Shipping Seals

Common types include bolt seals for high-security containers, cable seals for irregular closures, plastic pull-tight seals for tamper-evidence, and lead or metal seals for traditional sealing; choose based on required security level, closure type, and whether you need serial numbering or tamper-evident features

Key features are tamper-evident design, unique serial or barcode numbering, material strength (steel/cable vs plastic), and tamper-resistant locking mechanisms; higher-value or regulated shipments generally require metal bolt or cable seals with unique identifiers

Prices range by type and security: plastic pull-tight seals are the most economical, cable and lead seals are mid-range, and heavy-duty bolt/metal seals cost more; average price across this category is around $70–$90, with stronger materials and serialization raising cost

Serial numbers or barcodes provide traceability and help verify tamper events or chain-of-custody; they are recommended for valuable shipments or compliance with industry regulations and require recording the numbers when seals are applied and checked

Store seals in a cool, dry place away from direct sunlight and chemicals, keep them in original packaging to prevent damage or deformation, and avoid bending or kinking cables or seals before use

Most tamper-evident seals are single-use and should be cut off with bolt cutters or shears; reusable seals exist but are less secure, so confirm the product specification before attempting reuse and follow manufacturer removal guidance

Look for compliance with relevant standards such as ISO 17712 for high-security container seals when applicable, plus any industry-specific or customs requirements; verify certifications in product specifications or technical data sheets
