Chapter 52 covers the complete industrial chain of cotton and cotton textiles, from raw cotton, cotton waste, and cotton carded or combed, to cotton yarn and cotton woven fabrics. This chapter is the core chapter for cotton commodities in the HS, involving the intersection of agricultural products and textiles. Within the chapter, items are arranged progressively by degree of processing: raw materials → yarn → fabrics, with fabrics further subdivided by weave, weight, whether bleached/dyed/yarn-dyed, etc. Heading 5208 specifically refers to cotton woven fabrics, containing ≥85% cotton, weighing ≤200g/m². This heading is further subdivided by processing technique (unbleached, bleached, dyed, yarn-dyed, printed) and fabric weave (plain weave, twill, other). Twill weave, due to its distinct texture and substantial hand feel, is widely used in apparel and home textiles, while the yarn-dyed process gives fabrics a unique appearance of dyeing before weaving. First 2 digits 52: Chapter 52, representing cotton and cotton textiles. Digits 3-4: 08: Heading 5208, referring to cotton woven fabrics containing ≥85% cotton and weighing ≤200g/m². Digits 5-6: 43: Subheading 520843, specifically yarn-dyed cotton twill woven fabrics. The 5th digit 4 represents yarn-dyed, and the 6th digit 3 represents twill weave. Progressive limitation: chapter → cotton fabric → lightweight cotton fabric → yarn-dyed twill fabric. This commodity contains ≥85% cotton, weighs ≤200g/m², and is yarn-dyed twill fabric, fully conforming to the description of 520843. It is not classified under 520842 (yarn-dyed plain weave) because the fabric weave is different; not under 520849 (yarn-dyed other weaves) because twill has a dedicated subheading; not under 5209 (weighing >200g/m²) because the weight does not match. Classification requires simultaneously satisfying four conditions: cotton content, weight, yarn-dyed, and twill.

Product Name: The standard name of the declared commodity, which should include keywords such as 'yarn-dyed', 'cotton', 'twill', and 'woven fabric'. Composition Content: The percentage of cotton content, as well as the types and percentages of other fibers. Must clearly state ≥85% cotton. Weight: The weight per square meter of fabric, in g/m². Must be ≤200g. Weaving Method: Woven (woven fabric), and specify twill weave. Dyeing Process: Yarn-dyed (dyeing yarn before weaving), distinguished from dyed fabric and printed fabric. Width: The effective width of the fabric, in centimeters. Brand or Factory Mark: If there is a brand, the brand name must be declared; if no brand, 'unbranded' may be declared. Article Number: The product number of the manufacturer or exporter, for easy identification. Product Name: Yarn-dyed cotton twill woven fabric; Composition Content: 100% cotton; Weight: 180g/m²; Weaving Method: woven twill; Dyeing Process: yarn-dyed; Width: 150cm; Brand: unbranded; Article Number: CT-180-TW. Weight unit misuse: Mistakenly writing g/m² as g/m or g/yd, resulting in classification errors. Confusion between yarn-dyed and dyed: Yarn-dyed means yarn is dyed before weaving; dyed means the fabric is dyed after weaving. False declaration of cotton content: Actual cotton content below 85% but declared as above 85%, may be inspected by customs. Twill weave not specified: Declaring only 'cotton fabric' without specifying twill, may be classified as plain weave or other weaves.

The core basis for classification is: 1) Cotton content ≥85%; 2) Weight per square meter ≤200g; 3) Yarn-dyed process; 4) Twill weave. All four conditions must be satisfied simultaneously. If cotton content is below 85%, it should be classified under Chapter 55 (blended with man-made fibers) or other headings of Chapter 52; if weight >200g, it should be classified under 5209; if plain weave, under 520842; if other weaves, under 520849. 520842 Yarn-dyed cotton plain weave woven fabric: Plain weave, warp and weft yarns interlace one over one under, relatively thin texture; twill weave has diagonal lines and a thicker hand feel. 520849 Other yarn-dyed cotton woven fabrics: Other weaves besides plain and twill, such as satin, jacquard, etc.; twill has a dedicated subheading. 520932 Dyed cotton twill woven fabric: Dyed fabric is woven first then dyed; yarn-dyed fabric is dyed first then woven; different processing techniques result in differences in appearance and color fastness. 521041 Yarn-dyed cotton blended twill woven fabric: Cotton content <85%, mainly blended with man-made fibers; 520843 requires cotton content ≥85%. 520943 Yarn-dyed cotton twill woven fabric (weight >200g): Weight >200g/m², classified under 5209; 520843 requires ≤200g/m². Is cotton content ≥85%? Is weight per square meter ≤200g? Is it yarn-dyed (dyeing yarn before weaving)? Is it twill weave? Is it a woven fabric (woven)?

How to check the import tariff rate for 520843? You can check the most-favored-nation rate, general rate, VAT rate, and regulatory conditions by entering HS code 520843 on the General Administration of Customs website, China International Trade Single Window, or professional tariff query tools. Note that rates may be adjusted with policy changes; it is recommended to refer to the latest tariff schedule. How to distinguish yarn-dyed cotton twill fabric from dyed cotton twill fabric during customs declaration? Yarn-dyed fabric is made by dyeing yarn first and then weaving; dyed fabric is made by weaving gray fabric first and then dyeing. During customs declaration, process descriptions must be provided, and production flow certificates may be required if necessary. Customs may inspect fabric surface color uniformity, yarn cross-sections, etc. If cotton content is 80% and the rest is polyester, which code should it be classified under? Cotton content below 85% cannot be classified under 520843. If blended with man-made fibers, it is mainly classified under Chapter 55, such as 5513 (lightweight blended cotton fabric). The specific classification depends on blend ratio, weight, weave, etc. If the weight is exactly 200g/m², is it classified under 520843? Yes, heading 5208 requires weight per square meter ≤200g, and 200g/m² meets the condition. If it exceeds 200g/m², it is classified under 5209. Accurate weight data must be provided during declaration to avoid disputes at the threshold value. How to determine twill weave? In twill weave, the interlacing points of warp and weft yarns form continuous diagonal lines, and the fabric surface has clear diagonal lines. Common types include 2/1 and 3/1 twill. It can be observed with a magnifying glass or by providing a fabric weave diagram. It is recommended to specify 'twill' during customs declaration and attach process descriptions. What regulatory conditions are required for exporting goods under 520843? Generally, there are no special regulatory conditions for export, but it must comply with the Import and Export Commodity Inspection Law. If brands or special processes are involved, relevant certificates may be required. The specific requirements are subject to the latest customs announcements. If yarn-dyed cotton twill fabric is used for clothing, what else should be noted during customs declaration? It should be noted whether it has been made into finished clothing. If it is fabric, it is classified under 520843; if it has been cut and sewn into clothing, it should be classified under Chapter 61 or 62. The state (gray fabric, finished fabric, clothing) must be clearly specified during customs declaration. How to avoid customs penalties caused by classification errors? Recommendations: 1) Accurately understand the commodity's composition, weight, and process; 2) Refer to customs classification decisions and pre-classification; 3) Apply for pre-classification when necessary; 4) Keep complete production records and process descriptions. Classification errors may result in tax supplements, fines, and other risks.
