TamperSeals Group HSS-007 High Security Bolt Seals
The HSS-007 series from TamperSeals Group represents a premium bolt seal designed for maximum cargo protection. It employs a unique metal-on-metal interlocking mechanism that provides a high level of security and complies with ISO 17712:2013 and C-TPAT standards. A notable feature is its 10mm-thick steel bolt, which is harder to tamper with compared to common 8mm bolts. The locking clip is integrated into a grooved metal bush, enhancing durability and resistance to tampering attempts. For traceability, the seals carry correlative serial numbers and identical barcodes engraved on both parts, ensuring you can detect any substitution or replacement during audits.
Ideal applications include shipping containers, trailers, and multi-modal transport where security is critical. The combination of robust construction, traceability, and regulatory alignment makes HSS-007 a strong choice for high-risk routes or sensitive goods. However, the higher material specifications may come with a higher initial cost, so organizations should weigh long-term security benefits against budget constraints.
Amarine Made Bolt Seal (50 pcs)
Amarine Made offers a bulk set of bolt seals that meet C-TPAT and ISO 17712:2013 requirements, with unique serial numbers for each seal. The product emphasizes anti-spin features to deter unauthorized entry and ensure that once locked, the seal remains secure. This makes it well-suited for container shipments that require reliable one-time use seals across large fleets. The 50-piece pack format supports operations with steady demand, reducing the risk of running out of seals during peak shipping cycles.
Consider Amarine Made when you need compliant security in moderate-to-large quantities and want straightforward, dependable performance with clear identification for tracking and auditing. If your operation involves frequent container handoffs across borders, these seals can provide both compliance and ease of use.
Threlaco 120 Pcs Bolt Seals with Print Progression
Threlaco’s bulk pack of 120 bolt seals is designed for large-scale operations that require frequent access control across multiple shipments. The seals feature progressive numbering, enabling precise audit trails and easy reconciliation of shipments. The construction blends metal and plastic to endure varied environmental conditions and provide reliable performance in both domestic and international logistics. The 3.4-inch length strikes a balance for common container door applications, making them versatile for different container types and transport modes.
Bulk availability is a key advantage for high-volume fleets, ports, and freight forwarders. Operators should ensure compatibility with their existing locking hardware and confirm that the packaging and numbering scheme meets internal tracking standards.

Buying Guide: Key Considerations for Shipping Container Seals
- Security level and standards: Look for seals that comply with ISO 17712 and C-TPAT, especially for high-value or sensitive shipments.
- Seal type and material: Bolt seals offer strong tamper resistance; plastic seals are economical and easy to use but may be less secure in extreme conditions.
- Serial numbers and traceability: Seals with unique serial numbers and engraved barcodes support tracking, auditing, and anti-substitution checks.
- One-time use vs. reusable: Most shipping seals are designed for single use, ensuring tamper evidence after removal. Reuse is generally not recommended for container security.
- Environmental durability: Consider seals that withstand temperature fluctuations, humidity, and rough handling, especially for overseas shipments.
- Bulk availability and pricing: For fleets or high-volume operations, bulk packs reduce ordering interruptions and improve inventory control.
- Application and compatibility: Ensure the seal length, bolt diameter (typically 8mm or 10mm), and locking mechanism suit your container doors and locking hardware.
- Color coding and visual verification: Color variants (e.g., yellow, red, orange) can simplify day-to-day checks in busy facilities.
- Regulatory alignment: Align seals with your compliance program to facilitate audits and protect shipments across border controls.
- Brand reliability and support: Choose vendors with documented certifications, clear replacement policies, and responsive customer support.
