Plain-language overview
Use HS-6 310490 when importing or exporting potassic fertilizers that don't fit into specific categories. This code applies to products like potassium sulfate or potassium chloride used in agriculture to enhance soil fertility.
This code is distinct from HS-6 310420, which specifically covers potassium chloride in granular form. If your product is a different potassic fertilizer not clearly defined, 310490 is the right choice.
The 310490 line includes various potassic fertilizers that may come in different forms, such as powders or granules, and are used for soil enrichment. These fertilizers are essential for crops that require potassium for optimal growth.
When considering HS-6 310490, ensure your product is indeed a potassic fertilizer and not a mixed fertilizer, which would fall under a different heading. Proper classification helps avoid delays in customs clearance.
