Tamper-Proof

Tamper-Proof in foreign trade specifically refers to product packaging or containers having the function of preventing unauthorized opening, tampering, or substitution, usually achieved through one-time seals, anti-counterfeit labels, or special structures (such as break points or snap fits). Use cases include food, pharmaceuticals, cosmetics, electronics, and other high-value or safety-sensitive goods, and it is also commonly seen in 'tamper-evident packaging' required by letters of credit. Notes: It is necessary to clarify whether the tamper-proof requirement is physical anti-opening or anti-counterfeit traceability; different countries/platforms (such as Amazon) have specific standards for tamper-proof packaging; tamper-proof features may increase costs and must be confirmed with the customer; unlike 'Anti-Counterfeit,' which focuses on authenticity verification, tamper-proof emphasizes preventing opening or substitution in transit. Difference from 'Sealed': sealing only ensures initial closure, while tamper-proof ensures that once opened it cannot be restored. Foreign trade contracts should specify tamper-proof standards, test methods, and liability allocation.
