I think you should provide them the list price as I gave you the price list and let them wait for the lead time by sea freight because we have to combine other products to meet the MOQ.
One more thing, please ask them about possibility to repeat order because we might order 4 x 190kg of TCS6500 and other such as Aquagel 45 …etc. that means we will keep the stock (not pressure you to sell but try to more promote and help each other expand business)
