API Q1 is the critical strict quality management system for suppliers in the petroleum and natural gas industry.

JST Seals firstly got the API Q1 certification in early 2018. Every year API would conduct audit to JST, this year the audit time is from October 23 to 28, 2023, and we successfully passed the renewal audit.

Obtaining API Q1 quality certification is an important milestone in the development of JST. Through participating in the API Q1 quality certification and continuous communication with API, we have gained advanced management concepts from API, allowing us to continuously optimize the product quality control process and improve product quality. While allowing our business to cover more than 35 countries and regions, and continue to provide customers with better services.
