Whether a Company dealing in consumer goods and selling its products all over India should send such nominations of a Director to all 36 centres of Legal Metrology? (b) The Directors of large Company with huge turnover, in ordinary course, do not get involved in day to day compliance matter like Packaged Commodity Rules. It does not sound logical to held a Director responsible when he is not involved in the compliance.

What is the prevailing practice amongst large MNC operating in India? : Vasant Gori

Yes, the nomination has to be sent to all state Controllers where your products are sold. However, the nomination is optional. You can maintain the previous system. Anyway, it is not just the nominated director, the company along with any official whose connivance or negligence led to the violation of Rules, will be implicated. We do not see any good in nominating a director.

The individual sticker is prohibited for alteration but label is not prohibited for any alteration of discloser as required under Legal Metrology law in India.
Proviso of 6 (3) of The Legal Metrology (Packaged Commodities) Rules, 2011 instruct procedure about how to reduce price. It does not direct procedure for any other circumstances like increasing price or same price with other alteration relating to disclosure on package. In the light of above provisions, I think we can use label on pre-printed label for alteration: Nitesh

Under Rule 4, read with Rule 8(1), labels are principal display panel. Stickers are not labels; they are used to paste on a declaration to alter it, which is not permissible under R 6(3). Note the use of the word, "individual" in the Rule. So, altering a declaration by using a sticker on the MRP, for example, is not permissible.

Rule 18 permits charging higher prices proportional to increase of any tax only. In that case, two advertisements should be published (in case of central tax only) followed by circular to all dealers, Director and Controllers of States. But, use of any sticker is not suggested.
