Sampling Associates International LLC

What Sampling Associates International LLC does

Sampling Associates International LLC (SAI) is a privately held industrial services company founded in 1982 and headquartered in Hampton, Virginia. SAI operates and maintains mechanical sampling equipment at bulk terminals that handle coal, coke, and petroleum coke for export and domestic use. The company's core offering is an integrated Operations and Maintenance (O&M) program covering operation of mechanical sampling systems, preventive maintenance, equipment repair, and sampling system design and audits. SAI holds contracts at all 17 US export terminals equipped with mechanical sampling systems and extends its reach internationally through an affiliate network that includes SAI Gulf (US Gulf Coast), Incolab Services International (Mexico, Colombia, Venezuela), Sabine Surveyors, A.J. Edmond, and Certispec.

SAI does not manufacture sampling systems; rather, it operates and improves equipment made by third-party manufacturers. Its proprietary contribution is the Mechanical Part-stream Sampler (MPS), co-developed with Precision Samplers, Inc. (patent pending), which serves as a lower-footprint, lower-cost alternative to full multi-stage sampling systems. The company's service technology is grounded in decades of operational know-how, comprehensive Preventive Maintenance programs, and ASTM/ISO standards expertise—company officers chair the ASTM Task Group on Mechanical Sampling, ASTM Subcommittee D05.27, and ISO Subcommittee TC27/4. SAI markets its differentiation as the highest 'on-line' equipment availability in the industry.

SAI generates revenue through long-term contracted O&M service agreements with terminal operators (CONSOL Marine Terminal, CSXT Curtis Bay, Kinder Morgan, Norfolk Southern, Metro Ports, United Bulk Terminal, Total Port Arthur, Stockton Terminal, and others). The company sells directly via enterprise field sales with field-based operations and maintenance teams stationed at or regularly visiting terminal locations. Pricing is not publicly disclosed. Customer acquisition is driven by relationship-based B2B selling reinforced by technical publications, industry standards leadership, and 40+ years of trusted independent third-party service.

Products and services

• Operation of Mechanical Sampling Systems On-site operation of mechanical sampling systems at customer terminals, covering safety compliance, system monitoring, sample ratio monitoring, and Preemptive Quality Management (PQM) documentation for bulk operators of coal, coke, and petroleum coke.
• Maintenance of Mechanical Sampling Systems Comprehensive maintenance services for mechanical sampling systems, including Preventative Maintenance (PM) programs, equipment repair, and supporting documentation, delivered to operators of coal, coke, and petroleum coke terminals.
• Sampling System Design, Audits, & Equipment Repairs Engineering services covering mechanical sampling system design and specifications, comprehensive audits of existing systems, equipment restoration and redesign, and contracted maintenance — for bulk terminal operators handling coal, coke, and petroleum coke.
• Mechanical Part-Stream Sampler (MPS) A patent-pending sampling device developed with Precision Samplers, Inc. for part-stream cut sampling of bulk materials from moving conveyors. Built with stainless-steel construction and two alternating sample scoops with programmable sampling frequency, the MPS is designed for 'Condition C - Part-stream Cut' sampling per ASTM D6609 and serves as a backup/alternative when full mechanical sampling systems are inoperative or uneconomical.
