Essential character controls tariff classification of nutrient-based products, placing seaweed extract formulations under fertilizers, not growth regulators.

Classification depended on the products' essential character, composition and trade understanding. Zymegold Plus and Dripzyme contained seaweed extract and other nutrients, so they were treated as nutrient-bearing fertilizers under Chapter 31 rather than plant growth regulators under Chapter 38. The presence of micronutrients did not alter that essential character, and the department produced no contrary evidence to displace the appellant's classification claim. The earlier decision in the appellant's own case for the prior period reinforced the same view. On that basis, the products were held classifiable as fertilizers, and the duty demand and penalty could not be sustained.

Issues: Whether Zymegold Plus and Dripzyme were classifiable as plant growth regulators under Chapter 38 or as fertilizers under Chapter 31.

Analysis: The products were examined on their composition, dominant constituents, and how they are understood in trade and use. The reasoning proceeded on the distinction that fertilizers supply nutrients necessary for plant development, while plant growth regulators are organic compounds other than nutrients that alter physiological growth processes in low concentration. The products contained seaweed extract and other nutrients, and the material on record supported their use as nutrient-bearing fertilizers rather than growth regulators. The presence of micronutrients did not change their essential character. The earlier decision in the appellant's own case for the prior period, together with the trade understanding and the lack of contrary evidence from the department, supported classification under Chapter 31.

Conclusion: The products were not plant growth regulators and were correctly classifiable as fertilizers under Chapter 31.

Final Conclusion: The duty demand and penalty could not be sustained, and the appellants were entitled to relief on classification.

Ratio Decidendi: For classification, the product's essential character, composition, and trade understanding prevail, and a nutrient-based product containing seaweed extract and micronutrients is not a plant growth regulator merely because it may incidentally affect plant growth.
