The Packaging and Packaging Waste Regulation (PPWR), Regulation (EU) 2025/40, which applies generally from 12 August 2026, classifies packaging on three separate axes: structural level, functional subtype and lifecycle status. A single unit, like an e-commerce mailer or a takeaway cup, gets a separate answer on each axis, and all three apply at once. For the full breakdown of every axis, article number and legacy equivalent, download the PPWR packaging classification chart here.

Legacy labels don't map cleanly onto PPWR

Most packaging and compliance teams still think in primary, secondary and tertiary packaging. Those terms come from the old Packaging and Packaging Waste Directive, which PPWR repeals and replaces. PPWR's own Article 3 definitions use different names for the same rough tiers, and the mapping is close but not exact:

• Sales packaging (Article 3(1)(5)): the unit supplied to the end user at the point of sale, together with the product. Roughly equivalent to primary packaging.
• Grouped packaging (Article 3(1)(6)): a grouping of a number of sales units at the point of sale, removable without affecting the product's characteristics. Roughly equivalent to secondary packaging.
• Transport packaging (Article 3(1)(7)): facilitates handling or transport of sales units or groupings to prevent damage, excluding containers used for transport by road, rail, ship or air. Roughly equivalent to tertiary packaging.

Relabelling instead of reclassifying is the most common failure mode here. A team that swaps secondary for grouped on existing records will miss every case where the old category doesn't translate cleanly, and PPWR gives no credit for using the right vocabulary if the underlying classification is wrong.

One wrong classification cascades further than it looks

Structural level and functional subtype together determine which obligations apply to a packaging unit, so a misclassification rarely stays contained to a single line item. Article 24 sets a maximum 50 percent empty space ratio for grouped, transport and e-commerce packaging from 1 January 2030, a rule that doesn't apply the same way to plain sales packaging. A unit classified as sales packaging when it should have been transport packaging, or the other way round, can put a team out of step with a requirement it didn't know applied. Lifecycle status carries its own version of this problem: PPWR requires manufacturers to retain technical documentation for five years, or ten years if the packaging is reusable.

The three questions PPWR asks about every packaging unit

Every packaging unit gets run through the same three axes: one mutually exclusive, one conditional and one that applies regardless of the other two.

What structural level is it?

This is Axis 1. Every packaging unit gets exactly one answer: sales packaging, grouped packaging or transport packaging, as defined above.

Does it carry a functional subtype?

Axis 2 sits underneath a structural level and only applies where PPWR names a specific use case:

• E-commerce packaging (Article 3(1)(8)): transport packaging used to deliver products in online or other distance sales to the end user.
• Service packaging (Article 3(1)(1)(d)): sales packaging designed and intended to be filled at the point of sale to dispense a product, such as a bakery bag.
• Take-away packaging (Article 3(1)(3)): service packaging filled at an attended point of sale with beverages or ready-prepared food, packaged for transport and immediate consumption elsewhere.
• Primary production packaging (Article 3(1)(4)): sales packaging designed for unprocessed primary-production products.

A unit can have zero functional subtypes, plain grouped packaging around a multipack is a common example, or exactly one. It never has more than one, since each subtype nests under a single structural level.

Is it reusable or single-use?

Reusable packaging has no standalone Article 3 definition. Article 11(1) sets the criteria instead: the packaging must be conceived, designed and placed on the market to be reused multiple times, designed for the maximum number of rotations, and capable of being emptied or reconditioned per Annex VI while remaining functional. Single-use packaging (Article 3(1)(28)) is defined negatively, as anything that isn't reusable packaging.

From 1 January 2030, PPWR requires at least 40 percent of certain transport packaging, including formats used in e-commerce such as pallets, boxes, crates and pallet wrapping, to be reusable within a re-use system, rising to a 70 percent target by 2040. A transport packaging unit that should be flagged reusable but isn't will misreport against that target from day one.

All three axes above are mapped in full, alongside every article number and legacy equivalent, in the downloadable PPWR packaging classification reference chart.

Classifying a packaging unit in practice

Work through the axes in sequence rather than trying to answer all three at once.

• Identify the structural level first. Is it sales, grouped or transport packaging? This answer is mutually exclusive.
• Check for a nested functional subtype. Does PPWR name a specific use case for this structural level: e-commerce, service, take-away or primary production?
• Apply the lifecycle overlay. Regardless of the first two answers, is the unit reusable under the Article 11(1) criteria, or single-use by default?

Example: a takeaway coffee cup

Structural level: sales packaging, since it's the unit handed to the end user. Functional subtype: take-away packaging, filled at an attended point of sale for immediate consumption elsewhere. Lifecycle: almost always single-use, unless it's part of a deposit-return cup scheme designed for multiple rotations.

Example: an e-commerce mailer box

Structural level: transport packaging, since it protects the product in transit. Functional subtype: e-commerce packaging, because it's used to deliver a product sold online directly to the end user. Lifecycle: could go either way. A standard corrugated mailer is typically single-use, while a padded, returnable mailer bag designed for repeat use would need to meet the Article 11(1) criteria before it counts as reusable.

Two classifications people get wrong

• Isn't grouped packaging just secondary packaging? Close, but grouped packaging is defined by function, grouping sales units in a way that's removable without affecting them, not by its position in a three-tier hierarchy. Packaging that looks secondary by habit, like shrink wrap that also carries a label or protective function, is worth a second look.
• Is reusable packaging its own structural category? No. It's tempting to treat reusable as a fourth structural level alongside sales, grouped and transport, but PPWR treats it as a lifecycle overlay under Article 11(1) that can apply to any of the three. A reusable unit is still classified as sales, grouped or transport packaging first, and reusable second.

Frequently asked questions

1. Is e-commerce packaging the same as transport packaging?

Legally, e-commerce packaging is a subtype of transport packaging (Article 3(1)(8)), not a separate structural category. It inherits transport packaging's obligations and adds its own on top, including the Article 24 empty space limit that applies from 2030.

2. Is reusable packaging its own PPWR category?

No. Reusable and single-use status is a lifecycle classification under Article 11(1) that applies on top of any structural level. A reusable packaging unit is still first classified as sales, grouped or transport packaging.

3. What's the difference between grouped and transport packaging?

Grouped packaging (Article 3(1)(6)) bundles sales units together and can be removed without affecting them, such as shrink wrap around a multipack. Transport packaging (Article 3(1)(7)) protects sales units or groupings during handling and transport, and specifically excludes containers used for transport by road, rail, ship or air.

4. Is service packaging always sales packaging?

Yes. Service packaging (Article 3(1)(1)(d)) is a subtype of sales packaging, specifically an item designed and intended to be filled at the point of sale to dispense a product.

5. What's the fastest way to audit my packaging classification?

Pick one product line and run every packaging component it uses through the three-axis checklist above: structural level, functional subtype, lifecycle status. Keep the downloadable reference chart next to you while you do it, and note anywhere your team's existing primary, secondary or tertiary labels disagree with the PPWR classification. That gap is where reporting, EPR fee allocation and reuse-target tracking are most likely to break first. If you're mapping classification against declarations of conformity or roles under PPWR, the guide to the PPWR Declaration of Conformity and PPWR roles explained cover the next steps. Coolset's PPWR module tracks classification at the packaging-unit level, so the axis a unit sits on doesn't have to live in a separate spreadsheet from its compliance status.
