TintedSun brings a rare blend of engineering insight and sourcing strategy to supply chain management. With direct experience leading purchasing, logistics, and material control in the EMS industry, we understand how data, lead times, tariffs, and supplier performance converge to shape real-world outcomes.
Our consulting focuses on building resilient, transparent, and cost-efficient supply chains — from vendor qualification and tariff analysis to inventory optimization and risk mitigation. We don’t just analyze numbers; we strengthen the systems and relationships that keep production moving.

Tariffs can quietly erode margins and disrupt supply chain strategies if not properly managed.
TintedSun helps OEM and EMS organizations identify, track, and mitigate tariff exposure across their bills of materials. We analyze HTS classifications, sourcing geography, and part-level cost structures to uncover hidden expenses and clarify how trade regulations affect true landed cost.
In the electronics industry, a single assembly can include components with multiple countries of origin, each carrying its own duty rate and compliance obligation. TintedSun provides tools and methodologies to map, model, and forecast these layered tariffs — allowing teams to estimate total cost impact early in the quoting process.
Our process delivers actionable intelligence on reclassification opportunities, alternate sourcing strategies, and cost modeling scenarios that maintain competitiveness without compromising compliance—building a more resilient, transparent, and cost-aware supply chain ready to adapt as global trade conditions evolve.

Stagnant inventory ties up cash flow, consumes space, and hides risk inside your balance sheet. TintedSun helps manufacturers evaluate and reduce excess or slow-moving inventory through strategic analysis, process redesign, and market recovery opportunities.
We assess your ERP data, purchasing trends, and demand signals to identify where overstock originates — and design practical systems to prevent recurrence. When liquidation or reallocation is the best route, we connect you with vetted resale or repurposing channels that preserve maximum asset value.
Our approach blends operational understanding with financial awareness, helping you reclaim capital, free up warehouse capacity, and stabilize your material flow.

Need to qualify a new supplier but lack the bandwidth for a formal audit? TintedSun provides independent, third-party vendor assessments grounded in ISO 9001 and AS9100 standards.
Our approach goes beyond checklist audits — we focus on real-world capability, consistency, and reliability. We evaluate a supplier’s quality systems, process controls, and organizational maturity to ensure they meet your technical, regulatory, and delivery expectations. Audits can include on-site reviews, documentation verification, and key team interviews to assess culture, traceability, and responsiveness.
For electronics manufacturers, we also review ESD programs, material traceability, and process validation controls to ensure alignment with the demands of high-reliability PCB and assembly production. These deeper insights help prevent costly escapes and strengthen supplier relationships.
Whether you’re onboarding a new manufacturing partner or revalidating an existing vendor, our audit process delivers objective insights that drive confident sourcing decisions and long-term supply chain performance.
