Technical qualification
Buyers should first confirm whether 3N, 4N, or both grades fit the intended application. The next step is reviewing the brochure, relevant reference analysis report, and any buyer-specific impurity, D50, moisture, LOI, or packaging needs.
- Confirm 3N, 4N, or both grade interest.
- Review reference analysis reports in the right context.
- List required impurities, D50, moisture, LOI, and packaging items.
Commercial and documentation review
Before sample, quote, or trial order discussion, buyers should share company identity, destination country, application, end-use note, quantity, timeframe, and requested documents. This keeps commercial steps under manual review.
- Share application and destination country.
- Confirm sample, trial order, or bulk supply path.
- Discuss formal transaction documents separately from reference reports.
