I hope this message finds you well.

We are currently planning to use approximately 1 metric ton per month of Sodium Lignosulfonate 93% Brown Powder SF-1. Before proceeding further, we would appreciate it if you could confirm whether a sample of 500g can be provided for evaluation.(Can you provide a sample?)

Additionally, could you please send us your quotation based on CIF Busan (Incoterms 2020) conditions, including payment terms?

We look forward to your prompt response. Thank you in advance for your cooperation.

Best regards,
