Amino acid chelated mn

When sourcing Amino Acid Chelated Mn, you must prioritize the Manganese (Mn) content, typically ranging from 10% to 15%, and the total amino acid content (≥25-30%). Ensure the product has high water solubility (100%) and a stable pH value (4.0-7.0) to ensure compatibility with other fertilizers. The chelation rate is the most critical factor; look for suppliers who can provide evidence of a complete chelation process, which prevents the Mn ions from being fixed by the soil or reacting with phosphates.

For B2B buyers, it is essential to verify that the supplier complies with ISO 9001 for quality management. If the product is intended for organic farming, look for OMRI (Organic Materials Review Institute) or REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) compliance for the EU market. Always request a Certificate of Analysis (COA) and a Material Safety Data Sheet (MSDS) to ensure the product meets the heavy metal limits (such as Lead, Arsenic, and Cadmium) required by your local agricultural department.

Amino Acid Chelated Mn is primarily used as a foliar spray or fertigation agent to correct manganese deficiencies in crops like citrus, cereals, and legumes. Its functional advantage lies in the amino acid carrier, which allows for faster absorption through the leaf cuticle compared to inorganic salts like Manganese Sulfate. This results in enhanced photosynthesis, improved enzyme activation, and better stress resistance for the plants.

While the unit price of chelates is higher than inorganic sulfates, the utilization rate is 3-5 times higher. Buyers should calculate the cost per effective absorption unit. Because chelates are more efficient, you require lower application dosages, which reduces logistics and storage costs. For large-scale distributors, sourcing concentrated powder forms is more economically feasible than liquid forms due to significantly lower shipping costs per active ingredient.

The primary risks include product degradation during transit due to moisture and customs clearance delays caused by improper labeling. To mitigate this, ensure the supplier uses moisture-proof, multi-layer PE/PP bags or vacuum packaging. Furthermore, verify that the HS Code (typically 292249 or 310590) is correctly declared to avoid fines or seizures by customs authorities.

Start by requesting a small sample (1-2kg) for lab testing before committing to a bulk order. Negotiate based on volume tiers; for example, a 10-ton order should yield a 5-10% discount compared to a 1-ton order. Use Made-in-China.com's Secured Trading Service to ensure that payment is only released after the Third-Party Inspection (such as SGS or BV) confirms the Mn content and purity levels.

Since this is a non-hazardous chemical powder, Sea Freight (FCL or LCL) is the most cost-effective method for bulk orders. For urgent replenishment, Air Freight is viable but expensive. Ensure the supplier provides a Non-Hazardous Goods Declaration to streamline the shipping process. If shipping to regions with high humidity, insist on palletization with shrink-wrap to prevent caking during long-term sea transit.

Prioritize Audited Suppliers on Made-in-China.com who have undergone on-site factory inspections. Review their export history and check for third-party audit reports available on their profile. Always use Escrow-based payment methods and define clear quality claim clauses in the contract, specifying that the supplier is responsible for replacement if the Mn content deviates by more than 0.5% from the agreed specifications.
