Chapter 44 covers wood and articles of wood, including logs, sawn timber, veneer sheets, plywood, fiberboard, articles of wood, wooden doors and windows, wooden furniture, etc. This chapter does not include furniture mainly classified under Chapter 94, but includes builders' joinery and carpentry of wood. Articles of wood remain classified in this chapter even if they have been surface-coated or preservative-treated, but if combined with materials such as metal, they may be classified under other chapters. Heading 4418 covers builders' joinery and carpentry of wood, mainly including wooden doors, windows, door frames, window frames, stairs, railings, flooring, formwork, etc. However, note that wooden doors and door frames with metal fittings such as locks and hinges are still classified under this heading as long as the metal fittings are not the essential character. If a door frame and door are combined into a complete unit, they are usually classified as a door. Code 441820 is a six-digit subheading: the first two digits 44 represent Chapter 44, wood and articles of wood; digits 3-4, 18, represent heading 4418, builders' joinery and carpentry of wood; digits 5-6, 20, represent the subheading for wooden doors and their frames. Among these, the 5th digit 2 indicates doors and their frames, and the 6th digit 0 is the subheading subdivision. This subheading specifically includes wooden doors, door frames and their fittings, whether or not coated or preservative-treated, provided they retain the essential character of articles of wood. This commodity is classified under 441820 rather than other codes because it is a wooden door and door frame for building use, meeting the description of heading 4418. If a door has a glass viewing panel but the main body is wood, it is still classified under this code; if the door frame is made of metal, it is classified under Chapter 73; if the door is made of plastic, it is classified under Chapter 39. If a door and door frame are combined into a complete unit and metal fittings constitute the essential character, it may be classified under Chapter 94 as furniture, but generally doors for building use are still classified under 4418.

🎯 Classification Logic
The core basis for classification is whether the commodity meets the description of heading 4418, "builders' joinery and carpentry of wood," and specifically whether it is a door or door frame. It must satisfy: 1) the main material is wood; 2) it is used in the construction field; 3) it is not combined with other materials to form a product with the character of another heading. If a door has glass or metal fittings, it is still classified under 441820 as long as the wooden part constitutes the essential character. If the door frame and door are declared separately, the door frame is also classified under 441820. 441810 Wooden windows and window frames: 441810 is for windows and window frames, while 441820 is for doors and door frames. The difference lies in the function of the commodity: windows are used for lighting and ventilation, while doors are used for passage. 441840 Wooden formwork: 441840 is for builders' formwork, used for concrete pouring, not door frames. Door frames are permanent building components, while formwork is temporary. 940340 Wooden furniture doors: 940340 is for wooden doors for furniture, such as cabinet doors, and belongs to furniture parts. Doors for building use are classified under 441820, while furniture doors are classified under 940340. 730830 Iron or steel doors and door frames: 730830 is for iron or steel doors and door frames. If the door frame is made of metal, even if the door is wooden, classification must be based on the essential character. Is the commodity a door or door frame for building use? Is the main material wood? Does it have a metal frame or major metal fittings? Is it used for furniture rather than construction? Has it been coated or preservative-treated?
