We supply importers and brand owners under their own private label, from ready stock, by full 20' or 40' container, FOB Semarang.
PT Hookah Coals Charcoal Indonesia manufactures coconut shell charcoal briquettes for shisha and hookah, also sold as shisha charcoal and hookah coals. 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 Semarang, Central Java, since 2017, with a capacity of 250 tons per month. We ship to Saudi Arabia, Lebanon, Iraq, Kuwait, Turkey, the USA, Germany, Russia and other markets. 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.
Finished charcoal is held in ready stock in our Semarang warehouse, so there is no production queue for your order. Printing your branded boxes and cartons is the only wait, typically 2–3 weeks.

Every container leaves under the buyer's brand. The process has four steps, and because the charcoal is already in stock, only the printing takes time.
You send box sizes, piece counts, carton format and your artwork or brand guidelines.
We return print-ready dielines for each inner box and master carton for your approval.
We produce a branded sample for sign-off before the full print run.
Printed packaging is filled from ready stock, inspected and loaded into your container.
Minimum print run is 5 t per design: up to 3 designs in a 20' container and 5 in a 40'.
