WOOD CHIPS SUPPLY LTDA currently supply of different types of wood chips in general from EU, USA, Brazil, Columbia and Chile of Pine (SYP/Elliotte / Radiata /Taeda ) Chips and Eucalyptus (Grandis/ Globilus) Chips and Wood Logs. Also, we ready to supply of Acacia, Beech, Eucalyptus and Pine Wood Chips up to 40.000 BDMT per vessel by very good low prices.
The wood chips are recognized as one of the best wood chips for manufacturing of MDF, clipboards, paper, thermo-mechanical pulp and kraft pulp.
Clean, mill, or paper-grade woodchips are those meeting paper-making specifications that are produced as a by-product of lumber production by sawmills or as a primary product produced by chip mills that debark and chip roundwood and screen the chips.
Grade A Clean, Mill, or Paper-Grade Chips Sources: Sawmills and Chip Mills Clean woodchips are the highest-quality woodchip due to their low ash content, consistent moisture content, and uniform shape and size. High-quality logs are brought to sawmills to be made into lumber. The business of sawing rounds logs into square boards generates wastes such as slabs and offcuts, which can be chipped at the sawmill. These logs are de-barked prior to chipping and the resulting chips are screened to remove fines and over-sized pieces. The result is a clean chip with consistent shape and size.
The chips has in general the mentioned below species:
100 % Chips Fresh cut and healthy trees

- 19mm – 5mm: 35.0% max.
- 5mm – 3mm: 3.0% max
- Under 3mm: 2.0% max.
- Bark shall and rot shall not exceed 1.5%.
Chips shall be free from char and other foreign materials such sand, stones, plastics and coal, etc.
The moisture content of the wood chips shall not exceed 50% Fumigation treatment
The raw materials of woodchips can be pulpwood, fresh logs wood, and residual wood from agriculture, landscaping, logging, and sawmills.
Woodchips can also be produced from remaining forestry materials including tree crowns, branches, unsaleable materials or undersized trees.
Forestry operations provide the raw materials needed for woodchip production. Almost any tree can be converted into woodchips, however, the type and quality of the wood used to produce woodchips depends largely on the market. Softwood species, for instance, tend to be more versatile for use as woodchips than hardwood species because they are less dense and faster growing.
A wood chipper is a machine used for cutting wood into smaller pieces (chips). There are several types of wood chippers, each having a different use depending on the type of processing the woodchips will undergo.
Pulp and paper industry
Woodchips used for chemical pulp must be relatively uniform in size and free of bark. The optimum size varies with the wood species It is important to avoid damage to the wood fibres as this is important for the pulp properties. For roundwood it is most common to use disk chippers. A typical size of the disk is 2.0 – 3.5 m in diameter, 10 – 25 cm in thickness and weight is up to 30 tons. The disk is fitted with 4 to 16 knives and driven with motors of ½ - 2 MW. Drum chippers are normally used for wood residuals from saw mills or other wood industry.
Methods of conveyance: There are four potential methods to move woodchips: pneumatic, conveyor belt, hopper with direct chute, and batch system (manual conveyance)
We have joint company cooperation with our one of main Producers in Brazil producing of Pine (Elliott / Taeda ) Chips and Eucalyptus (Grandis/ Globulus) Chips.
