Hong Kong Professional Security Seals FAQ - Frequently Asked Questions

Below are usage guidelines and procurement advice for plastic seals, bolt seals, and cable seals, helping you choose the most suitable security solution.


📦 Installation and Usage Guide

Q1: How do I correctly install plastic pull-tight seals?

Steps: Insert the pointed end of the seal through the locking hole and pull it tight. When you hear a "click," it indicates that it's locked.
Technical Point: All HX Plastic seals have built-in stainless steel locking mechanisms, which prevent them from being pulled back once locked. Please be sure to record the unique serial number on the seal for tracking purposes.

Q2: What is the difference in usage between bolt seals and cable seals?

Bolt Seals: Suitable for shipping containers, compliant with ISO 17712 standards, and require bolt cutters for removal.
Cable Seals: Offer flexible lengths. We provide 1.8mm standard models and 3.0mm high-security certified models, suitable for logistics vehicles and heavy-duty valve locking, respectively.


🔍 Product Specification Selection (1.8mm / 3.0mm)

Q3: How do I choose seals based on tensile strength requirements?

Tensile Strength Comparison:
Plastic Seals: Approximately 30-50 kg (1.8mm HX-370 Slim recommended for retail tags).
Cable Seals (1.8mm/3.0mm): ≥ 200kg to over 1000kg.
Bolt Seals: ≥ 20,000 N (approximately 2000kg), specially designed for shipping containers.

Q4: Are the seals weather-resistant? Can they be used in cold chain logistics?

Yes. Our products use industrial-grade PP or ABS steel, with an operating temperature range of -40℃ to +80℃. Specifically, the HX-250 series is designed for medical and food cold chains, with excellent low-temperature resistance without becoming brittle.


🎨 B2B Customization and Wholesale

Q5: Can I print my company logo, serial number, or QR code?

No problem. We use high-precision laser engraving to ensure clear and permanent markings. We support sequential numbering and digital QR code tracking management, significantly enhancing your asset security.

Q6: What is the Minimum Order Quantity (MOQ)?

Standard Stock: Small quantities are supported in Hong Kong, with a minimum order of 100 pieces.
Laser Customization: Typically 1,000 pieces (depending on the model).
Factory Bulk Orders: Deep wholesale discounts available for orders of 50,000 seals or more.


🚚 Delivery and After-Sales

Q7: How long does local delivery in Hong Kong take?

Hong Kong Stock Available: Orders will be delivered within 2-3 business days (Kowloon, Hong Kong Island, New Territories). Mainland China and international shipping times depend on the specific logistics method.

Q8: What should I do if I find a tampered seal?

1. Document immediately: Take photos to record the damaged seal's condition and number.
2. Cross-reference records: Verify the serial number against the shipping manifest.
3. Report and handle: If the number does not match or there are signs of tampering, immediately initiate the cargo verification procedure.
