Manufacturer & supplier to Japan
Stainless steel, duplex, nickel alloys and carbon steel — plate, pipe, fittings, flanges and fasteners — shipped from Mumbai to Japan. Japanese buyers usually name the JIS (SUS) designation alongside ASTM — tell us which designation the certificate must show, and whether you will claim India–Japan CEPA preference for your HS code.

Grades most asked forJIS ↔ ASTM Equivalents for Japanese Projects
Japanese specifications use SUS and NCF designations. The chemistry of each pair below matches closely, but the standards differ in tolerances and test details — confirm acceptance before substituting one for the other.
For 904L pipe and tube see 904L pipe (SUS890LTP / SUS890LTB).

Products we export
Export to Japan — questions
Do you ship to Japan?
Yes. We ship by sea from Nhava Sheva (JNPT), Mumbai, FOB or CIF, to ports including Yokohama, Tokyo, Kobe, Osaka, Nagoya.
Which documents come with an export shipment?
Commercial invoice, packing list, bill of lading, certificate of origin and EN 10204 3.1 mill test certificates; 3.2 certificates and third-party inspection reports when ordered. Legalisation or attestation can be arranged where the destination requires it.
Can you quote in USD?
Yes — quotations are available in USD or INR, with Incoterms of your choice (usually FOB Nhava Sheva or CIF your port).
Is 904L the same as SUS890L?
They are equivalent: SUS890L is the JIS designation corresponding to UNS N08904 (904L). Pipe is SUS890LTP to JIS G 3459; heat-exchanger tube is SUS890LTB to JIS G 3463.
Can the mill certificate show JIS designations?
Material is made and certified to ASTM / ASME. Where your project accepts it, the certificate can show the JIS equivalent alongside — tell us the exact JIS standard and grade at enquiry.
Do you provide the India–Japan CEPA certificate of origin?
Where your tariff line carries duty and you claim preference, we apply for it from the issuing authority in India (Export Inspection Council). Many steel lines already enter Japan duty-free, so check the HS code first.
