Are My Current Packaging Suppliers Still the Best Option as My Needs Evolve?

Most companies do not question their packaging supply chain until something goes wrong. A missed shipment. An inconsistent print run. A supplier who cannot accommodate a new pack format. By the time these problems surface, they have already cost time, money, and in some cases, a product launch.

The reality is that your business is not static, and your packaging supply chain should not be either. As you scale, enter new markets, introduce new SKUs, or update your sustainability commitments, the packaging suppliers that served you well at one stage of growth may not be the right fit for the next. This does not mean you need to replace them. It does mean you need to regularly assess whether the relationship is still working and whether the capabilities on both sides are still aligned.

This guide covers the practical steps involved in doing exactly that.

The Foundation: Clarity on Both Sides

Before any formal vendor review, it helps to be honest about how most supplier relationships actually work. Packaging buyers often have a general sense of what they need but have never formally documented it. Suppliers, in turn, develop assumptions about a client's requirements based on past orders, without ever being told explicitly what good looks like.

The result is a relationship that functions adequately in normal conditions but becomes fragile the moment requirements change or volumes grow.

The most effective way to prevent this is straightforward: be explicit about your requirements and measure your suppliers against them on a consistent basis. Suppliers who receive clear, regular feedback know exactly where they need to improve. Buyers who understand their suppliers' actual capabilities, lead times, and process constraints are far less likely to be caught off guard.

A mismatch between what a buyer expects and what a packaging supplier can actually deliver is the root cause of the vast majority of packaging supply chain problems. In most cases, it is not a failure of intent on either side. It is simply a failure of communication.

Step 1: Conduct a Structured Vendor Performance Review

A semi-annual or annual vendor performance review is one of the most useful and underutilised tools in packaging procurement. It does not need to be complicated, but it does need to be consistent.

When evaluating your current suppliers, consider the following across each major area:

Quality — What is the defect rate on incoming packaging? Are quality issues recurring or isolated? Are root causes being identified and addressed, or are the same problems appearing across multiple deliveries?

Delivery — What is the on-time delivery rate? When delays occur, how much advance notice is given and how effectively are they managed?

Communication — How responsive is the supplier to queries, specification changes, and escalations? Is there a designated point of contact who understands your account?

Capability — Can the supplier handle your current requirements without outsourcing any part of the process? Do they have the capacity and technology to support your anticipated growth over the next 12 to 24 months?

Compliance — Are all relevant certifications current? If your procurement requirements include FSC, BRC, Sedex, or GMI, is the supplier maintaining those standards consistently?

The output of this review should be shared directly with your packaging suppliers. The goal is not to create a performance report for internal use; it is to give your suppliers the information they need to improve. The most effective packaging relationships are ones where both sides are working toward the same targets.

Step 2: Define Clear Criteria Before Adding New Suppliers

If your review identifies capability gaps that your current suppliers cannot address, adding new suppliers to your network is a reasonable response. But the qualification process matters. A new supplier who cannot consistently deliver to your standards creates more problems than it solves.

A structured supplier qualification should cover the following areas:

Certifications — Quality and ethical production standards are most reliably demonstrated through independent certification. Depending on your industry and geography, look for ISO 9001 for quality management, ISO 14001 for environmental management, BRC IOP for food-adjacent and consumer goods packaging, FSC Chain of Custody for responsibly sourced paperboard, GMI or G7 certification for colour consistency, and Sedex audit status for ethical supply chain compliance. Most certification bodies maintain searchable directories that allow you to verify a supplier's status directly, including the FSC, BRCGS, and G7 directories.

Client Profile — A supplier's track record with clients in your industry is one of the most reliable indicators of their ability to handle your requirements. Look for evidence of experience with brands at a comparable scale and complexity to your own. Generic claims of capability are less useful than specific examples of similar work.

Site Audit — Wherever possible, conduct a physical visit or supplier audit before formalising a new relationship. A site visit reveals things that a capability questionnaire cannot: the condition and maintenance of machinery, the training level of the production team, how quality checks are carried out on the floor, and how the facility is generally managed. If a physical visit is not practical, request a virtual audit or ask for references from existing clients in your sector.

Step 3: Align Requirements and Capabilities Systematically

Once you have identified a supplier worth evaluating seriously, the next step is a detailed capability assessment. The goal is to establish, with precision, where your requirements and the supplier's capabilities overlap, and where they do not.

We recommend developing a standardised questionnaire for this purpose. The following questions form a practical starting point, which you should adapt based on your specific packaging formats and industry requirements:

Question

• Which packaging formats do you produce in-house — folding cartons, rigid boxes, blister cards, corrugated boxes, pouches, tubes?

• Which post-press finishing processes are done in-house — foiling, embossing, lamination, window pasting, UV coating?

• What quality control processes are in place during and after production?

• What printing technology do you use, and at what press speeds?

• What is the minimum order quantity for each product line?

• What are standard production lead times for each packaging category?

• Are there any raw materials or processes with long procurement timelines that we should plan around?

• What paperboard grades, recycled materials, and speciality substrates can you source and convert?

• Are all processes handled in-house, or are any steps outsourced?

• What is your daily production capacity by product line?

• What are typical raw material procurement lead times?

  
  

The answers to these questions will quickly reveal whether a supplier is genuinely set up to handle your requirements or whether there are structural limitations that will create friction over time. Pay particular attention to questions around outsourced processes, since any step that leaves the supplier's own facility introduces an additional point of risk in your supply chain.

How Kumar Printers Can Help?

Over the past 60+ years, we have worked with packaging buyers at every stage of business growth, from early-stage brands placing their first structured packaging orders to multinational procurement teams managing complex, multi-SKU programmes across multiple markets. We have worked with global companies including Venus, Gillette, Nestle, and Gurkha and Guns to develop and launch new packaging in the Indian market.

Whatever the specific challenge, our team approaches every client engagement the same way: by understanding your requirements in detail before recommending anything.

If your priority is cost reduction, our sales team can work through your current specifications and identify where savings are available. Where it makes sense, our product development team can suggest material alternatives or process adjustments that reduce cost without affecting pack performance or brand presentation.

If you are looking to strengthen your sustainability credentials, we can advise on FSC-certified board options, plastic elimination strategies, and process changes that improve recyclability, all backed by our own certified supply chain.

If you are dealing with quality problems, whether persistent defects, colour inconsistency, or structural failures, our team can help identify the root cause and implement a lasting fix rather than a workaround.

All packaging development work, including structural design, sampling, and costing, is offered at zero or nominal cost to our clients.
