HSN Code 6703 refers to "Human hair, dressed, thinned, bleached or otherwise worked; wool, other animal hair or other textile materials, prepared for use in making wigs or the like (excluding natural plaits of human hair, whether or not washed and degreased, but not otherwise processed)." This classification code is essential for identifying hair and textile materials used in the production of wigs and similar items for import/export purposes based on their nature, composition, and intended use. Common products under HSN Code 6703 include processed human hair, synthetic hair extensions, and various types of animal hair used in wig making. Additionally, the GST rate for hair and textile materials under this code supports accurate trade compliance.
