Payment Terms in Commodity Trading: What Every Trader Should Know

Commodity trading uses several standard payment term structures, each allocating risk differently between buyer and seller. Advance payment (cash in advance) places all risk on the buyer, who pays before goods are shipped. Letters of credit balance risk by involving a bank guarantee. Documentary collection (Cash Against Documents) provides moderate security through bank-mediated document exchange. Open account places all risk on the seller, who ships before receiving payment.

The choice of payment terms is influenced by the trust level between counterparties, the transaction size, the country risk of both parties, and the competitive dynamics of the commodity market. Sellers in a strong market position (tight supply) can demand more favorable terms, while buyers in a buyer's market can negotiate terms that shift risk to the seller.

Advance payment or deposits are most common in situations where the seller has significantly more leverage — either because the commodity is in high demand with limited supply, or because the buyer has unproven creditworthiness. Typical deposit structures require 10-30% of the contract value before production or shipment, with the balance due upon document presentation.

For buyers, advance payments create exposure to non-delivery risk. To mitigate this, buyers should insist on advance payment guarantees from the seller's bank (which refund the deposit if the seller fails to deliver) or use escrow accounts held by a neutral third party. The cost of these protective instruments is small relative to the security they provide.

Documentary collections (D/P — Documents against Payment, or D/A — Documents against Acceptance) use the banking system to mediate document and payment exchange without a bank payment guarantee. In a D/P transaction, the seller ships the goods and sends shipping documents to the buyer's bank, which releases the documents to the buyer only upon payment. In D/A, the buyer accepts a time draft committing to pay at a future date.

Documentary collections are cheaper and simpler than letters of credit but provide less security because the banks involved have no payment obligation — they merely handle documents. If the buyer refuses to pay, the seller retains the documents but may have goods already in transit or at the destination port, creating a costly logistical problem.

Open account terms, where the seller ships goods and invoices the buyer for payment at a later date (typically 30, 60, or 90 days after shipment), are the most seller-friendly payment terms and carry the highest credit risk. Open account is typically reserved for established relationships with proven payment histories and strong credit counterparties.

Sellers extending open account terms should consider purchasing trade credit insurance from providers like Euler Hermes, Coface, or Atradius. Credit insurance typically covers 80-95% of the invoice value in case of buyer default, providing significant protection at a cost of roughly 0.2-1.0% of insured turnover. This makes open account terms commercially viable even for transactions where the buyer's credit risk is not negligible.
