Import Tips

• Specify response time (<10ms) and propellant compatibility (hydrazine, etc.) to confirm RCS application

• Space-qualified certifications (NASA/ESA standards) strengthen classification as reaction engine parts

• Prevent classification as generic valves by including thrust chamber integration details
