Import Tips & Compliance
• 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
