Microbial cultures used for plant growth are classifiable as cultures of micro-organisms, not plant-growth regulators.

Cultures of micro-organisms mixed with talc powder and used to aid plant growth and improve crop health were treated as classifiable under heading 3002 as cultures of micro-organisms. Heading 3808 was considered to cover chemical products such as herbicides, anti-sprouting products and plant-growth regulators, but not living beneficial microbial cultures used to improve soil and root-zone conditions. Relying on the earlier decision and the HSN explanatory notes, the classification was upheld under heading 3002, with the Department's challenge rejected.

Issues: Whether the impugned bio-products, being cultures of micro-organisms mixed with talc powder and used for aiding plant growth and crop health, were classifiable under heading 3808 as plant-growth regulators or under heading 3002 as cultures of micro-organisms.

Analysis: The products were found to be living beneficial microbial cultures used to improve soil/root-zone conditions and to aid plant growth by increasing beneficial micro-organisms in the soil. Heading 3808 was held to cover chemical products such as herbicides, anti-sprouting products and plant-growth regulators, whereas heading 3002 specifically covered cultures of micro-organisms (excluding yeasts). The reasoning in the earlier decision dealing with similar microbial products was applied, and the HSN explanatory notes were relied upon to hold that cultures of micro-organisms used for technical purposes, including aiding plant growth, fall within heading 3002.

Conclusion: The impugned goods were classifiable under heading 3002 and not under heading 3808.

Final Conclusion: The Department's challenge failed, and the assessee's classification was upheld.

Ratio Decidendi: Cultures of micro-organisms used for aiding plant growth and maintaining crop health are classifiable under heading 3002 as cultures of micro-organisms, and not under heading 3808 as plant-growth regulators.
