To whom it may concern,

Thank you for your listing of High Quality 99% SR17018 (CAS *****-45-0).

My name is Ralph Boyd, an independent researcher based in the US. As stated in your FAQ, you offer free samples of 5-25g. I would greatly appreciate a 5g-25g free sample for evaluation in hobby lab research (research use only, not for human consumption).

Please provide a Certificate of Analysis (COA), confirmation if the sample is fully free (including shipping) or if any fees apply, secure/discreet packing details, and estimated delivery time under DDP to the provided address.

Please ensure labeling complies with research chemical import requirements.

If any payment is needed (e.g., for shipping), I prefer the Alibaba Trade Assurance option for added security.

If the quality meets my standards, I may be interested in future orders.

Best regards,

Ralph Boyd
