Weight deviation refers to the difference between the actual delivered weight and the weight specified in the contract, usually expressed as a percentage. In foreign trade, for bulk cargo (such as grain, ore, oil, etc.), due to factors like transportation, loading and unloading, and natural loss, it is difficult to achieve exact weight consistency. Therefore, contracts often stipulate an allowable weight deviation range (e.g., ±5%). Usage scenarios include: letters of credit requiring weight certificates, buyers and sellers agreeing on more or less clauses, and discrepancies between declared and actual weights during customs declaration and inspection. Precautions: The deviation range should be clearly stated in the contract; exceeding the range may lead to buyer rejection or claims; deviation affects payment calculation, and it is necessary to agree on pricing based on actual weight or contractual weight; different goods and transportation methods have different tolerances for deviation. Difference from 'more or less clause': The more or less clause is the contractually agreed allowable deviation range, while weight deviation is the actual difference that occurs; difference from 'weight inspection': Inspection is the means to determine deviation, and deviation is the result of inspection. Foreign trade practitioners should pay attention to weight deviation to avoid economic losses or legal disputes caused by excessive deviation.
📝 Examples
1. The contract stipulates that the weight of iron ore allows a deviation of ±3%. The actual weight at the port of arrival is 2.5% less than the bill of lading weight, which is within the allowable range, and the buyer must pay according to the actual weight. (Note: Within the contractually allowed deviation, settlement is based on actual weight.) 2. Due to water evaporation during transportation of bulk soybeans, the weight at the port of arrival shows a 4% deviation, exceeding the ±2% range specified in the letter of credit. The bank refuses payment, and the seller needs to negotiate with the buyer. (Note: Exceeding the allowable deviation may lead to letter of credit refusal, requiring negotiation.)
