We exclusively process mature, high-density coconut shells. Our controlled carbonization ensures zero unburned materials and maximum fixed carbon yields.
With fixed carbon exceeding 75% and minimal ash content, our raw shells are the perfect foundation for high-end shisha briquettes and activated carbon processing.
Partner with PT Berlian Hitam Nusantara. We provide secure warehouse stuffing and seamless maritime logistics, delivering up to 25 tons per 40ft HC container worldwide.
Our coconut shell carbonization process is strictly monitored to ensure perfect results, yielding high heat, a long burn time, and extremely low moisture and ash content.

Raw materials dictate the quality of your final briquettes. Our strict grading and screening processes remove coconut fibers, dirt, stones, and unburned shells. You receive pure, 100% carbonized shells ready for immediate crushing and mixing.

Equipped with a massive warehouse in Probolinggo, we seamlessly manage bulk stockpiling, sun-drying, and direct container stuffing. We are fully capable of supplying consistent multi-container shipments year-round.

Our factory is ready to supply coconut shell charcoal on a large scale, without intermediaries, brokers, or middlemen.

(Frequently Asked Questions)
We are a verified direct manufacturer operating our own carbonization facility in East Java, Indonesia. We focus exclusively on producing high-grade raw carbonized materials. By dealing directly with PT Berlian Hitam Group, you eliminate broker markups and secure a direct line to the factory for consistent, long-term supply.
Our raw coconut shell charcoal is carbonized to achieve a strictly high Fixed Carbon level of 70% to 80%. We achieve this by exclusively selecting mature, high-density coconut shells and controlling the temperature inside our kilns. This high carbon spec guarantees superior heat retention and extended burning time for the end products.
Managing residue is our top priority. We guarantee a very low ash content (under 3%) with a clean, light-colored ash characteristic. Before packaging, our raw charcoal undergoes a rigorous screening and manual sorting process to eliminate unwanted residues such as sand, stones, dirt, and unburned coconut fibers (coir).
Absolutely. Our raw coconut shell charcoal is the ultimate foundation for premium briquette manufacturing. Because of its high fixed carbon and zero chemical additives, it yields a high-density powder when crushed. This allows briquette factories to produce premium shisha and BBQ briquettes that are odorless, smokeless, and resistant to cracking.
We guarantee 100% fully carbonized material. Unburned or “brown” shells ruin the quality of shisha briquettes by producing excessive smoke and off-flavors. Our grading team visually inspects every batch post-carbonization to manually remove any undercooked shells, ensuring you receive only uniform, pure black carbon.
We maintain a strict moisture content of under 12%. After the carbonization process, our charcoal is thoroughly sun-dried on expansive concrete floors. This bone-dry specification prevents mold growth during long ocean transits and ensures the material is immediately ready for crushing and mixing at your briquette plant.
We specialize exclusively in raw coconut shell charcoal. We do not manufacture molded shisha or BBQ briquettes. This means we do not compete with our buyers. We are a dedicated raw material supply partner, ensuring that our highest-grade carbon goes directly into your production lines.
Yes. Equipped with a massive warehousing facility in Probolinggo and a vast network of local raw shell collectors, we maintain continuous stockpiling and carbonization cycles. We are fully capable of supplying consistent, multi-container shipments year-round to fulfill your long-term factory contracts.
To maximize cost-efficiency for bulk raw materials, we pack our charcoal in highly durable 20kg to 30kg woven polypropylene (PP) bags. We meticulously stuff these bags (floor-loaded) into containers to maximize space, securely fitting approximately 24 to 25 metric tons into a standard 40ft High Cube container.
We highly encourage factory visits and transparent sampling. International buyers are always welcome to visit our facility in East Java to inspect our stockpiles, witness the screening process, and verify our quality control firsthand. We can also arrange for sample shipments via DHL/FedEx so your lab can test our carbon and residue specifications prior to ordering.
