Green Tea Extract Bulk Supplier Questionnaire

Preparing a green tea extract bulk supplier questionnaire? Align marker, assay method, COA, samples, MOQ and document requirements first.

Requirements

This B2B sourcing guide helps buyers prepare a focused supplier review before requesting samples or quotation. The L-Theanine Green Tea Extract product page remains the main commercial page for ingredient identity, specification, sample support, packaging and RFQ details. This page supports long-tail research by organizing the questions buyers should confirm before comparing suppliers.

For faster review, send the target application, specification direction, expected quantity, destination market, sample request and document list in the first message. That lets the supplier match the discussion to a practical grade instead of a generic material name.

Selection Criteria

Review point	What to confirm	Why it matters
Marker target	L-Theanine, tea polyphenols, catechins or EGCG direction.	Different markers need different review paths.
Assay method	HPLC, UV or buyer-specified method.	Method wording affects COA and specification comparison.
Document package	Specification, representative COA, method notes and questionnaire fields.	Supports QA and sourcing review.
Application	Capsule, tablet, powder blend, beverage or food project.	Application affects physical and document priorities.
Commercial details	MOQ, sample quantity, packing, destination and lead time.	These inputs connect qualification with quotation.

Practical Recommendation

Use the supplier page for quotation and this guide for pre-RFQ preparation. If the project is still open, start with the application and sample testing path. If the specification is already fixed, send the target assay, method, particle size, document list, packaging size and destination market.

Sample Request vs Bulk RFQ

Dimension	Sample request	Bulk RFQ
Main purpose	Grade screening and document review.	Commercial supply planning after approval.
