Hello aspirant.

Best NITs for Chemical Engineering are

• NIT Tiruchirapalli
• NIT Suratkal
• NIT Warangal
• NIT Allahabad
• NIT Calicut
• NIT Jaipur
• NIT Rourkela
• NIT Nagpur
• NIT Surat
• NIT Bhopal

If it comes to NIT or ICT Mumbai then if it's one of the top NIT offerings you Chemical Engineering I suggest you to go for it so that if you excel you will get better placement with a good package. But if it's not a top NIT then go for ICT Mumbai.

Hope this answer helps you.

All the best!!!!
