The single biggest obstacle to product regulatory compliance isn't the regulations themselves—it's the blind spots companies suffer from below their tier 1 suppliers. While most businesses can get declarations of conformity from their direct suppliers, challenges emerge in tier two, three, and beyond.
For companies managing product regulatory compliance across multiple regions, manually monitoring all the annual changes to key regulations often comes close to being its own full-time job. Unfortunately, few companies can afford a compliance professional dedicated to this demanding task, and regulatory changes often slip through the cracks.
The highly manual, often ad-hoc technique of managing compliance through spreadsheets works fine for a hundred parts. It falls apart, however, when compliance professionals are trying to track their regulatory obligations for thousands of components.
Product regulatory compliance has quietly become one of the more challenging responsibilities for a myriad of U.S. industries. Sectors like technology, automotive, aerospace and defense, and medical devices now strive to comply with more product and material compliance regulations than ever before. Somewhat ironically, though, it’s not necessarily the requirements of the laws themselves that make compliance so arduous in 2026. Rather, it’s the depth and complexity of modern supply chains—and the limited systems many compliance teams possess to track them.
To cite one example, a single printed circuit board assembly (PCBA) might go through a half-dozen or more suppliers before it becomes a final product ready to be shipped to an original equipment manufacturer (OEM) customer. Each of those manufacturing tiers could be subject to different regulatory obligations, including REACH in the EU, RoHS variants in China, and conflict minerals disclosure under Dodd-Frank, among other obligations. Multiply that complex jumble of regulations across a BOM with hundreds or even thousands of line items, and it's easy to see why compliance teams are facing unprecedented challenges right now.
Below we outline five recurring pain points experienced by professionals working in fields that rely on electronic components, while also exploring strategies for addressing—or circumventing—them.
Pain Point One: No Visibility Below Tier One
The single biggest obstacle to product regulatory compliance isn't the regulations themselves—it's the blind spots companies suffer from below their tier 1 suppliers. Most
businesses can get declarations of conformity from their direct suppliers without too much trouble. The challenges emerge in tier two, three, and beyond, however, where smelters, refiners, and subcomponent manufacturers are much harder to reach and obtain consistent answers from. These businesses may not consistently respond to compliance requests, especially when it’s coming from a company they have no direct contractual relationship with.
These obstacles are especially acute for conflict minerals reporting. Tracing tin, tantalum, tungsten, and gold (3TG) back to a smelter requires cooperation from suppliers who often don't know, or won't say, where their own raw materials originated from. The EU's Conflict Minerals Regulation leans on the Responsible Minerals Assurance Process to validate smelters. And while RMAP added recognized smelters in October 2025, the compliance burden of actually chasing that documentation down the chain still falls on the original equipment manufacturers.
Addressing Sub-Tier Blind Spots
Businesses can use component-level compliance databases that already hold manufacturer declarations, RoHS and REACH statuses, and 3TG data. These databases, often included in supply chain risk management (SCRM) software, eliminate much of the need to chase down paperwork at various elusive subtiers. Instead of emailing a supplier and waiting weeks for a reply, compliance teams can leverage these software tools to pull up existing certificate data, helping them quickly flag the parts that are at risk of noncompliance.
Pain Point Two: The Erratic Regulatory Landscape
REACH's Substance of Very High Concern list is one example of a regulatory rule that changes every year, but not necessarily on a predictable schedule. This unpredictability goes beyond REACH and its SVHCs. The past year alone brought new CMR substance entries under REACH Annex XVII, expanded PFAS restrictions with a long implementation runway, and China's updated RoHS standard, GB 26572-2025, which took effect this past August. None of these changes arrived with much advance warning for the average procurement team. Nevertheless, missing one of their compliance deadlines could trigger a regulatory violation, shipment detainment, or other costly disruption.
For companies managing product regulatory compliance across multiple regions—including the EU, China, the U.S., and even individual American states—manually monitoring all the annual changes to key regulations often comes close to being its own full-time job. Unfortunately, few companies can afford a compliance professional dedicated to this demanding task, and regulatory changes often slip through the cracks.
Addressing the Ever-Shifting Regulatory Landscape
Companies able to draw on automated regulatory monitoring tied directly to their bills of materials (BOMs) can streamline these sprawling obligations. With this capability, when a part on an active BOM gets flagged under a newly restricted substance or an expanded regulation, engineering teams find out fast. This type of efficiency allows manufacturers to make adjustments and adapt to regulatory changes before their BOMs go into production.
