Tamper-Evident

Tamper-Evident refers to packaging or product design that leaves obvious visible traces if illegally opened or altered, commonly used in exports of food, pharmaceuticals, cosmetics, and high-value goods. In foreign trade, this term often appears in contracts, letters of credit, or quality inspection clauses, requiring suppliers to use tamper-evident packaging (such as seals, security labels, single-use caps) to ensure integrity during transport and sales. Usage scenarios include: customers requesting tamper-evident certification, customs inspection confirming seal integrity, or as a basis for product liability insurance claims. Note: Tamper-Evident is not the same as Anti-Counterfeiting; the former emphasizes 'visible upon opening,' while the latter emphasizes 'authenticity verification'; it is also not the same as Tamper-Proof, which theoretically cannot be opened. Foreign trade practitioners need to specify tamper-evident standards (e.g., ISO 22000, FDA 21 CFR Part 211) in orders and keep sample photos as evidence to avoid returns or claims due to packaging defects.
