Understanding Wood Pellet Specifications

Looking for reliable information about wood pellet specifications and COA requirements?

A well-defined fuel specification is essential for industrial biomass procurement. It helps buyers compare suppliers, evaluate equipment compatibility, and establish measurable quality acceptance criteria.

IEC | Indonesia Export Center facilitates enquiries for Indonesian wood pellets and encourages buyers to establish technical requirements before requesting commercial offers.

Reference Specification Table

The following figures are supplied laboratory sample references.

Parameter	Reference Value	Verification Requirement
Product	Biomass Wood Pellet	Product identification
Origin	Indonesia	Origin records
Physical Form	Solid Pellet	Visual inspection
Moisture	7.28–9.1%	Current lot test
Ash	1.3–1.88%	Confirm test basis
Gross Calorific Value	4,300–4,402 kcal/kg	Confirm method and basis
Net Calorific Value	3,971–4,066 kcal/kg	Confirm method and basis
Total Sulfur	0.02–0.10%	Current lot test

These values are not guaranteed commercial specifications.

Moisture, Ash and Net Calorific Value

Moisture

Moisture influences energy delivered per kilogram, storage behavior, and pellet integrity.

Ash

Ash represents the inorganic residue remaining after combustion under defined testing conditions.

Net Calorific Value

NCV is important when evaluating the usable energy content of biomass fuel.

Buyers should always compare results using consistent units and reporting bases.

Durability, Fines and Bulk Density

Additional parameters frequently requested by industrial buyers include:

Mechanical durability
Fines content
Bulk density
Pellet diameter
Pellet length
Chlorine
Nitrogen
Ash melting behavior

These values have not been established in the supplied reference and should not be invented.

Sampling Methods

A reliable testing programme should define the lot, sampling locations, number of increments, sample preparation, and handling procedures.

Representative sampling is essential because fuel quality may vary within a shipment.

Third-Party Laboratory Testing

Buyers may require testing by an independent laboratory with suitable competence and relevant accreditation.

The COA should identify the laboratory, sample, method, result, units, and date.

Example COA Fields

Frequently Asked Questions

Is a sample COA sufficient for a commercial shipment?

No. The report must be relevant to the accepted lot and testing arrangement.

Can different laboratories produce different results?

Results can vary with methods, samples, and reporting bases.

Does a COA prove sustainability certification?

No. Those are separate forms of evidence.

Can buyers require third-party testing?

Yes, subject to agreement with the supplier.
