📋 Code Structure

Chapter
Chapter 52 covers cotton and cotton woven fabrics, including raw cotton, cotton waste, carded cotton, cotton yarn, and cotton woven fabrics. This chapter is the core chapter for cotton textiles in the HS, involving the complete industrial chain from raw materials to finished products. Cotton woven fabrics are further subdivided based on weave type, weight, yarn structure, etc., and are widely used in apparel, home textiles, and other fields.
Heading
Heading 5208 includes cotton woven fabrics containing 85% or more cotton by weight, subdivided by weave type (plain weave, twill, etc.), weight per square meter, yarn density, etc. Goods under this heading are mostly medium to lightweight fabrics, suitable for shirts, skirts, etc.
Digit Breakdown
First 2 digits 52: Chapter 52, representing cotton and cotton woven fabrics. Digits 3-4, 08: Heading 5208, referring to cotton woven fabrics containing 85% or more cotton, weighing not more than 200 g/m².

Classification Basis
This product is 3-thread or 4-thread twill cotton fabric, containing 85% or more cotton, weighing not more than 200 g/m², which conforms to the description of subheading 520813. It is distinguished from 520812 (plain weave), 520819 (other 3-thread or 4-thread twill), 520821, etc. (bleached), because it is unbleached and has a twill weave, and is therefore classified under this code.

🎯 Classification Logic

Basis
Core basis for classification: 1. Cotton content 85% or more; 2. Weight per square meter not more than 200 g; 3. Weave is 3-thread or 4-thread twill; 4. Bleaching status (unbleached). All these conditions must be met simultaneously to classify under 520813. If cotton content is less than 85%, classify under Chapter 55; if weight exceeds 200 g, classify under 5209; if plain weave, classify under 520812.
Confused Codes:
520812 - Cotton plain weave fabric
Plain weave, not twill, with other conditions the same.
520819 - Other cotton 3-thread or 4-thread twill fabric

520821 - Bleached cotton plain weave fabric
Bleached and plain weave, weighing not more than 200 g.
520911 - Unbleached cotton plain weave fabric
Weighing more than 200 g, classified under 5209.