Pain Point Three: Compliance Requirements Diverge by Industry
Different sectors have different regulatory responsibilities. While some laws, like RoHS, cover all different types of electronic equipment, others have more specific, nuanced scopes. Businesses need to be aware of what directives they do—and do not—fall under. This can be especially difficult for larger manufacturers that produce parts or goods for different industries.
Automotive: Auto manufacturers layer IMDS (International Material Data System) reporting on top of REACH and RoHS. Because of this and other related reasons, they increasingly need visibility into battery and EV-specific material restrictions as electrification accelerates.
Aerospace and Defense: U.S. defense contractors are currently managing NDAA Section 1260H's restrictions on certain Chinese-origin components. In addition, these companies face ITAR and export control classifications that have less to do with substance restrictions than they do with country of origin (COO) and other manufacturing location data.
Medical Technology: Medical device companies are in the middle of the transition to the FDA's Quality System Regulation, which harmonizes US requirements with ISO 13485 and carries a February 2026 compliance deadline. These impending responsibilities will be arriving on top of the EU MDR and EUDAMED reporting obligations.
Consumer Electronics: Brands are watching a growing patchwork of state-level extended producer responsibility laws and packaging regulations being added to existing federal and international rules they already need to track.
Technology Companies: These manufacturers often feed into, or are otherwise connected with, many or most of the sectors outlined above. And because so much of what they build touches many of these downstream industries, their compliance obligations are often the most complicated of all.
Suffice it to say, a generic compliance checklist doesn't work across five industries with five different regulatory postures. Product regulatory compliance now has to be executed at the part level, with rules that reflect the actual end use of the component, rather than a one-size-fits-all template.
Addressing Industry-Level Compliance
Businesses struggling to understand what regulations they fall within the scope of can use compliance tracking tools that let teams filter and flag by end-market and application. These functionalities allow an engineer sourcing a connector for a defense program to see NDAA and ITAR flags front and center. Another engineer sourcing the same connector family for a consumer device, meanwhile, can use this software to see RoHS and state EPR flags instead.
Pain Point Four: Spreadsheets Can't Scale
Even at the more well-resourced organizations, a shocking number of compliance programs still run primarily on spreadsheets. These programs are often organized with one tab per supplier and one column per regulation, and they’re updated whenever someone remembers to cross-reference recent regulatory changes with their own internal spreadsheets.
This highly manual, often ad-hoc technique works fine for a hundred parts. It falls apart, however, when compliance professionals are trying to track their regulatory obligations for thousands of components. These breakdowns often happen when companies can least afford it: during a customer audit, an RFQ compliance attestation, or a scramble to requalify parts after a substance ban takes effect.
Moreover, spreadsheets don't talk to procurement systems, engineering BOMs, or one another. A substance restriction discovered by the compliance team doesn't automatically reach the engineer who's about to incorporate that same part into a new product. Instead, communicating spreadsheet updates across a company is yet another manual responsibility, one vulnerable to the same whims and inconsistencies as the regulatory updates themselves.
How to Address Spreadsheet Compliance
Consolidating all compliance data alongside part risk data—including lifecycle status, sourcing risk, and regulatory status—creates a centralized location to assess the many different manifestations of part risk. It also means that all relevant information moves with the part, not with whoever happened to update a file last.
Pain Point Five: Compliance Statuses Don’t Survive Part Substitutions
Obsolescence and shortages force part substitutions all the time in the electronic component supply chain. Every one of those innumerable swaps quietly resets the compliance clock. A replacement part from a different manufacturer—or even a new date code from the same manufacturer—can carry a different RoHS certificate, a different REACH declaration, or a different country of origin entirely (these differences are especially consequential for anything impacted by NDAA or ITAR restrictions).
The problem is that lifecycle management and compliance tracking usually live in separate systems, if they're tracked formally at all. An engineer swaps in a cross-reference part to solve an availability problem, the design moves forward, and nobody circles back to confirm that the replacement carries the same compliance status as the part it replaced. And when that data gap does surface, it’s often at a highly inconvenient time.
Addressing Compliance Status Update Issues
Organizations should implement a system in which a substitution automatically triggers a compliance check, rather than relying on manual due diligence every time engineering teams bring in a cross-reference. If a proposed replacement part doesn't match the RoHS, REACH, or conflict minerals status of the original, that should get flagged before the BOM is finalized and the item goes into production.
Standardizing Product Regulatory Compliance
If there’s one consistent thread across all the above pain points, it’s that the solutions are not particularly onerous. They just require a different mindset, one that stops treating compliance as a document-collection exercise and understands it as a data problem requiring the same diligence and rigor applied to part availability, cost, or supplier risk.
