In foreign trade, 'Waterproof' is a common specification term in quality clauses, meaning that goods do not allow water to pass through or can resist water penetration under specified conditions. It is used for textiles, electronics, packaging materials, outdoor gear, etc. Note: Waterproof is fundamentally different from Water-resistant—the former means completely preventing water penetration (e.g., IPX7/IPX8 rating or coating treatment achieving impermeability), while the latter only slows water penetration and is not fully waterproof. If a contract specifies Waterproof but the goods only meet Water-resistant, it may constitute non-conformity, leading to claims or returns. Also, test standards (e.g., AATCC 127, ISO 811) and test conditions (water pressure, time) should be specified to avoid disputes due to standard differences. It also differs from 'Water-repellent,' which only repels water on the surface and does not protect against soaking. Therefore, it is advisable to detail waterproof grade, test method, and acceptance criteria in the contract, and retain samples to reduce trade risks.
📝 Examples
1. Contract clause: The seller guarantees that the fabric of the supplied outdoor backpacks meets the Waterproof standard, with a hydrostatic pressure test of no less than 5000mm; otherwise, the buyer has the right to reject the goods. (Note: Specify waterproof grade and test standard as the basis for quality.)
2. Email communication: Please confirm whether this batch of smartwatches meets the IPX8 Waterproof rating, because our customer requires it to be immersible in 2 meters of water for 30 minutes. (Note: Link Waterproof to a specific IP rating to avoid ambiguity.)
