Allowing imports haphardly is a double edged sword that unfortunately is very sharp on local manufactures and barely cuts on imports 
I'll explain
If say chloride makes batteries here and sells them for 10k this 10k will go into pockets of about 100 people directly 
Person B comes let's call her shiqew and brings batteries and sells them for 8500 this money only benefits her 
Now government needs to protect chloride at all cost to make it slightly harder to just come into the market as a trader of imports for what can be manufactured locally 
For as long as we consume more than we produce out money goes outside and more and more companies will close shop 
Examples 
East African cables amongst others 
Please don't come here with that local companies should match imports on prices bullshit 
It's a scale issue the more batteries we buy from chloride the better his prices would be because of utilization of his production line 
Chloride in this is used a placeholder to reflect local assembly and manufacturing
