Oil Stain

Oil stain in foreign trade specifically refers to the defect of oil marks, grease, or other oily dirt on the surface of goods, packaging, or transport vehicles. It is commonly found in the inspection of textiles, leather, paper, metal products, etc., and is a frequent cause of quality claims and returns. Usage scenarios include: contract quality clauses (e.g., 'no oil stains allowed'), letter of credit soft clauses (e.g., 'oil-stained goods rejected'), pre-shipment inspection reports, claim letters, etc. Notes: 1. The definition and acceptable degree of oil stains should be clearly specified to avoid subjective disputes; 2. Distinguish 'oil stain' from 'oil spot' and 'stain'—the former specifically refers to grease, while the latter has a broader scope; 3. Under FOB/CIF, if oil stains existed before shipment, the seller is responsible; if they occur during transport, the carrier may be liable; 4. It is recommended to stipulate inspection standards and sampling methods in the contract. Unlike 'damage' and 'water stain', oil stain emphasizes grease contamination and often requires chemical cleaning, which is costly.
