Regulatory Provision
Classification rules determine the legal heading of textile products containing two or more textile materials. The combined nomenclature note 2 section xi establishes a weight-based hierarchy for such blends. This specific provision ensures that a linen-cotton blend is categorized under the material that predominates by mass.
Quantitative Logic
Determination of the primary material follows a strict quantitative assessment of weight. When a fabric contains equal parts of different fibres, the combined nomenclature note 2 section xi directs the user to the heading that occurs last in numerical order. This prevents ambiguity during the export of mixed-fibre goods from Chinese mills to European markets.
Precise laboratory testing of fibre content supports these customs declarations. Every test result must be recorded in the formal batch documentation to ensure traceability through the entire supply chain.
Legal Boundary
Exceptions to the weight rule apply when specific headings cover the entire product as a mixture. The combined nomenclature note 2 section xi does not apply to goods where one fibre is clearly intended as a mere trimming or accessory rather than a structural component of the yarn or fabric. Importers rely on these guidelines to verify duty rates before cargo arrival.
