Composition-based tariff classification and normal limitation apply to doubled or twisted yarn without suppression or misstatement.

Doubled or twisted yarn made from duty-paid spun yarns was treated as manufacture, but classification depended on the constituent fibres and the predominance test rather than a single uniform tariff treatment. Where non-cellulosic yarn predominated, the product fell under the specific tariff entry; where it did not, it fell under the residuary item. Duty already paid under the same tariff entry could be set off, and no further demand survived for varieties correctly classifiable under the residuary heading. On limitation, full disclosure in classification lists and departmental knowledge negatived suppression or wilful mis-statement, so the extended period was unavailable. Earlier demands were time-barred, and later demands could be enforced only within the normal limitation period.

Issues: (i) Whether doubled or twisted yarn manufactured from duty-paid spun yarns was classifiable under the residuary tariff item or under the specific tariff entries depending upon its composition, and whether duty already paid on the constituent yarns entitled the assessee to set-off in appropriate cases. (ii) Whether the differential duty demands were barred by limitation or were saved by the extended period on the ground of suppression or mis-statement.

Issue (i): Whether doubled or twisted yarn manufactured from duty-paid spun yarns was classifiable under the residuary tariff item or under the specific tariff entries depending upon its composition, and whether duty already paid on the constituent yarns entitled the assessee to set-off in appropriate cases.

Analysis: The process of doubling or twisting was treated as manufacture. However, the product could not be placed in one uniform class irrespective of composition. The correct tariff entry had to be determined on the basis of the constituent fibres and the predominance test. Where the constituent yarns of non-cellulosic origin predominated, the product fell under the relevant specific entry. Where the composition did not satisfy the specific entry, the yarn was classifiable under the residuary item. For the varieties found classifiable under the residuary item, duty had already been paid under that heading and no further demand could stand. Where classification fell under the specific entry, the demand could survive only to that extent, and set-off was allowable for duty already paid on the constituent yarns under the same tariff entry.

Conclusion: The classification was upheld only in part. Some varieties were held classifiable under the residuary item and not exigible to further duty, while the 50:50 polyester/acrylic variety was held classifiable under the specific entry. Set-off was available where duty had already been paid under the same tariff entry.

Issue (ii): Whether the differential duty demands were barred by limitation or were saved by the extended period on the ground of suppression or mis-statement.

Analysis: The assessee had filed classification lists with full particulars of composition and had been clearing the goods under the declared classification with departmental knowledge. The record did not support suppression or wilful mis-statement. The case was treated as one of short levy arising from error or mis-construction, so the extended period was not available. For the demand linked to the later reclassification notice, the entire demand relating to the earlier period was time-barred. For the later notice, only the normal period could be enforced.

Conclusion: The extended period was not available. The earlier demand was time-barred in full, and the later demand survived only within the normal limitation period.

Final Conclusion: The appeals succeeded substantially in respect of the varieties falling under the residuary item and on limitation, but the demand survived only for the specific variety held classifiable under the relevant tariff entry and only within the permissible period.

Ratio Decidendi: Doubled or twisted yarn is to be classified by applying the composition-based predominance test, and where the record shows no suppression or mis-statement, the normal period of limitation alone applies.
