Zink,
What I have to say will not help you with the current situation you find yourself in, but I did read that by selecting ingredients (when possible) that are multi-functional or flexible (and therefore used in more than one of your products) you can gain some business advantages. For the small business, they can buy in larger quantities because it will be flowing out the door faster in multiple products. Or adapt to a larger MOQ without as much hardship.
Of course there are often ingredients that are unique to a formula and if that supplier ups their MOQ this isn’t a help. But for those who are not locked into a formula yet, I wanted to mention this tactic. One could for instance find one emulsifier that worked for multiple products instead of using a unique one for each.
Perhaps you can negotiate a grace period with your supplier? Or an exception if you do enough other business with them on other supplies? Offer a slightly higher per-unit price for a lower quantity if they are incurring labor costs to repackage the ingredient in smaller batches?
Or launch a new product which also uses the ingredient, thereby increasing your needed demand such that 5X MOQ is viable for you?
Best luck,
Margeaux
