Chapter 52 covers cotton and cotton woven fabrics, including raw cotton, cotton waste, carded cotton, cotton yarn, and cotton woven fabrics. This chapter is subdivided by degree of processing and fabric structure, forming a complete chain from raw material to finished product. Heading 5209 belongs to the third level of this chapter and specifically refers to cotton woven fabrics containing ≥85% cotton, further divided by weight per square meter, weave structure, and processing method. Heading 5209 covers cotton woven fabrics containing ≥85% cotton and weighing more than 200g per square meter. Under this heading, further subdivision is based on fabric weave (plain weave, twill, etc.), whether yarn-dyed, whether three-thread or four-thread twill, etc. 5209 forms a weight boundary with 5208 (weight ≤200g/㎡) and a composition boundary with 5210 (cotton content <85%). First 2 digits 52: indicates Chapter 52, i.e., cotton and cotton woven fabrics. Digits 3-4, 09: indicates heading 5209, i.e., cotton woven fabrics containing ≥85% cotton and weighing >200g per square meter. Digits 5-6, 43: under 5209, subheading 43 specifically refers to yarn-dyed three-thread or four-thread twill woven fabrics, i.e., woven from warp and weft yarns that have been pre-dyed, and using a three-thread or four-thread twill weave. This subheading does not distinguish whether bleached or mercerized, but must satisfy both conditions of yarn-dyed and twill weave. This product contains ≥85% cotton, weighs >200g per square meter, and is a yarn-dyed three-thread or four-thread twill weave, fully conforming to the description of 5209.43. It cannot be classified under 5208 (weight ≤200g), nor under 5210 (cotton content <85%). If it were plain weave or two-thread twill, it should be classified under other subheadings of 5209; if bleached or unbleached, it would be classified under subheadings before 5209.4.

Product Name: Should be described in detail as yarn-dyed cotton three-thread or four-thread twill woven fabric, containing ≥85% cotton, weight per square meter >200g Composition Content: Indicate cotton content percentage, such as 100% cotton or cotton 85% or above, and list other fiber components Weight Per Square Meter: Declare specific gram weight, such as 210g/㎡, must be greater than 200g Fabric Weave: Clearly specify three-thread twill or four-thread twill, may indicate twill direction Dyeing and Finishing Method: Indicate yarn-dyed, i.e., yarns are dyed before weaving Width: Declare fabric width, such as 150cm, affects measurement and classification Brand or Manufacturer: If there is a brand, declare it; if no brand, fill in "None" Use: Briefly describe final use, such as clothing, home textiles, etc. Product Name: Yarn-dyed cotton three-thread twill woven fabric; Composition Content: 100% cotton; Weight Per Square Meter: 215g/㎡; Fabric Weave: Three-thread twill; Dyeing and Finishing Method: Yarn-dyed; Width: 150cm; Brand: None; Use: For clothing. Mistakenly declaring yarn-dyed fabric as piece-dyed fabric, leading to classification under other subheadings of 5209.4 rather than 5209.43. Inaccurate weight declaration; if actual weight ≤200g/㎡, it should be classified under 5208 rather than 5209. Ignoring the weave requirement of three-thread or four-thread twill, mistakenly reporting as two-thread twill or plain weave.

Core classification basis: 1) Cotton content ≥85%; 2) Weight per square meter >200g; 3) Yarn-dyed (yarns dyed before weaving); 4) Three-thread or four-thread twill weave. All four conditions must be met simultaneously to classify under 5209.43. If any condition is not met, consider 5208, other subheadings of 5209, or 5210. 520942 Yarn-dyed cotton twill woven fabric, containing ≥85% cotton, weight per square meter >200g, two-thread twill: 520942 is two-thread twill, while 520943 is three-thread or four-thread twill. Weave difference is the core distinction. 520941 Yarn-dyed cotton plain weave fabric, containing ≥85% cotton, weight per square meter >200g: 520941 is plain weave, 520943 is twill weave, fabric structure is different. 520949 Yarn-dyed cotton other woven fabric, containing ≥85% cotton, weight per square meter >200g: 520949 is other weaves, such as jacquard, satin, etc., while 520943 specifically refers to three-thread or four-thread twill. 521041 Yarn-dyed cotton blended woven fabric, containing <85% cotton, weight per square meter >200g, three-thread or four-thread twill: 521041 contains <85% cotton, while 520943 requires ≥85% cotton, composition is different. 520843 Yarn-dyed cotton three-thread or four-thread twill woven fabric, containing ≥85% cotton, weight per square meter ≤200g: 520843 weight per square meter ≤200g, while 520943 weight per square meter >200g, weight boundary is different. Is cotton content ≥85%? Is weight per square meter >200g? Is it yarn-dyed (yarns dyed first)? Is it three-thread or four-thread twill weave? Is it distinguished from adjacent codes such as 5208, 5210?

How to inquire about the import tax rate for 520943? You can check through the General Administration of Customs website, China International Trade Single Window, or third-party inquiry platforms by entering HS code 520943, selecting the destination country and country of origin, to display MFN rates, agreement rates, etc. Note that tax rates are subject to policy adjustments; it is recommended to refer to the latest official data. What is the difference in classification between yarn-dyed and piece-dyed? Yarn-dyed means yarns are dyed before weaving; piece-dyed means fabric is dyed after weaving. 520943 explicitly requires yarn-dyed; if piece-dyed, it cannot be classified under this code and may be classified under other subheadings of 5209 (such as 5209.49). Dyeing and finishing process certification is required for declaration. How to distinguish three-thread twill from four-thread twill? Three-thread twill means the interlacement point of warp and weft appears every two yarns; four-thread twill every three yarns. It can be observed through a magnifying glass on the fabric texture or by checking technical specification sheets. Accurate description is required for declaration, otherwise it may be classified under 520942 (two-thread twill) or 520949 (other). If cotton content is 84%, which code should it be classified under? If cotton content is <85%, it cannot be classified under 5209 and should be classified under 5210 (cotton woven fabrics containing <85% cotton). The specific subheading is determined by weight, weave, and dyeing method, such as 5210.41 (yarn-dyed three-thread or four-thread twill, >200g). What is the main difference between 520943 and 520942? Both are yarn-dyed twill fabrics containing ≥85% cotton and weighing >200g per square meter, but 520942 is two-thread twill, 520943 is three-thread or four-thread twill. Different weaves lead to different classifications; the number of twill threads must be specified for declaration. What are the consequences of omitting the brand during declaration? It may affect customs valuation and intellectual property protection. If infringement is involved, the goods may be detained. It is recommended to declare the brand truthfully; if no brand, fill in "None". What documents are required for cross-border e-commerce retail export of 520943? Generally, commercial invoice, packing list, customs declaration form, contract, etc. are required. If a brand is involved, authorization letter is required. Specific requirements are subject to customs; it is recommended to consult a customs broker in advance. How to determine if the fabric is three-thread or four-thread twill? Refer to the fabric weave diagram or use a fabric analysis glass. Three-thread twill has warp interlacement points of 2 up 1 down or 1 up 2 down; four-thread twill is 3 up 1 down or 1 up 3 down. It can also be sent to a professional institution for an identification report.
