Specific tariff heading prevails for chain sprockets used in power transmission over broader residual classification

Imported chain sprockets were treated as classifiable under Chapter sub-heading 8483.40 because that entry specifically mentioned chain sprockets and was not excluded by its wording. The tariff description prevailed over the importer's broader claim under Chapter sub-heading 8431.49 read with 8429.59, since the sprocket was used for transmission of power and the specific entry was more apt than a general or residual heading. The HSN Explanatory Notes were regarded as supportive and consistent with the tariff text, and resort to other headings was considered unnecessary where a specific classification entry applied.

Issues: Whether the imported chain sprocket was classifiable under Chapter sub-heading 8431.49 read with 8429.59 as claimed by the importer, or under Chapter sub-heading 8483.40 as contended by the Revenue.

Analysis: The description under Chapter sub-heading 8483.40 specifically mentioned chain sprockets, and the Court found that they were not excluded by the wording of the heading. On the facts, the sprocket was used for transmission of power, and the specific tariff entry was held to prevail over the more general residual heading claimed by the importer. The Explanatory Notes to the HSN were treated as supportive of, and not inconsistent with, the tariff description. In the presence of a specific tariff description, reference to other headings or residuary entries was held to be unnecessary.

Conclusion: The imported chain sprocket was classifiable under Chapter sub-heading 8483.40 and not under Chapter sub-heading 8431.49 read with 8429.59.
