see skills as a sovereign asset and build capability at every level of the supply chain, from the boardroom to the loading bay. He noted that South Africa has much of the required knowledge in its universities, technical colleges, industry bodies and development finance institutions, as well as experienced logistics professionals. 

“The skills gap in our sector is central. If we do not close it before 2030, we will end up with excellent strategies and no real capacity to deliver them,” he stressed. 

CILTSA President Elvin Harris commented: “Dr Sangqu reminded us that ESG is a leadership responsibility. The quality of conversation and calibre of people in the room shows how seriously South Africa’s logistics community is taking that responsibility.” 

Panel Discussions Provide Rich Insights 

The Funding Panel, facilitated by DP World’s Lauren Rota, explored the tension between green finance availability and the realities facing logistics operators, particularly SMEs navigating thin margins and complex reporting requirements. Panellists included Bernard Vilakazi from Absa; Sashen Singh from Nedbank Limited; Neo Molomo from the Industrial Development Corporation; Shaheed Alli from the Development Bank of Southern Africa and Jonathan McDonald from the South African Freight and Logistics Association. 

The panel agreed that green financing must be integrated into mainstream financial products, and that development finance institutions must signal growth potential by backing early-stage transitions. 

The Talent Panel, moderated by Liesl de Wet from the Road Freight Association’s Green Transport Working Group, made the case that ESG capability is a value to be embedded across organisational culture, rather than a qualification held by a few specialists. Input came from Associate Professor Rose Luke from the University of Johannesburg; Chantal Kading from People Shop; Maphefo Anno-Frempong, CEO of the Transport Education and Training Authority (TETA); Aimee Girdwood of Stories Evolved and Sandile Khoza from the Ethekwini Maritime Cluster. 

Maphefo Anno-Frempong highlighted the need for industry to collaborate directly with TVETs aligned to local economic activity, while Girdwood said visible leadership support is the starting point for meaningful ESG integration. 

Commitment in Action 

Michelle van den Berg from Takealot Fulfilment Solutions detailed the company’s fleet electrification efforts, advising anyone considering a similar transition to “start small, move on data and do not treat the transition as plug-and-play.” 

Fundiswa Mahlanyana from Isuzu Motors South Africa said Africa’s transition pathway must be phased and grounded in local realities. “We need to start with internal efficiencies, deploy technology that fits routes, and invest when the system is ready,” she said. 

The conference, held at the IMM Graduate School, also featured a presentation on efficiency and sustainability by Renko Bergh from CtrlFleet. It was sponsored by Isuzu Motors South Africa, Ctrack Africa, the IMM Graduate School, CtrlFleet and Chery.

Most supply chains are built around one simple objective: getting products from one place to another as efficiently as possible. Cold chain logistics adds another layer of complexity. It’s not enough for goods to arrive on time—they also need to arrive at exactly the right temperature.

For businesses transporting fresh produce, pharmaceuticals, dairy products, frozen foods and other temperature-sensitive goods, even a small change in temperature can have serious consequences. Product quality may be affected, regulatory requirements may no longer be met and entire shipments can be rejected before they ever reach the customer.

That’s why cold chain logistics has become less about reacting to problems and more about preventing them in the first place.

Small Temperature Changes Can Have Big Consequences

Unlike many other types of freight, temperature-sensitive products often have very little room for error. A refrigeration unit that stops working, a trailer door left open for too long or an unexpected delay at a distribution centre can all affect the condition of the goods inside.

The financial impact goes well beyond replacing spoiled stock. Delayed deliveries, insurance claims, customer complaints and damage to long-standing business relationships can all follow when products fail to arrive in the expected condition.

In cold chain logistics, every degree matters because every degree can influence the value of the shipment.

Visibility Changes the Conversation

Not long ago, many businesses only discovered temperature issues once a delivery had reached its destination. By then, there was often little that could be done.

Today, connected sensors and real-time monitoring give logistics teams a live view of what’s happening while goods are still moving. If temperatures begin to drift outside acceptable limits, teams can investigate, contact the driver or adjust the journey before a small issue becomes a rejected load.

The greatest value isn’t collecting more information. It’s having enough visibility to act while the shipment is still recoverable.

The Journey Doesn’t End When the Truck Leaves

Cold chain management doesn’t stop once products are loaded onto a vehicle.

Traffic congestion, vehicle breakdowns, border delays, loading times and unexpected route changes can all affect delivery schedules. The longer products remain in transit, the greater the pressure on refrigeration systems and temperature controls to perform consistently.

That’s why transport planning has become just as important as temperature monitoring. Choosing the right route, planning realistic delivery schedules and reducing unnecessary delays all help protect the integrity of temperature-sensitive goods.

It’s About More Than Saving the Shipment

When a cold chain shipment fails, replacing the product is often only the beginning. Businesses also have to manage disappointed customers, investigate what went wrong and, in some industries, demonstrate that strict temperature standards were maintained throughout the journey.

For suppliers serving supermarkets, hospitals, pharmacies or food manufacturers, consistency is everything. Customers expect products to arrive in the same condition every time, regardless of the distance travelled or the challenges along the route. Maintaining that consistency helps build trust, and in many cases, it’s that trust that keeps long-term business relationships intact.

Every Shipment Leaves Behind Valuable Information

Temperature readings are no longer collected simply to prove that products stayed within the required range. They also provide a clearer picture of how the supply chain is performing from one delivery to the next.

Over time, that information can reveal recurring delays on certain routes, identify locations where temperature fluctuations occur more frequently or highlight opportunities to improve transport planning. Those small insights help businesses reduce risk before it affects the next shipment.

No two cold chain deliveries are exactly the same, but each one leaves behind information that can help make the next journey more reliable. In an industry where even a small change in temperature can have significant consequences, those lessons quickly become one of the most valuable parts of the supply chain.
