Trader countries of forest products have well profit. Commonly, these are developed countries that use the natural forest and tree plantation. One of the principles of trade effective is following; identification the effect of trade index such as price of export and import and also quantity of product, import and export on each others. Therefore, the basic of questions as fallow: how is the effect of some trades variables on each others? Since, econometric methods such as Vector Autoregressive (VAR) and Impulse Response Functions (IRF) were used. VAR results were showed that mostly, the effect of price of export and import on the prices, quantity of import, export and product are significant in world forest products particularly; fiberboard and sawn-wood. IRF results were showed that the shocks effect of quantity of import on the quantity of export and product are divergent in wood based panel and fiberboard and also, the effects were confirmed by VAR. The increased production of fiberboard is showed in production of medium density fiberboard (MDF) Iran. Convergence of variables effects and the lack of significant variables effects on the each others could be because of production and import of forest products is required for resolve local needs.
