Shandong Yuedun Seal Co., Ltd manufactures bolt seals for container security using hardened carbon steel and zinc-plated steel with ABS plastic components. These seals are designed as tamper-evident devices with laser-marked unique alphanumeric codes for traceability. The mechanism provides high shear resistance and is intended for use in international maritime and logistics operations.
The seals conform to the general design principles of ISO 17712 high-security seals, though certification is not claimed. The hardened steel core resists cutting and drilling, while the zinc plating offers corrosion resistance in marine environments. ABS plastic housings provide impact resistance and allow for clear laser marking. The supplier does not specify tensile strength or temperature ratings, but standard industry values for similar seals apply.
These seals are used by customs agencies, port authorities, and global freight operators requiring secure container closure. Buyers typically order in bulk for use in cross-border shipping. Packaging is not specified, but standard practice involves bulk boxes of 500 to 1,000 units. MOQ and lead time are not stated; buyers must confirm these directly with the supplier before placing orders.

Verify that the seals are manufactured with hardened steel cores and zinc-plated casings as described. Request a sample to test the laser marking’s legibility after exposure to moisture and abrasion. Confirm that the locking mechanism deforms permanently under force and cannot be reset. Do not rely on the supplier’s claim of ISO 17712 compliance without an official certificate.
Lead time and MOQ are not listed - contact the supplier directly to confirm production cycles and minimum order sizes. Incoterms are unspecified; negotiate FOB Qingdao or CIF destination based on your logistics network. Payment terms are not stated - request standard options such as T/T or LC. Ensure packaging is labeled with batch numbers and contains a packing list matching the serial ranges.
Upon receipt, inspect seals for uniform color, clear markings, and consistent weight. Conduct random destructive tests on a sample of 5% of the batch to verify shear strength and reusability. Retain test records and compare them with the supplier’s claims. Request a Certificate of Conformance with each shipment, even if not certified to ISO 17712, to support customs and audit requirements.
