What this tells a buyer
The import mix is dominated by hydraulic valves, valve housings, and castings under HS 8481, the profile of a valve and control-systems manufacturer bringing in sub-components for domestic assembly rather than a reseller importing finished goods.
One of the largest recorded suppliers, HUSCO Automotive Shanghai, is the company's own Chinese operation, so a meaningful share of the customs record reflects intercompany lanes rather than arms-length vendors.
Shipments arrive as small less-than-container loads averaging about 0.1 TEU each, consistent with a steady flow of precision valve components; the most recent recorded ocean shipment was March 2026 from an Italian hydraulics supplier.

What HUSCO International makes
HUSCO International designs and manufactures hydraulic and electro-mechanical control systems for two markets: off-highway equipment and automotive powertrains. The off-highway division builds customized hydraulic solutions for agricultural, construction, material handling, and commercial machinery, translating operator commands into machine motion. Its product families include the MX pressure-compensated load-sense sectional valve platform, electro-hydraulic poppet valves (EHPV), electronic pressure relief valves, the E-Control electro-hydraulic line, and the INCOVA intelligent valve system that replaces conventional spool valves with electronic control.
The automotive division makes electro-hydraulic and electro-mechanical components that improve fuel efficiency, driving performance, and safety across internal-combustion, hybrid, and electric vehicles. Product lines cover cam phasing and variable valve timing valves, variable oil pump control, cylinder deactivation, transmission control solenoids, linear force and variable bleed solenoids, driveline disconnect actuators, and park-lock solenoids. The company began automotive production in 1999 with the Active Body Control suspension system for Mercedes-Benz, and cam phasing valves that each reduce fuel consumption by 1 to 6 percent per engine valve followed in 2000. In 2026 HUSCO added in-house plastic injection molding through the acquisition of Mayfair Plastics.
HUSCO focuses its engineering on a small number of leading OEM customers, co-developing platforms rather than selling catalog parts. Its automotive team uses finite element analysis, computational fluid dynamics, magnetic analysis, and Creo 3D modeling in development.
Financial performance
HUSCO is privately held and does not publish audited financials. Per the company's own materials, global revenue surpassed $500 million in 2025, up from a then-record $400 million-plus in 2017, when its China operations first passed $100 million in annual sales. The company reports more than 1,500 employees across 10 global sales and manufacturing locations, and describes itself as the largest corporate charitable donor in Wisconsin. Growth has been contract-driven: the company has cited a $50 million-per-year electric-vehicle efficiency contract, more than $40 million in new off-highway contracts awarded in 2022, and roughly $200 million in newly awarded projects announced at a 2024 manufacturing event.
Ownership and history
HUSCO's roots trace to 1946, with the Hydraulic Unit Specialties Company name registered in Waukesha, Wisconsin in 1947 by founder Dana Schneider. The Koehring company acquired it in 1968, and Koehring later passed to AMCA International, which Agustin (Gus) A. Ramirez, Jr. joined in 1981 to lead strategic planning. Gus Ramirez led a management buyout of HUSCO from AMCA in late 1985, establishing Husco International, Inc. as an independent, family-owned company, which it remains today. Austin Ramirez, who returned to the business after the University of Virginia and the Stanford Graduate School of Business and served a term as a White House Fellow, became CEO in 2017; Gus Ramirez serves as Chairman. The company's world headquarters is at 2239 Pewaukee Rd. in Waukesha, with additional operations in Iowa, Michigan, England, China, India, Brazil, and Germany. HUSCO opened its first international facility in the United Kingdom in 1984, its Shanghai facility in 2001, and its Pune, India facility in 2007.
Certifications and quality
HUSCO's quality record is validated by its customers rather than by a single public certificate. Its Waukesha automotive operations earned the 2025 GM Supplier Quality Excellence Award, announced in August 2026, and the company has received Ford Q1 certification, an FCA (Stellantis) outstanding-quality recognition, and Caterpillar Supplier Quality Excellence Process (SQEP) Bronze certification. Its UK facility attained ISO 50001 energy-management certification in 2023. IATF 16949 is the automotive-sector quality-system norm for a direct powertrain supplier of this scale; HUSCO's third-party quality awards from GM, Ford, FCA, and Caterpillar reflect quality systems in current use. The company runs advanced product quality planning and production part approval as standard practice with its automotive customers.
Known customers
HUSCO co-develops platforms with a concentrated set of major OEMs. Several relationships are on the public record through the company's own announcements, awards from the customers themselves, and major-outlet coverage.
Customer | Evidence | Confidence | As of |
|---|---|---|---|
General Motors | 2025 GM Supplier Quality Excellence Award to HUSCO's Waukesha automotive operations, company announcement | Documented | Aug 2026 |
Ford | Ford Q1 certification and Preferred Suppliers listing, company announcements | Documented | 2013 |
Caterpillar | Caterpillar SQEP Bronze certification, company announcement | Documented | 2019 |
Hyster-Yale | Modular electro-hydraulic valve platform co-developed for the truck line; supplier for 25-plus years, company announcement | Documented | 2022 |
Mercedes-Benz | Active Body Control suspension system, first automotive product into production in 1999, company history | Documented | 1999 |
Company materials and third-party profiles also name John Deere and FCA (Stellantis) among served manufacturers. The off-highway customer base spans agricultural, construction, and material-handling OEMs including NACCO Material Handling Group.
Sourcing evidence
HUSCO's US import record reads like a manufacturer's, not a reseller's: 10,136 US sea shipments on record since 2015, dominated by hydraulic valves, valve housings, castings, and components rather than finished goods. Declared codes cluster in HS 8481 (taps, cocks, valves and similar appliances) and HS 8708 (motor-vehicle parts), consistent with a valve and control-systems maker importing sub-components for domestic assembly. The most active foreign suppliers on record:
Supplier | Country | Shipments | Typical goods |
|---|---|---|---|
China Source Components Trade | China | 723 | Hydraulic valves, valve housings |
Fonderia Zardo | Italy | 502 | Castings, valve housings |
Acwa Automatics | India | 462 | Engineering valves, components |
HUSCO Automotive Shanghai | China | 452 | Intercompany automotive components |
Qijing Machinery | China | 393 | Machined valve components |
G Plast | India | 389 | Plastic and aluminum parts |
Rollon Hydraulics | India | 373 | Hydraulic components |
Shipments arrive as smaller less-than-container loads, averaging about 0.1 TEU each, which fits a flow of precision valve components rather than bulk goods. The most recent recorded sea shipment was March 6, 2026, from an Italian hydraulics supplier. One of the largest suppliers, HUSCO Automotive Shanghai, is the company's own Chinese operation, an intercompany lane rather than an arms-length vendor. ImportYeti estimates cumulative ocean-freight spend at roughly $10.5 million across the period, with cost data covering about 55 percent of shipments, an order-of-magnitude figure rather than an audited one.
Coverage caveats: these are US ocean-freight records only. Air, truck, and rail movements do not appear; some records name freight intermediaries rather than manufacturers; and product categories come from declared manifest codes, which are noisy. Absence of a record is not evidence of absence.
