Chapter 54 covers man-made filament yarns, including yarns, woven fabrics, and articles thereof. This chapter is divided into two sub-chapters: the first sub-chapter (5401-5406) covers man-made filament yarns, and the second sub-chapter (5407-5408) covers woven fabrics of man-made filament yarns. Filament refers to continuous fibers, as distinguished from staple fibers (Chapter 55). Goods of this chapter are widely used in apparel, home textiles, industrial applications, etc. Classification requires attention to fiber composition, processing methods (such as texturing, twisting), fabric structure, etc. Heading 5407 covers woven fabrics of synthetic filament yarns, including woven fabrics made from synthetic filament yarns such as polyamide (nylon), polyester, polyacrylonitrile, etc. Under this heading, goods are further subdivided by fiber type, content, whether bleached, dyed, yarn-dyed, etc. Yarn-dyed means the yarns are dyed before weaving, as distinguished from piece-dyed fabrics. Fabrics of heading 5407 are typically used for apparel, bags, tents, etc. Classification requires determination of fiber composition and processing technique. First 2 digits 54: Chapter 54, man-made filament yarns. Digits 3-4, 07: Heading 5407, woven fabrics of synthetic filament yarns. Digits 5-6, 43: Subheading 540743, yarn-dyed nylon woven fabrics, containing >= 85% nylon. Specifically: under Chapter 54, 5407 represents woven fabrics of synthetic filament yarns; under 5407, subdivided by fiber type and content, 540743 specifically refers to yarn-dyed woven fabrics with nylon (polyamide) filament content >= 85%. If nylon content is less than 85%, it is classified under other subheadings. This code applies to yarn-dyed fabrics of pure nylon or nylon blended with other fibers but with nylon predominating. This product is a yarn-dyed nylon woven fabric with nylon content >= 85%, meeting the description of subheading 540743. The yarn-dyeing process is distinguished from dyeing or printing, and the nylon content reaches 85% or above, excluding fabrics with higher blend ratios. Adjacent codes such as 540741 (bleached nylon woven fabrics) or 540742 (dyed nylon woven fabrics) do not apply due to different processing methods; if nylon content is less than 85%, it is classified under 540749 or other subheadings. Therefore, this code accurately reflects the fiber composition and processing method.

Product Name: The Chinese and foreign language names of the declared goods, which should accurately reflect the fabric composition and processing method, such as 'yarn-dyed nylon woven fabric'. Fiber Composition and Content: List the names and percentages of each fiber, such as nylon 85%, spandex 15%, which must meet the subheading requirements. Processing Technique: Indicate whether the yarn is yarn-dyed, whether the fabric is bleached, dyed, printed, etc., such as 'yarn-dyed'. Weave Structure: Describe the weave of the fabric, such as plain weave, twill, satin, etc., and provide the number of warp and weft yarns per square centimeter if necessary. Specifications and Model: Including width, weight, yarn fineness, etc., such as width 150cm, weight 120g/m2. Brand and Model: If there is a brand, declare the brand name (if no brand, declare 'none'), as well as the model or article number. Packaging Specifications: Declare the packaging method and length or weight per piece, such as roll packaging, 100 meters per roll. Product Name: Yarn-dyed nylon woven fabric; Fiber Composition: Nylon 100%; Processing Technique: Yarn-dyed; Weave Structure: Plain weave; Specifications: Width 150cm, weight 110g/m2, yarn fineness 70D x 70D; Brand: None; Model: NY-2024; Packaging: Roll packaging, 200 meters per roll. Misdeclaring yarn-dyed fabric as dyed fabric, leading to classification errors. Inaccurate declaration of fiber content, such as actual nylon content of 84% reported as 85%. Failing to provide specifications such as width and weight, affecting customs valuation and classification.

The core basis for classification is: 1) Fiber type: must be synthetic filament yarn, with nylon (polyamide) content >= 85%; 2) Processing method: must be yarn-dyed, i.e., yarns dyed before weaving; 3) Fabric structure: must be woven fabric. Reference should also be made to the Import and Export Tariff and national subheading notes to ensure compliance with the description of 540743. If nylon content is less than 85%, or the processing method is not yarn-dyed, it is classified under other subheadings. 540741 Bleached nylon woven fabrics: Processing method is bleaching, not yarn-dyeing. Yarn-dyeing is dyeing yarns before weaving; bleaching is bleaching the fabric after weaving. 540742 Dyed nylon woven fabrics: Processing method is piece dyeing, i.e., dyeing the fabric after weaving, rather than dyeing the yarn first. 540743 Yarn-dyed nylon woven fabrics: This code, requiring nylon content >= 85% and yarn-dyed. 540749 Other nylon woven fabrics: Nylon content less than 85%, or nylon woven fabrics not specifically named. 540710 Woven fabrics of nylon high tenacity yarn: Uses high tenacity yarn (such as for tire cord fabric), different from ordinary yarn-dyed fabrics. Is nylon content >= 85%? Has it undergone yarn-dyeing process? Is it a woven fabric? Are complete specifications provided? Is it distinguished from adjacent codes?

How to check the import tariff rate for 540743? It can be checked through the General Administration of Customs website, China International Trade Single Window, or the Import and Export Tariff. Enter HS code 540743 to view the MFN rate, general rate, VAT rate, and regulatory conditions. Tariff rates may change; it is recommended to refer to the latest announcements. What is the difference in classification between yarn-dyed nylon fabric and dyed nylon fabric? Yarn-dyed fabric is made by dyeing yarns before weaving, classified under 540743; dyed fabric is made by dyeing the fabric after weaving, classified under 540742. The processing methods differ, and process descriptions must be provided during classification. Which code should yarn-dyed fabric with 84% nylon content be classified under? If nylon content is less than 85%, it cannot be classified under 540743 and should be classified under 540749 (other woven fabrics of synthetic filament yarns). Fiber content must be accurately declared. Is a test report required for declaration? Customs may require a fiber composition test report, especially when content is near the threshold. It is recommended to prepare a test report issued by an authoritative institution in advance to ensure accurate classification. What are the main uses of fabrics under 540743? Mainly used for apparel (such as sportswear, down jackets), bags, tents, sleeping bags, etc. Due to high nylon content, it has characteristics of abrasion resistance and light weight. If nylon fabric is coated, is it still classified under 540743? If the coating does not change the essential characteristics of the fabric, it remains classified under 540743; if the coating gives the fabric characteristics of other headings (such as plastic coating), it may be classified under Chapter 59. Judgment should be based on the coating material and process. How to distinguish between 540743 and 540710? 540710 applies to woven fabrics of high tenacity yarn, such as tire cord fabric, where yarn tenacity meets a certain standard. Ordinary yarn-dyed nylon fabric does not apply. How to fill in 'Brand' in the declaration elements? If there is a brand, fill in the brand name; if no brand, fill in 'none'. The brand must be consistent with the actual goods and cannot be fabricated. For unbranded goods, 'none' or 'no brand' may be filled in.
