California & Hong Kong based security seal company with manufacturing facilities in Asia, delivering the most extensive and customizable range of security seals worldwide.
SealGuard is built to make factory-direct sourcing feel simple, reliable, and truly procurement-ready.
Our factories in Asia have over 25 years of manufacturing experience and have produced high-security seals for many of the world's largest cargo, shipping, and logistics operators. We manufacture at scale, with established production systems and a full portfolio of bolt seals, cable seals, and plastic seals designed for real-world operations.
For customers across North America, including the U.S., Canada, and Mexico, we believe you shouldn't have to choose between global-grade quality and factory-direct pricing. You should be able to access both, without the friction that often comes with overseas sourcing.
That's where SealGuard's North America branch comes in.
Based in California, we provide clear communication, responsive coordination, and the technical depth needed to support high-volume programs, from engineering requirement specifications all the way to RFQs, pilot orders, and production.
We also specialize in OEM and private-label programs, helping customers build seal programs under their own brand with customized markings, numbering formats, barcodes/QR codes, and packaging requirements.
Our mission is not to "resell seals."
Our mission is to make high-volume security seal programs easier to source, easier to scale, and easier to trust, while keeping the benefits of factory-direct execution and pricing.
We believe trust is earned through transparency and continuous improvement. Over the years, our factories have welcomed audits and long-term evaluations from tier-one global operators. We take that feedback seriously and continue investing in upgrades across material selection, production, automation, inspection, quality control, and ISO testing, so customers can scale with confidence.
SealGuard exists so customers can move from spec to quote to production with clarity, speed, and confidence. We stay close to the details so customers can stay focused on their operations, knowing their seal program is supported by a team that takes responsibility and is built for scale.
