Chapter 44 covers wood and articles of wood, including logs, sawn timber, wood chips, wood flour, articles of wood other than wood pulp, as well as charcoal, cork articles, articles of plaiting materials, etc. This chapter is the core chapter in the HS system for wood-related products, covering a wide range from raw materials to finished products, but excluding furniture (Chapter 94), toys (Chapter 95), and goods of other specific chapters. Heading 4418 covers builders' joinery and carpentry of wood, mainly including wooden articles for construction such as beams, columns, boards, shingles, windows, doors and their frames, flooring, formwork, etc., as well as wooden concrete formwork, wooden shingles, wooden railings, etc. However, it excludes wooden furniture (Chapter 94), wooden toys (Chapter 95), and wooden tools (Chapter 82), etc. Code 441890 is a 6-digit subheading: the first 2 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 "90" represent the subheading "Other", i.e., builders' joinery and carpentry of wood not specifically named under other subheadings of 4418 (such as 441811 to 441889). This subheading is a residual subheading covering all other builders' joinery and carpentry of wood not elsewhere specified. The goods are builders' joinery and carpentry of wood, but are not specifically named under other subheadings of 4418 (such as wooden windows, wooden doors, wooden formwork, etc.), and are therefore classified under 441890 "Other". If they were wooden furniture, they would be classified under Chapter 94; if wooden toys, under Chapter 95; if wooden tools, under Chapter 82.

Product Name: The specific name of the declared goods, which should accurately reflect the product's attributes, such as "wooden construction beam", "wooden railing", etc. Material: Declare the wood species, such as pine, oak, fir, etc., and whether it has undergone preservative treatment, drying, or other processing. Use: Clearly declare that it is for construction use, such as structural support, decoration, formwork, etc. Specifications and Dimensions: Declare length, width, thickness, and other dimensional information, as well as whether it has undergone processing (such as drilling, grooving). Processing Technique: Describe the processing method, such as sawing, planing, splicing, preservative treatment, etc. Brand: If there is a brand, declare the brand name; if there is no brand, declare "none". Model: If there is a model, declare the model; if there is no model, declare "none". Product Name: Wooden construction beam; Material: Pine; Use: Building structural support; Specifications and Dimensions: Length 300cm x Width 15cm x Thickness 10cm; Processing Technique: Sawing, planing, preservative treatment; Brand: None; Model: None. Mistakenly classifying builders' joinery and carpentry of wood under other subheadings of 44.18 when they may actually belong to specific subheadings of 44.18 such as wooden windows or wooden doors. Failing to declare the wood species, making it impossible to determine whether it involves endangered wood, affecting license management. Incorrectly classifying deeply processed wooden articles (such as those already assembled into furniture) under 44.18 when they should be classified under Chapter 94.

The core basis for classification is the Harmonized Commodity Description and Coding System and national subheading notes. Heading 44.18 covers builders' joinery and carpentry of wood, but only includes other builders' joinery and carpentry of wood not named under other subheadings. When determining, consideration should be given to: 1) whether the goods are for construction use; 2) whether they have undergone joinery and carpentry processing; 3) whether they are already named under other subheadings. If they are wooden furniture, toys, or tools, they are classified under Chapters 94, 95, and 82 respectively. 441811 Wooden windows and their frames: 441811 specifically refers to wooden windows and their frames, while 441890 covers other builders' joinery and carpentry of wood, excluding windows. 441819 Other wooden doors and their frames: 441819 specifically refers to wooden doors and their frames, while 441890 excludes doors. 441840 Wooden concrete formwork: 441840 specifically refers to wooden concrete formwork, while 441890 excludes formwork. 441879 Other wooden flooring: 441879 specifically refers to assembled wooden flooring, while 441890 excludes flooring. 940360 Other wooden furniture: 940360 covers wooden furniture, while 441890 covers builders' joinery and carpentry of wood; the uses are different. Are the goods used for construction? Have they undergone joinery and carpentry processing? Are they already named under other subheadings of 4418? Do they belong to excluded chapters such as furniture, toys, or tools? Does the material involve endangered wood?

What is the difference between 441890 and 441899? 441890 is the 6-digit subheading for "Other builders' joinery and carpentry of wood", while 441899 is an 8-digit or 10-digit national subheading that may be further subdivided. In China Customs' Tariff Schedule, 441890 may be subdivided into 44189010, 44189090, etc.; please consult the latest tariff schedule for details. How to distinguish builders' joinery and carpentry of wood from wooden furniture? Builders' joinery and carpentry of wood generally refers to fixed-installation wooden articles used for building structures or decoration, such as beams, columns, railings, etc.; wooden furniture refers to movable wooden articles used for sitting, lying, or storage, such as tables, chairs, cabinets, etc. If goods have characteristics of both, they should be classified according to their principal use. What documents are required to declare 441890? Generally, basic documents such as contract, invoice, packing list, and bill of lading are required. If endangered wood is involved, a CITES permit for import/export of endangered species is required. In addition, material certificates, processing technique descriptions, etc., may be required. What is the import tariff rate for 441890? The tariff rate varies depending on the country, trade agreements, country of origin of the goods, and other factors. It is recommended to consult the latest Tariff Schedule of the General Administration of Customs of China or query through the "Internet + Customs" platform. MFN rates, agreement rates, etc., may differ. What is the export tax rebate for wooden construction articles? Export tax rebate rates are periodically adjusted by the State Administration of Taxation, and different wooden articles may have different rebate rates. It is recommended to consult the latest export tax rebate rate database or consult the local tax authority. Does 441890 involve endangered species management? If the wood used in the wooden articles belongs to species listed in the Appendices of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) or wild plants under special state protection, a permit for import/export of endangered species is required. Common endangered woods include rosewood, red sandalwood, etc. How to query the regulatory conditions for 441890? You can query the regulatory conditions by entering the HS code in the "Import and Export Tariff Query" system on the official website of the General Administration of Customs of China. Regulatory conditions include A (Customs Clearance Form for Inbound Goods), B (Customs Clearance Form for Outbound Goods), F (Import Permit for Endangered Species), etc. Can 441890 be classified under other subheadings of 4418? If the goods meet the specific description of other subheadings of 4418, such as wooden windows, wooden doors, wooden formwork, etc., they should be classified under the corresponding subheading first. Only when the goods do not belong to any other subheading should they be classified under 441890 "Other".
