2710.12.45.45/Transformer Insulating Oil Type II/China

Transformer Insulating Oil Type II from China

This is a highly refined mineral oil specifically formulated for use in electrical transformers, containing over 70% petroleum oils with less than 50% of any single hydrocarbon. It meets the criteria for light oils under 2710.12 as 90% or more distills at 210°C, and is classified under 2710.12.4545 due to its function as an insulating or transformer oil. The oil provides dielectric insulation and cooling in high-voltage transformers.

Import Tips

• Obtain Certificates of Analysis (COA) confirming volatile matter, distillation specs per ISO 3405, and hydrocarbon composition to verify classification; ensure MSDS includes flash point and purity for DOT compliance; common pitfall is misclassifying as general lubricant oils under 2710.19 if not proven insulating
