While China manufactures at scale, in India most factories are small and midsize. The government too favours SMEs and the country’s regulations are designed to protect them.
There are also tons of large enterprises, and these are mostly in industries such as apparel, textiles, chemicals, pharmaceuticals, machinery, electronic components, auto & parts.
For most products relevant for private label sellers, the manufacturers would be smaller factories. Many factories are family-run businesses so don’t be surprised to see two generations attend a meeting with you if you visit their factory.
