Chapter 54 covers man-made filaments, including synthetic filaments and artificial filaments. This chapter ranges from raw filaments (such as polyester, nylon, acrylic, etc.) to yarns and woven fabrics made from these filaments. However, this chapter does not include man-made staple fibers (Chapter 55) and filament wadding, nonwovens, etc. (Chapter 56). Chapter 54 is a key chapter in the midstream of the textile industry chain, involving huge international trade volumes of filament yarns and their fabrics. Heading 5407 specifically refers to woven fabrics of synthetic filament yarn, including various types of fabrics woven from synthetic filament yarn as raw material. Regardless of whether other textile materials are blended in, as long as the synthetic filament content by weight is 85% or more, or even if below 85% but determined by the classification rules with the main blended material (such as cotton, wool, etc.) to fall under this heading. Under this heading, it is further subdivided by fabric processing method (bleached, dyed, yarn-dyed, printed, etc.) and fiber type. Code 540772 has 6 digits. The first 2 digits "54" represent Chapter 54 (man-made filaments). Digits 3-4 "07" represent heading 5407 (woven fabrics of synthetic filament yarn). Digits 5-6 "72" represent subheading 5407.72, specifically "dyed" woven fabrics of other synthetic filament yarn. The 5th digit "7" indicates classification by processing method under the subheading level (e.g., 5407.1 for unbleached or bleached, 5407.2 for dyed, etc.), and the 6th digit "2" further distinguishes fiber types, here specifically referring to other synthetic filaments excluding specific types such as polyester, nylon, etc. Therefore, the complete meaning of 540772 is: dyed woven fabrics of other synthetic filament yarn. This commodity is classified under 540772 rather than adjacent codes, primarily because: 1) The raw material is synthetic filament (Chapter 54), not staple fiber (Chapter 55); 2) The fabric has undergone dyeing processing, not bleaching, yarn dyeing, or printing (corresponding to 5407.71, 5407.73, etc.); 3) The fiber type is "other synthetic filament," i.e., not belonging to named fibers such as polyester (5407.61), nylon (5407.62), etc. If it were dyed woven fabric of polyester filament, it should be classified under 540761; if it were blended and synthetic filament is not the main component, it might be classified under Chapter 55 or other headings.

Product Name: The standard name of the declared commodity, which should include key information such as fiber type, processing method, fabric structure, e.g., "dyed woven fabrics of other synthetic filament yarn." Fiber Composition and Content: List all fiber types and their respective weight percentages, e.g., "polyester filament 60%, viscose filament 40%." Attention should be paid to the total synthetic filament content. Weaving Method: State whether it is woven, knitted, or other. This code is limited to woven fabrics, so "woven" must be specified. Dyeing and Finishing Process: Indicate "dyed," distinguishing it from bleached, yarn-dyed, printed, etc. If yarn-dyed, it should be classified under 540773. Width: Declare the actual width of the fabric in centimeters, which affects the division of certain subheadings. Weight per Square Meter: Declare the weight per unit area (g/m²), used to distinguish light from heavy fabrics; some subheadings have weight requirements. Brand and Model: If there is a brand, declare the brand name (e.g., "XX brand"); if no brand, declare "no brand." The model can be filled with production batch number or specification code. Packaging Specifications: State the packaging form such as roll, piece, etc., and the length or weight per roll/piece. Product Name: dyed woven fabrics of other synthetic filament yarn; Fiber Composition and Content: polyester filament 70%, viscose filament 30%; Weaving Method: woven; Dyeing and Finishing Process: dyed; Width: 150 cm; Weight per Square Meter: 120 g; Brand: no brand; Model: 2024-01; Packaging Specifications: roll packing, 100 meters per roll. Mistaking "other synthetic filament" as including all synthetic fibers; in fact, polyester, nylon, etc. already have separate subheadings and must be accurately distinguished. Confusing dyeing with yarn dyeing: yarn-dyed fabric refers to yarn being dyed first and then woven, classified under 540773, while this code is for fabric dyeing. Inaccurate declaration of fiber content: if synthetic filament content is below 85% and blended with cotton, it may be classified under Chapter 55; attention must be paid to blending rules. Omitting width and weight: these two elements are key to customs valuation and classification; missing them may lead to rejection or inspection.

