Lithium Sulphate Manufacturer in India: Buyer Checklist for Quality, Documentation and Bulk Supply

A good lithium sulphate manufacturer in India will name the grade on the quote, send a batch-specific COA with the sample, and pack for export without being asked twice. If any of those needs chasing, that's your answer. Price can wait.

Grade first, then the price

Lithium sulphate, Li₂SO₄, has CAS number 10377-48-7 and a molecular weight of 109.94 g/mol. It's sold as battery, industrial and laboratory grade, and the three are not interchangeable. A ceramics line can often run on industrial grade at around 98% purity. A battery materials team usually can't, and it will want impurity limits for sodium, calcium, iron and chloride written into the specification.

So ask one plain question: which grade does this price cover? Quotes sometimes skip that detail, and the cheapest number on the sheet turns out to belong to the lowest grade.

Read the spec sheet line by line

Every lithium sulphate supplier should be able to put its specification in a table like this one. The figures below are the ones listed on the Vrik Pharma product page.

Parameter	Listed specification
Product name	Lithium Sulphate
CAS number	10377-48-7
Chemical formula	Li₂SO₄
Molecular weight	109.94 g/mol
Grade	Battery, industrial or laboratory
Appearance	White crystalline powder
Lithium content	Min 36%
Assay	Min 98%
Solubility	Soluble in water
Packaging	25 kg HDPE bags, fibre drums, customised bulk
Shelf life	Up to 2 years under recommended storage
Minimum order quantity	500 kg

Now compare that against what other quotes say. Same grade? Same assay floor? A lithium sulphate manufacturer that hedges on any of these lines should explain why, in writing.

Paperwork that should arrive before the container does

There are four main documents you will need for exporting most orders. These are the COA, MSDS, packing list and commercial invoice. Ensure your COA matches the batch you are purchasing. The MSDS is very important on your own shop floor as it is an irritant to the eyes and skin. It should also be kept in a sealed environment, cool and dry.

The MSDS often becomes an issue when your cargo is at the port. The customs do not wait. Any manufacturer of lithium sulphate will be able to provide you with all 4 on request. Request samples as early as possible.

Item	What to confirm before you order
COA	Issued per batch, with the test method named
MSDS	Current version, supplied with every shipment
Packing list	Bag or drum count matches the invoice
Commercial invoice	Product name and grade match the purchase order
Packing	Moisture-resistant, suitable for sea freight
Manufacturing date	Printed on every bag, so the 2-year shelf life can be tracked

Manufacturer, trader or exporter: pick for the order you have

My view: for repeat bulk orders, buy from the plant. When the producer controls the process, specification drift gets fixed at the source instead of passing through two middlemen. A trader is fine for a one-off 500 kg trial. A lithium sulphate exporter with its own factory covers both cases, as long as you can verify it.

Ask for the plant address and the ISO certificate. Ask whether a video walk-through of the packing area is possible. Real plants say yes.

Questions worth asking before a trial order

How many batches can you do with the same spec? What is the lead time for 500kg and at 5 tonnes? Is it sea-going or just road? Short questions, but slow answers can give you lots of information.
