Import Tips

• Provide CFD simulation data or test reports demonstrating propellant mixing function for classification support

• Material certs for high-temperature alloys (Inconel, etc.) help verify suitability for rocket combustion

• Avoid bulk stainless steel plate classification by including engine integration drawings
