Chongqing New Prosper Industry and Trade Co., Ltd (former Kailian Yongrun) was founded in 2002 in Chongqing, China. The company produces and supplies various kinds of petroleum testing equipment and paper food trays.

In 2015, most of our petroleum testing equipment obtained CE certification. Through our implementation of the CE standard, we follow the most strict quality control regulations to manufacture the equipment.

At the end of 2019, our company formed a joint venture with Nanjing YH Paper Products Co., Ltd. and signed a strategic cooperation agreement to begin the production and sales of paper tableware. Our company can provide various types of paper food trays and paper boxes, and can customize them according to customers' requirements. We have a professional team responsible for paper tableware, ensuring good quality, competitive prices, long-term stable supply, and timely delivery.

On March 31, 2022, in order to expand business scale and adapt to the demand of changing market and development strategy, our company renamed New Prosper from Kailian Yongrun and make some adjustments to the business structure. The manufacturing of transformer oil testing equipment was transferred to our partner company in Chongqing, and other businesses were remained at New Prosper.

Cost-effective is sure. Sense of quality is essential. Delivery time is holy. There might be a moment that we lose an order, but there will never be a moment that we will lose our trust, our promise, which keep us going on. And there will never be a moment that we will stop thinking with our customers. We work with people with passion. We work with suppliers with trust. We work with customers with relation.

We will continue listening attentively to our customers and innovating products and services to meet customers' demands. We want to fulfill needs and requirements of our customers in a best possible way to become a preferred supplier. We look forward to being your long term trusted partner. Your contentment is our pursuit.
