Quantity Definition - The Quantity of Commodity

  • Quantity clause is one of the necessary conditions for the conclusion of an import/export contract. United Nations Convention on Contracts for International Sale of Goods requires that the quantity of goods delivered should be identical to that called for in the contract,otherwise the buyer is entitled to reject that portion of goods excessive in quantity, and to claim against the seller if the quantity is found to be less than that called for in contract.

  • Units of calculation include weight, number, length, area, volume and capacity. The quantities of many commodities are calculated by weight. Gross Weight, Net Weight, Conditional Weight, Theoretical Weight, etc.

  • Since quantity terms may be ambiguous, careful definition in the sales contract is very important. The Metric System, British System, U.S. System and the International System of Units are generally used in international trade nowadays. The implementation and popularization of the International System of Units symbolizes the increasing internationalization and standardization of measurement system. But, confusion and misunderstanding on quantity measures is still not uncommon. An American Pound, for instance, is different from a European Pound; similarly, a ton has a different real weight depending on whether it is a short ton, a metric ton, or a long ton.- Quantity Definition

    Metric System: 1 metric ton=1,000 kilograms=1,000,000 grams
    British System: 1 long ton=2,240 pounds=2,240x16=35,840 ounces
    American System: 1 short ton=2,000 pounds=2,000x16=32,000 ounces

    Conversion:
    1 metric ton=0.9842 long ton=1.1023 short ton
    1 long=1.0161 metric ton=1.12 short ton
    1 short ton=0.9072 metric ton=0.8929 long ton
    1 pound=0.4536 kilogram

Quantity Definition - Quantity Clause in Contract

The contractors are usually required to state clearly the quantity of the deal in a contract, expressions like "about","approximately" should not be allowed. However, in practice, there is often a More or Less clause in the contract. This is used because quite often the shipment is over-delivered or under-delivered,esp. for the trading of bulk goods. The following example of More or Less Clause can be used in contract.

  • The seller has the option of shipping 4% more or less on contracted quantity.
  • Goods are packed in new gunny bags containing 100 kgs and each bag shall weight 1.15 kgs with allowance of 0.1 kg more or less.
  • 1,000 metric tons, 5% more or less at seller's option.
  • The seller is allowed to delivery 5% more or less, the price will be calculated as per the unit price stipulated in the sales contract.


From the above-mentioned examples, the buyer and seller should clearly state the quantity delivered in the sales contract. Otherwise,some unexpected disputes may arise from the performance of contract.
