Magnesium Sulphate Heptahydrate Price in India: CAS 10034-99-8 Complete Buyer's Guide

Magnesium sulphate heptahydrate sits at an interesting intersection in the Indian market — it's used everywhere from agriculture to pharmaceuticals to food and beverage fortification, and each segment has its own pricing norms. Buyers sourcing it specifically for food-grade applications often find themselves comparing quotes that aren't actually comparable, simply because they span different grades and end uses. 

This guide explains what shapes Magnesium Sulphate Price In India, and how to use the CAS number 10034-99-8 correctly when verifying product quality. 

Why Cross-Industry Demand Complicates Pricing 

Because magnesium sulphate heptahydrate serves agriculture (as a fertilizer additive), pharmaceuticals, cosmetics, and food and beverage fortification, the market has a wide spread of grades and price points all listed under the same general product name. A buyer sourcing for food-grade beverage fortification, as we discussed in our earlier post on magnesium sulphate heptahydrate for beverage fortification, needs to be specific about grade requirements to avoid comparing mismatched quotes. 

What Actually Drives Magnesium Sulphate Heptahydrate Price 

Key factors that influence pricing include: 

• Grade and certification – food-grade material with FSSAI documentation costs more than agricultural or technical grade 
• Order volume – bulk orders typically secure meaningfully better per-kilo pricing 
• Purity and solubility specification – tighter quality control adds to manufacturing cost but improves formulation performance 
• Packaging format – bulk bags and moisture-controlled packaging affect final landed cost 
• Seasonal agricultural demand – since a large share of magnesium sulphate demand comes from agriculture, seasonal fertilizer demand can influence overall market pricing even for food-grade buyers 

That last point is worth noting — food-grade buyers sometimes see price fluctuations tied to agricultural demand cycles, even though their own use case is unrelated to fertilizer applications. 

Using CAS 10034-99-8 Correctly When Comparing Quotes 

The CAS number 10034-99-8 confirms the chemical identity of magnesium sulphate heptahydrate, but it appears across every grade — agricultural, technical, and food grade alike. When comparing supplier quotes referencing this CAS number, always pair it with: 

• Explicit grade confirmation in writing 
• A batch-specific Certificate of Analysis 
• FSSAI or equivalent food-safety documentation, if sourcing for food or beverage use 

Relying on the CAS number alone to validate a quote is one of the more common sourcing mistakes buyers make with this particular ingredient, given how widely it's used across unrelated industries. 

Food Grade vs Agricultural Grade Pricing Gap 

The price difference between food-grade and agricultural-grade magnesium sulphate heptahydrate can be substantial, and it's not simply markup — it reflects genuinely different manufacturing and testing processes. Agricultural-grade material isn't tested for the impurity thresholds required in food applications, which is exactly why it's priced lower. Buyers should treat any quote significantly below market average as a signal to verify grade explicitly before proceeding. 

What to Verify Before Placing a Bulk Order 

Before finalizing a purchase, confirm: 

• The supplier explicitly certifies the product as food grade, with supporting documentation 
• A Certificate of Analysis is available for the specific batch being quoted 
• Solubility and purity specifications match your formulation requirements 
• The supplier can support your required order volume with consistent lead times 

Questions to Ask Your Supplier 

A short qualification conversation can prevent costly grade mismatches: 

• Is this magnesium sulphate heptahydrate certified as food grade, with documentation available? 
• Can you confirm the purity specification and provide a Certificate of Analysis? 
• How does your pricing compare across food-grade versus agricultural-grade product lines? 
• What is your typical lead time for bulk food-grade orders? 
• Can you support recurring monthly orders at a stable price? 

Getting Fair, Consistent Value 

Because magnesium sulphate heptahydrate spans so many different industries, getting fair value means being explicit about grade requirements from the very first conversation with a supplier — not assuming that a quote referencing the right CAS number automatically means the right grade.

FAQs 

1. Why does magnesium sulphate heptahydrate pricing vary so much across suppliers?  

Because the same compound is used across agriculture, pharmaceuticals, and food applications, each with different grade and purity requirements that directly affect price. 

2. Does the CAS number alone confirm food-grade quality?  

No — CAS 10034-99-8 identifies the chemical compound across all grades. Food-grade status needs to be confirmed separately through certification and documentation. 

3. Can agricultural-grade magnesium sulphate be used in food or beverage fortification?  

No — it isn't tested to the impurity thresholds required for food-safety compliance and shouldn't be used in food applications. 

4. Does seasonal demand affect magnesium sulphate pricing?  

It can — since a significant portion of demand comes from agricultural fertilizer use, seasonal fluctuations in that sector can influence broader market pricing. 

5. What documentation should accompany a food-grade magnesium sulphate order?  

A Certificate of Analysis for the specific batch, along with explicit food-grade certification and FSSAI or equivalent compliance documentation.
