Chapter 44 covers wood and articles of wood, charcoal, including logs, sawn timber, veneer sheets, plywood, fiberboard, articles of wood, wooden furniture, etc. However, certain specific wood products are excluded, such as wood pulp (Chapter 47), wooden furniture (Chapter 94), etc. Goods in this chapter are mainly classified by degree of processing, wood species, use, etc., covering a broad range from raw materials to semi-finished and finished products. Heading 4418 covers builders' joinery and carpentry of wood, including wooden concrete formwork, wooden shingles, wooden windows, doors and their frames, posts, beams, etc. Specifically includes: wooden concrete formwork (4418.40), wooden shingles (4418.50), wooden windows, doors and their frames (4418.10, 4418.20), wooden posts and beams (4418.71, 4418.81), etc. Goods under this heading are mainly used in the construction field, having undergone a certain degree of processing but not constituting finished products listed under other headings. Code 441840 is a six-digit subheading. The first 2 digits "44" represent Chapter 44: Wood and articles of wood; charcoal. Digits 3-4 "18" represent heading 4418: Builders' joinery and carpentry of wood (including wooden concrete formwork, wooden shingles, wooden windows, doors and their frames, wooden posts and beams, etc.). Digits 5-6 "40" represent subheading 4418.40: Wooden concrete formwork. Therefore, 441840 specifically refers to wooden concrete formwork, i.e., wooden formwork used for concrete pouring and molding, usually made of wooden boards, plywood, or wooden strips, etc., possibly coated or waterproofed. Wooden concrete formwork is classified under 441840 because it is a builders' joinery and carpentry article of wood specifically used for concrete construction, conforming to the description of heading 4418 "Builders' joinery and carpentry of wood". Adjacent codes such as 4418.10 (wooden windows) or 4418.20 (wooden doors) have different uses; 4418.50 (wooden shingles) are roofing materials; 4418.71/81 (wooden posts and beams) are structural components. 441840 specifically refers to concrete formwork, hence classified under this code.

Product Name: The Chinese and foreign language names of the declared commodity, which should accurately reflect the product attributes, such as "wooden concrete formwork" or "wooden formwork for construction". Material: State the wood species, such as pine, poplar, birch, etc., and whether it has undergone anti-corrosion, waterproofing, or other treatments. Specifications and Dimensions: Declare the length, width, thickness, and other dimensions of the formwork, usually expressed in millimeters or centimeters, such as 1830mm×915mm×18mm. Processing Technique: Describe the processing method of the formwork, such as whether it is faced, film-coated, grooved, drilled, etc., and the surface treatment condition. Use: Clearly state that it is used for concrete pouring and molding, such as in buildings, bridges, tunnels, and other projects. Brand: If there is a brand, declare the brand name; if no brand, fill in "None". Model: Declare the model or item number of the product for easy identification. Customs declaration example: Product Name: Wooden concrete formwork Material: Pine, surface covered with phenolic resin film Specifications and Dimensions: 1830mm×915mm×18mm Processing Technique: Multi-layer gluing, double-sided film coating, four-edge sealing Use: Used for building concrete pouring and molding Brand: None Model: F-18 HS Code: 441840 Failure to distinguish whether surface film coating or coating has been applied, which may affect classification. Incomplete declaration of specifications and dimensions, leading to customs questioning. Misreporting wooden concrete formwork as plywood (4412) or wood products (4421).

Core basis for classification: According to the Harmonized Commodity Description and Coding System, heading 4418 covers builders' joinery and carpentry of wood. Wooden concrete formwork is a wood product specifically used for concrete engineering, usually made of multi-layer wooden boards or plywood, possibly treated with waterproofing, film coating, etc. Its classification depends on: 1) whether the commodity is made of wood; 2) whether it is specifically used for building concrete formwork; 3) whether it exceeds the scope of other headings (such as 4412 plywood). If the formwork is made only of single-layer wooden boards without further processing, it may be classified under 4407 or 4412; but if processed into formwork shape and having a specific use, it is classified under 4418.40. 4412 Plywood, veneered panels and similar laminated wood: 4412 is plywood and other panels, not made into specific building formwork shapes; 441840 is a wood product already processed into concrete formwork, usually with specific dimensions and edge treatment. 4418.10 Wooden windows, window frames: 4418.10 is wooden windows and their frames for buildings, used as windows; 441840 is concrete formwork, used for concrete molding. 4418.20 Wooden doors and their frames: 4418.20 is wooden doors and their frames, used for building entrances and exits; 441840 is concrete formwork, used in the construction process. 4421 Other articles of wood: 4421 is articles of wood not elsewhere specified; if concrete formwork does not meet the description of 4418, it may be classified under 4421; but 441840 is specifically named and should be given priority. Is the commodity specifically used for concrete pouring and molding? Is it made of wood or wood-based materials? Has it been processed (such as film coating, grooving) to make it formwork? Does it have the characteristics of builders' joinery and carpentry of wood? Is it excluded from 4412 (plywood) or 4421 (other articles of wood)?

What is the HS code for wooden concrete formwork? The HS code for wooden concrete formwork is 441840. This code belongs to Chapter 44 (Wood and articles of wood), heading 4418 (Builders' joinery and carpentry of wood), subheading 4418.40 (Wooden concrete formwork). How to determine whether wooden concrete formwork should be classified under 441840? Mainly check whether the commodity is specifically used for concrete engineering, whether it is made of wood, and whether it has been processed into formwork shape. If it is just general plywood not made into formwork, it may be classified under 4412; if it has been processed into formwork of specific dimensions and use, it is classified under 441840. What key elements need to be provided when declaring 441840? Need to declare product name, material, specifications and dimensions, processing technique, use, brand, model, etc. Among these, material and processing technique are particularly important and affect classification. What is the main difference between wooden concrete formwork and plywood (4412)? Plywood (4412) is a panel, not made into specific building formwork; while 441840 is a wood product already processed into concrete formwork, usually with specific dimensions, edge treatment, and surface film coating, specifically used for concrete pouring. If wooden concrete formwork has been film-coated, does it affect classification? Film coating treatment usually does not affect classification under 441840, because film coating is to enhance the waterproof and durability of the formwork and still belongs to builders' joinery and carpentry of wood. However, if the film coating material is non-wood and changes the essential character of the commodity, reconsideration is needed. What is the export tax rebate situation for wooden concrete formwork? Export tax rebate rates change, and the latest export tax rebate rate database should be consulted. Usually, the export tax rebate rate for wood products is 9% or 13%, but the latest regulations of customs and tax authorities shall prevail. What should be noted when declaring wooden concrete formwork sold via cross-border e-commerce? For cross-border e-commerce sales of such commodities, declaration should be made according to general trade or cross-border e-commerce modes, providing complete declaration elements, paying attention to fumigation certificates for wooden packaging, and confirming compliance with the wood quarantine requirements of the destination country. Where can I query the latest tax rates and regulatory conditions for 441840? You can query the website of the General Administration of Customs of China, HS code query platforms, or consult professional customs brokers.
