Sh.Srikanthan S Ji, Sir,
When any manufacturer purchases goods from a Vendor ( Vendor means a person or company offering something for sale, especially a trader in the street, retailer,seller,dealer,trader,shopkeeper,hawker,supplier,salesperson) and affix his own brand. How can he ensure the guarantee of quality from any goods purchased from open market ? Under what processes it has gone through ? What are the ingredients ? Whether the purchased goods have been manufactured under proper ratio of inputs or required heat or temperature etc.? Nothing can be said. Had the questioner used the word, 'job worker' instead of 'vendor', reply would have been different. Purchasing the goods from open market and affixing your own brand means no guarantee of quality. It means unbranded goods i.e. ordinary goods are being sold in the guise of branded goods. How far it is justified ? It cannot be digested.There is a quote---"Product is manufactured in the factory but brand is created in the mind." Buyer is swayed by the brand. If goods purchased from an open market and brand is affixed ? What does it mean ? When we purchase any branded goods from the market, we over-pay 50% as compared to the price of unbranded goods. This over-payment is because of good-will of brand name may be your own or another person.
If you want to affix your own brand, either you should manufacture the goods in your factory or get the goods manufactured from job-worker.
