Harmonized System Chief Weight Tariff Reclassification Driven by Moisture Regain Adjustments
Adjusting dry test mass using official moisture regain values shifts binary fiber ratios, changing chief weight tariffs and altering landed customs duties.
Harmonized System Note 2
Legal Classification
Statutory interpretation rules governing Section XI of the International Convention on the Harmonized Commodity Description and Coding System establish binding criteria for categorizing textile products containing mixed fibres. Tariff auditors apply Harmonized System Note 2 to resolve classification disputes when goods consist of two or more distinct textile materials. The note mandates classification based on the component that represents the highest weight percentage.
Its provisions govern raw fibres, yarns and woven fabrics, but cede authority when specific chapter notes override general mixture rules.
Blend Determination
Mass balance calculations dictate tariff headings for blended yarns and mixed-fibre woven fabrics. When evaluating a fabric containing cotton, polyester and wool, application of Harmonized System Note 2 requires identifying which single material predominates by weight. Equal weight proportions trigger tie-breaker provisions that assign the goods to the heading appearing last in numerical order.
Component Priority
Elastomeric yarns added for stretch properties frequently complicate tariff calculations despite low overall weight percentages. Even minor weight shifts can shift classification between different chapters under Harmonized System Note 2 rules. Importers verify laboratory blend composition reports to prevent incorrect duty rate assessments at customs entry points.
Custom Assessment
Chemical analysis methods under standardized ISO procedures confirm constituent mass percentages before entry declaration. Misinterpreting Harmonized System Note 2 leads to tariff misclassification, resulting in retroactive duty penalties or shipment clearance delays. Documentation accompanying commercial invoices must detail dry fibre mass ratios.
