In this chapter, the expression 'densified wood' means wood which has been subjected to chemical or physical treatment (being, in the case of layers bonded together, treatment in excess of that needed to ensure a good bond), and which has thereby acquired increased density or hardness together with improved mechanical strength or resistance to chemical or electrical agencies. 3. In headings 4414 to 4421, articles of particle board or similar board, of fibreboard, of laminated wood or of densified wood are to be classified as articles of the corresponding kind of wood. 4. Products of heading 4410, 4411 or 4412 may be worked to form the profiles described in respect of the wood of heading 4409, curved, corrugated, perforated, cut or formed to shapes other than square or rectangular or submitted to any other operation provided it does not give them the character of articles of other headings.

Section IX has no Section Notes. Classification rules are governed by the Chapter Notes of Chapters 44 (Wood), 45 (Cork) and 46 (Manufactures of straw, esparto and other plaiting materials; basketware and wickerwork). Key rules include: Chapter 44 contains extensive exclusion lists directing products to other chapters (e.g., furniture to Chapter 94, instruments to Section XVIII), and defines the scope of 'wood' to include bamboo and other materials of a woody nature. Chapter 45 distinguishes between natural cork and agglomerated cork and their respective articles.
