FAQ
Q1: Can you provide COA for each shipment?
A1: Yes. COA can be provided for each batch, including Mn content and key impurity levels such as Fe, S, P and Se.
Q2: Do you support SGS / BV third-party inspection?
A2: Yes. SGS / BV inspection can be arranged before shipment upon buyer's request. Inspection scope, sampling method and cost should be confirmed before order placement.
Q3: Is this product directly used as battery cathode material?
A3: No. 99.7% EMM flakes are mainly supplied as a manganese raw material for producing EMD, manganese sulfate, manganese carbonate and other manganese-based compounds used in battery material processing.
Q4: What is the typical delivery time?
A4: For available stock, delivery is normally 7–10 days after order confirmation. For customized specifications or large-volume orders, the lead time is usually 15–30 days, subject to production schedule and final contract terms.
Q5: What packaging options are available?
A5: Packaging options include 50 kg bags, 500 kg steel drums, 1 MT jumbo bags, or customized packaging according to buyer requirements.
Q6: Can impurity limits such as Fe, P or Se be customized?
A6: Special impurity requirements can be discussed before order confirmation and shall be subject to production availability, COA results and mutually agreed specifications.
