The briquettes are carbonized coconut shell bound with tapioca starch. We do not make wood charcoal, BBQ charcoal, quick-light coals or activated carbon.
We have operated a factory in Magelang, Central Java, since 2017, with a capacity of 250 tons per month.

We sell wholesale only, with a minimum order of one full 20' or 40' container, and every order is packed under the buyer's own private label.

home-export-deskCoconut shell charcoal moves by sea as UN 1361 CARBON, Class 4.2, a self-heating substance. Since 1 January 2026, IMDG Code Amendment 42-24 makes dangerous goods declaration of charcoal mandatory for sea freight. Special Provision 978 sets the carriage conditions — weathering before packing, packing temperature and container headspace — and is not an exemption.
