Key Points Concerning A Sales Contract A sales contract embodies a set of different terms such as qKey Points Concerning A Sales ContractA sales contract embodies a set of different terms such as quality, quantity, payments, delivery, and insurance, etc. When the exporter and customer are negotiating, they should consider and agree upon these terms. Apparently, each party hopes to stipulate terms favorable for himself. But arrangements which are advantageous to one party are often disadvantageous to the other party. Therefore, some practical suggestions and tactics should be given adequate importance in negotiation of a contract. In this sector, you will have a look on the problems international trade negotiators may face and suggestions in solving them.Name of goodsIt is recommended that the names of goods to be exported correspond to the names used in the customs lists of the importing country, in order to minimize problems at customs, and to facilitate calculation of import duties.The exporter should be consistent in the names he uses for his products, referring to them precisely as he does in the catalogs he gives to the importers, for the purpose of avoiding any trouble of breach of an agreement for nonconforming goods.QuantityIn indicating length, weight, volume and so on, the metric system should be used unless the sale is between countries which use another system.For goods whose quantity could easily decrease during transportation, the biggest issue will be where and when to establish the quantity as a basis of payment and so on. The buyer wants the quantity to be determined upon receipt of the goods at his warehouse, while the seller wants to establish the quantity at the time of shipment at his plant. This issue can be solved only in connection with the closely related issues of risk of loss and insurance.QualityAn order specifying goods as per sample is apt to lead to trouble, because often it is not made clear that a sample is first requested as a basis for future orders, and because it is not always clear just how much deviation from the sample will be tolerated.It is therefore recommended that the quality of goods be specified by specifications or detailed description of samples and that these specifications or descriptions be made a part of the agreement.PriceThe contract price will be closely related to the conditions of delivery, such as FOB, CFR, or CIF. One of these delivery terms will be chosen after consideration of the economic and political factors involved. The problem here is that these terms are not always understood to mean the same thing. For example, in common practice, delivery is deemed completed, and title to the product and the risk of loss pass to the importer, upon shipment. This definition of delivery is called FOB. However, the definition of FOB under Incoterms differs from the definition used in the USA. Therefore, to avoid the problems arising from the different possible meanings of these terms, it is highly recommended that each of these terms, whenever used in an agreement, be defined in it.A drastic change in the foreign exchange rate could absorb all the profit expected from a transaction or could even cause a deficit.
