Our high-security Locktainer container bolt seals are the ideal barrier seal for the secure transportation of shipping containers, trucks and trailers during customs movements. Our bolt seals are fully ISO17712 and CT-PAT compliant, offering the highest level of protection for your cargo throughout the world. Our barrier seals are regularly re-tested to ensure continued compliance with ISO17712 certification standards. Our bolt seals are accepted by UK, US and EEC custom authorities; the Locktainer 2020 bolt seal has SSTA certification and is accepted by HMRC in the UK as a suitable customs seal. It is also the only approved barrier seal for EuroTunnel freight. We can supply sequentially numbered items from stock or can offer you a bespoke marked barrier seal with your own organisation requirements.
