Masan High-Tech Materials is a Vietnamese high-tech manufacturing company specializing in Tungsten chemical intermediates. By converting strategic Tungsten resources into high-purity products such as Ammonium Paratungstate (APT), Blue Tungsten Oxide (BTO), Yellow Tungsten Oxide (YTO), Masan moves beyond the role of a raw materials supplier. Instead, the company positions itself as a global pioneer delivering advanced materials for critical industries worldwide.
To expand in the European chemicals and materials markets, Masan must ensure full compliance with EU chemical legislation, particularly the demanding requirements of the REACH Regulation (EC) No 1907/2006.
Exporting chemical substances into Europe places significant regulatory obligations on non-EU producers such as Masan High-Tech Materials. The key is finding a qualified and trusted partner to:
serve as a REACH EU Only Representative under Article 8 of REACH
provide strategic guidance and plan on testing arrangement & management, data evaluation, and submission
carry out full registrations for required substances
manage obligations such as tonnage updates, new uses not yet accounted for in the chemical safety assessment, and other data revisions
ensure effective communication with ECHA, local authorities and third parties


Chementors was selected as Masan High-Tech Materials’ compliance partner due to its proven track record in representing non-EU companies under REACH. By acting as the REACH Only Representative, Chementors took on the legal duties required by the EU REACH regulation, ensuring that Masan’s substance could enter the European market without regulatory obstacles.
In addition, Chementors prepared and submitted the necessary REACH registration dossiers for Masan’s substance and made sure that they met the European Chemicals Agency’s (ECHA) strict standards for accuracy, completeness, and technical quality. Chementors experts took care of the full process, handled all aspects required for registration from test planning & management with labs, data assessment, to dossier compilation & submission. This single-contact-point service is to help Masan High-Tech Materials focus resources on business matters with peace of mind while leaving REACH matters on Chementors. Beyond initial registration, Chementors continues to manage updates, including tonnage changes, new identified uses, and notifications from ECHA and the Consortium to make sure that Masan remains fully compliant as the regulation develops. Chementors’ approach is to provide Masan with a reliable long-term partnership in navigating the European regulatory landscape.
The collaboration between Masan High-Tech Materials and Chementors has ensured safe and compliant access to the European market for Masan’s high-value Tungsten chemicals. With Chementors managing the complex regulatory framework, Masan can focus on its core strengths: delivering advanced materials, maintaining production excellence, and expanding into new markets.
This partnership has also given Masan High-Tech Materials confidence that its regulatory obligations are handled proactively and professionally, minimizing risks and enabling smooth business operations in Europe. With Chementors’ continuous support, Masan is well prepared to adapt to future changes in EU chemical legislation while strengthening its market presence.
“Chementors’ ability to navigate the complexities of REACH has been instrumental in our EU strategy. Their professional, proactive service has allowed us to push forward with confidence.”
Fedor Mironenko, Director of Sales & Marketing at Masan High-Tech Materials.
