Import Tips & Compliance
• ASTM calibration certificates mandatory for petroleum industry import compliance and quality assurance
• Declare temperature range (e.g
• 60°F API) precisely to match correct HTS subheading
• Hydrocarbon-resistant materials must be documented to prevent reclassification as general labware
