BioThrive Bloom 0-5-4 NPK Fertilizer
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.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the fertilizer is not in retail packages and contains only two of the three elements
This heading covers other fertilizers containing at least one fertilizing element, but not all three, so it applies when the product does not meet the full NPK requirement.
If the product is in tablets or similar forms or in packages weighing not more than 10 kg
This alternative covers goods of chapter 31 in tablets or small retail packages, which may apply if the packaging format changes.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• 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
