How can someone structure half of their deposits? Do they just withdraw sometime under or at $10,000 and sometimes over $10,000 - that is not structuring. It may very well represent their specific cash needs for that period.
I agree with this. We bank several recyclers. A couple of them regularly exceed the CTR threshold, but also have some days where their cash needs are below the threshold.
Whether or not $190k per month is an appropriate volume for your customer is something you will need to determine through your EDD process. Factors such as the size of your customer's operation, and the proximity of competing scrapyards may reveal that this volume is appropriate, so you'll want to include these considerations in your EDD.
