孟加拉采购需求：无机肥料、有机肥料、农药

I'm interested in sourcing magnesium for our upcoming projects. Could you provide detailed specifications, including purity levels, available forms (like powder or granules), and any certifications that your product holds? Additionally, please share your pricing structure, minimum order quantities, and lead times for delivery. It would also be helpful to know about any bulk purchasing options or discounts available. Looking forward to your prompt response!
