I have produced solid wood flooring, and that customer doesn't need that certification. In addition, according to the policy of China Customs, the export of wood products basically needs commodity inspection. For solid wood flooring, customers generally need fumigation (the fumigation certificate issued by the commodity inspection bureau is used for customs clearance at the destination port), and solid wood composite is generally not needed. Not all wood products need steaming.
I hope it will help the landlord.
