Country-specific packaging variants: Requirements for planning and secondary packaging

Pharmaceutical companies that market medicines in several countries must reconcile differing national market requirements with coordinated production and packaging planning. Whilst manufacturing and primary packaging are often designed for larger volumes, the subsequent secondary packaging requires differentiation according to the destination country and product variant.

Different language versions, country-specific package leaflets, labelling requirements and security feature specifications all influence the design of the secondary packaging. The applicable serialisation requirements must also be taken into account during the planning stage. This increases the demands placed on format changes, the provision of materials and the coordination of packaging orders.

One possible approach to designing international supply chains is late-stage customisation. This involves tailoring the secondary packaging to specific countries as late as possible in the process. Whether and to what extent this approach is suitable depends, amongst other things, on the product requirements, the approval status and the regulatory requirements of the respective markets.

Early packaging and its impact on stock planning

If medicinal products are fully packaged for individual target markets at an early stage, this can complicate subsequent stock planning should demand trends change. Stock that has already been packaged specifically for a particular country cannot easily be used for other markets, as labelling, package leaflets and other packaging features are tied to the respective requirements.

This can have various operational implications:

Allocated stock: Ready-made goods are allocated to a specific market and the packaging requirements applicable to that market.
Additional adjustment requirements: Changes in demand, regulatory approval or labelling may necessitate further coordination or – where permitted – additional packaging steps.
Warehouse planning requirements: Separate stocks for different countries and product variants place greater demands on stock management and warehouse capacity.

The actual impact depends on the product structure, sales volumes and the specific supply chain organisation.

Late-stage customisation: country-specific differentiation at a later stage

In late-stage variant creation, suitable intermediate stock is initially made available in as standardised a form as possible. Country-specific secondary packaging is then carried out in accordance with specific requirements and the applicable product and market requirements.

Depending on the product and the authorised manufacturing process, suitable primary packaging or uniformly prepared intermediate stocks, for example, may be considered as a starting point. The specific arrangement must ensure that all necessary quality, regulatory and documentation requirements are met.

Late variant formation can provide additional flexibility. However, it is not equally suitable for every medicinal product or every marketing authorisation structure. In particular, the requirements regarding labelling, traceability, packaging materials and batch documentation must be taken into account.

Variant management and changeover times in secondary packaging

With every additional product variant, the demands placed on the technical and organisational preparation of the packaging line increase. Different package inserts, print designs, coding and packaging components may necessitate format changes and additional process checks.

Where changeovers are frequent and batch sizes are small, the time spent on set-up, adjustment and process approval can account for a significant proportion of the total production time. Cost-effectiveness therefore depends not only on the available line capacity, but also on the design of the changeover processes and the coordination of production orders.

Standardised set-up procedures, suitable format components and digitally supported control processes can help to prepare recurring set-ups in a structured manner. Camera systems and other in-process controls assist in verifying defined labelling and packaging characteristics. The specific functions and inspection procedures depend on the equipment used, the product and the applicable quality requirements.

The following aspects are particularly relevant when planning country-specific variants:

Format and material coordination: Package inserts, folding cartons, labels and other packaging materials must be assigned to the relevant national product variant.
Labelling and serialisation: Print data and the required security features must be integrated into the packaging process in accordance with the specifications of the target market.
Process control and documentation: The relevant tests and process data must be recorded in a way that ensures full traceability.
Set-up and capacity planning: The frequency and scope of format changes should be taken into account in production planning.

Impact on international supply chains

The late emergence of variants can help to keep the allocation of stock to individual markets open for longer. Under the right conditions, this makes it possible to tailor packaging orders more closely to actual demand and to reduce stock that has already been packaged for specific countries.

This requires coordinated planning of storage, material availability, packaging capacities and dispatch. The remaining shelf life, the permitted use of interim stock and regulatory requirements must also be taken into account in the decision-making process.

A subsequent market allocation therefore does not automatically mean that stocks can be moved between countries at short notice. Rather, it provides an additional planning approach, provided that the product and regulatory structure allow for such an approach.

For pharmaceutical companies, it may be advisable to consider the design of secondary packaging in conjunction with stock and supply chain planning. This allows potential requirements relating to variant management, storage capacity and production lead times to be taken into account at an early stage.

Conclusion: Aligning packaging planning with market demand

Late variant development is one possible approach to better coordinate country-specific packaging requirements with the planning of international supply chains. Its benefits depend on the specific product and regulatory structure, as well as on the coordination between storage, secondary packaging and dispatch.

In addition to inventory planning, format flexibility, set-up times and documented process workflows also play a role. Assessing these factors at an early stage can help to develop suitable packaging strategies for different markets and batch sizes.
