Alternate Packaging Supplier Qualification Checklist

Qualifying an alternate packaging supplier requires a defined equivalence review, not just a matching catalogue description. Identify the current approved pack and the alternative proposal, then ask the responsible teams which evidence and trials are needed. A similar-looking pouch or a quoted matching thickness does not establish interchangeability for the actual product and filling line.

Describe the approved baseline

Collect the active specification, drawing, artwork, closure references and accepted sample identity. Record the product, filling operation, storage and use conditions that the current approval covers. Where the existing requirement is incomplete, identify the gap instead of asking the alternate supplier to guess it from a photograph.

Separate requirements that must remain the same from preferences the buyer is willing to reconsider. A supplier may offer a different construction or format, but it should be identified as a proposal requiring review rather than described automatically as the same packaging.

Ask for an explicit alternative proposal

The alternate supplier should identify the proposed pack, relevant manufacturing route and the evidence available for the application. Keep its specification reference distinct from the incumbent reference. Procurement can create a cross-reference between the proposals without erasing their technical identities.

General process context is available from BOBST. Printing and converting descriptions help frame questions, but they do not establish that two suppliers produce the same complete pack.

Define the trial before the sample arrives

Ask the technical owner and filling team to identify the required observations and acceptance criteria. Record the proposed sample identity and how it relates to the alternative specification. Keep any restrictions on the scope of acceptance explicit.

An alternate supplier review should not use the incumbent's evidence as though it were a test of the new proposal. Relevant historical information can inform the review, while the responsible team decides what additional evidence is required for the actual alternative.

An illustrative equivalence gap

Suppose an alternate supplier offers a pouch with the same nominal width, height and printed front panel as the current pack. The closure arrangement and proposed construction have not been compared. The offer is a candidate for review, not an approved interchangeable substitute.

Create a difference register, identify the revised sample and ask the technical team to close the application and filling questions. Review the commercial and shipment terms on a separate basis. This example illustrates the decision process and does not claim that either construction is suitable or that a specific test result can be transferred.

Define what must remain equivalent

Start with the buyer's actual requirements and the current accepted scope. Separate mandatory application and line requirements from preferences open to change. An alternate supplier can propose a useful different solution, but it should remain an identified alternative until reviewed. Do not ask for same as existing without supplying the relevant controlled references and explaining which characteristics matter to the task.

Where the baseline is incomplete, assign the missing requirement to the appropriate buyer owner. A photograph or nominal thickness cannot reconstruct every property of the accepted pack. The incumbent's specification can inform the review subject to the buyer's rights and authorised information-sharing process. Keep confidential or restricted content within the agreed exchange rather than circulate it broadly as a generic matching brief.

Preserve separate supplier identities

Give the alternate proposal its own specification, drawing and component references. Build a buyer cross-reference without renaming it as the incumbent pack. Ask the supplier to identify relevant production and supply responsibilities for its actual offer. Similar process terminology does not establish identical output. The evidence and accepted scope must refer to the candidate actually proposed.

Record documented similarities, differences and missing information against the baseline. Give each entry a source. Do not mark a field same because neither proposal describes it. A supplier's equivalence statement is a claim to assess with its supporting information. The competent owners decide whether the alternative meets the required task, not an overall similarity percentage generated from a list of convenient fields.

Map differences to application questions

Identify which functions or interfaces a difference may affect. These may include geometry, opening, closure, printing orientation, product interaction or the filling route. Ask the relevant owners what evidence is needed and why. Keep questions separate until their relationship is understood. A dimensional match cannot cancel an unresolved material or closure question, and a familiar artwork family does not establish line interchangeability.

Assess what historical evidence can legitimately inform the review. The incumbent's result is not a test of the alternate's specimen. A competent reviewer may use it as context while requiring different evidence for the new proposal. Record that rationale. Avoid both automatic full repetition and automatic transfer of approval. The decision should focus on the actual differences and intended use.

Define the sample and trial stages

Request an identified candidate and a differences table before it arrives. State which questions the submission is intended to address. A visual model, construction sample and production-representative submission can have different purposes. Record limitations rather than force one sample to support every decision. The relevant technical owners determine the protocol and acceptance for the actual application.

Connect dispatch and receipt identities to the trial record, but keep their decisions distinct. A complete delivery establishes the handover, not technical acceptance. For several lines, preserve local references and decision states. One completed review may support a scoped next step while another remains open. The alternate-supplier conclusion should describe that actual position instead of declaring universal interchangeability.

