Pine Wood Siding Boards from Japan

Pine wood siding boards are coniferous wood panels continuously shaped with tongue-and-groove edges for interlocking installation on exterior walls. They are planed and sanded for smooth finish, classified under HTS 4409.10.10 as coniferous wood siding. This shaping along edges distinguishes them from simple sawn lumber.
