Our in-house testing lab provides data to determine whether improvements are needed for new product designs and components prior to mass production. All evaluations are conducted based on our established assessment guidelines.

We dispatch engineers to conduct process verification on the production line, aiming to improve quality and prevent defects before they occur.

After production is completed, INS conducts random sampling inspections based on international standards such as MIL-STD-105E and ANSI/ASQC Z1.4, and determines pass or fail according to the specified criteria.
Full inspections are also available upon request.

We conduct factory audits for the selection of new suppliers or subcontractors, as well as pre-purchase verification. These include comprehensive documentation reviews and on-site inspections, conducted using structured checklists.
In addition, audits of R&D and engineering departments are also available.
We provide detailed investigation reports to assess whether the facility is equipped and organized to perform root cause analysis in the event of a quality issue.

During container loading, our inspector is present on-site to verify the condition of the container for any damage or contamination and to ensure that the products are loaded safely and securely.
A detailed report with photo documentation is provided upon completion.

Leveraging our extensive database, we provide sourcing services for Chinese OEM manufacturers of electrical appliances and component vendors for electronic and electrical parts.
We also offer application support for various safety certifications and standard logo approvals, such as Bluetooth, through authorized laboratories in China.
