Chapter 52 covers the international trade classification of cotton and cotton textiles, including raw cotton, cotton waste, cotton carded or combed, cotton yarn, and cotton woven fabrics. This chapter does not include cotton knitted or crocheted fabrics (Chapter 60) or cotton textile fabrics for industrial use (Chapter 59). The core lies in hierarchical classification based on degree of processing (not carded/combed vs. carded/combed), blending ratio, weave structure, and weight per square meter. Heading 5211 specifically refers to cotton woven fabrics containing less than 85% cotton, mixed mainly or solely with man-made fibres. It is further subdivided by weave structure (plain weave, twill, etc.) and weight per square meter (not exceeding 200g, exceeding 200g). This heading does not include cotton fabrics with cotton content ≥85% (headings 5208-5210) or blended fabrics predominantly of man-made filament (Chapter 54). First 2 digits 52: represents Chapter 52 "Cotton", under which all cotton textile products are classified. Digits 3-4: 11 represents heading 5211, i.e., "Dyed plain weave cotton fabrics, containing <85% cotton, mixed with man-made fibres, weighing >200g/m²". Digits 5-6: 31 is subheading 5211.31, further limited to "dyed" plain weave fabrics. Note: under heading 5211 there are also 5211.11 (unbleached), 5211.21 (bleached), 5211.41 (yarn-dyed), etc. Subheading 31 specifically refers to dyed. This product contains <85% cotton and is mixed with man-made fibres, weighs >200g/m², has a plain weave structure, and has been dyed. According to the General Rules for the Interpretation of the Harmonized System, cotton blended woven fabrics with cotton content below 85% should be classified under heading 5211 rather than 5208-5210; plain weave structure and weight exceeding 200g/m² further narrow it to 5211.31; the dyeing process distinguishes it from unbleached, bleached, or yarn-dyed, so it is not classified under 5211.11, 5211.21, or 5211.41.

Product Name: The standard name of the declared commodity should include key characteristics such as "dyed", "plain weave", "cotton blend", e.g., "Dyed plain weave cotton fabric". Composition Content: Accurately declare the percentage of cotton and man-made fibres. Cotton content must be below 85%, and the specific type of man-made fibre (e.g., polyester staple fibre) must be indicated. Weight Per Square Meter: Declare the fabric weight in grams per square meter, which must be greater than 200g/m², usually expressed as "g/m²", and must be consistent with the test report. Weave Structure: Clearly state plain weave, and may indicate the interlacing pattern of warp and weft yarns, such as "one-up-one-down plain weave". Dyeing and Finishing Method: Declare as "dyed", distinguishing it from bleached, unbleached, yarn-dyed, etc. The dyeing process (e.g., piece dyeing) should be indicated. Width: Declare the effective width of the fabric, usually expressed in centimeters or inches, which affects classification and tariffs. Brand and Model: If there is a brand, declare the brand name; if no brand, declare "no brand". The model can be filled in with the production batch number or article number. Processing Technique: Briefly describe the weaving and dyeing/finishing process, such as "woven → dyed → heat-set", to assist in classification determination. Customs declaration example: Product Name: Dyed plain weave cotton fabric Composition Content: Cotton 60%, Polyester staple fibre 40% Weight Per Square Meter: 220g/m² Weave Structure: Plain weave Dyeing and Finishing Method: Dyed (piece dyed) Width: 150cm Brand: No brand Model: 2024-01 Processing Technique: Weaving → Dyeing → Heat-setting → Inspection HS Code: 52113100 Cotton content must be below 85%. If equal to or exceeding 85%, it should be classified under 5208-5210, not 5211. Weight per square meter must be greater than 200g. If equal to or less than 200g, it should be classified under 5210 or other subheadings of 5211. Dyeing and yarn-dyeing are easily confused. Yarn-dyed fabric should be classified under 5211.41, not 5211.31.

