In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Diamond 3.
Why leak prevention matters on the Diamond 3
Consistent filling torque and proper sealing rings remove most transit leaks.
Documentation is not paperwork for its own sake; on leak prevention it is the difference between a clean clearance and a delayed one.
