What is Government Stamping and Why is it So Important?

Before we even address the topic of Government Stamping, we need to understand how important the weighing scale is, to maintain HONESTY in the system.

Say if you go to a local Kirana store and ask for One Kg of Dal. The shopkeeper needs to be sure that he is giving you at most 1 kg of dal if not less. On the other hand, you have to be sure that you are receiving 1 kg of Dal and not less. Now how will you tell that the dal is 1 kg exactly so that its not a loss for either of the parties. It is through a Weighing Scale (preferably a HSCo Branded one ;)). So the weighing scale actually makes sure that the shopkeeper remains Honest, and the customer is given what she has paid for.

Now let’s assume that the weighing scale is not accurate. In this case, it would either show the weight more than the actual weight (in which case the shopkeeper is benefiting) or shows less weight (in which case the customer is benefitting). Hence there is DISHONESTY in the system because the other person is not getting the full value of the transaction.

Here is where the Government comes in place – The Legal Metrology Department to be more specific. What the Government does is, it checks the weighing scale and if it is proper it would seal the scale. So if the scale has a Government seal, you can be sure that the scale is not tampered with. Moreover, the government also issues a certificate of authenticity with the details of the scale and the Legal Metrology Inspector who has verified the scale and in whose presence the scale has been stamped.

So let’s say a manufacturer like Hindustan Scale Company (HSCo) had made a weighing scale and it has passed all its rigorous internal testing. After the scale is checked by the QC team, a government challan is filled paying the requisite fees for the Government Stamping of the scale. A local inspector is assigned the task of verifying the weighing scale’s genuineness. The inspector would come to the factory, check the weighing scales and if the performance of the weighing scale is found to be satisfactory, it would issue a certificate in the name of HSCo saying that the scale is now fit to be used by the public and also put his seal on the weighing scale so it cannot be tampered with. This is true for an Electronic and Mechanical scale. So if the scale is certified by the Legal Metrology Department, then you can be sure that the scale is showing you the correct weight.

Now when Hindustan Scale Co – HSCo is selling and electronic scale to the local Kirana owner, three things would be given. The scale Itself, the Invoice and the ORIGINAL GOVERNMENT CERTIFICATE. The Government also mandates all shopkeepers to display the certificate wherever the scale is being used.

How to read a certificate that is issued by the Legal Metrology Department.

The legal Metrology Department has two types of certificates. One is for Digital Weighing scale that is individual for each scale. So it would have a serial number, other details, etc of a SINGLE WEIGHING SCALE. On the other hand the certificate for mechanical scale is in a lot. Example Hindustan Scale Company – HSCo has manufactured 100 pieces of 20 kg Weights. So HSCo will not be issued 100 certificates. It would be issued a single certificate having the quantity of 100 pcs of 20 kg Weights. The below Certificates would make it clear


Sample Stamping Certificate



Electronic Scale that we manufacture for 300 kgs.

  1. The bar Code that identifies the certificate
  2. Serial No: The serial number of the Certificate. This one will be carried forward in your next certificate once you Restamp your scale at the end of the Renewal cycle
  3. Date: The date when the certificate is issued
  4. Place: Place of stamping. This would be either the inspector’s office or the Manufacturers premises as mentioned in the Pt 5
  5. Manufacturer’s Name and Address.
  6. Inspector’s Name: The inspector who has verified the scale and putting his/her seal on the scale
  7. Receipt No: This is the receipt for the amount that the Manufacturer deposits in the Government Treasury
  8. GRN Number: This is the GRN number when the manufacturer fills the verification fees of the Scales online
  9. Details of the Weighing Scale that is being Verified:
    1. The maximum capacity of the weighing scale. In this scale we have verified a 100/200/300 kg scale.
    2. Make: Hindustan Scale – This is our own manufacture
    4. Class: This is a Class III scale which means that is a medium accuracy scale. Class II scales are high accuracy scales that are used in Jewellery and bullion industry. Class I scales are used for ultra high precision like diamonds and life saving drugs. There is also class IIII scales that are low accuracy scales. These are used for Coal, Hay, etc.
    5. This indicates that this certificate is valid for how many pieces. In this case the certificate is valid for one (1) piece
    6. This is the cost of stamping of the scale. In this case it is 400/-
  10. This is the total fees that Hindustan Scale has paid for this scale.
  11. Date before which the renewal has to be done: THIS IS AN IMPORTANT DATE. IF THE SCALE IS NOT RENEWED BEFORE THIS DATE YOU ARE LIABLE FOR UPTO A FINE OF 25,000/- OR MORE. For electronic scales its one year.
  12. This certificate can be used by the manufacture. In this case it is Hindustan Scale Company
  13. This is the digital signature of the verification inspector along with her division



Absolutely all the points are same as in the case of electronic certificate. The only differences are that in a mechanical scale certificate

  • In the point 9a and 9e there was only one scale. Here there are a lot of weights, one piece of 100 gm, 5 pieces of 20 kg CI Weight, etc. Hence Mechanical scales are verifies and the certificate is given in Lots.
  • Look at the Due Date: In this case when you compare the date of stamping and the date of restamping, the difference is two years. Hence always look at the due date to Restamp the scale.
  • You see, there is an additional charge of 185/- This is the on premise fees. That because the inspector has come to our premise and stamped the weights and hence taken an additional charge of 50% extra to cover his time and travelling expenses. So don’t be suspicious if there is an extra line in the expenses.
