Import Tips
• Include API specifications (e.g
• API 13A) certification to prove drilling-grade purity and avoid reclassification
• Ship in bulk super-sacks rather than retail bags to maintain raw material status and lower scrutiny
• Watch for moisture content declarations; excessive drying could imply calcining, potentially affecting duty but not heading
