EGCG Buyer Path
Use EGCG 98% When the RFQ Needs a High-Purity Catechin Specification
EGCG 98% is not the same sourcing question as general Green Tea Extract or Instant Green Tea Powder. Buyers should confirm purity target, assay method, COA data, particle size, sample behavior and document support before comparing price.

EGCG 98% vs Green Tea Extract, L-Theanine and Instant Green Tea Powder
Buyers often reach EGCG 98% after comparing several green tea ingredient pages.

Application Fit and Sample Testing
Common commercial applications for this ingredient include RTD tea, iced tea systems, milk tea powders, foodservice drink mixes. Before approval, buyers should test the sample in the real formula or process instead of relying only on a name match. Color, taste, solubility, particle size, carrier selection and packing format can affect production handling and finished-product consistency.
- Define the target assay, extract ratio or physical specification needed by the project.
- Share the finished-product format so HERBSEA can recommend a practical sample direction.
- Review COA data, microbiology, heavy metals, moisture and packing information before purchase approval.
- Keep sample labels, batch numbers, quotation notes and document files together for reorder review.
Batch Consistency and Documentation
For repeat purchasing, the approved sample should connect clearly with the commercial batch. Procurement teams can keep a simple record that includes supplier item name, batch number, specification version, COA file, packing photo, sample feedback and final quotation. This makes reorder checks easier and helps the buyer confirm whether a later batch follows the same sourcing brief.
If your project has a custom requirement, share it before sample dispatch. HERBSEA can review whether the requested document set, packing format, label wording, shipment timing and sample quantity are practical for the selected instant tea powder specification.
