Customer names are confidential — but the work, the methodology, and the measurable outcomes are not. Six anonymized case studies from active RK programs across the verticals we serve.
A field engineer in Hsinchu pings the global service desk: a critical sub-fab module just failed. The customer fab is offline at $1M+ per hour. By 4:01 a.m. RK's after-hours service-parts team had the part picked, packaged, and on a courier toward SFO. Twenty-three hours later it cleared customs in Taipei. The customer fab returned to volume the same day. The service-parts program has been running like that for thirty-five years.
Mission-critical spare parts for a global semiconductor equipment leader.
The customer
One of the world's largest manufacturers of semiconductor capital equipment. Operates fab-installed tooling at virtually every leading-edge chip manufacturer globally. RK has served this customer continuously for more than three decades.
The challenge
Tool-down events at a customer FAB cost the chip manufacturer extraordinary amounts per hour. The semiconductor capital equipment company is contractually responsible for getting the right service part to the right field engineer in the shortest possible time, no matter where in the world the FAB sits. The historical 3PL pattern — generic warehousing, batch shipping, manual exception handling — was structurally incapable of meeting the SLA.
The RK solution
RK designed and operates a dedicated multi-facility service-parts program: precision-managed spare-parts inventory in geographically positioned facilities, integrated to the customer's tooling and service-management systems, with white-glove delivery directly into FAB cleanrooms by RK's trained operators. Six-sigma+ quality is the operational baseline, not a stretch goal — measured continuously and reported transparently to the customer.
What changed
Time-critical service parts move from RK warehouse to FAB receiving in hours, not days. Field engineers no longer carry inventory in their service vehicles. Spare-parts working capital is centrally managed and continuously optimized. Most important: the customer's service-level commitment to the chip manufacturers it serves is met at six-sigma quality, every quarter, every year — through cycles, expansions, and pandemic-era stress tests.
“Thirty-five years and we've never had to put a service-parts program out to bid. The math just keeps working.”

An ocean carrier dropped two of the customer's containers off-schedule at the Port of Long Beach — a 27-hour dwell against a 6-hour expectation. The Inbound Control Tower flagged the dwell within 60 seconds. The exception agent had a replacement drayage carrier dispatched in under five minutes. The components reached the assembly plant in time for the 11 p.m. shift change. The production planner found out at the next morning's stand-up — by which time the variance was already closed.
Inbound control tower for a high-growth EV manufacturer.
The customer
A high-growth electric vehicle manufacturer scaling U.S. assembly capacity. Inbound supply chain spans multiple ocean lanes plus a high-volume cross-border flow. The cost of a production-line interruption — even for hours — is significant.
The challenge
The customer's inbound flows arrived through three structurally different paths, with three different carrier sets, three different latency profiles, and three different customs paths. The customer's planning team was spending headcount weeks per month just trying to answer "where is it?" — a question that should not consume planner time at scale.
The RK solution
RK's Innovation Center designed and stood up an Inbound Control Tower purpose-built for this customer: real-time visibility from origin through eight in-transit pipeline stages, native FTZ handling for duty-deferred imports, integrated SAP synchronization with the customer's ERP, and exception-by-exception agent triage. RK staffs the operation. The customer sees the same dashboard RK does.
What changed
Production planners no longer spend headcount weeks chasing inbound visibility. Detention & demurrage charges are caught upstream, not after the bill arrives. Customer-reported ROI on the RK engagement runs at a meaningful multiple of the fee. And the customer's production line continues to run.
“They're the only operator we trust to run inbound on a brand-new vehicle program. We don't have to manage them — they manage the program.”

