Question 1

Who provides custom metal fabrication (build-to-print) services for export from India?

Accepted Answer

Custom fabrication capability is spread across many Indian manufacturers of varying scope. Buyers shortlist on genuine single-source capability, cutting, forming, welding, machining and finishing all in-house, rather than a project being quietly subcontracted across multiple shops. Vajra International offers build-to-print fabrication in Howrah under single-facility control from material procurement through finished, inspected parts.

Question 2

What is the HS code for custom fabricated metal parts exported from India?

Accepted Answer

Custom fabrication HS classification depends entirely on the specific product. Structural items typically fall under HS 73089090, while other fabricated articles may fall under HS 73269099 or a function-specific code. Confirm the exact subheading with your customs broker based on what the finished item actually is.

Question 3

What is the GST rate on custom metal fabrication in India?

Accepted Answer

Rate depends on the specific product's HSN classification, but most custom fabricated steel items attract 18% GST domestically. Exports ship zero-rated, under an LUT with no IGST or with IGST paid and refunded. An overseas buyer's FOB or CIF price carries only their own country's import duty, not Indian GST.

Question 4

What is the price of custom metal fabrication (build-to-print) from India?

Accepted Answer

Pricing depends entirely on the specific drawing. Material, complexity, welding and machining content, and finishing all vary project to project, so there's no meaningful generic price for "custom fabrication" as a category. Send your drawing for an accurate quote; this is the most drawing-dependent pricing category in the whole catalogue.

Question 5

What does "build-to-print" fabrication actually include?

Accepted Answer

Complete scope from your engineering drawing through to a finished, documented part or assembly: material procurement, cutting, forming, welding, machining and finishing, all coordinated as one project rather than you managing separate suppliers for each process step. This single-source approach is the main value versus piecing together cutting, welding and machining from different vendors yourself.

Question 6

What documents come with a custom fabrication export order?

Accepted Answer

Documentation gets scoped to the specific project and applicable standard, IS, ASTM or EN as relevant, commonly including Mill Test Certificates, welding records where applicable, dimensional inspection reports, finish certification, and a Certificate of Origin for duty relief. Confirm your project's exact documentation requirement at enquiry stage since custom work doesn't follow one fixed template.

Question 7

Is there a minimum order quantity for custom metal fabrication?

Accepted Answer

There's no fixed minimum. Build-to-print fabrication genuinely runs from prototype quantities through to full container loads on the same controlled process, one of the defining characteristics of a manufacturer offering this service versus one only set up for volume production.

Question 8

What is the lead time for custom metal fabrication from India?

Accepted Answer

Highly project-dependent. A simple bracket fabricates faster than a multi-process assembly needing cutting, forming, welding, machining and finishing in sequence. Share your drawing and process scope for a realistic lead time estimate rather than expecting a generic figure to apply across such a varied category.

Question 9

How do I know if a custom fabrication scope needs cutting, forming, welding, machining, or all of them?

Accepted Answer

This should come from your engineering drawing and specification. A competent fabricator reviews the drawing and identifies the required process sequence, which operations, in what order, as part of quoting, rather than you needing to specify the process route yourself. If you're unsure, share the drawing and ask for a process review.

Question 10

How do I check if a custom fabrication supplier genuinely does everything in-house?

Accepted Answer

Ask specifically which processes, cutting, forming, welding, machining, finishing, are performed in their own facility versus subcontracted. A supplier quietly subcontracting key steps introduces quality-control gaps and communication delays you won't see until something goes wrong. Ask for a facility tour or photos, and a reference project spanning multiple processes.

Question 11

Does custom fabricated metalwork from India meet international project standards?

Accepted Answer

Yes, when built to the applicable standard your project specifies. Indian custom fabricators commonly work to relevant IS, ASTM or EN standards depending on the component type, structural, electrical, mechanical. Always name the specific standard for your project rather than assuming general ISO 9001 certification covers every applicable technical requirement.

