HSN Code Details
This product is a refined insulating fluid derived from mineral oils, formulated to provide dielectric strength and thermal stability for electrical equipment. It is processed to meet specific viscosity and purity standards required for high‑voltage applications.
Containers are typically 20‑foot ISO units sealed with tamper‑evident closures; documentation must include a Certificate of Analysis and compliance with the IEC 60296 standard for insulating oils. Temperature control during transit is essential to preserve viscosity characteristics.
