Import Tips

Include propellant compatibility test reports and pressure ratings in import documentation to substantiate reaction engine use

Check for dual-use restrictions under Wassenaar Arrangement; may require end-user certificates

Label clearly as 'not for turbojet engines' to prevent reclassification during customs review
