This case study presents Yihang Carbon’s stable supply of 40 tons of premium wood-based powdered activated carbon to a long-term customer in Pakistan, dedicated to sugar cane decolorization and sucrose refining. With consistent product performance, trustworthy cooperation, and thoughtful service, we have maintained a close partnership for more than 10 years, becoming a reliable raw material supplier for the client’s sugar manufacturing business.

The client is a respected sugar mill owner in Pakistan, nearly 80 years old, who has been cooperating with Yihang Carbon steadily for over a decade. This year, he visited our factory for the first time, and our company leaders attached great importance to this visit and warmly received our long-term partner.
The client owns his own sugar manufacturing plant, which requires large quantities of high-quality activated carbon annually for sugar cane juice extraction, purification, and decolorization during the sugarcane harvest season. Upon receiving his order, our team quickly confirmed all technical requirements and production arrangements.

Since the client uses the products for self-consumption, there was no special requirement for packaging. Our team arranged standard safe packaging to ensure the products remained dry and intact during long-distance transportation. The transaction was conducted under LC payment terms, with smooth and efficient coordination throughout the whole process.

Our logistics team formulated a complete shipping plan to ensure timely and safe delivery of the 40 tons of powdered activated carbon to Pakistan. We maintained close communication with the client and provided timely updates on production and logistics progress.
In the end, the goods were delivered on schedule as agreed. The client was highly satisfied with the product quality, decolorization performance, and our professional service.

In this long-term cooperation, the client’s core requirements focus on stable decolorization efficiency, reliable product consistency, and on-time supply during the sugar production season.
