Field notes from regulated hardware.
Engineer-led answers to the regulatory questions that slow product development. Specific clauses. Real timelines. No marketing.

What does the EU TPD require to notify an e-cigarette before it can go on sale?
Before an e-cigarette or refill container can be sold in the EU, its manufacturer or importer must notify each member state's competent authority through the EU Common Entry Gate (EU-CEG), six months before placing it on the market. The notification is a structured dossier — ingredients, emissions, toxicological data, nicotine dosing, device design, and the production process. It is not an approval. The six-month standstill, data completeness, and product limits are the real gates.

What does the EU Battery Regulation require, and what's actually due by 2027?
The EU Battery Regulation (Regulation (EU) 2023/1542) has applied since 18 February 2024, but its headline obligations phase in by battery type through delegated acts — several of which have slipped. The carbon-footprint declaration for industrial batteries began on 18 February 2026, the digital battery passport becomes mandatory on 18 February 2027 for EV, industrial (over 2 kWh) and light-means-of-transport batteries, and binding supply-chain due diligence was postponed to 18 August 2027.

How realistic is your EU MDR transition by the 2027 and 2028 deadlines?
Under Regulation (EU) 2023/607, legacy MDD devices must complete their MDR transition by 31 December 2027 for Class III and Class IIb implantables, and 31 December 2028 for other Class IIb, IIa and I devices — but only if you met the 2024 notified-body milestones. With notified-body review running 13 to 18 months and capacity tight, a Class III or implantable manufacturer without an active, progressing application by mid-2026 is at real risk of missing the 2027 date.

What gets a PMTA refused at FDA's acceptance and filing review?
Most PMTAs that fail early never reach a scientist. FDA runs two completeness gates before substantive review: an acceptance review for format and administrative completeness, and a filing review for whether the application holds enough information to evaluate. A missing environmental assessment, absent labeling, no literature search, or — from 2 January 2026 — the wrong submission forms can trigger a refuse-to-accept or refuse-to-file letter before the science is read.

Which EU Cyber Resilience Act conformity assessment route does my product need?
Most products self-assess. The CRA's default category — the large majority of products with digital elements, widely estimated at around 90% — uses internal self-assessment (Module A), with no external body involved. Products listed as important (Annex III) or critical (Annex IV) face stricter routes, and several require a notified body. The catch in mid-2026: the harmonised standards and notified bodies those routes depend on do not exist yet.

What documentation does FDA Section 524B actually require in a premarket submission?
If your device runs software, connects to a network, and could be exposed to cyber threats, Section 524B applies — and an incomplete submission can be refused before review even starts. The FDA's June 2025 final guidance expects five documentation elements: a secure development framework, a threat model and risk assessment, security architecture views, a machine-readable SBOM, and cybersecurity testing evidence.

When does the EU Digital Product Passport actually apply to consumer electronics, and what does the 19 July 2026 registry launch mean for manufacturers?
The EU Digital Product Passport (DPP) registry becomes operational on 19 July 2026 under the Ecodesign for Sustainable Products Regulation (Regulation (EU) 2024/1781). Registry launch is not the same as a product DPP becoming mandatory: the registry is the EU-wide infrastructure that holds unique identifiers and commodity codes, while DPP obligations attach product family by product family via separate delegated acts. For consumer electronics, the first wave reaches the mobile-phone, tablet and cordless-phone ecodesign rule already in force from 20 June 2025; broader consumer electronics DPP obligations are expected from 2027 onward.

What changes for consumer electronics manufacturers when the EU Right to Repair Directive applies from 31 July 2026?
The EU Right to Repair Directive (Directive (EU) 2024/1799) applies from 31 July 2026. Manufacturers of Annex II products — washing machines, refrigerators, vacuum cleaners, electronic displays, mobile phones, slate tablets, cordless phones, servers, data-storage products, and goods with light-transport batteries — must repair on request at reasonable time and price, provide spare parts and repair information, and accept a 12-month extension of the legal guarantee whenever a consumer chooses repair over replacement. The obligation covers your installed base.

How long does a 510(k) submission actually take in 2026, and what's slowing it down?
The FDA's MDUFA V goal is a 90-day decision on 510(k) submissions, met 95% of the time on FDA's clock. The real-world average is closer to 164 FDA days, and the calendar gap to clearance often runs 6–9 months. The single biggest delay is the Additional Information request, which pauses the clock and gives sponsors 180 days to respond. In 2026, QMSR enforcement, rising volumes, and AI/ML device complexity are widening the gap.

What does the EU Cyber Resilience Act's September 2026 reporting obligation require from manufacturers?
Starting 11 September 2026, manufacturers of products with digital elements sold into the EU must report actively exploited vulnerabilities and severe incidents to ENISA on a strict three-step timeline: 24 hours, 72 hours, 14 days. Here's what that means operationally.
