A buyer can share non-confidential application information such as:

• Intended product category or general application
• Required nicotine grade, purity, or concentration range
• Target quality specifications
• Required physical form and packaging
• Expected order volume and MOQ
• Storage and handling requirements
• Regulatory or market requirements
• Testing and documentation requirements
• Delivery destination and expected timeline

This gives the supplier enough context to recommend suitable materials without disclosing proprietary formulations, exact ingredient ratios, or other confidential process details.
