EGCG 98 Powder Supplier Guide

Comparing EGCG 98 powder suppliers? Confirm assay method, COA, sample lot, packing, MOQ and RFQ details before qualification.

Requirements

This B2B guide helps purchasing, QA and product development teams prepare supplier questions before samples or quotation. Use the EGCG 98% product page as the main commercial page, then confirm specification, COA, sample, packing and destination details with the supplier.

Selection Criteria

Review point	Buyer input	Why it matters
Assay direction	EGCG assay target, HPLC wording and sample lot reference.	Keeps supplier values tied to the buyer specification.
Physical fields	Appearance, color, odor, particle size and flow direction.	Supports sample handling and formulation screening.
Document set	Specification sheet, representative COA, method note and packing information.	Documents support QA before sample approval.
Sample plan	Sample quantity, test matrix and destination address.	Clear sample inputs reduce supplier back-and-forth.
Commercial path	MOQ expectation, packing size, lead time and destination market.	Commercial details prepare the next quotation step.

Practical Recommendation

Use this guide as a pre-RFQ worksheet. If the specification is fixed, send the target assay, powder behavior and document list first. If the grade is still open, ask for available specification options with representative COA and sample lot details.

Sample Review vs Bulk RFQ

Dimension	Sample review	Bulk RFQ

Buyer input	Application, sample quantity, target specification and COA needs.	Quantity, MOQ expectation, packing size and destination market.
