Artificial Staple Fibers, Processed for Spinning

Customs authorities may request a manufacturer's technical specification or process certificate confirming that the fiber has undergone carding, combing, or an equivalent mechanical opening process. A fiber test report showing fiber alignment and the absence of entanglement typical of raw bale fiber can also support the classification. Working with a licensed customs broker familiar with textile fiber classifications is advisable when the processing state is not immediately evident from the commercial invoice.

Yes — lyocell, marketed under brand names such as Tencel, is an artificial cellulosic fiber and, when carded or combed for spinning, falls within the artificial staple fiber processed-for-spinning category. Its classification is based on fiber type and processing state, not brand name, so importers should ensure commercial documents reference the generic fiber type (lyocell) alongside any brand designation.
