How to Buy Alloy 20 Valves from India to the USA
Import guide · Supreme Valves India · June 2026
US plant engineers, mining contractors, and MRO procurement teams increasingly source Alloy 20 (UNS N08020 / CN7M) valves directly from Indian manufacturers to avoid domestic distributor markups and Chinese tariff penalties. This guide walks through the end-to-end process — from RFQ to valve installation at your US facility.
Step 1: Define your valve specification
Before contacting a supplier, prepare a line-item specification:
- Valve type (gate, globe, ball, dual-plate wafer check)
- NPS size and pressure class (typically Class 150 or 300)
- Body material: Alloy 20 / ASTM A351 CN7M (specify full-material construction for check valves)
- End connection: RF flanged per ASME B16.5, or wafer profile per API 594
- Design standard: API 600, 603, 608, 623, or 594 as applicable
- Test standard: API 598 hydrostatic
- Service media: e.g., sulfuric acid 97%, raffinate loop, phosphoric acid
- Quantity and delivery location (city, state, ZIP)
Use our RFQ configurator or email the specification directly.
Step 2: Receive quotation and proforma invoice (USD)
Indian valve exporters quote in United States Dollars (USD) for US buyers. The proforma invoice (PI) includes:
- Unit price per valve size and type
- Air freight cost (if DAP terms — typically included in unit price)
- Incoterms (DAP destination city is standard for US direct-buy)
- Payment terms (typically 50% advance wire transfer, 50% before dispatch)
- Lead time (8–10 weeks for Alloy 20 cast valves)
- Exchange rate reference (if applicable)
Step 3: Wire transfer payment
Payment is made via international SWIFT wire transfer to the supplier's bank. You will need:
- Beneficiary name and address
- Bank name, branch, SWIFT/BIC code
- Account number and IFSC code (for Indian banks)
- Reference: PI number and GST/IEC details
Retain the MT103 SWIFT confirmation as proof of payment for your accounts payable records.
Step 4: Manufacturing, testing, and documentation
During the 8–10 week lead time, the supplier:
- Orders CN7M castings from an approved foundry
- Machines body, disc, stem, and trim components
- Assembles and pressure-tests per API 598 (shell 1.5× WP, seat 1.1× WP)
- Issues EN 10204 Type 3.1 Material Test Certificates with foundry heat analysis
- Export-packs in wooden cases with silica gel desiccant
Step 5: Shipping and US customs clearance
Under DAP Incoterms 2020, the supplier's responsibilities end when goods are ready for unloading at the destination airport. Your responsibilities as the US buyer:
- Import customs clearance: Engage a licensed customs broker to file entry with US Customs and Border Protection (CBP)
- Duties and tariffs: Indian-origin valves under HS 84818030 are not subject to Section 301 China tariffs — only standard MFN duty rates apply
- Inland transport: Truck from destination airport (e.g., LAS, IAH, TPA) to your facility
- Unloading: At your warehouse or job site
Tariff advantage: Valves manufactured in China face 25% Section 301 tariffs under HTSUS 8481. Indian-manufactured Alloy 20 valves avoid this penalty, often saving 20–30% on landed cost compared to Chinese alternatives even before considering material quality differences.
Step 6: Installation and MRO re-order
On receipt, verify:
- Valve marking matches PO specification (size, class, CN7M material stamp)
- MTC heat number matches body casting mark
- Hydrostatic test certificate is included
- No shipping damage to flange faces or wafer profile
For MRO re-orders, reference the original PI number and MTC heat number for identical material traceability.
