Import Tips & Compliance
• Provide pour point and viscosity specs per ASTM standards to validate transformer suitability
• For bulk imports >1000 barrels, ensure accurate barrel volume declarations (158.98L at 15.6°C)
• Avoid common pitfall of incomplete MSDS submission, which delays electrical fluid clearances
