The classic stages of new product development are: idea, screening, concept, business case, development, validation, launch. In 2026 a physical product sold in the EU also carries legal obligations on its label, its packaging, its online listing and its after-sales life. Several of those obligations started to apply in the last few months. The US tariff framework changed legal basis twice in the same period.
This article walks through each stage with the risks that matter now for manufacturers of physical goods. It is written for product managers, compliance leads and operations teams who already know the textbook model and need to know where it breaks.
Key Takeaways
- Compliance data now has to be defined in the concept and development stages. Retrofitting it at launch is where most delays come from.
- Four EU rule sets changed the late stages of development in 2026: the unsold goods destruction ban (July), the Right to Repair Directive (July), the Packaging and Packaging Waste Regulation (August) and the green claims rules (September). The Digital Product Passport follows from February 2027 for batteries.
- Landed cost is a moving target. Business cases for imported components need tariff scenarios, and HS codes and country of origin need to sit in the product record from the start.
- The post-launch phase is now a formal stage of development. Repair obligations, spare parts and passport updates keep the product record active for years.
What Changed For Physical Products In 2026
A short timeline explains why the late stages of development got heavier this year.
On 19 July 2026, large companies in the EU lost the right to destroy unsold clothing, accessories and footwear. Medium-sized companies follow in 2030 (European Commission).
On 31 July 2026, the Right to Repair Directive started to apply. Manufacturers of covered goods such as household appliances, phones and tablets must offer repair after the legal guarantee expires. A consumer who chooses repair gets a one-year guarantee extension. The list of covered products will grow each year.
On 12 August 2026, the Packaging and Packaging Waste Regulation (PPWR) became directly applicable. Each packaging type now needs an EU Declaration of Conformity and supporting technical documentation.
On 27 September 2026, the green claims rules of the Directive on Empowering Consumers for the Green Transition started to apply. Vague environmental claims without verifiable evidence are prohibited in B2C communication. Existing products get no transition period.
The Digital Product Passport (DPP) comes next. The Commission's indicative timeline makes passports mandatory for EV, light transport and industrial batteries from 18 February 2027. Delegated acts for iron and steel are expected in late 2026, and for textiles, aluminium and tyres in 2027. Each delegated act comes with a transition period of at least 18 months.
In the US, the Supreme Court ruled in February 2026 that IEEPA does not allow the President to impose tariffs. The replacement 10% surcharge under Section 122 was challenged in court and set to expire in July, and other tariff authorities remain available. So the duty rate at launch may differ from the rate in the business case.
None of these rules sits in one department. Each one lands on a different stage of development, and each one needs structured product data.
Stage 1: Idea Generation
Ideas for physical products in 2026 come from three places more than before: customer feedback at scale, regulatory change and supply disruption.
Customer feedback is now machine-readable. McKinsey describes consumer companies using LLM tools to synthesise product reviews, social posts and service transcripts to find unmet needs and underserved segments. Return reasons and warranty claims belong in the same pool. They are the cheapest source of improvement ideas a manufacturer has, and they already exist in the ERP and service systems.
Regulation generates ideas too. A repair obligation makes a modular design worth more. A packaging rule makes a refill format or a lighter pack worth evaluating. A tariff on a component category makes an alternative material or a second supplier region a product decision.
Log every idea with its origin. An idea that came from a regulatory change carries a deadline. An idea from return data carries a baseline you can measure against after launch.
Stage 2: Idea Screening
Screening kills ideas cheaply. The usual filters are market fit, technical feasibility, strategic fit, and rough margin. In 2026, add a compliance filter with three questions: which EU and target-market rules apply to this product category, which of them change in the next three years, and what data will the product need to carry to comply.
The third question is where screening usually fails. A team approves a product concept for the EU market and learns in the development stage that it falls under a delegated act due in 2027, or that its packaging needs a Declaration of Conformity and a PFAS test report. The concept survives. The launch date does not.
Screening should also flag products that will stay on the market long enough to hit later deadlines. A product launched in 2026 with a seven-year lifecycle will live through the PPWR recyclability requirements in 2030 and possibly through a DPP requirement for its category.
Stage 3: Concept Development And Testing
Concept development turns an idea into a defined proposition: target customer, core benefit, key specifications, price range, and positioning. Concept testing checks whether customers want it.
Generative AI made the early concept loop much faster. McKinsey reports cases where AI tools used across the design lifecycle cut product development cycle times by upward of 70%, freeing time for consumer testing, supplier vetting and design for manufacturability. The same source is clear that the tools help designers iterate and do not replace judgment on what to build.
Faster concepts create a new risk. Teams test more variants, and the number of candidate attributes grows fast. Without a shared attribute model, each concept document describes the product in its own terms, and the specifications that reach engineering are inconsistent.
