NusaCoal, the official export brand of PT Berlian Hitam Group, is a verified direct manufacturer and exporter of premium charcoal products. Unlike standard trading companies, we specialize exclusively in producing fully carbonized raw coconut shell charcoal and high-grade natural hardwood charcoal directly from the source.
Under the leadership of our President Director, Hendrik, our operations in Probolinggo, East Java, are driven by a strict commitment to transparency, innovation, and uncompromising quality standards. By operating our own traditional dome kilns and a dedicated warehousing facility, we maintain full control over the production process. Our strategic location provides direct access to the major international Port of Tanjung Perak in Surabaya, ensuring smooth FOB and CIF logistics, highly competitive shipping costs, and timely container delivery for our global partners.
At PT Berlian Hitam Group, quality begins at the source. We carefully select only legally harvested Indonesian hardwoods and fully mature coconut shells, ensuring every batch meets rigorous international specifications for high fixed carbon, low ash content, and exceptional burning performance. Through our meticulous manual grading, mechanical screening, and strict moisture control, we guarantee consistency and reliability in every single shipment.
Beyond supplying bulk raw materials to the global activated carbon and briquette industries, we proudly serve the international retail market with comprehensive OEM and custom packaging services. From heavy-duty master boxes for stick charcoal to full-printing custom retail bags, we tailor our export solutions to fit your unique brand requirements. Our vision is not only to deliver world-class products but to establish long-term, direct factory partnerships built on professional trust and mutual commercial growth.
