Best Options for Buying Bath Salts in Bulk for Growing Brands?

I’m exploring suppliers that offer buy bath salts in bulk options for a small but growing bath and body brand, and the Midwest Sea Salt Company keeps coming up in my research. They appear to specialize in mineral-based bath products and support both private label and wholesale production.

What I’m trying to understand is how well they work with brands that are scaling up. Consistency, ingredient quality, and reliable supply are important, especially when moving from small batches to larger orders. Midwest seems to position itself as a long-term manufacturing partner rather than just a basic supplier, which is appealing.

Has anyone here sourced bulk bath salts from them or used their manufacturing services? How was the overall experience in terms of quality, lead times, and support? I’d appreciate hearing any insights before making a decision.

Thanks in advance for any feedback or recommendations.
