孟加拉采购需求：液体靛蓝，液体还原蓝 1，靛蓝，还原染料

I'm interested in getting quotes for two specific products. First, could you please provide the pricing details for indigo blue liquid with a concentration ranging between 30% and 40%? It would be great if you could include any minimum order quantities or bulk purchase options available. Additionally, I would like to inquire about the cost of Sulphur Black. If possible, please share any relevant details regarding shipment and delivery timelines as well. Looking forward to your prompt response so we can discuss potential orders! Thank you.
