Import Tips
• Submit pressure ratings and material certs (e.g
• API 8C) proving suitability for high-pressure oil/gas rotary drilling
• Declare as complete rotary assembly if integrated; separate parts risk different classification
• Avoid pitfall of bulk packaging misread as parts; use retail-ready crating for machinery status
