Development status
Development and certification progress
Samjin LND designs molds and injection-molds plastic hydrogen tank liners. We are pursuing ISO 11119-3 and TPED certification for complete Type 4 transportable tanks incorporating those liners. The certification scope does not cover liners as standalone products. These tanks will not be offered for sale until certification is complete, but we welcome early inquiries and partnership discussions.

Why the liner matters
Why choose a plastic liner?
-40%LighterCompared with a metal liner · Development benchmark
39 years of injection molding and mold expertise
Our mold design and injection molding expertise provide the dimensional precision and material uniformity required at ultra-high pressure. With every process kept in-house, we eliminate quality variation at the source.
Pursuing Type 4 hydrogen tank certification
We are pursuing ISO 11119-3 and European TPED certification for Type 4 transportable hydrogen tanks using our liner. Certification covers the complete tank, not the liner alone.
Development & Certification
Liner development and tank certification schedule.
Liner design validation is complete. We are now preparing for certification of the Type 4 transportable hydrogen tank.

Certification standard for the complete Type 4 transportable hydrogen tanks incorporating our liners.
ScheduledTPED certification scheduled
European Transportable Pressure Equipment Directive (TPED).
Scheduled
TPED
Certification scheduled for April 2027Transportable Pressure Equipment Directive
The EU directive governing transportable pressure equipment. Applicable equipment must meet its conformity assessment requirements before being placed on the EU market.
ADR
Road transport requirementsAgreement concerning the International Carriage of Dangerous Goods by Road
ADR sets requirements for the international carriage of dangerous goods by road, covering both equipment and transport operations.
The π-mark indicates conformity of transportable pressure equipment under TPED. Transport operations must also comply with the applicable ADR requirements.
References to ISO 11119-3 and TPED on this page concern complete Type 4 transportable hydrogen pressure vessels incorporating our liners. They do not indicate certification of the liners as standalone products. Samjin LND designs and injection-molds hydrogen tank liners.
Potential applications
Applications across hydrogen mobility
Once the tank is certified, the liner's applications will expand to mobile storage vessels, green hydrogen infrastructure, and hydrogen-powered drones.
