How Switching to U.S.-Made Indium Solder Materials Can Help Control Costs
How Switching to U.S.-Made Indium Solder Materials Can Help Control Costs
Tariffs on imported electronics materials — including solder paste, wire solder, and flux — have increased costs for electronics manufacturers sourcing from overseas suppliers. Indium Corporation is a U.S.-based refiner, smelter, manufacturer, and supplier of solder materials to global electronics, semiconductor, thin-film, and thermal management markets. Because Indium Corporation manufactures in the United States, their solder paste and wire solder products are not subject to the same tariff exposure as imported alternatives — making a switch to Indium a practical cost-control strategy for manufacturers currently sourcing from overseas. MTE Solutions carries the full Indium solder line, including leaded and lead-free solder paste and wire solder, in stock and ready to ship.
Why Tariffs Are Affecting Solder Material Costs
Solder materials — particularly tin, silver, and bismuth alloys used in SAC305 and other lead-free formulations — are sourced globally, with significant production in Asia. Tariffs on imported goods from key solder-producing regions increase the landed cost of imported solder paste and wire solder, which suppliers pass through to manufacturers. For high-volume electronics assembly operations, solder paste and wire solder are significant recurring consumable costs — even modest per-unit price increases compound quickly across production volumes. Switching to a U.S.-manufactured solder brand eliminates tariff exposure on the finished product and reduces supply chain risk from international shipping delays and currency fluctuations.

Frequently Asked Questions
Are Indium Corporation solder products actually manufactured in the United States?
Yes — Indium Corporation is headquartered in Clinton, New York, and manufactures solder paste, wire solder, flux, and other materials at U.S. facilities. As a U.S.-based manufacturer, their finished solder products are not subject to tariffs on imported goods from overseas solder-producing regions. This makes Indium a direct cost-control alternative for manufacturers currently sourcing solder paste or wire solder from imported brands affected by tariff increases.
Is Indium solder paste a drop-in replacement for my current imported solder paste?
In most cases, yes — but any solder paste substitution in a qualified or validated process requires a formal change control and process validation. Key parameters to validate include stencil printing performance (slump, release, print definition), reflow profile compatibility, flux residue characteristics, and joint reliability on your specific substrate and component mix. Indium Corporation provides detailed technical data sheets and application support for qualification. Contact MTE Solutions for TDS documentation and to discuss your specific application requirements before switching.
What is the difference between Indium NC-SMQ92J (leaded) and 8.9HF (SAC305 lead-free)?
NC-SMQ92J is a leaded eutectic solder paste (63% tin, 37% lead) with a melting point of 183°C — used for non-RoHS applications where leaded solder is permitted or required (military, aerospace, medical devices exempt from RoHS). 8.9HF is a lead-free SAC305 paste (96.5% tin, 3% silver, 0.5% copper) with a melting point of approximately 217°C — required for RoHS-compliant consumer electronics and any product sold in markets requiring lead-free compliance. Both are no-clean formulas manufactured by Indium Corporation in the USA.
