What Baldwin Filters makes

Baldwin Filters designs, manufactures, and distributes heavy-duty filtration for engines and mobile equipment. The line spans lube (oil) filters, air filters including cabin air, fuel filters and fuel/water separators, hydraulic filters, coolant and cooling-system filters, and transmission filters, backed by in-house filter media. The company's careers materials put the catalog at over 7,000 filter part numbers, and its filter-finder and cross-reference tools are built to match Baldwin parts against competitor numbers by application or VIN. The customer base is aftermarket and heavy duty first: trucking, construction, mining, agriculture, marine, and industrial machinery, with an automotive filtration line added through the 1995 purchase of Hastings Premium Filters.

Baldwin frames itself as a vertically integrated manufacturer, making both the finished filters and the media inside them. That vertical integration is visible in its trade record, where filter media (nonwoven rolls and filter paper) arrives alongside finished elements and filter hardware. As a heavy-duty OEM and aftermarket supplier, Baldwin sits in the tier structure as both a component maker and a branded aftermarket channel.

Ownership and history

J.A. Baldwin began producing an improved lube filter in Wisconsin in 1936. The company moved to Kearney, Nebraska in 1953, building on 42 acres of a former World War II air base, and expanded repeatedly through the 1960s and 1970s. In early 1981, Baldwin was purchased by J.L. Clark Manufacturing, the group that later became Clarcor. Under Clarcor, Baldwin expanded manufacturing capacity in Nebraska, added a technical center for research and testing, and opened facilities in Europe, Mexico, Australia, China, South Africa, and Morocco. In 1995 it acquired Hastings Premium Filters, adding a third US manufacturing site and an automotive line.

On February 28, 2017, Clarcor became part of Parker Hannifin Corporation, and Baldwin joined Parker's Filtration Group. Today Baldwin operates as a brand of Parker's Engine Mobile Aftermarket Division (EMAM). Parker Hannifin is a Fortune 250 company listed on the New York Stock Exchange under the ticker PH, with group revenue above $19 billion. Baldwin does not report a standalone profit and loss statement, so its own revenue and full multi-site headcount are not separately published; what is public is the brand's operating footprint and its parent's scale.

Manufacturing and distribution footprint

Baldwin's largest US site is its Kearney, Nebraska plant, which the company describes as nearly one million square feet. Its US manufacturing also includes a facility in Yankton, South Dakota. The Kearney distribution center, which the company likens to the size of six football fields, ships roughly 225,000 filters a day. The company describes safety as Parker's core value and enforces plant safety rules for visitors and staff. These are company-reported figures from Baldwin's own site, and they describe a high-volume manufacturing and distribution operation rather than a small job shop.

Certifications and quality

Baldwin's company description reports ISO/TS 16949 certification, the automotive quality management system now superseded by IATF 16949, along with a portfolio of patents on filter designs. That certification is reported as a claim; a current, dated certificate was not located on public sources during this review, so the quality signal is marked as claimed pending confirmation. Baldwin's engineering group states that it develops filtration for heavy-duty on-highway and off-road applications and runs a product-investigation procedure for field returns. Buyers evaluating Baldwin for a program should request the current PPAP package and a live certificate to confirm scope and cycle.

Known customers

Baldwin sells primarily through the heavy-duty aftermarket and to equipment channels rather than to a named set of OEM programs, and it does not publish a customer list. One documented brand relationship exists in the public record.

Beyond that sponsorship, the honest read is sector framing: Baldwin serves trucking, construction, mining, agriculture, marine, and industrial-machinery buyers through the aftermarket, and its cross-reference tooling is built to displace competitor part numbers on existing equipment.

Sourcing evidence

Baldwin's US import record reads like a global filtration brand consolidating a manufacturing network. There are 1,681 sea shipments on record since 2015, running at roughly 24.8 TEU per month, with the most recent shipment logged September 17, 2026. The largest single import category is nonwoven filter media (HTS 5603.94), followed by finished oil, fuel, and intake-air filters (HS 8421), filter paper (HS 4823 and 4811), and filter hardware in rubber, plastic, and steel. That is a coherent filtration bill of materials, media and elements in, finished product out, consistent with the company's vertical-integration claim.

Seven shown of 45-plus recorded suppliers. Four of the top seven are Parker Hannifin or Clarcor affiliates (Weifang, Parker Korea, Parker Hannifin European, Clarcor Filtration China), which is intercompany flow within the parent group rather than open-market purchasing. Active 2026 lanes also include HK Shenglian Car Fitting and Anhui Meiruier Filter in China, Hebei Filton in China, and Mahle Filtersysteme Austria and Irema Filter in Germany for media. The dominant origins are China, Taiwan, South Korea, Germany, and Japan, spanning nearshoring and long-haul lanes that carry real tariff exposure.

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. A recent single-month shipment count can read low because of manifest reporting lag. Absence of a record is not evidence of absence.
