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
