UL Listed Terminals & Certified Quality
Marrow Lin supplies UL listed terminals certified to ISO 9001:2015, RoHS, REACH and full JIS / DIN standards — backed by consistent in-house quality control.
UL Listed Terminals, Built to Standard
Every Marrow Lin terminal, lug and ferrule is manufactured to internationally recognised standards. From raw copper to finished crimp, our process is controlled to deliver the consistency that professional installers and OEM buyers depend on.
Quality is not a final check — it is built into each stage, from material selection and plating through to dimensional inspection and electrical testing.
- UL-recognised components with traceable file numbers
- ISO 9001:2015 quality management system
- RoHS & REACH compliant materials

What UL Listed Terminals Mean for You
When a product is described as UL listed, it has been evaluated by Underwriters Laboratories against recognised safety standards. For buyers sourcing into North America, UL listed terminals are often a requirement rather than a preference — specifiers, inspectors and insurers expect them. Marrow Lin holds three UL files (E488241, E182951 and E255748), so you can specify our terminals with confidence and trace the certification back to its source.
Certification, however, is only meaningful if quality is consistent. That is why every Marrow Lin product is made within an ISO 9001:2015 quality management system, with controls at each stage from incoming material to final packing. The aim is simple: the terminal you receive on your hundredth order performs exactly like the one on your first.
The standards we manufacture to
Different markets rely on different standards, so we maintain ranges built to both JIS (Japanese Industrial Standards) and DIN (German standards). Our cable lugs follow DIN 46234 and DIN 46235, and our bootlace ferrules follow DIN 46228 — the references your European customers will recognise. For chemical compliance, our materials meet RoHS and REACH requirements.
Documentation for your project
We know that winning a tender or clearing an import often depends on paperwork. On request we can supply UL certificates, our ISO 9001 certificate, RoHS / REACH declarations of conformity and product datasheets. Having this documentation ready helps your procurement and quality teams move faster.
Quality control in practice
Behind the certificates is day-to-day discipline: verifying incoming copper and insulation, controlling stamping and plating parameters, checking dimensions against tolerance, and sampling crimp pull-force and electrical performance before products are counted, labelled and packed for export.
Frequently Asked Questions
What does “UL listed” actually mean?
It means the product has been tested and certified by Underwriters Laboratories against applicable safety standards. UL listed terminals are widely expected for installations in North America.
Which UL file numbers does Marrow Lin hold?
We hold three UL files: E488241, E182951 and E255748. These can be referenced for verification and supplied with your documentation.
Are your products RoHS and REACH compliant?
Yes. Our materials meet both RoHS (restriction of hazardous substances) and REACH (EU chemical) requirements, making them suitable for electronics and EU-bound products.
Do you provide certificates and datasheets?
We do. On request we can supply UL certificates, our ISO 9001:2015 certificate, RoHS / REACH declarations and product datasheets for your tender or import paperwork.
Do you manufacture to DIN and JIS standards?
Yes. We produce ranges to both DIN (including DIN 46234/46235 lugs and DIN 46228 ferrules) and JIS standards to suit different markets.
Is ISO 9001:2015 the current standard?
Yes. ISO 9001:2015 is the current revision of the international quality management standard, and our quality system is certified to it.
What is the difference between DIN 46234 and DIN 46235?
Both are German standards for copper cable lugs; they cover different lug constructions and dimensions. Our guide explains which to choose for your application.
Are your terminals lead-free?
Our materials are RoHS compliant, which restricts lead and other hazardous substances, making them suitable for electronics and EU-bound products.
Can you provide a declaration of conformity?
Yes. On request we can supply RoHS / REACH declarations of conformity along with our UL and ISO 9001 certificates.
Do your certifications cover all product lines?
Our UL files and ISO 9001 system cover the applicable ranges. If you need confirmation for a specific item, just ask and we will clarify.
