Karawang, November 2024. The lobby of PT Adharco Jaya Selaras looked like a hall of fame. Trophies and awards filled the shelves, and framed certificates lined the wall. That morning, however, two new documents took center stage. Two men stood side by side, each holding one up with a proud smile. After months of work, Adharco’s E-mark certification was finally complete.
The document in their hands was an E57 certificate. For an automotive parts maker, this is a big deal. It shows that the product meets strict international vehicle safety rules. Behind the scenes, Global Service Agency guided every step of the journey.
Who Took Part in the E-Mark Certification?
First, there was PT Adharco Jaya Selaras, a manufacturer based in Karawang, West Java. The company makes [product type], and it wanted to prove its quality on the global stage. Second, there was [Taiwan lab name], an accredited testing laboratory in Taiwan. Third, there was Global Service Agency (GSA), which managed the entire process and handed over the final certificate.

What Is E-Mark Certification?
The E-mark is an international approval mark for vehicles and automotive parts. It comes from UNECE regulations under the 1958 Agreement. In simple terms, it proves that a product meets agreed rules for safety and environmental protection.
Each E-mark carries a number that shows which country granted it. For example, E1 stands for Germany. Meanwhile, E57 stands for San Marino. Most importantly, all member countries recognize a certificate from any other member. So, one E57 certificate can open doors in many markets at once.
When and Where Did It Happen?
The handover took place in November 2024 at Adharco’s office in Karawang, West Java. Karawang is one of Indonesia’s biggest industrial areas. In fact, many automotive and manufacturing companies run their factories here. However, the testing itself happened far away, at a laboratory in Taiwan.
Why Does E-Mark Certification Matter?
Automotive parts affect the safety of drivers, passengers and everyone else on the road. Therefore, many markets only accept parts that carry the E-mark. Without it, a manufacturer can lose access to export markets and major buyers.
For Adharco, E-mark certification brings three clear benefits. First, it proves that its products meet international standards. Second, it builds trust with carmakers and distributors. Third, it opens new export opportunities beyond Indonesia.
How Did GSA Guide the Process?
Our team handled the process from start to finish. First, we reviewed Adharco’s product and prepared the technical documents. Next, we chose an accredited lab in Taiwan and arranged the product testing. Then, we coordinated with the approval authority to issue the certificate. Finally, we brought the E57 certificate home to Karawang.
E-mark certification also requires strong quality control in mass production. For that reason, we helped Adharco show that every unit meets the same standard as the tested sample. As a result, the approval went through smoothly.
“Many Indonesian manufacturers already make world-class products,” said a member of the Global Service Agency team. “E-mark certification simply gives them the proof they need to compete globally.”