Core classification criteria: 1) The raw material must be synthetic filament and must not belong to named fibers such as polyester or nylon, otherwise it should be classified under the corresponding subheading; 2) The fabric must be woven, excluding knitted fabrics; 3) The processing method must be dyeing, excluding bleaching, yarn dyeing, and printing; 4) If blended, it must be determined by weight according to the classification rules with the main blended material (such as cotton, wool, etc.); generally, if synthetic filament content is 85% or more, it falls under this heading, otherwise it may be classified under Chapter 55 or other headings. 540761 Dyed woven fabrics of polyester filament yarn: Different fiber type: 540761 specifically refers to polyester filament, while 540772 is other synthetic filament (such as acrylic, polypropylene, etc.). If it is dyed polyester filament fabric, it should be classified under 540761. 540773 Yarn-dyed woven fabrics of other synthetic filament yarn: Different processing method: 540773 is yarn-dyed (yarn dyed first and then woven), while 540772 is fabric dyeing. This can be determined by observing whether the yarn is dyed throughout. 540782 Dyed woven fabrics of other synthetic filament yarn, mixed: Different blending ratio: 540782 refers to synthetic filament blended with other fibers, with filament content below 85%, while 540772 generally refers to pure woven or fabrics with filament content ≥85%. 551512 Dyed woven fabrics of polyester staple fiber: Different fiber length: 551512 is staple fiber (limited length), while 540772 is filament (continuous fiber). This can be distinguished by burning test or microscope observation. 590390 Other coated woven fabrics: Whether coated: if the fabric surface has a coating (such as PU coating), it should be classified under 5903, not 540772. It is necessary to confirm whether coating finishing has been applied. Is the fiber synthetic filament? Has it undergone dyeing processing? Does it belong to named fibers such as polyester or nylon? Is the synthetic filament content ≥85%? Is it woven fabric rather than knitted fabric?

How to determine whether a piece of fabric belongs to 540772? First confirm that the fiber is synthetic filament (such as acrylic, polypropylene, etc., not polyester or nylon), then confirm that it has undergone dyeing processing and is woven fabric. If it contains other fibers, calculate whether the synthetic filament content is ≥85%. Also, exclude special processes such as coating and yarn dyeing. What is the difference between 540772 and 540761? Both are dyed woven fabrics of synthetic filament yarn, but the fiber types differ: 540761 specifically refers to polyester filament, while 540772 refers to other synthetic filament (such as acrylic, polypropylene, spandex, etc.). If the fabric is dyed polyester filament fabric, it should be classified under 540761. If the fabric is yarn-dyed, which code should it be classified under? Yarn-dyed woven fabrics of other synthetic filament yarn should be classified under 540773. Yarn dyeing means the yarn is dyed first and then woven, while 540772 is fabric dyeing. This can be distinguished by unraveling the yarn and observing whether the color penetrates evenly. How should blended fabrics be classified? If synthetic filament is blended with other fibers and the filament content is ≥85%, it is still classified under 540772; if the filament content is <85%, it should be classified according to blending rules under 540782 (dyed woven fabrics of other synthetic filament yarn, mixed) or other chapters. The specific classification depends on the type and proportion of blended fibers. What key elements should be noted when declaring? Fiber composition and content, weaving method, dyeing and finishing process, width, weight per square meter, brand and model must be declared. These elements directly affect classification and valuation; missing them may lead to rejection or inspection. How to check the tariff rate for 540772? Tariff rates change; you can check through the General Administration of Customs website, China International Trade Single Window, or professional tariff inquiry tools by entering code 540772 and conditions such as country of origin and trade mode. It is recommended to refer to the latest official data. If the fabric has a slight coating, can it still be classified under 540772? If the coating is only used to enhance hand feel or appearance and does not change the basic characteristics of the fabric, it may still be classified under 540772; but if the coating is obvious (such as waterproof coating), it is usually classified under 5903. It is recommended to judge based on the nature and weight of the coating, and consult customs if necessary. What are the considerations for cross-border e-commerce retail export of such fabrics? It is necessary to accurately declare the product name, composition, use, etc., to avoid customs clearance delays caused by classification errors. Also note that the destination country's HS code may differ; it is recommended to check the destination country's tariffs and access requirements in advance. Small parcel exports can simplify declaration but must be truthful.
