A good understanding of chemical standards is essential to make an informed purchase decision. Chemicals are graded based on multiple measurements and standards. Knowing chemical grades helps avoid confusion when you are buying chemicals online or from a traditional vendor.
But, chemical grading is more than just a quality indicator. It is also a measure of the ease of procurement i.e the challenges that a chemical importer in India, or any other part of the world, must overcome to purchase high-quality chemicals.
How Are Chemicals Graded?
Chemicals are graded based on their composition. The greater the number of secondary components like other chemicals, metals, and water, the less is its grade. High grade is a mark of purity and also an indicator of procurement challenges.
What Are The Types of Grades? There are multiple grading standards but the most common ones that chemical buyers and suppliers encounter daily include:
Reagent
U.S.P
Laboratory
Practical
Technical
1. Reagent
Reagent chemicals are high purity chemicals and meet the standards set by the American Chemical Society. They are ideal for use in a research and development laboratory.
2. U.S.P.
U.S.P is an acronym for United States Pharmacopeia (USP). USP grade chemicals are chemicals with sufficient purity to be used for food, drug, or medicinal use. They can also be used for laboratory work.
3. Technical
All the chemicals used in an industrial environment are technical grade. Their quality is sufficiently high enough to be used in large scale commercial manufacturing. In terms of purity, they are much lower than Reagent and U.S.P grade chemicals. The reason for this is that technical grade chemicals contain a small number of other chemicals and impurities.
4. Laboratory
Laboratory grade chemicals have more or less the same applications as reagent grade chemicals. The only difference is that the former is not as pure as the latter. However, impurities in lab-grade chemicals are not excessive.
5. Practical Grade
In terms of purity, practical grade chemicals are lower-intermediate. They are not subjected to any specific standard tests but it is a given that practical grade chemicals contain an acceptable amount of impurities. They are widely used in the manufacturing industry.
How Chemical Buyers Must Buy Quality Chemicals?
Because chemicals are used in bulk during manufacturing, chemical buyers and traders must buy them from trusted sources. Considering the complex rungs in chemical logistics, a buyer can't be 100% assured about quality. But online b2b platforms for chemicals are helping overcome this challenge. At these platforms, you can easily find trusted companies, traders and manufacturers like BASF Ltd, A. B. Enterprises, and more. Chemical buyers can connect, engage, send quotations, negotiate and but quality chemicals using just their mobile or computer.
