Need help choosing the right India process?
Share your part requirements and Redstone will review manufacturability, landed cost, lead time, and quality requirements before quoting.
Why India
A lower-cost production path,
without losing control
India gives U.S. buyers qualified manufacturing capacity, competitive landed cost, and faster logistics while Redstone's U.S.-based team manages engineering, documentation, and quality communication.
Typical offshore sourcing
- Long freight timelines
- Time zone delays
- Unclear landed cost
- Harder supplier communication
- Quality issues found late

Logistics
U.S. customs and DDP pricing, handled end to end.
Redstone is the importer of record and handles U.S. customs brokerage on every India shipment. Every part is classified under the correct HTS code based on its final end use. Import duties are assessed at feasibility review and included in the DDP price quoted up front. The landed cost you approve at quote is the landed cost you pay.

Lead time 4 to 8 weeks
Shipping and lead time
Redstone is the importer of record and coordinates DDP ocean freight from India to your dock. Duties and freight are included in the DDP price quoted up front, so the landed cost you compare is the cost you pay. Plan for a longer total cycle than a Mexico or domestic program: ocean freight adds transit time on top of production. Production lead time confirmed at the feasibility stage by process.
Questions, answered
India production, the details that matter
What manufacturing processes does Redstone run in India?
Investment casting, sand casting, sheet metal fabrication, and CNC machining. Production runs in certified facilities across Rajkot (investment casting), Coimbatore (sand casting), and Bangalore (sheet metal and CNC). The U.S. Account Manager confirms which region and facility fit the program at the feasibility review.
How are duties and customs handled on India production?
We provide DDP pricing, which includes import duties and freight in the landed cost quoted at the feasibility stage. Redstone is the importer of record and manages customs clearance. The landed cost you approve at quote is the cost you pay at delivery.
What are the lead times for production in India?
Production lead times depend on process and volume, confirmed at the feasibility stage. Investment casting and CNC machining programs typically run 4 to 8 weeks of production time. Sand casting can run 6 to 10 weeks. Ocean freight from India to U.S. ports adds transit time on top. We quote the full timeline before you commit so you can plan accordingly.
Is India production quality auditable?
Yes. India facilities hold ISO 9001:2015 and IATF 16949. Full PPAP documentation, statistical process control records, and material traceability are available on request.
Can Redstone take over an existing program or move tooling to India?
Yes. Send the existing tool drawings, part history, and current supplier quote. We assess transfer feasibility, run a parallel quote from the appropriate India facility, and project landed-cost and lead-time impact before you commit. Existing tooling is often re-usable after assessment.
What are the major foundry clusters in India?
India's foundry industry is concentrated in regional clusters: Rajkot and Ahmedabad in Gujarat, Coimbatore and Chennai in Tamil Nadu, Kolhapur and Pune in Maharashtra, Belgaum in Karnataka, Howrah in West Bengal, and Ludhiana in Punjab. Redstone produces in the regions that fit each process: Rajkot for investment casting, Coimbatore for sand casting and ferrous work, and Bangalore for sheet metal fabrication and CNC machining.
How many foundries are there in India?
India has more than 5,000 registered foundries with an installed capacity of roughly 7.5 million tonnes per year, covering SG iron, aluminum, and steel production for automotive, agricultural, and industrial applications. Redstone audits every production facility before placing a program, with hard requirements including in-house CMM equipment, active ISO 9001 and IATF 16949 certification, and acceptance of ship-date commitments.
How should U.S. buyers choose a casting process in India?
The three main variables are material, geometry complexity, and volume. Iron or steel with intricate shapes and tight tolerances favors investment casting. Simpler geometry or lower volume fits sand casting, where tooling cost is lowest. Existing tooling and lead-time constraints matter as much as any fit chart, and the U.S. Account Manager confirms the process at the feasibility review.
