How to Choose the Right Grade of Sodium Chloride for Your Application
When it comes to buying sodium chloride (NaCl) for industrial or laboratory use, not all grades are the same. Choosing the wrong grade could lead to product contamination, failed tests, or damage to equipment. That’s why it’s crucial to understand the different grades of sodium chloride available and match them with your intended application.
In this guide, we’ll break down the most common grades of sodium chloride and help you make the right choice.
Types of Sodium Chloride Grades
At Arch Industries, we supply high-purity sodium chloride in several standardized grades, each serving different purposes:
LR Grade (Laboratory Reagent)
- Purity: ≥99.5%
- Usage: Laboratory experiments, chemical analysis, biotech formulations
- Features: Very low impurities, consistent particle size
- ✅ Ideal for: Labs, research centers, universities, pharmaceutical testing
Pharmaceutical Grade
- Purity: 99.0%–99.9%
- Usage: IV saline, dialysis, oral rehydration salts
- Features: Complies with IP/BP/USP standards, highly refined
- ✅ Ideal for: Hospitals, pharma manufacturers, medical formulations
Industrial Grade Sodium Chloride
- Purity: 95%–98%
- Usage: Textile processing, dyeing, leather tanning, de-icing, water softening
- Features: Contains some impurities, optimized for cost-efficiency
- ✅ Ideal for: Large-scale industrial applications, water treatment plants
Food Grade (Optional Use Mention)
- Purity: 98%–99%
- Usage: Food seasoning, preservation
- Regulation: Often contains additives like iodine
Application vs. Grade – How to Choose?
| Industry | Recommended Grade | Key Requirements |
| Pharmaceuticals | Pharma Grade | IP/BP/USP standards, low heavy metals |
| Chemical Labs | LR Grade | High purity, consistent granule size |
| Water Treatment | Industrial Grade | Bulk quantity, non-reactive packaging |
| Textile & Dyes | Industrial Grade | Cost-effective, chloride balance |
| Food & FMCG | Food Grade | Iodized, additive-safe |
If you’re unsure which grade fits your use, it’s better to consult with a trusted sodium chloride supplier like Arch Industries.

Why the Right Grade Matters
Using the wrong grade can lead to:
- Failed QC testing in labs or pharma
- Residue buildup in industrial machinery
- Legal compliance issues in regulated sectors
- Product failure or contamination risks
That’s why we never recommend “one-size-fits-all” sourcing — especially in regulated industries.

FAQ – Frequently Asked Questions
Q1. What are the common grades of sodium chloride?
Ans – Sodium chloride is commonly available in LR (Laboratory Reagent), pharmaceutical, industrial, and food grades — each suited for specific applications based on purity and safety.
Q2. Which grade of sodium chloride is used in IV solutions?
Ans – Pharmaceutical-grade sodium chloride is used in IV solutions, oral rehydration salts, and dialysis fluids. It meets strict pharmacopeia standards.
Q3. Can industrial-grade sodium chloride be used in labs?
Ans – No, industrial-grade sodium chloride contains impurities and is not suitable for analytical or research purposes. Labs require LR-grade NaCl for accurate results.
Q4. How do I choose the right sodium chloride grade for my business?
Ans – Consult with your supplier, consider your industry regulations, and request a COA (Certificate of Analysis). Arch Industries helps buyers select the appropriate grade.
Q5. What is the difference between LR grade and pharma grade sodium chloride?
Ans – LR (Laboratory Reagent) grade sodium chloride is used in analytical chemistry and labs where purity and consistency are critical. Pharma-grade NaCl meets pharmacopeial standards (IP/BP/USP) and is used in injectable solutions, dialysis fluids, and ORS. The choice depends on regulatory needs and end-use.
Q6. Can I use food-grade sodium chloride in pharmaceutical or lab applications?
Ans – No. Food-grade salt often contains additives like iodine or anti-caking agents that are unsuitable for pharma or lab use. Always choose pharma-grade or LR-grade sodium chloride for regulated environments.
Q7. Does Arch Industries provide documentation like COA or MSDS with each grade?
Ans – Yes, Every batch of sodium chloride — whether LR, pharma, or industrial grade — is accompanied by a Certificate of Analysis (COA) and Material Safety Data Sheet (MSDS) to ensure traceability and quality assurance.
