Key Factors Affecting Price

Concentration & Form: Liquid (50-60%) is the most economical for bulk industrial use. Solid powder (90-99%) costs roughly 2-3x more per ton than the 50% liquid, but you are paying for higher active content and lower shipping weight.

Order Volume: Bulk orders (1 ton+) receive significantly lower prices. For example, one supplier lists 1 ton at ¥7,500, dropping to ¥7,000 for 5 tons.
