坦桑尼亚采购需求：一体式太阳能路灯

Salve, I'm looking for pricing details regarding a specific product, particularly for an order of 120,000 units to be delivered in Dar es Salaam. Could you provide me with your unit price for this quantity, along with any available information on lead times and shipping options? I'd also appreciate knowing if there are any discounts or special terms for bulk purchases. Additionally, please share your payment terms and any relevant certifications or quality assurances that your products hold. Understanding these details will greatly assist in our decision-making process as we consider moving forward with a potential order. Looking forward to your prompt response!
