Before You Request a Quote or Documents

Use this checklist to prepare a focused laboratory or B2B inquiry. It supports procurement review and does not replace your own technical, safety or supplier qualification process.

1. Identify the material. Include the product name, CAS number, required grade and intended research use.
2. State the specification. Share your required purity, analytical method and reporting basis. A product specification is not a result for the batch you may receive.
3. Name the documents you need. Ask for the applicable batch COA and specification. A formal SDS has not been issued for the listed Cytisine and Tetrandrine products; discuss professional review and destination requirements.
4. Give quantity and destination. Include units and country or region for a quote. Quantity is optional for document-only or technical requests.
5. Confirm order-specific terms. Current stock, proposed batch release, final price, dispatch timing, shipping and responsibility for taxes or duties are confirmed in the quotation.

Start with the relevant product specification, then use its quote or document request to keep the product and CAS number selected.
