Plain-language overview
Use HS-6 310540 when importing or exporting ammonium dihydrogenorthophosphate, commonly known as monoammonium phosphate (MAP). This fertilizer is often shipped in bags weighing 10 kg or less, suitable for agricultural use.
This code specifically addresses fertilizers that contain both nitrogen and phosphorus, distinguishing them from other fertilizers like those classified under HS-6 310520, which covers diammonium phosphate alone. Understanding these differences is key for accurate classification.
Ammonium dihydrogenorthophosphate is widely used in agriculture to promote plant growth, especially for crops requiring high phosphorus levels. If you're dealing with mixtures of MAP and diammonium phosphate, this HS-6 code applies.
When considering shipments, note that this fertilizer is typically packaged in small bags for retail distribution, making it convenient for farmers and gardeners. Ensure your invoices reflect the correct HS code to avoid customs issues.
