Clarificatory tax amendment interpretation brings rock phosphate within exempt fertiliser entry, while other products need fresh factual inquiry.

Rock phosphate was treated as falling within "chemical fertilisers including bone-meal" under item 54 of the Kerala General Sales Tax Act because the later amendment expressly naming rock phosphate was regarded as clarificatory of the original entry; the exemption therefore applied on the facts found. For the other products sold as ultrafos, dolomite, peramphos, azo and thomas phosphate, the record did not establish their true composition or whether they were chemically processed fertilisers. Those classifications depended on evidence, so the finding was set aside and the matter remanded for fresh determination.

Issues: (i) whether rock phosphate fell within the description "chemical fertilisers including bone-meal" in item 54 of the First Schedule to the Kerala General Sales Tax Act and was therefore exempt from tax on the facts found; (ii) whether the other fertilisers sold under the names ultrafos, dolomite, peramphos, azo and thomas phosphate were chemical fertilisers covered by item 54.

Issue (i): whether rock phosphate fell within the description "chemical fertilisers including bone-meal" in item 54 of the First Schedule to the Kerala General Sales Tax Act and was therefore exempt from tax on the facts found.

Analysis: The earlier decision relied on by the Tribunal did not conclusively decide the character of rock phosphate, because the point was not actually in issue there. However, the amended schedule introduced by section 22 of the Kerala General Sales Tax (Amendment) Act, 1978 expressly included rock phosphate among the specified fertilisers, and the legislative change was treated as a clarification of the original description rather than a new subject-matter. That showed that rock phosphate had always been intended to be included within item 54. Since the sales were not first sales within the State, the exemption consequence followed.

Conclusion: Rock phosphate was held to be a chemical fertiliser under item 54, and the assessee succeeded on that issue.

Issue (ii): whether the other fertilisers sold under the names ultrafos, dolomite, peramphos, azo and thomas phosphate were chemical fertilisers covered by item 54.

Analysis: The Tribunal had treated these goods as merely similar items without examining the record or taking evidence on their true composition and mode of manufacture. The available material did not establish whether they were only different names for rock phosphate or products obtained by chemical processing. That question required factual investigation and an opportunity to both sides to adduce evidence.

Conclusion: The finding on these other fertilisers was set aside and the matter was remanded for fresh determination.

Final Conclusion: The exemption finding on rock phosphate was affirmed, but the controversy regarding the remaining fertilisers was sent back for de novo consideration.

Ratio Decidendi: Where a later amendment to a sales tax schedule clearly shows that a commodity was always intended to fall within a scheduled description, that amendment may be treated as clarificatory for interpreting the earlier entry; unresolved factual questions on the identity and composition of other goods require fresh adjudication on evidence.
