Full title and description

St ISO 17712-2013 — Freight containers — Mechanical seals. This International Standard specifies classification, performance and tamper‑evidence requirements for mechanical seals used to secure freight containers in international transport and intermodal operations.

Abstract

ISO 17712:2013 establishes uniform procedures for the classification, acceptance and withdrawal of mechanical freight‑container seals. It defines three strength/classification levels, test methods for tensile, shear, bending and impact resistance, marking and traceability requirements, and tamper‑evidence expectations for seals used in international commerce.

Scope

Specifies uniform procedures to classify, test, mark and accept mechanical seals used on freight containers and similar transport units. The standard covers types of mechanical seals (bolt, cable, padlock, strap, wire, cinch, label, barrier and others), establishes classification markings (I, S, H), sets mechanical test methods and tamper evidence requirements, and requires manufacturer and independent testing controls for seals placed on the market.

Key topics and requirements

• Seal classification: three classes — Indicative (I), Security (S) and High‑security (H); class marking is required on compliant seals.
• Mechanical tests: standardized tensile (pull), shear, bending and impact tests determine class assignment; high‑security seals must meet stricter thresholds.
• Bolt‑seal diameter qualification: metal components of bolt seals must meet a minimum 18 mm cross‑dimension to reduce removal through worn hasps (pass/fail requirement for compliant bolt seals).
• Tamper evidence: seals must be designed so tampering attempts leave clear visible evidence; Clause 6 defines tamper‑test procedures and manufacturer documentation requirements.
• Marking and traceability: unique, permanent identification (serial/numbering, manufacturer or customer identifiers, classification mark) is required.
• Independent testing and accreditation: manufacturers submit products to ISO/IEC 17025‑accredited laboratories; periodic re‑testing and process audits are expected (testing cadence and normative annex provisions).
• Durability/environment: seals must resist normal transport/environmental stresses (salt, vibration, shock, weather) appropriate to their intended use.

Typical use and users

Used by shippers, freight forwarders, carriers, port and terminal operators, customs authorities, third‑party logistics providers and security‑focused procurement teams to specify and accept mechanical seals for ocean containers, trucks, rail wagons and intermodal equipment. High‑security (H) seals are commonly required for international shipments and for programs such as C‑TPAT or other customs security schemes.

FAQ

Q: What is this standard?

A: ISO 17712:2013 is the ISO International Standard that specifies classification, mechanical test methods, marking and tamper‑evidence requirements for mechanical seals used to secure freight containers.

Q: What does it cover?

A: It covers types of mechanical seals (bolt, cable, padlock, strap, wire, etc.), required mechanical performance tests (tensile, shear, bending, impact), tamper‑evidence criteria, marking/traceability requirements and manufacturer/testing controls to demonstrate conformance.

Q: Who typically uses it?

A: Shippers, carriers, customs and border authorities, port/terminal operators, logistics providers and procurement/specification teams use ISO 17712 to select and verify seals for international and intermodal shipments.

Q: Is it current or superseded?

A: ISO 17712:2013 is the second edition published in May 2013 and replaced ISO 17712:2010. The 2013 edition is the active edition as recorded by ISO (subject to periodic review by ISO).

Q: Is it part of a series?

A: It is maintained under ISO Technical Committee ISO/TC 104 (freight containers) and builds on earlier PAS/ISO documents addressing container seal practices and testing; related standards and normative references (for testing and accreditation) support its implementation.

Q: What are the key keywords?

A: Indicative (I), Security (S), High‑security (H), bolt seal, cable seal, tamper‑evident, tensile test, shear test, ISO 17712:2013, C‑TPAT.
