Buying Guide

Choose seal type by threat model

Steel cable seals resist cutting and are good for high‑security needs; aluminum‑lock cable seals balance corrosion resistance and weight for general container use

Verify tamper-evidence features

Look for single‑use designs and visible break points or serialized locking to make unauthorized access apparent during inspection

Check standards and labelling

Prefer seals that reference ISO‑17712 or industry security standards to ensure they meet recognized strength and testing criteria

Balance per-seal cost and pack size

Compare per‑unit pricing across pack quantities to match seal turnover—bulk packs lower unit cost for high-volume operations while smaller packs reduce upfront spend

Consider environmental exposure

Choose galvanized steel or aluminum components if seals will be exposed to salt spray or wet conditions to reduce corrosion and maintain tamper-evidence integrity
