In response to global climate change, countries worldwide are actively implementing carbon reduction policies. Within the aviation sector, the adoption of Sustainable Aviation Fuel (SAF) has become a key strategy in advancing low-carbon transportation. To align with national aviation policies and meet the growing demand for SAF, the Bureau of Standards, Metrology and Inspection (BSMI) has established national standards for SAF and requires that SAF be subject to mandatory inspection. These measures ensures compliance with quality specifications and contribute to the aviation industry's efforts to achieve net-zero carbon emissions.

According to the BSMI, the Executive Yuan has designated SAF as a key initiative under Taiwan's national carbon reduction policies. In alignment with the policies implementation timeline, BSMI has adopted relevant international standards-ASTM D7566 and ASTM D1655-as the reference for establishing and revising the national standards CNS 16221 "Aviation Turbine Fuel Containing Synthesized Hydrocarbons" and CNS 2558 "Aviation Turbine Fuel." These standards define the quality requirements-such as total sulfur content, distillation characteristics, copper strip corrosion, and thermal stability-as well as the corresponding test methods for SAF produced through various processes, serving as regulatory guidance for the domestic aviation fuel manufacturing industry.

BSMI further stated that SAF is primarily produced from non-petroleum-based feedstocks, such as used waste cooking oil. Compared to conventional petroleum-derived aviation fuels, SAF offers significant carbon reduction benefits. The Ministry of Transportation and Communications has set a target for SAF to account for 5% of total aviation fuel consumption by 2030. In addition to advancing carbon reduction goals, ensuring fuel quality is critical. To this end, BSMI has included SAF within the scope of mandatory inspection. All SAF products-whether imported or domestically produced-must comply with national standards CNS 16221 or CNS 2558. This measure ensures that all SAF supplied within the aviation fuel supply chain meets national regulatory requirements.

The relevant CNS national standards are available through the BSMI "CNS Online Service System" (website: http://www.cnsonline.com.tw).
Information on SAF-related inspection requirements, following its inclusion in the list of commodities subject to mandatory inspection, can be found on the BSMI website (http://www.bsmi.gov.tw) under  "Focus News" > "Business Announcements."
