Wood chips

Selecting the correct wood chip depends heavily on the end-use. For biomass energy, prioritize calorific value and low moisture content (ideally <25%) to ensure combustion efficiency. For pulp and paper production, focus on species uniformity (e.g., Eucalyptus or Acacia) and strict size distribution to ensure even chemical penetration. For landscaping or animal bedding, ensure the chips are bark-free and non-toxic, with a focus on aesthetic color or absorbency levels.

Buyers must evaluate particle size distribution (typically 5mm to 50mm) to prevent machinery clogging. Ash content is critical for fuel applications, where lower than 1% is preferred. Additionally, check for foreign matter contamination (stones, metal, plastic), which should be less than 0.5%. For international trade, the bulk density (kg/m³) is a vital metric for calculating shipping costs and storage requirements.

Compliance is the most critical barrier in timber-related trade. Ensure suppliers provide FSC (Forest Stewardship Council) or PEFC (Programme for the Endorsement of Forest Certification) to prove sustainable sourcing and avoid illegal logging penalties. For phytosanitary safety, a Phytosanitary Certificate is mandatory to prove the chips are free from pests. Many countries also require Heat Treatment (ISPM 15) or Fumigation Certificates to prevent the cross-border spread of invasive species.

Request a third-party lab analysis (e.g., SGS or Intertek) that specifies the Net Calorific Value (NCV) and Gross Calorific Value (GCV). Since wood chips are often sold by weight, moisture content (MC) significantly impacts value; use a moisture meter during pre-shipment inspection. It is recommended to negotiate pricing based on a 'Bone Dry Metric Ton' (BDMT) basis rather than 'Green Metric Ton' (GMT) to avoid paying for water weight.

The biggest risk is quality degradation during transit, such as fungal growth or spontaneous combustion if moisture and ventilation are not managed. Another risk is regulatory seizure due to incomplete documentation regarding the species' CITES status. To mitigate this, use Made-in-China.com's secured payment services and hire independent inspectors to verify the cargo at the loading port.

Due to the low value-to-volume ratio, freight costs can exceed the product value. CIF (Cost, Insurance, and Freight) is common for new buyers, but experienced importers prefer FOB (Free On Board) to maintain control over shipping lines and schedules. Always clarify the loading rate (tonnes per day) and demurrage terms in the contract to avoid unexpected port charges.

Never transfer full payment upfront. Utilize Letters of Credit (L/C) or Escrow services provided by reputable platforms like Made-in-China.com. Ensure the contract includes a dispute resolution clause and specifies that final payment is contingent upon the issuance of a Clean Report of Findings by an inspection agency at the port of origin.
