Quality system / release control

Quality is a release decision, not a certificate on a wall.

Every incoming lot is quarantined, sampled and tested before it is allocated. The certificate of analysis reports what the bench measured on that batch, against the limits agreed for the application.

Batch-specific, signed, with method and limit columns.

Retention

Sealed sample per dispatched lot, 12 months.

The release standard

A catalogue value is not a lot result.

Most product literature quotes a typical assay. That is useful for selection, but it does not tell a plant what is inside the drum that arrived on Tuesday. Our release decision is made on the actual lot, against the specification attached to the purchase order.

The bench tests the parameters that change process behaviour: assay, moisture, pH, insoluble matter, chloride, sulphate and iron. Solvent purity and water are run by gas chromatography. Food-grade phosphoric acid is screened to heavy-metal limits, including lead at a maximum of 2 ppm.

If a lot fails, it does not become a “slightly off” grade. It is quarantined, the customer is informed before dispatch, and a corrective action is opened with the source plant. The next released lot is allocated in its place.

01 Analytical scope

What gets tested, and how often.

The core panel applied to incoming and repacked lots. Additional tests are added for food-grade, solvent and customer-specific specifications.

Parameter Method Frequency Why it matters
Assay / purity Titrimetric or potentiometric Every lot Released against the customer-approved specification, not a catalogue typical.
Moisture Karl Fischer coulometry Every lot Critical for deliquescent salts and low-water solvents.
pH Aqueous solution, calibrated meter Every lot Recorded at the specified dilution and temperature.
Insoluble matter Gravimetric filtration Every lot Protects downstream filtration and catalyst beds.
Chloride & sulphate Turbidimetric / ion chromatography Every lot Tight limits for agrochemical and plating customers.
Iron & heavy metals Colorimetric / AAS / ICP-MS Every lot; ICP-MS for food grade Food-grade phosphoric acid held to max. 2 ppm lead.
Solvent purity Gas chromatography (GC) Every solvent lot Purity and water reported on the batch COA.
Appearance & odour Visual, reference standard Every lot Colour, clarity and foreign-matter check before packing.

Methods are referenced to BIS, ASTM, ISO or the customer-approved in-house procedure. Calibration records are available during audits.

03 Release workflow

Five gates between a tanker and a customer.

A lot can be rejected at any gate. Release is a sequence of signed decisions, not a single lab result.

01

Sample

A representative sample is drawn from the incoming pack or tanker after homogenisation. The sample ID is written into the lot register before testing begins.

02

Test

Assay, moisture, pH, insoluble matter, chloride, sulphate and iron are run against the agreed specification. Solvent lots run by GC; food-grade acid runs to trace-metal limits.

03

Review

The analyst records the result and the QA lead compares it with the specification. Any out-of-limit result triggers quarantine and a supplier corrective-action request.

04

Release

A passed lot is released for allocation and repacking. The COA is generated against the actual batch number and signed off before the dispatch file is opened.

05

Retain

A sealed reference sample is stored for twelve months. The lot file — COA, SDS revision, invoice, packing list and weighbridge slip — stays searchable for audits.

04 Dispatch file

What travels with the consignment.

The document set is assembled before the truck is loaded. Missing paperwork holds the dispatch; it does not follow later.

Document control

SDS revisions are checked against the current register. COAs are signed and batch-linked. Export files are reviewed by the documentation desk before container sealing.

  • 01 Tax invoice with GSTIN and HSN code
  • 02 Batch-specific certificate of analysis
  • 03 Safety data sheet — current revision
  • 04 Packing list with net and gross weights
  • 05 Weighbridge slip from origin
  • 06 IMDG declaration and UN packing certificate (export)
  • 07 Certificate of origin (export, on request)
  • 08 Food-grade declaration (food-grade lines)
Quality questions

What buyers ask before an audit.

Release practice, custom specifications, repacking controls and non-conformance handling.

Speak with the QA desk
01 Is every consignment accompanied by a lot-specific COA?

Yes. The COA is generated against the actual lot number, not a generic product specification. It reports the tested assay, moisture, pH, insoluble matter, chloride, sulphate and iron values, along with the release date and analyst reference. A sealed retention sample is kept for twelve months.

02 Can you supply against a customer-specific specification?

For repeat annual contracts, yes. We review your specification against the source plant’s capability before quoting, then hold the agreed limits in the supply agreement. Trial lots are sampled and tested against your method before the first commercial dispatch.

03 Do you repack chemicals at Ankleshwar?

We repack dry alkalis and selected liquids from bulk into 25 kg bags, carboys and drums under a controlled procedure. Food-grade phosphoric acid is repacked only in the segregated food-grade bay. Solvents are handled in the flameproof bay with grounding and bonding.

04 What documentation is available for a vendor audit?

GST and IEC registration, GIDC allotment, GPCB consent, PESO licence, food-grade handling records, calibration certificates for the bench instruments, SDS revisions, retention sample log and the last internal audit report. We schedule audits by appointment so the QA lead is present.

05 How do you handle a non-conforming lot?

The lot is quarantined in a marked red-tag area, the customer is informed before dispatch or immediately on discovery, and a corrective action is opened with the source plant. Replacement material is allocated from the next released lot. The disposition is recorded in the lot file.

Audit & documentation

Ask for the lot file before you place the order.

We would rather answer the hard documentation questions during qualification than after the first dispatch. Request a sample COA, SDS revision or the vendor onboarding pack.