Twelve calendar years of EV-grade lithium cells handled at Kato Road. UN 38.3-tested cells unloaded by HazWoper-trained operators, segregated by chemistry and state-of-charge, stored to NFPA 855, sequenced line-side at takt to the customer's production cadence. Through that decade-plus tenure the program has logged zero recordable safety incidents. The customer's manufacturing leadership doesn't budget time to think about battery logistics.
Battery storage & line-side delivery for a major battery manufacturer.
The customer
One of the largest battery manufacturers operating in the U.S. EV-grade large-format cells and packs require hazmat-certified handling, regulatory-compliant facilities, and absolute chain-of-custody discipline.
The challenge
Battery handling is unforgiving. The category requires hazmat-certified operators, purpose-built facility environmental controls, fire-risk discipline, and synchronized delivery into the customer's production cadence — without compromise on safety. Standard warehouse operators are not configured for this category.
The RK solution
RK's flagship Kato Road facility in Fremont, California is purpose-built for this category. Hazmat-certified operators, environmental controls, and chain-of-custody discipline embedded across every shift — a practice RK has run continuously since 2014. RK sequences inbound batteries to the customer's production takt time and delivers line-side at the customer's cadence.
What changed
The customer offloads the entire complexity of battery storage, hazmat compliance, and synchronized line-side delivery to a partner who has been doing it since 2014. The customer's manufacturing leadership focuses on cell chemistry, manufacturing yield, and capacity expansion — not on logistics fire drills.
“The thing we don't talk about is the thing that makes the operation work. We don't talk about batteries — because they're handled.”
The customer's CFO had eight figures of working capital trapped in deferred customs duties at year-end — components that had been imported, kitted, and re-exported, but on which full duty had been paid. RK consolidated the operation into a single Foreign Trade Zone with integrated VAS kitting and B2B fulfillment in customer-branded packaging. ERP-to-WMS sync ran at 99%+. Deferred and eliminated duty turned into recovered working capital. The CFO got the call before the close.
FTZ & integrated B2B fulfillment for a global electronics manufacturer.
The customer
A multinational high-precision electronics manufacturer with a complex bill of material, global supplier base, and U.S. distribution serving hundreds of B2B accounts. Imported components need bonded handling. Outbound flow needs to be reliable, branded, and audit-ready.
The challenge
The customer was paying full duty on imported components that subsequently shipped back out of country, leaving working capital permanently captured by Customs. Outbound B2B fulfillment was running on a separate system and a separate vendor, creating reconciliation gaps and brand-experience inconsistency.
The RK solution
RK consolidated the customer's U.S. operation into a single integrated program: a Foreign Trade Zone facility for duty-deferred and duty-eliminated imports, value-added kitting and configuration, and B2B fulfillment in customer-branded packaging — all integrated to the customer's ERP via real-time WMS sync. One operation, one system of record, one vendor accountable.
What changed
Working capital tied up in deferred-and-eliminated duties was recovered. ERP-to-WMS sync runs at 99%+ reliability. Outbound brand experience matches the customer's standards because RK operators run it under the customer's own packaging and SLA discipline.
“We didn't realize how much working capital was being eaten by our 3PL setup until we replaced it. The recovery hit the close.”
Operating vignette · Construction takt cadence · 2025–2026.
An eight-figure delivery of pre-configured 42U racks arrives at the buildout site. The site GC has a four-hour staging window between trade rotations. RK's hyperscale staging team — pre-positioned at our Pinal County, AZ inbound hub — runs the rack staging, the asset-tag audit, and the scheduled deployment by hour. Every rack on the floor when the GC needs it. Every serial accounted for. The buildout schedule moves on the same takt as the construction crew.
Rack-ready staging for a hyperscale data-center buildout.
The customer
A large-scale AI and hyperscale data-center program in the western United States. Server, networking, and power equipment arrive from a mix of global OEMs on compressed lead times. Every deployment window is measured in days — the earlier a rack is live, the sooner capacity generates revenue for the customer.
The challenge
Data-center buildouts fail slowly in supply chain. Servers that arrive damaged, out of sequence, or not pre-configured create cascading delays at the hall. Active construction sites cannot absorb thousands of uncoordinated inbound shipments. The customer needed a partner that could receive gear from multiple OEMs, stage it, verify it, kit it to the rack map, and release it into the site only when the site was ready to receive it.
The RK solution
RK designed a dedicated staging and deployment program: receive and inspect inbound server, networking, power, and structured-cabling equipment from multiple OEMs; stage securely in a high-value-asset area with FTZ handling for imported components; kit per the customer's rack map so what rolls out of RK is ready to slot into the hall; and deliver on a site-scheduled cadence via white-glove transport. A dedicated RK program team runs the operation alongside the customer's deployment leadership.
What changed
The customer stopped receiving uncoordinated OEM shipments at the construction site. Rack deployments happen in the right order, on the right day, with gear that has already been inspected and kitted. Working capital tied up in damaged or mis-sequenced inbound is returned to the program. The customer's deployment team focuses on bringing capacity online — not on solving logistics fires.
“The Control Tower is the first 3PL system we've used where the dashboard is actually current. Sixty-second visibility is real.”

Black Friday hit at 12:01 a.m. Eastern. By the end of the weekend the customer's branded cartons were leaving RK's Patterson and Industrial Way docks at peak rate, with the same-day cutoff held for stocked SKUs and integrated returns processed within 48 hours. Inventory accuracy held at 99.4% trailing-twelve-months. The customer's brand team got their Monday metrics post — and the reverse-logistics queue was already drained.
eCommerce fulfillment & reverse logistics for a connected consumer brand.
The customer
A global connected-products brand selling direct-to-consumer through major eCommerce platforms and through B2B distribution channels. The brand experience is a defining part of the product — from package opening to product return.
The challenge
Two structurally different operations — direct-to-consumer eCommerce and B2B wholesale — were being run by separate vendors on separate systems. Returns and asset recovery were a third silo. Reconciliation, inventory accuracy, and brand consistency were all suffering.
The RK solution
RK consolidated the operation into a single integrated program: B2C eCommerce orders and B2B wholesale orders fulfilled from one inventory pool, in customer-branded packaging, through integrated commerce-platform connections. A structured reverse-logistics workflow handles product recovery, restocking, and certified disposition end-to-end.
What changed
One inventory pool. One reconciliation. One brand experience whether the order came from a wholesale buyer or a consumer's mobile checkout. Returns become a working-capital lever rather than a cost. Internal team headcount returns to product, marketing, and growth — not to managing logistics vendors.
“Our customer's first physical experience of the brand is the box. RK runs the box like it's their brand.”
