BioThrive Bloom 0-5-4 NPK Fertilizer from Mexico
BioThrive Bloom is a liquid fertilizer with an NPK ratio of 0-5-4, derived from bat guano and potassium sulfate, packaged in quart retail bottles. It is classified under tariff item 3105.20.00 because it contains all three fertilizing elements—nitrogen, phosphorus, and potassium—even though the nitrogen content is declared as zero. The retail packaging and inclusion of all three elements place it within the scope of mineral or chemical fertilizers containing nitrogen, phosphorus, and potassium.

Import Tips
• Ensure the product label clearly shows the NPK analysis and that it is not put up in tablets or packages over 10 kg, as that would shift classification
• Verify with the CBSA that the zero nitrogen declaration does not affect the tariff item, as the presence of all three elements is sufficient
• Keep commercial invoices and product specifications ready for customs review
