Methanol is the main raw material of formaldehyde. At present, the production of one tonne of formaldehyde needs about 0.43 tonne of refining methanol. The production cost of raw materials accounts for around 90% of the total production cost of formaldehyde in China. The price of methanol decides the price of formaldehyde.

The price of formaldehyde can be calculated by the following formula:  

The price of formaldehyde=0.43*the price of methanol/0.9+profit (about USD22~55/t)
