What MultiParts makes

MultiParts Supply USA, which trades as Multi Parts Solutions or MPS, is an aftermarket parts developer and supplier rather than a factory operator. The company designs, engineers, sources, tests, and ships non-discretionary replacement parts for passenger cars, commercial trucks, and off-highway equipment, and it does so through a network of vetted manufacturing partners built up over more than 35 years. Asked on its own site whether it runs its own factories, the answer is direct: no, and the company frames that as a feature, because it can match each part to the best factory for the job rather than to a fixed plant.

The catalog centers on a handful of vehicle systems. Fuel-system parts include fuel pumps, fuel modules, pressure control valves, fuel vapor valves, and diesel fuel lines. Cooling parts cover water pumps, auxiliary cooling pumps, thermostats, temperature sensors, coolant hoses, and electric heater valves. The company also builds clutch and brake hydraulics such as master and slave cylinders, wheel cylinders, and hydraulic clutch assemblies, plus emissions parts (DEF heaters, vapor canisters, oil separators, EGR valves) and engine-management components. Its US import records add power steering pumps and rack-and-pinion assemblies to that picture. Beyond light vehicles, the ACC Heavy Duty division serves the commercial truck and trailer market, and the HKX division, added in 2026, supplies auxiliary hydraulic kits and control systems for excavators and heavy equipment.

The service wrap is where MPS positions itself against a plain distributor. It offers full product-lifecycle development with a stated bench of 10-plus product managers and 30-plus engineers, testing and validation the company says it has invested more than 10 million dollars in, global sourcing and logistics, and quality control from concept through delivery. For brand owners, it develops private-label and exclusive parts, handles branding and packaging, and will sign exclusivity agreements so a part belongs to one customer. Standard lead time for a part it already makes is about 60 days. The model is closest to an outsourced product development and sourcing team for aftermarket brands, Tier 1s, and fleets.

Ownership and history

MultiParts was founded in 1988, originally as Spectrum International, and is headquartered in Jupiter, Florida. Chief Executive Officer Brian Cohn has led the business for two decades and was president of the predecessor company from the mid-1990s, so the current company carries a long single-owner lineage rather than a recent startup arc.

In April 2023, private-equity firm Radial Equity Partners announced a partnership with and recapitalization of Multi Parts, described in trade coverage as a supplier of non-discretionary replacement parts to the vehicle aftermarket. Terms were not disclosed. That backing has funded a two-step expansion into heavy vehicles. In January 2024, MPS acquired American Chrome Company, a heavy-duty truck and trailer parts supplier founded in 1983 by the Hou family, and now runs it as the ACC Heavy Duty division from a distribution center near Chicago. In August 2026, MPS acquired HKX, Inc., a Monroe, Washington maker of auxiliary hydraulic kits and controls for excavators, establishing a third operating division and moving the company into the construction-equipment market. The result is a group organized around three divisions, MPS Automotive, ACC Heavy Duty, and HKX, with operations across four sites on three continents.

Global footprint

MultiParts runs a distributed operation rather than a single campus. Corporate leadership, engineering, and product development sit at the Jupiter, Florida headquarters. European sales, customer service, product development, and supply-chain work run out of Multi Parts Poland in Warsaw. An Asia-Pacific hub in Shanghai, with a recently expanded warehouse and office, manages manufacturing partners and regional supply chain. The ACC Heavy Duty division operates from a distribution center in the Chicago area. The company describes its team as 100-plus professionals across three continents, with the engineering, product-management, sales, and supply-chain functions split across the US, Poland, and China sites. The interactive map on this page shows each location and what it does.

Certifications and quality

MPS states that it operates ISO 9001 certified quality management systems and runs quality control from the first sample through final delivery, checking each batch against a customer's specifications and the relevant international standards before it ships. The company does not publish a dated certificate for the parent entity, so the ISO 9001 claim is reported here as a company claim rather than a verified current cycle. Its ACC Heavy Duty division is on firmer documented ground: the Bolingbrook, Illinois distribution center is described as ISO 9001 and ISO 14001 certified in the 2024 acquisition announcement. MPS also cites inspection capabilities including 3D scanning and X-ray metallurgy as part of its testing and validation function.

Known customers

MultiParts is a private-label and turnkey developer, which by design keeps its customer list confidential. The company says it supplies full-line manufacturers, leading global brands, private-label brands, Tier 1 suppliers, and fleets, and that many customers work with it on an exclusive basis so their parts are theirs alone. No individual end customer meets the documented or reported evidence bar, and the US customs record shows the importer of record is MPS's own captive supply entity rather than named brand buyers, so this profile does not assert specific customer names. Buyers evaluating MPS should expect a supplier whose whole proposition is to sit behind a brand rather than in front of it.

Sourcing evidence

MultiParts' US import record reads exactly like an asset-light, Asia-anchored aftermarket developer. The Jupiter importing entity has 624 US sea shipments on record from July 2018 through September 2026, averaging about 2.2 TEU per shipment and roughly 36.7 TEU per month, with the most recent shipment logged on September 23, 2026. ImportYeti estimates cumulative ocean shipping spend near 1.9 million dollars, with cost data covering about 58 percent of shipments, which makes it an order-of-magnitude figure rather than an audited one. The single most important pattern is concentration in the company's own supply arm.

Multi Parts Supply China, the company's own captive entity in Jiading, accounts for 517 of the 624 shipments, about 83 percent. That is the customs signature of the business model MPS describes on its own site: engineer and source parts through a global manufacturing network, then import them to the US under its own and its customers' brands. The declared goods match the catalog, dominated by fuel pumps, cooling pumps, and steering assemblies under HTS headings for pumps (8413.30) and steering parts (8708.94). By origin, the record is roughly 86 percent Asia (China 505 shipments, Vietnam 22), with Portugal a notable second region at 78 shipments and small volumes from Turkey, Brazil, and Mexico, a spread that matters to buyers weighing tariff exposure and dual-sourcing. A recent example: on September 23, 2026, the China entity shipped motor-vehicle power rack-and-pinion assemblies, about 13.3 tonnes in one container, via MSC on the Asia to US Pacific lane.

Coverage caveats apply. These are US ocean-freight records only, so air, truck, and rail movements do not appear, and cross-border North American flows are largely invisible. Many bills are freight-forwarder house bills, and product categories come from declared manifest codes, which are noisy. Because the record is dominated by intra-group shipments, it describes MPS's own sourcing footprint well but says little about which brands ultimately buy the finished parts. Absence of a record is not evidence of absence.