The core classification basis is: 1) Cotton content below 85% and mixed mainly with man-made fibres; 2) Weight per square meter exceeding 200g; 3) Plain weave structure; 4) Dyeing process. It is necessary to combine the subheading notes of the Tariff and the General Rules for Interpretation, prioritizing the determination of heading by composition and weight, then determining the subheading by weave structure and dyeing/finishing method. If the blended man-made fibre is filament, it may be classified under Chapter 54; if it is staple fibre, it is classified under Chapter 52. 520931 Dyed plain weave cotton fabric, containing ≥85% cotton, weighing >200g/m²: This code has cotton content ≥85%, while 521131 requires cotton content <85%. The core difference is whether the cotton content reaches 85% or above. 521041 Dyed plain weave cotton fabric, containing <85% cotton, mixed with man-made fibres, weighing ≤200g/m²: This code has weight per square meter not exceeding 200g, while 521131 requires exceeding 200g. Weight is the key to distinguishing the two. 521141 Yarn-dyed plain weave cotton fabric, containing <85% cotton, mixed with man-made fibres, weighing >200g/m²: This code is yarn-dyed fabric, i.e., yarns are dyed first and then woven, while 521131 is dyed fabric (dyed after weaving). The dyeing and finishing methods are different. 551511 Dyed polyester staple fibre plain weave fabric, mixed with cotton, weighing >200g/m²: This code is predominantly of man-made fibre (cotton content <50% or man-made fibre weight is greater), while 521131 is predominantly cotton but with cotton content <85%. The weight ratio of cotton to man-made fibre must be compared. 521112 Unbleached plain weave cotton fabric, containing <85% cotton, mixed with man-made fibres, weighing >200g/m²: This code is unbleached, while 521131 is dyed. The dyeing/finishing state is the main difference. Is the cotton content indeed below 85%? Is the weight per square meter greater than 200g? Is the weave structure plain weave? Is the dyeing/finishing method dyeing (not yarn-dyed, not bleached)? Is the blended man-made fibre staple fibre (not filament)?

How to inquire about the import tariff rate for 521131? You can log on to the official website of the General Administration of Customs of China or the International Trade Single Window and enter HS code 52113100 to inquire about the latest tariff rate. Note that tariff rates vary by country, trade agreement (such as RCEP), and annual adjustments. It is recommended to refer to official real-time data. If the cotton content is exactly 85%, which code should it be classified under? If the cotton content equals 85%, it does not meet the "containing <85% cotton" condition of 521131 and should be classified under heading 5209 (dyed plain weave fabric containing ≥85% cotton and weighing >200g/m²), specifically subheading 520931. How to determine plain weave structure? Plain weave structure means that warp and weft yarns interlace every other yarn, presenting a "one-up-one-down" pattern. It can be observed by magnifying glass on both sides of the fabric; if the interlacing points are uniform and dense, it is plain weave. What is the difference between dyeing and yarn-dyeing? Dyeing means weaving yarns into fabric first, then dyeing the fabric; yarn-dyeing means dyeing yarns first, then weaving the dyed yarns into fabric. Yarn-dyed fabric usually has more complex patterns and is classified under 521141. If the blended man-made fibre is filament, can it still be classified under 521131? No. If the man-made fibre is filament, it falls within the scope of Chapter 54 and should be classified under headings such as 5407 or 5408. 521131 only applies to fabrics blended with man-made staple fibres. How is the weight per square meter determined during declaration? It should be determined based on laboratory test reports or specification sheets provided by suppliers, using standard methods (such as GB/T 4669). The declared weight must be greater than 200g/m², otherwise it may be classified under other codes. What is the difference between 521131 and 521132? 521132 is dyed cotton twill weave fabric (containing <85% cotton, mixed with man-made fibres, weighing >200g/m²), while 521131 is plain weave. The difference lies in the weave structure. For cross-border e-commerce retail export of this commodity, is it also necessary to declare under 521131? Yes, whether general trade or cross-border e-commerce, export declaration must use the correct HS code. 521131 applies to goods that meet the description. Enterprises should declare truthfully, otherwise they may face customs penalties.
