What Is the Difference Between Term Contracts and Spot Procurement for Natural Rubber? What Should Be Considered When Signing a Term Contract?

Mechanism Differences

Term contracts: stable supply, formula-based pricing, and high planning certainty, suitable for continuous procurement with steady volume; major mills usually have a contracting window for term contracts, and missing it means resorting to spot procurement.

Spot procurement: flexible and market-driven, with price and quantity negotiated cargo by cargo; offer validity is very short during violent market swings, and prices may be adjusted monthly even in stable periods.

Term Contract Negotiation Essentials

Pricing benchmark: which public price it is pegged to (futures settlement price, spot index, or official origin quotation), and whether the full-month average, first-half-month average, second-half-month average, or another window is used—different pricing windows yield different actual costs under the same formula.

Premium/discount and adjustment mechanism: whether the premium is fixed or floating, and what conditions trigger an adjustment.

Volume and delivery: monthly quantity, allowable volume tolerance, shipment cadence, and whether designated mill or grade is written into the contract.

Quality and claims: grade standard, COA requirements, time limit for lodging claims, and resolution mechanism.

Procurement-Side Self-Management

During term contract execution, benchmark prices and basis should still be tracked weekly to assess the deviation between formula cost and market spot; ahead of spot procurement, lock in offer validity and adjustment triggers to avoid verbal prices.