Review the illustrative nominal-size match

In the existing example, the alternate has the same nominal width, height and front artwork while closure and construction remain unresolved. Record those two questions specifically. Ask for controlled references and let the relevant owners identify evidence needs. The offer can remain commercially interesting while the technical status is pending. Do not call the pack equivalent simply because the familiar dimensions are the easiest fields to compare.

If the alternate proposes another closure to meet the use task, assign a revised candidate. Ask which earlier observations remain applicable and why. Keep the old and new references in the development history. The comparison then documents a deliberate alternative solution, rather than an unexplained change concealed under the original matching-pack request.

Plan dual-source orders after acceptance

Maintain supplier-specific item and artwork references in the buyer master. Identify accepted plants, applications and conditions for each source. Give receiving and quality the information needed to distinguish them. A common internal family code can support commercial planning while still linking to the exact accepted supply. It should not erase meaningful differences required for inspection or investigation.

When the buyer changes product, artwork, construction or line scope, review both sources through their actual affected records. A change accepted at one supplier does not automatically cover the other. Keep notification, evidence and introduction decisions linked to each candidate. Ask whether existing stock and open orders need a transition decision under the buyer's process.

Keep the alternate's business role explicit

State whether the accepted source is intended for routine shared demand, a defined contingency or another agreed role. Obtain actual commercial quantity, schedule and delivery conditions. Technical acceptance does not establish available capacity or a guaranteed emergency response. Record the supplier's current offer and the buyer's decision without assuming reserve stock or production availability. The useful result is an alternate that can be ordered correctly within a defined scope, with its evidence and responsibilities retrievable.

Control dual-source ordering

If the alternate is accepted, record exactly which specification, artwork, plants and applications it can support. Keep supplier-specific references in the order master. Tell receiving and quality teams how to identify the supplied version and where its evidence is held.

When the buyer changes a product or pack requirement, review both sources rather than assuming the accepted change at one supplier automatically covers the other. Nestle's vendor quality document is one example of buyer-specific controls; follow the actual customer's requirements for a second source.

Alternate supplier: a practical specification example

A procurement team is moving from a trial order to a repeat programme. Give the packaging a stable item identity that links drawing, material, artwork, closure and quantity unit. Keep plant-specific handling or delivery needs beside that shared item definition. The same product name can otherwise conceal different dimensions or artwork revisions when several people place orders.

For this decision, start with the common specification and any proposed differences. The useful output is a comparison that makes substitutions visible. Put that output beside the relevant quotation, drawing or sample rather than leaving it in a separate email. This is an illustrative decision exercise, not a report of a completed customer trial.

Product references to make the discussion concrete

The catalogue includes flat-bottom pouches and courier bags. These examples show different physical constructions; they are not interchangeable specifications. A box-style base gives the filled pack a distinct footprint, with separate front, back and side panels. Compare a plain top opening with a regular zipper, and use filled samples to decide the shelf depth and panel proportions.

Use the reference pictures to identify the base, side panels, window or opening that you mean. A picture cannot supply the missing dimensions or material layers. If a photograph shows a finish or closure you do not want, state that difference explicitly; otherwise a visual reference can introduce an unintended requirement.

Complete the record before requesting the next sample

1. Attach a comparison that makes substitutions visible. Identify the product or SKU and the date of the observation.
2. Record the common specification and any proposed differences. Keep confirmed information separate from proposed values and questions for the supplier.
3. Add the actual fill weight or volume, the dimension convention, material proposal and intended closure. Include the number of designs and quantity per design when requesting a quotation.
4. State which question the next drawing, sample or quotation must resolve. A change of size, closure or material should remain visible alongside the earlier reference.

This record makes the next conversation specific. It lets the design, purchasing and packing teams work from the same proposed item and shows which decision still needs evidence. Review the related product pages for format details, or prepare a custom packaging brief with the unresolved requirements.

Close with a defined approval scope

Use a final decision such as accepted for the identified requirement, accepted with listed limits, further evidence required or not suitable for the current application. Retain the comparison, samples and decision records. The value of a second source is stronger when the buyer can order the correct version without assuming technical equivalence.

Send the current approved baseline, permitted differences, product and filling requirements, proposed quantities and decision owners with an alternate-source enquiry. Ask the supplier to identify differences and open evidence questions before commercial preference becomes a substitution decision.
