COA
Batch number, assay result, test method, production date and contaminant scope.
Quality & Documentation Center
Documents buyers need before they trust a bulk quote.
HerbalSourcing screens COA, assay method, HPLC / UV availability, MSDS, TDS and market-specific document requirements before quotation.
COA
HPLC / UV
MSDS / TDS
Heavy metal / microbiology
Document Scope
What each RFQ can ask us to verify.
We separate document availability from confirmed compliance. If a batch document is not available yet, the RFQ response should clearly mark it as pending confirmation.
HPLC / UV report
Marker verification for standardized extracts such as Curcumin, Ginseng or Green Tea.
MSDS
Safety handling, storage, hazard and shipping review before export.
TDS
Specification, appearance, solubility, packing and application guidance.
Source statement
Botanical source, plant part and extraction route when required.
Compliance notes
Heavy metals, microbiology, pesticide residue and residual solvent checks by market.
Review Workflow
Quality review is part of the RFQ process, not an afterthought.
This process helps buyers compare suppliers on document readiness, not only unit price.
01Confirm product, active marker and assay method
02Request batch COA and available HPLC / UV support
03Screen heavy metal, microbiology and residual solvent scope
04Match document requirements to target market
05Confirm sample, pilot or bulk packing route
06Attach document status to the RFQ response
Batch Traceability
Batch records and destination-market needs are checked before a serious quote.
A serious ingredient RFQ should not stop at the SKU name. For B2B buyers, the RFQ must show the test method, available batch files, supplier-route boundary and target-market document status.
Batch identity
Lot code, batch number and production window
The RFQ response should state whether batch identity, production date, shelf life, storage condition and pack-label information are available, pending or not applicable.
Source route
Botanical, animal or synthesis route record
Product source, plant part or animal source, extraction or processing route and supplier-route documents are confirmed against the target grade and available batch.
Testing record
Assay method and contaminant scope
COA, HPLC or UV method, activity method, heavy metals, microbiology, residual solvent, pesticide residue or impurity scope are reviewed by product route.
Target market
Destination-market document confirmation
US, EU, India and Southeast Asia buyers may require different source, allergen, BSE/TSE, label-support or import-review documents, so compliance scope is never assumed from a generic COA.
Quote boundary
Available, pending and not applicable status
Sample, pilot and bulk quotations should separate confirmed files from pending supplier-route checks before a formal PI or payment step.
US Buyer Traceability Note
Prepare traceability records early for US-bound food or supplement ingredient RFQs.
The FDA FSMA food traceability rule page states that the original compliance date was January 20, 2026 and that FDA intends to extend the compliance date by 30 months to July 20, 2028. For US buyers, HerbalSourcing treats traceability lot code, batch identity, supplier-route records and testing files as RFQ questions to confirm before sample, pilot or bulk quotation.
FDA FSMA traceability rule reference01Destination country and buyer application: food, supplement, cosmetic, distributor, pharma-adjacent or intermediate use
02Traceability lot code or batch identifier when the destination market or buyer quality system requires it
03COA fields: batch number, assay result, test method, production date, shelf life and contaminant checks
04Supplier-route support: source statement, extraction or processing route, allergen position and BSE/TSE support when relevant
05Document status in the RFQ response: available, pending supplier confirmation, not applicable or private until PI/order stage

Send product, quantity and document needs first.
The fastest path is to send product name, specification, quantity, market and required files. We then mark available, pending and not applicable documents in the RFQ response.
