Actually, our engineering advises you may proceed dismount during this window period before we have 1st batch of new cylinder under new inspection process. And our quality team suggests have all cylinder returns that we could ensure the serial nos. be correspond per body serial nos., also the dismount and assembly will take same time, hope you are with me that is not the issue of insistence on first in or out issue. We fully understand the situation per your customers status which we kept declaring the standard never changes for the thread also did not build any control plan until last Nov. but we are always mutual supports and put any issue in prioritized as I explained. Refer to the logistic that we have agreed to return all with Sea but if we have other option proposed as cylinder swapping process that we could consider to have old caps via Sea and new batch arrange via Air freight for your future assembly in order to saving the time. Thus, I would like to have my shipping colleagues into this mail assume you’re familiar with Sally and Wendy for further catch up sync in same page.
