Plain-language overview

Use HS-6 310551 when shipping mineral or chemical fertilizers that contain nitrates and phosphates, especially in packages weighing up to 10 kg. For example, a shipment of 5 kg bags of a fertilizer blend for agricultural use would fall under this code.

This code is specific to fertilizers that include both nitrates and phosphates, distinguishing it from HS-6 310520, which covers only fertilizers with phosphates. If your product contains only nitrates, you would use HS-6 310530 instead.

When classifying your product, ensure that it meets the criteria of containing both nitrates and phosphates. If it’s a mixed fertilizer, check the composition to confirm it aligns with this HS-6 description.

Understanding the differences between these codes helps prevent misclassification, which can lead to delays or penalties during customs clearance.
