PU | Code | Full name | Definition (one sentence) | Notes / where used | | --- | --- | --- | --- | | DLC | Data Life Cycle | Tracks the informational status of a Supply Chain Unit record per system or data channel. | Triple Life Cycle terminology | | DRU | Deposit Return Unit | A Disposal Unit that is intended to be returned via a deposit scheme. | EPR context (Deposit) | | DRS | Deposit Return System | The deposit scheme and operating system through which Deposit Return Units are returned and managed. | EPR context (Deposit) | | DU | Disposal Unit | A combination of Packaging Elements that is disposed of together (for example, a bottle disposed with labels attached). | EPR context (disposal modelling) | | GP | Grouped Packaging | Additional packaging used to bundle multiple ISUs into a GSU. | Packaging role | | GSU | Grouped Sales Unit | A commercial multi-pack created by bundling multiple ISUs with additional Grouped Packaging. | Supply Chain Unit (SCU) | | ISU | Individual Sales Unit | The sellable unit created by combining the Product with its Sales Packaging. | Supply Chain Unit (SCU) | | MPS | Master Packaging System | The unique combination of Packaging Masters that defines a packaging system configuration. | Packaging system modelling | | PAU | Packaging Assembly Unit | A specific assembled/finished packaging variant (often decoration or print specific) based on a Packaging Master. | Example: decorated label variant based on a white-label PM | | PCU | Product Core Unit | The final produced product unit before packaging, which becomes an ISU when combined with Sales Packaging. | Product to Sales Unit transition | | PE | Packaging Element | An individual packaging component that can be combined into larger packaging constructs such as a DU or SCU level. | Packaging structure modelling | | PIU | Product Intermediate Unit | A produced intermediate product unit that is used as an input for another product unit and is not yet packed as an ISU. | Product structure modelling | | PM | Packaging Master | A technical packaging element template that can have multiple PAUs derived from it. | Example: “white label with dieline” as the base PM | | PMU | Product Material Unit | A product material that is sourced or specified as an input for product production. | Product structure modelling | | SCH | Supply Chain Hierarchy | The full hierarchy setup from the highest SCU downwards, including packaging elements at each level (for example Pallet TSU, Case TSU, GSU, ISU plus PEs). | Portfolio and packaging modelling | | SCU | Supply Chain Unit | The group term for units handled through the supply chain, covering ISU, GSU, and TSU (for example ISU in retail store, TSU in distribution centre). | Grouping concept for ISU/GSU/TSU | | SLC | Supply Life Cycle | Tracks the physical existence stages of a Supply Chain Unit. | Triple Life Cycle terminology | | SP | Sales Packaging | Packaging components required to create the smallest sellable unit (the ISU). | Packaging role | | TAU | Throw Away Unit | A Disposal Unit that is intended to be discarded (not returned via a deposit scheme). | EPR context (non-deposit disposal) | | TLC | Trade Life Cycle | Tracks the commercial availability stages of a Sales Unit per market or channel. | Triple Life Cycle terminology | | TP | Transport Packaging | Additional packaging used to create a TSU for shipping and storage. | Packaging role | | TSU | Transport Stock Unit | A logistics unit created by combining multiple ISUs and/or GSUs with additional Transport Packaging. | Supply Chain Unit (SCU) | | UOP | Unit of Packaging | A Unit of Packaging is the combination of Packaging Elements as one unit for identification, assessment, or regulatory evaluation, for example a sales, grouped, or transport packaging unit. | Example: A Bottle with cap, a front and back label is one packaging unit. |   -