The positioning statement needs a legal check at this stage. From 27 September 2026, generic claims such as "green" or "eco-friendly" need recognised excellent environmental performance behind them, and sustainability labels must come from a public authority or a certification scheme that meets the directive's requirements (Cooley). The Commission's FAQ states that brand and product names can count as environmental claims if they convey an environmental message, even when they are protected trademarks.
A product name with "eco" in it is a legal decision in 2026. Make it in the concept stage, before packaging artwork, domain names, and trademark filings depend on it.
Stage 4: Business Analysis
The business case estimates volume, price, cost, and margin over the lifecycle. For physical products, three cost lines became harder to estimate this year.
Landed cost is the first. The US tariff regime changed legal basis twice between February and July 2026, and Sections 232 and 301 remain available for new measures. A single-point tariff assumption in a business case is a guess. Run at least three scenarios for each major imported component, and store the HS code and country of origin for every component in the product record. Tariff exposure then becomes a query, and it stops being a spreadsheet exercise repeated for each product.
Compliance cost is the second. It now includes packaging conformity documentation, EPR registration and fees per country, third-party verification for any environmental claim, and later the cost of creating and hosting passport data.
Lifecycle cost is the third. Repair obligations mean spare parts stock, repair documentation, and service capacity for years after the last unit ships. For apparel, footwear and accessories sold by large companies in the EU, destroying overstock is no longer an option. The forecast error that used to end in a write-off now ends in discounting, donation, or reuse channels, each with its own margin impact.
A business case that leaves out these three lines will look better than the product it describes.
Stage 5: Product Development And Engineering
This is the longest stage and the one where most product data is created. Engineering produces the bill of materials, drawings, material specifications, test plans, and supplier selections. Design for manufacturability and design for cost are standard. In 2026, add design for repair, design for recyclability, and design for documentation.
Design for repair means fasteners over adhesives where possible, standard parts, accessible batteries and a spare parts list defined before tooling. The repair obligation turns spare parts availability into a compliance question, so the parts catalogue has to exist at launch, with part numbers, compatibility data and exploded views.
Design for recyclability starts with packaging. PPWR phases in design-for-recyclability requirements from 2030 and requires packaging to be recyclable at scale from 2035 (Latham & Watkins). A pack designed in 2026 for a product with a long lifecycle will face those rules. Packaging placed on the EU market must also carry traceability data such as a type, batch, or serial number (reuschlaw).
Design for documentation is the least familiar of the three. It means the team decides during engineering which data points the product will need to prove compliance and publish downstream, and it assigns an owner and a source to each. For a product in a DPP category, that list covers material composition, recycled content, substances of concern, repair information, and a unique product identifier. Most of this data comes from suppliers. Supplier questionnaires take months, so the request has to go out when suppliers are selected and before production starts.
Our customers turn to us with a recurring version of this problem. Engineering holds the BOM and material data in PLM or ERP. Compliance keeps certificates and test reports in shared folders. Marketing writes product copy in a separate system or in spreadsheets. When a retailer or an authority asks for the recycled content of a specific variant with evidence, three teams spend days reconciling three versions of the product. In projects we implemented, the fix was to agree on one attribute model for the product family during development, link each compliance attribute to its evidence document, and let each system keep its own job. PLM stays the source of engineering truth. A PIM system becomes the place where engineering, compliance and marketing data meet, get checked for completeness and get published.
Every compliance attribute needs three things: a value, a source document, and an owner. If one of them is missing at the end of development, the attribute will be missing at launch.
Engineering changes are the second data risk in this stage. A material substitution made to cut cost or avoid a tariff can invalidate a test report, a recycled content figure, or an environmental claim. Change control needs a check that flags which downstream attributes and documents each change affects.
Stage 6: Validation And Test Marketing
Validation covers prototype testing, certification, pilot production and, where it makes sense, a limited market test. For many B2B and industrial products, a full test market is impractical, and validation relies on pilot customers and field trials.
Certification is where schedule risk concentrates. Test labs are booked in advance, and a failed test sends the product back to engineering. Test reports feed the technical documentation required under the General Product Safety Regulation (GPSR) and under product-specific legislation such as the Toy Safety Regulation or the Radio Equipment Directive.
Market surveillance got more active. EU authorities issued 4,671 Safety Gate alerts in 2025, the highest number on record and 13% more than in 2024. Cosmetics and toys made up more than half. The Commission's eSurveillance webcrawler scanned over 1.6 million websites in 2025 and found more than 20,800 listings of products already flagged in Safety Gate. A coordinated online sweep for GPSR compliance is planned for 2026.
Pilot runs should test the data as well as the product. Publish the pilot product to one channel with the full data set and check what arrives: images, warnings, manufacturer details, identifiers, and translations. Errors found here cost minutes. The same errors found after launch across ten marketplaces cost weeks.
