TSMC Assists Its Suppliers to Achieve 100% Conflict-free Sourcing

TSMC Assists Its Suppliers to Achieve 100% Conflict-free Sourcing

TSMC supports the "responsible sourcing" practice advocated by the Electronic Industry Citizenship Coalition (EICC) and the Global e-Sustainability Initiative (GeSI), and adopts their jointly developed Conflict-Free Smelter Program (CFSP) to require and help our suppliers to source conflict-free minerals. Meanwhile, we have implemented a series of compliance safeguards in accordance with industry leading practices...

TSMC Collaborates with TSIA to Enhance Occupational Safety and Health of Semiconductor Industry Supply Chain

The thriving development of Taiwan's semiconductor industry is attributed not only to the joint efforts of Taiwan Semiconductor Industry Association (TSIA) members, but also to the strong logistical support of supply chain vendors. Enhancing the occupational safety and health of supply chain employees is a material issue that TSMC is deeply concerned about. As a result, TSMC actively formulates management...

Supply Chain Management Measures

There are over 1,500 suppliers doing business with TSMC. To accelerate their alignment with international standards, we have established our own Supplier Code of Conduct based upon the EICC Code. TSMC set up a project to bring sustainability into daily supply chain management by means of supplier selection, audit, performance measurement, training and the annual supply chain management forum.
Supplier Assessment

All suppliers must be qualified and follow the supplier's code of conduct

  • Process related raw material supplier: obtaining ISO9001 certification (Quality Management Systems Standards) is mandatory
  • Facility suppliers and subcontractors: obtaining OHSAS18001 certification (Occupational Health and Safety Assessment Series) is mandatory
  • Local manufacturer: obtaining a valid factory registration certificate issued by the local government and ISO14001 certification (Environmental Management Standards)
Supplier Audits
  • TSMC has set up an audit team and a tutoring team to trace the progress of deficiency improvements. These teams work with suppliers to improve quality and technology, enhance the process and production yield, elevate ESH performance as well as implement automation for capacity expansion. TSMC also requires suppliers' commitment for waste reduction.
Supplier Training
  • TSMC hosts training and workshop time to time. Through different forms of guidance and communication, the performance of environmental and safety and health is expected to be enhanced and aligned with international norms effectively. The course includes workplace hygiene, employee health, fire prevention and maintenance, carbon emission investigation, climate change, regulatory risk, business ethics and conflict minerals.
Supplier Forum and Awards
  • In addition to conveying the sustainable concept and objectives of TSMC, TSMC also awards the outstanding performance and significant contribution in four areas which are excellent quality, cost effective, ensuring supply and sustainability in the supply chain forum.

Supplier Waste Reduction Programs and Results

TSMC believes that the best waste reduction approach is to reduce its generation at the source and make use of circular economies to manage it as a resource. As such, TSMC encourages local material suppliers to initiate waste reduction programs. For 2016, these suppliers collectively reduced their unit waste output by 18.8% (against the 2014 baseline), translating to 17,000 metric tons in cumulative weight since the program started.
