I'll assume by product you mean hardware, not software.
Bluetooth, Wi-Fi, ...?
BTLE devices are not required to be MFi certified. See https://mfi.apple.com/MFiWeb/getFAQ.action
Note that while questions surrounding the Core Location framework & iBeacon related API are appropriate for devForums, I'd not expect much help here with your own hardware.
For info on iBeacon licensing, ranging, etc., see https://developer.apple.com/ibeacon/
iBeacon HardwareiBeacon-enabled hardware and accessories must integrate iBeacon technology to ensure a reliable and consistent experience for customers. For information about deploying devices, read Getting Started with iBeacon.

I plan to develop that send iBeacon from Android systems.
But Android's BLE can not set 'advertise-interval' to '100ms'.
So, can not develop iBeacon-enabled-Android systems?
Apple Developer Forums is a community for discussing developer-level issues with Apple’s SDKs and tools. It is not an official Apple support channel, even for developer issues, and it’s definitely not the right place to feedback/get answers about non-apple platforms.
I was not understood.
I will try to contact apple directly.
