As we know, filter plates are consumables for our operation. When we once dealt with #4 filter plates shortage issue and tried to optimize the inventory strategy of #4 filter plates, we realized current vendor has the difficulty on their production flexibility due to the specialty of our current #4 filter plate, in which it resulted in uncompromisable lead-time period (4 Months) and non-negotiable price (US$2.7K/ each). Therefore, there is the thought that it could be an opportunity to shorten the lead-time and lower the #4 filter plate’s cost if we can normalize the plates or get other supplier to offer us the plates.
