Discoloration refers to an unexpected change in color of goods during transportation, storage, or use, caused by factors such as light, temperature, humidity, oxidation, or chemical reactions. In foreign trade, this term commonly appears in quality clauses, inspection standards, and claim disputes. For example, for color-sensitive products like textiles, plastics, food, and coatings, buyers often require 'no discoloration' or 'discoloration not exceeding the standard sample.' Discoloration differs from 'fading': fading emphasizes color becoming lighter, while discoloration can include any hue change such as darkening, yellowing, or reddening. It also differs from 'color deviation,' which refers to color inconsistency between batches, whereas discoloration refers to the same goods changing over time or due to environmental factors. Note: Contracts should specify discoloration judgment conditions (e.g., light source, time, temperature), allowable range, and testing methods, and retain sealed samples. If a claim arises from discoloration, it is necessary to distinguish whether it is caused by a defect in the goods themselves or by improper transportation/storage, in order to determine liability.
📝 Examples
1. The contract quality clause stipulates: The goods shall not show obvious discoloration under normal storage conditions within 6 months; otherwise, the buyer has the right to request a price reduction or return. (Note: Clarifies the time and consequences of discoloration as a quality assurance clause.)
2. After receiving a batch of plastic products, the buyer found that some products turned from white to light yellow after exposure to sunlight, and filed a claim on the grounds of 'discoloration,' requiring the seller to bear testing and rework costs. (Note: Demonstrates a practical scenario where discoloration serves as the basis for a claim.)