Stage 7: Commercialization And Launch
Launch is where product data leaves the company. Every channel gets its own copy: the brand website, distributor portals, retailer onboarding templates, marketplaces, printed catalogues and, soon, the DPP data carrier on the product.
Legal minimums for online listings are already in force. Under GPSR Article 19, every distance-selling offer must show the manufacturer's name and postal and electronic address, an EU economic operator where the manufacturer is outside the EU, product images and type information, and warnings or safety information in a language consumers understand (Fieldfisher). The same warnings must appear on the product, the packaging, or an accompanying document. A manufacturer that supplies incomplete data to distributors pushes the compliance gap onto every listing they create.
Content quality also affects returns. In Syndigo's 2025 consumer study, 21% of respondents globally had returned a product that did not meet expectations set by its content, and the figure for US respondents was 31%. For apparel sold by large companies in the EU, returned and unsold stock can no longer simply be destroyed, so returns caused by bad content carry a longer tail.
A launch data checklist for EU physical products in 2026 looks like this:
- GPSR listing data: manufacturer and EU responsible person contacts, product identifiers, images, warnings in each target language.
- Packaging data: Declaration of Conformity per packaging type, traceability identifier, EPR registration per country, PFAS evidence for food-contact packaging.
- Claims data: each environmental claim linked to its certificate or evidence, with the claim text approved per language.
- After-sales data: spare parts list, repair information, legal guarantee information and, for products in scope, the data needed for the future passport.
Channel formats differ, and they change. Retailers update onboarding templates, marketplaces add mandatory fields, and industry classifications such as ETIM or GS1 release new versions. Mapping one internal product model to many outputs is the core job of a PIM system. Tools like AtroPIM, an open-source PIM built on the AtroCore data platform, handle this by holding a configurable data model with completeness checks and pushing channel-specific exports through an API. The choice of tool matters less than the principle: one maintained product record, many generated outputs, and no manual re-keying at launch.
Launch timing needs one more check. The green claims rules apply to old stock too, so a product launched with packaging printed months ago must still comply with the rules in force on the day it is sold.
Stage 8: Post-Launch Lifecycle Management
Textbooks often end the stages of new product development at launch. For physical products in the EU, the post-launch phase now carries its own obligations and should be planned as a stage with its own gates.
Repair requests arrive after the legal guarantee ends. Each repair extends the guarantee, so repair records need to be tied to the unit or batch. Spare parts need part numbers, compatibility data, and availability status that service partners can look up.
Passport data will need maintenance. A DPP is tied to a unique product identifier and has to stay accessible and accurate while the product is on the market. When a supplier changes, when a material changes, or when a delegated act adds a field, the passport data changes with it.
Unsold goods need a disclosure trail. Large and medium companies that discard unsold consumer products must report the numbers, reasons, and methods, and for apparel, footwear, and accessories, large companies must use one of the defined derogations to justify any destruction. Claims need monitoring. A certificate that expires or a supplier that loses its certification can make an existing claim unlawful overnight.
Launch is the start of the longest phase of the product record. Budget people and systems for it as you would for development.
Feedback from this stage closes the loop to Stage 1. Return reasons, repair frequency by component, and spare parts demand are the best inputs for the next generation of the product.
Where Product Data Breaks Between Stages
Most delays in physical product development in 2026 trace back to handoffs. Each stage produces data in a different tool, and each handoff is a chance to lose or distort it.
Concept documents describe attributes in free text. Engineering converts them into specifications in PLM. Compliance attaches evidence in a document management system. Marketing rewrites everything for customers. Sales teams export spreadsheets for distributors. By launch, a single product exists in five versions, and nobody can say which one an authority or a retailer should trust.
The practical fixes are unglamorous. Define the attribute model for a product family before development starts. Give each attribute one owner. Store evidence next to the value it supports. Set completeness rules per channel and per market, so the system blocks publication when a required field is empty. Connect the systems that create data to the system that distributes it, and stop copying.
This is the niche where PIM software fits in the development process. It does not replace PLM, ERP, or a compliance tool. It becomes the layer where their data meets and gets checked before it goes out. Manufacturers with a few dozen products and one sales channel can often manage with disciplined spreadsheets. The case for a PIM system grows with the number of variants, languages, channels, and regulated attributes, and in 2026 the regulated attributes grew for almost everyone selling physical goods into the EU.
A realistic trade-off: introducing a PIM system during an active launch adds work in the short term. Data has to be modelled, migrated, and cleaned. Teams that start with one product family in the development stage, and extend the model family by family, usually see results sooner than teams that attempt a full catalogue migration before a deadline.
The stages of new product development have not changed in name. What changed is that each stage now produces data that someone outside the company will check. Plan the data with the product, and the later stages get shorter.
