The Supplier Was Also Supplying Your Competitor. At a Better Price.
Quote from chief_editor on April 12, 2026, 11:14 amYour commodity supplier is also selling to your competitor, often at better terms. How dual-selling creates market disadvantage in physical trading.
A copper cathode trader based in Singapore had been purchasing from a Zambian producer for three years. Average volume: 2,000 MT per quarter, CIF Shanghai, at a premium of $45 per MT over LME cash settlement. The relationship was stable — consistent quality, reliable documentation, no payment disputes. The trader considered this a core supply relationship.
During a routine market call, the trader's Shanghai buyer mentioned receiving a competing offer for Zambian copper cathode from the same producer, through a different trading intermediary, at a premium of $35 per MT — $10 per MT below the trader's purchase price. The producer was selling the same product, from the same plant, to a competitor of the trader's buyer, at a lower price. The trader was paying $45 over LME and competing against material priced at $35 over LME. On 2,000 MT, the $10 per MT disadvantage translated to $20,000 per quarter — not catastrophic, but enough to lose business when the buyer had a cheaper alternative.
The trader confronted the producer. The producer's response was straightforward: they had no exclusivity agreement with the trader, they were free to sell to any party at any price, and pricing varied based on volume, payment terms, and market conditions. The competitor was purchasing 5,000 MT per quarter with 30-day payment terms. The trader was purchasing 2,000 MT per quarter with LC at sight. The producer offered volume discounts to larger buyers. This was not a betrayal. It was commerce.
The Supplier Relationship Is Not What Procurement Trained You to Think It Is
Traders who come from procurement backgrounds often carry an assumption about supplier loyalty that does not survive contact with the trading market. In procurement, a long-term supplier relationship carries implicit expectations: consistent pricing, supply priority during shortages, and a degree of exclusivity within the buyer's market segment. These expectations are sometimes formalized in supply agreements, sometimes enforced by the buyer's purchasing volume, and sometimes simply a function of the procurement culture.
In physical commodity trading, the supplier's incentive structure is different. The supplier is a producer — a mine, a smelter, a refinery, a crusher. Their objective is to maximize revenue across all buyers. They sell to multiple traders, multiple end users, and multiple geographies simultaneously. Each buyer receives pricing based on their own commercial profile: volume, payment terms, destination, and the supplier's assessment of the buyer's alternatives. A trader purchasing 2,000 MT per quarter is a small customer. A trader purchasing 10,000 MT per quarter with a pre-payment arrangement is a large customer. The producer will price accordingly.
The assumption that a three-year purchasing history creates pricing parity with larger or better-funded competitors is an assumption without contractual basis. Unless the trader has an exclusive offtake agreement — rare in commodity trading and typically available only to traders who commit to significant volumes with pre-financing — the supplier is free to sell to anyone, including to buyers who compete directly with the trader's customers, at any price the supplier chooses.
The operational consequence is that traders who rely on a single supplier without contractual protections are exposed to two risks simultaneously: supply risk (the supplier may prioritize other buyers during tight markets) and margin risk (the supplier may offer better pricing to competitors, eroding the trader's competitive position downstream). Managing both risks requires either contractual protection — exclusive offtake, most-favored-customer pricing clauses, volume commitments with price ceilings — or supply diversification, which means qualifying multiple suppliers for the same product and maintaining active purchasing relationships with each.
The Price You Pay Is the Price the Market Will Let You Pay
The deeper issue is that commodity pricing is not relationship-based. It is market-based. A producer selling copper cathode does not price based on how long they have known the buyer or how many dinners they have shared at LME Week. They price based on what the market will bear, what alternative buyers are offering, and what terms the buyer provides. A trader who offers LC at sight is, from the producer's perspective, a more expensive buyer to serve than a trader who offers 30-day open account, because the LC process involves documentation costs, bank fees, and compliance overhead on the producer's side.
The $10 per MT difference in the Zambian copper example was not arbitrary. It reflected a volume discount of approximately $5 per MT (5,000 MT vs 2,000 MT) and a payment terms discount of approximately $5 per MT (30-day open account vs LC at sight). The producer's pricing was rational. The trader's assumption that the relationship would insulate them from competitive pricing was not.
Traders operating in competitive corridors — base metals from Africa, ferro-alloys from South Africa, agricultural commodities from South America — should assume that their suppliers are simultaneously serving their competitors. The question is not whether this is happening. It is whether the trader's purchase terms are competitive enough to secure reliable supply at a price that supports their downstream margins. If the answer requires investigation — if the trader does not know what terms their competitors are getting — then the trader is managing their supply chain with incomplete information and hoping that the supplier's goodwill compensates for the gap.
Hope is not a strategy in physical commodity trading. The suppliers know this. The traders who thrive know it too. The traders who discover it only when they lose a customer to a competitor offering the same product at a better price learn a lesson that procurement training did not cover: in commodity markets, the relationship is the residual, not the primary, determinant of terms. Price, volume, and payment structure come first. Everything else is dinner conversation.
