Just about every supply chain involves commodities. And it is in commodities where many supply chain challenges emerge.
By the strictest definition, commodities are essential raw materials like grains, minerals, fish, livestock, metals, and fruits. Commodities are basic items that are typically the same wherever they may be sourced or how they are processed. One could mine gold from South America or Australia and there would be no difference. The same for sardines, cotton, and palm oil. (Traders would argue that crude oil from Venezuela is much different from crude oil drilled from Saudi Arabia such that petroleum executives would treat either as separate commodities).
What also would qualify an item as a commodity is if it were traded frequently such as in real-time from one minute to the next. Buyers and sellers haggle and firm up contracts, but not only to buy quantities needed to manufacture products but also to bet and hedge for the purpose of either selling at higher prices in the future or to stock up inventories at the lowest cost.
Availability is a constant concern when it comes to commodities. One anticipates scarcity but exploits abundance. Rice prices rose in August and September 2023 due to restrictions in supply. They rose again in 2026 due to increasing costs spurred by higher prices of diesel fuel. Bumper crop harvests of rice in Vietnam and Thailand, however, gave buyers leeway to negotiate lower prices as sellers became worried about selling all of what they bought.
Supply chain managers contend with uncertainties in commodity prices and availabilities, which make it hard for them to set budgets, manage inventories, and ensure enough supply of critical materials for their enterprises’ operations.
Commodities also fray supply chain relationships.
Ranchers in the United States in 2025 intentionally reduced their cattle populations to keep beef prices from dropping. Reduced deliveries of cattle, however, led to shutdowns of meat processing plants, resulting in worker layoffs. Larger meat companies opted to source and import beef from Brazil and Argentina to maintain supply. American ranchers protested but the meat companies ignored them, their feelings already hurt by the ranchers’ unwillingness to boost their cattle herds.
Supply chain managers try to avoid speculation and instead focus on just procuring just enough for their respective operations. They work within the system and use familiar tactics like building inventories or seeking new supply sources for the commodities or raw materials they need. They even try to substitute commodities with other ‘cheaper’ commodities, hoping that they could secure steady supply on top of saving money.
Supply chain engineers (SCEs) on the other hand don’t work within systems; they improve, if not build them, along with the structures that come with them. SCEs plan and construct systems & structures to improve how commodities are procured, transported, and utilised in the manufacture of merchandise. SCEs can be very instrumental in boosting the productivities of operations which are directly dealing with commodities.
For example, the corporate owners of a large plantation did not know for certain how many ripe pineapples they could harvest. There would be days that the corporation’s cannery would have more than enough pineapples for production of canned fruit products. And there would be days that there would be scarce supply which would lead to cutbacks in scheduled operations.
SCEs offered plantation managers a forecasting system to predict pineapple harvest yields via historic data. The system included AI-enhanced simulation tools to forecast pineapple harvests to more precise ranges such that operations managers could draft production schedules in advance to smoothly match the expected arrival quantities of pineapples.
SCEs also identified opportunities for the pineapple cannery to improve operational structures. They proposed, for example, the ideal number of unloading docks to speedily receive newly harvested pineapples.
SCEs could also help enterprises simplify the financial & informational flow processes that make importing foreign-sourced commodities quite complicated. A metals importer, for example, found out via an SCE’s flow map that executives were signing several times for the approval of purchase of the same lot of steel coils from China. The SCE recommended a simpler process of purchase and approval which cut down the time to buy and import critical materials. At the same time, the SCE also suggested lower lot-size purchases of imported commodities to spread cash-out payments and even out inventories.
Most raw materials are commodities, and they are subject to frequent price swings and uncertainties in supply. Speculations in commodities don’t contribute to supply chain productivity even if they may lead to windfall profits and high-cost savings.
As much as supply chain managers may manage inventories to mitigate the uncertainties, it wouldn’t hurt to apply some supply chain engineering ideas to improve systems & structures which govern the flows of commodities.
