Tariff Classification
An international customs nomenclature subclass designates scutched flax that has undergone mechanical separation from the woody shive but remains unhackled. Under this global classification, hs code 530121 governs the import and export of broken or scutched bast fibers of flax. The category excludes both raw retted straw and highly refined, combed long fibers.
Commercial Traceability
Customs documentation must record this six-digit number to determine the applicable tariffs and trade quotas when bulk shipments move from European processors to Chinese spinning mills. Invoices and bills of lading use hs code 530121 to declare the fiber type, verifying that the shipment contains scutched tow or long line scutched flax before any further combing or alignment has occurred. This specific classification provides the baseline for country-of-origin tracking and ensures that the material meets the raw-material standard required for spinning preparatory stages.
The classification is verified by inspectors at the port of entry who compare the declared code against physical samples taken from the bales to check the alignment and cleanliness of the fibers.
Processing Boundary
Spinning mills purchase scutched flax under this tariff heading with the expectation of executing their own combed preparation. Once the fibers are hackled on the mill’s own machinery, they transition to a different tariff subclass, as they are no longer scutched flax. This border marks the end of raw material trading and begins the yarn production cycle under hs code 530121.
