What Are the Most Common Packaging Challenges in Mergers and Acquisitions?

The day you put your own logo on an acquired product, you become legally responsible for packaging you have almost certainly never seen the paperwork for. This does not come up in the deal room. It comes up in week three, when someone asks where the technical file for a particular carton is and the answer turns out to be a converter whose contract ended at close.

The most common packaging challenges in mergers and acquisitions are inherited compliance liability, approved artwork held by third parties, duplicate pack specifications, harmonizing regulatory copy across two portfolios, transferring extended producer responsibility registrations, and consolidating print suppliers. The unfortunate part is, almost all of them surface after close, when the integration clock is already running – but the good news is, there are ways to get ahead.

Who is Responsible For Packaging Compliance After an Acquisition?

Under the PPWR, the practical test for who counts as the manufacturer is whose brand appears on the packaging. If it is yours, the obligation to sign the Declaration of Conformity and hold the supporting technical documentation is yours, and you are the party auditable by market authorities. That responsibility stays with you even where a supplier or converter carried out the conformity assessment and prepared the file.

This matters at the exact moment an acquisition becomes visible on shelf. The day you rebrand an acquired product, you become the manufacturer of its packaging for PPWR purposes and inherit the evidence burden for it – every substance test result, recycled content claim, and material breakdown behind the declaration.

Most packaging diligence checklists were written before August 2026 and ask about volumes, formats, and supplier contracts. Very few ask to see the technical documentation. If it does not exist, or exists only in fragments across the seller's supply chain, you find out after you own it.

Where is Approved Packaging Artwork Actually Stored?

In most regulated manufacturers, print-ready artwork sits with design agencies, repro houses, and printers, and the acquired business holds reference PDFs rather than editable source files.

The contracts holding those relationships together frequently terminate at close. So the practical position on day one is that you own a SKU list, a set of flat PDFs, and no working files – while the people who can produce a corrected pack are no longer engaged. Establishing where every approved asset physically lives, and who has the right to release it, is worth doing during diligence rather than during your first regulatory change.

What Happens to Duplicate SKUs and Pack Specifications?

Portfolio rationalization gets treated as a commercial decision, but it is a data problem first. After close you hold two pack format libraries, two sets of dielines, two substrate specification systems, and two symbol libraries – and the two sides describe the same physical pack in incompatible terms.

You cannot rationalize what you cannot compare. Before anyone can decide which of two near-identical cartons survives, someone has to establish that they are near-identical, which means normalizing two specification vocabularies into one. That work is unglamorous, sits on the critical path for every synergy target attached to packaging, and is almost never scoped.

How Do You Harmonize Regulatory Copy Across Two Portfolios?

Harmonization is usually framed as process and culture alignment. In packaging it is narrower and considerably more expensive: two companies phrase the same warning differently, hold different translation sets, use different symbol conventions, and make subtly different claims about equivalent products.

Someone has to decide which version wins, per phrase, per market. That is a regulatory decision, repeated at scale, and it needs regulatory affairs sign-off rather than design sign-off. Teams that treat it as a branding exercise discover the difference at the first audit.

Do EPR Registrations Transfer When a Brand Changes Hands?

Extended producer responsibility registrations are held by a registered producer entity in each member state, not by the brand. A change of ownership generally requires action in every market where the packaging is placed, rather than transferring automatically with the asset.

The gap between close and completed re-registration is the exposure. Product continues moving; the obligation to report and pay against it has to sit with somebody, and transition service agreements do not always say clearly which somebody.

What Changes in a Divestiture or Carve-Out?

Everything above, run in reverse and under a harder deadline. You are stripping your identity off packs you no longer own while assembling artwork packages for a buyer, against a transition services clock set during negotiation rather than by anyone who has done a packaging migration.

Divestitures also expose asset custody faster than acquisitions do. You cannot hand over what you cannot locate, and the discovery that a printer holds your only editable file for a divested brand tends to arrive late.

Where the Obligations Sit

Getting ahead of it

The pattern across all six is the same: packaging obligations are attached to data that no one has consolidated, and the deal timetable assumes that consolidation is quick. It is quick only where a single source of truth already exists.

Kallik's Veraciti™ platform is built for exactly this position – bringing artwork, specifications, and regulatory content into one governed system so that a change of ownership becomes a data operation rather than a rebuild.
