In business, demurrage is a delay in delivery of a product via delivery truck.[citation needed] When a delay occurs with product delivery, the delivery party can elect to claim a no fault delay by submitting a demurrage charge. Criteria for allowable demurrage, payment conditions, and payment terms for demurrage are typically prenegotiated and accepted by the vendor via contract prior to conduct of business. Some vendors allow free no-cost time for limited hour(s) when demurrage occurs, others do not allow free time for delays.
