Quality Control (QC)

   
ISO 9001:2008 Certified by Bureau Veritas

For more than 28 years or excellence, Sun Siam Co., Ltd. has a strong commitment on the quality of the products. Our lubricants are produced from imported high performance additives (from USA, Germany, UK, Switzerland, and etc.) and only new high quality base oils.

We are strict about the input materials and the specifications of our finish products. Base oils are subjected to test their viscosity and properties before feeded into the storage tankers.

In the manufacturing process, before filling process of finish products, the samples are collected for laboratory test which performed by Sun Siam Co., Ltd. in-house laboratory.
