Lab Reports, Test Methods & Downloadable COA / SDS
A Certificate of Analysis (COA) is the document that turns “trust us” into a checkable number. Every batch we grade is tested by an accredited third-party laboratory against published standards, and the result is what fixes the batch’s place on the A / B / C ladder. This page explains the test methods, shows what a COA contains, and is where you download the proof set.
Engineered for barbecue and grilling — not shisha.
Test Methods
Coconut-shell BBQ charcoal is characterised by proximate analysis (moisture, volatile matter, ash, and fixed carbon), its calorific value, and its sulfur content. The primary methods we report against are the ASTM charcoal/coal methods; some labs report the equivalent ISO or coal-industry method, which we note so a COA from any of our labs is comparable.
| Property | Primary method | Equivalent method | What it indicates |
|---|---|---|---|
| Moisture (as received) | ASTM D1762 | ISO 11722 | Water carried in the product — and whether weight is being padded with it |
| Volatile matter | ASTM D1762 | ISO 562 | Degree of carbonisation; high volatiles mean more smoke |
| Ash content | ASTM D1762 | ISO 1171 | Non-combustible residue left after burning — lower is cleaner |
| Fixed carbon | ASTM D1762 (by difference) | — | The fuel fraction — drives heat output and burn time |
| Gross calorific value | ASTM D5865 | ISO 18125 | Energy content per kilogram (bomb calorimeter) |
| Total sulfur | ASTM D4239 | — | Sulfur in the fuel; low sulfur for food-contact grilling |
Our own per-grade results are published only from an accredited COA, with the method cited on every value — never a benchmark presented as our number.
⚠ Pending accredited lab
Our measured proximate, calorific, and sulfur values for each grade are published from the accredited COA once issued. Until then, the grade and ready-stock pages show pending-lab placeholders with the method, not a number.
Test method: ASTM D1762 / D5865 / D4239
What a COA Contains
A complete Certificate of Analysis for a batch lists:
- the lot / batch reference and the date it was tested;
- the proximate analysis — moisture, volatile matter, ash, and fixed carbon — each with its method (ASTM D1762);
- the gross calorific value (ASTM D5865 / ISO 18125);
- the total sulfur (ASTM D4239);
- the shape and size of the briquette tested (hexagonal or pillow);
- the accredited laboratory, its accreditation number, and the signatory.
A certificate is only as trustworthy as its date and its lab, which is why every file in the library below is versioned and dated, and why we never show a fabricated certificate number.

Questions
A COA is an accredited third-party lab report for a specific batch, listing the measured proximate analysis, calorific value, and sulfur — each with its test method — so a buyer can verify the batch meets its grade rather than taking the figure on trust.
Proximate analysis (moisture, volatile matter, ash, fixed carbon) by ASTM D1762, gross calorific value by ASTM D5865 (equivalent to ISO 18125), and total sulfur by ASTM D4239. Some labs report the equivalent ISO or coal-industry method, which we note on the COA.
Accredited third-party laboratories — Sucofindo (KAN LP-024-IDN), SGS Indonesia, Carsurin, Beckjorindo, and Intertek. Using an accredited, independent lab is what makes the COA verifiable rather than a self-declared number.
Yes. The current dated COA, the SDS, and the UN N.4 self-heating test are in the document library above; where a file shows a pending state its current dated version is being finalised and is never shown as a fabricated certificate. Ask over WhatsApp for the latest pack.
