89.6% of parts comply with the "ASUS Halogen-Free Regulation"


Mineral Oil

No mineral oil in packaging printing material

Safer Chemicals

The ASUS Hazardous Substances Free (Hazardous Substances Free, HSF) standard has aligned with RoHS (Restriction of Hazardous Substances Directive) since 2002, and it also proactively takes the stringent regulations into consideration to include substances such as beryllium, antimony and red phosphorus. After several revisions, the standard goes far beyond the international regulations and also covers IEC 624741 Material Declaration Standard.

ASUS also cares about whether the materials or auxiliaries used in the manufacturing process might cause potential danger to the production line workers and the environment. ASUS controls the use of benzene and n-hexane in the cleaning and decontamination solutions in the manufacturing process. We has gradually introduced low-VOCs (Volatile Organic Compounds) raw materials such as paint and ink since 2020 and continues to ban all substances in the U.S. Toxic Substance Control Act (TSCA) for the purpose of reducing the factors in manufacturing processes that are likely to affect the human body or indirectly cause environmental hazards.

We have adopted big data management since 2021 to predict trends and assess the risks of substances, components, and materials and improve audit quality and management efficiency.


It has been confirmed internationally that halogen flame retardants will produce extremely toxic dioxin, which is harmful to the environment and human health, if improperly recycled and processed, and the parts containing halogen.

Since 2010, ASUS has adopted a halogen-free policy, and in 2022, 89.6% of the products shipped in compliance with the "ASUS Halogen-Free Regulation". And we continue to advance toward higher goals.

  • Banned the use of chlorine in the bleaching process for paper packaging since 2018.
  • Transitioned to halogen-free hard drives and batteries since 2019.
  • Phased out PVC in the Type-C charging cables for the next-generation mobile communication products since 2020.
  • Transitioned to halogen-free PCBs since 2021.The use of halogen flame retardants will be banned for more components and products in the future.

Management of Packaging Materials

With regard to the packaging materials that come into direct contact with consumers, we require them to meet the EU Directive 94/62/EC on packaging and packaging waste (PPWD).

ASUS actively manages current and future international standards for hazardous substances and reduces the environmental hazardous factors that come in direct contact with humans .

  • Gradually introduced low-VOCs (Volatile Organic Compounds) raw materials in paint and ink since 2020.
  • Suppliers are required not to use mineral oil as printing raw materials, further controled the use of plasticizers (Phthalates), and banned to PVC materials since 2021.
  • Phase-out of the use of PAHs (Polycyclic Aromatic Hydrocarbons) since 2023.