Question 12

Can custom fabrication combine multiple materials in one assembly?

Accepted Answer

Yes. A single-source fabricator can combine mild steel, stainless steel, aluminium and copper within one assembly where the design calls for it, a copper busbar terminal welded into a steel enclosure for example, coordinating the different process requirements each material needs rather than you sourcing each material's fabrication separately.

Question 13

What finishing options are available for custom fabricated components?

Accepted Answer

Hot-dip galvanizing, powder coating, painting and plating are all available, selected per the component's service environment and specification. Custom fabrication projects often combine a structural finish, galvanizing, with a functional one, plating on specific contact surfaces, within the same assembly. Specify this detail on the drawing.

Question 14

How is quality controlled across a multi-process custom fabrication project?

Accepted Answer

Inspection should happen at each process stage, cutting, welding, machining, as well as final dimensional and finish verification against the drawing, not just a single check at the end. Ask your supplier how they control quality through a multi-step process, since errors caught late, after finishing, are far more expensive to fix than errors caught mid-process.

Question 15

Which region of India is best for sourcing custom metal fabrication?

Accepted Answer

Kolkata/Howrah manufacturers with broad in-house capability, cutting, forming, welding, machining, finishing, under one roof reduce the coordination burden of a custom project versus a region where you'd need to manage several specialist subcontractors yourself.

Question 16

Can custom fabrication projects be scaled from prototype to full production volume?

Accepted Answer

Yes, with a supplier set up for both: prototype or first-article validation followed by scaling to production quantities on the same process and documentation, without needing to re-source or re-qualify a different supplier for volume. Confirm this scalability explicitly if your project may grow from a pilot to a larger order.

Question 17

What information should I include in a custom fabrication enquiry to get an accurate quote?

Accepted Answer

A complete engineering drawing (dimensions, tolerances, material spec, finish requirement, applicable standard), quantity, prototype or production, and expected future volume, and any specific inspection or documentation requirements. The more complete the drawing, the faster and more accurate the quote; incomplete drawings are the single biggest cause of quoting delays in custom work.

Question 18

Can Vajra fabricate a component that isn't in the standard product catalogue?

Accepted Answer

Yes, that's precisely what build-to-print custom fabrication covers: project-specific metalwork outside the standard catalogue, built to your drawing rather than a stock design. If it's not a listed product category, describe the requirement and send any available drawing for review.

Question 19

What does 'build-to-print' mean in your shop?

Accepted Answer

The customer's drawing defines the part; we handle material procurement, cutting, forming, welding, machining, finishing and inspection. The customer doesn't manage the supply chain or the process, only the spec and the schedule. Most OEM exports and EPC sub-assemblies are bought this way.

Question 20

Which materials and processes are covered under one roof?

Accepted Answer

MS, SS, aluminium, copper and structural steel for the material side; laser/plasma/oxy cutting, press-brake forming, CNC machining, MIG/TIG/SAW welding, HDG/powder/painting, deep-drawing, all in-house or via dedicated partners in our cluster. The customer sees one supplier, one delivery, one invoice.

Question 21

What volumes are economical?

Accepted Answer

From single prototype assemblies to full-container-load production. Below 5 pieces the setup cost dominates; from 50 pieces up the part cost is stable; above 5,000 we tool up to bring it down further. Most export work sits in the 100–2,000 piece-per-batch range.

Question 22

How is quality assured on a custom assembly?

Accepted Answer

Material certs at input, dimensional check at fabrication, weld inspection (visual, MPI, UT per drawing), galvanizing or paint thickness, functional test where applicable, final FAI on first batch. Reports travel with the consignment in PDF and physical form.

Question 23

Can you handle a customer's drawings in different CAD formats?

Accepted Answer

Yes. DWG, DXF, STEP, IGES, native SolidWorks/Inventor/CATIA files are routine inputs. We convert, verify against the PDF drawing, and start the manufacturing process from a controlled CAD baseline. Drawing revisions are tracked.
