1.Testing / Certification from international labs (TUV / Intertek / SGS / Dekra / ETL / UL, etc.)
GST's lab is accredited by TUV / Intertek / SGS / Dekra / ETL / UL, which means GST's lab is allowed to take the some testing in GST's lab (safety, battery safety, some EMC etc) and TUV, Intertek /ETL etc. will review the data and testing procedure, then issue the report according if all OK. This will help client / supplier can have the quick feedback from testing, faster lead time, and easier communication than working with those labs directly. Moreover, those labs have been set up a team (assistant, engineer) to service GST.

2.CNAS lab resource
A testing lab in China is impossible to cover all product categories and professional in all areas. Consider GST's clients are importers / retailers which would cover many different product categories. Hence, GST's has built a widely network for all different Chinese lab for different product categories, which means GST's can provide service for importers with many product categories.

3.Testing cost
By considering all GST's current business with all labs, GST's has gained a special price with those labs, so even adding GST's service value and cost, clients still are able to get a very competitor offer rather than work with those labs directly.
