Glycerine Grades and COA: RFQ Checklist for Pharma, Food and Industrial Buyers

Refined vs industrial glycerine, USP/food-adjacent limits, glycerol content on COA and packing — before you sign an annual glycerine contract.

Supplying industrial chemicals from Vadodara since 2015 — ETP coagulants, RO programs, and process chemicals with batch COA/MSDS.

Glycerine (glycerol) grades split on purity, colour, and documentation — not on the word “glycerine” in the product title. Food, pharma-adjacent and cosmetic buyers need tight glycerol content and low impurities; industrial alkyd and resin plants may run refined industrial grade with COA matched to their internal spec, not automatically USP.

Drashti Chemicals quotes glycerine from Vadodara with batch COA. Name grade, min glycerol %, colour/APHA if relevant, pack (235 kg drum common), and end use on the RFQ — we do not publish list prices.

Refined vs industrial — what changes on the COA

Higher refined grades show higher glycerol assay, lower colour, and tighter limits on chloride, heavy metals or related parameters depending on manufacturer sheet.

Industrial glycerine may suit non-food resin and soap routes — using it on a food PO without grade alignment is an audit failure.

RFQ lines procurement should copy from QA

Min glycerol content %, grade name (refined/technical/USP if required), colour limit, monthly kg, drum vs IBC, delivery city, and attachment of last accepted COA when switching suppliers.

State whether material is vegetable-origin only if your label or export file requires it — not all COAs default to origin statement.

Packing, hygroscopy and storage

Glycerine is hygroscopic — keep drums sealed and bungs tight in monsoon warehouses. First-in-first-out avoids colour drift complaints on long storage.

Drum integrity matters for road freight to Surat, Ahmedabad and GIDC sites — note unloading equipment on the RFQ if tail-lift needed.

Pairing with formaldehyde routes on separate lines

Resin plants may buy glycerine and aldehyde sources in the same month — separate SKU documentation and EHS storage. See formaldehyde vs paraformaldehyde handling for aldehyde form on PO.

Consolidate glycerine with solvents or organic acids when grade and freight allow one Vadodara truck.

Frequently Asked Questions

Is all glycerine food-grade?

No — quote food or pharma limits explicitly on the RFQ if that is the end use.

What glycerol % is typical on COA?

Depends on grade — share your minimum assay on the PO so quotes match; do not compare vendors on unnamed “glycerine.”

Can glycerine freeze in winter transit?

Pure glycerine has high pour point relative to water — plan pumping heat if your store is unheated.

Does Drashti refine glycerine?

We are a Vadodara distributor with manufacturer COA — we match lot documentation to your PO.
