Citric Acid for Industrial and Specialty Formulations
Citric Acid Citric Acid is an organic acid used as an acidifier, pH buffer, chelating agent, cleaning auxiliary, and industrial formulation ingredient, with grade selection based on assay and impurity limits.
This page keeps the original product specification values and adds buyer-focused structure for sourcing, formulation testing, documentation, packaging, and export communication.
Use the values below as the original page specification reference, then confirm current TDS, COA, SDS, batch data, and application test results before purchase.

FAQ
Are the specification values original?
Yes. The Main Specification section keeps the original page values and presents them in a cleaner buyer-ready format.
Should buyers rely only on the page specification?
No. Buyers should confirm the latest TDS, COA, SDS, sample result, destination-market compliance, and contract specification before order.
Can China Lignin support samples and export documents?
Samples, TDS, COA, SDS, packing information, and export quotation can be prepared after the buyer confirms target application, required specification, destination market, and volume.
