Short answer
Under General Rules for Interpretation (GRI) of the Customs Tariff, mixed-blend fabrics are classified according to the component textile fiber that predominates by weight (e.g., if a fabric is 60% polyester and 40% cotton, it takes the synthetic HSN chapter).
Always verify constituent fiber percentages with your mill before generating GST invoices. Search exact chapters using our Textile HSN & GST Finder[cite: 1, 4].
