Start with a single file that will be the working record for packaging decisions. That file should answer five questions: what goes in the pack, how it is protected, how it is presented to retail, how it is boxed and shipped, and who signs off. This article breaks each topic into the explicit asks to send to a supplier, what to compare across quotes, and how to record the decision for your sourcing file.

Define the scope and deliverables for each SKU

Begin by naming the responsible parties and the document version. For each SKU, list the product name, SKU code, net weight, gross weight target, and any variants that change packaging such as color, size, or accessory kits. State whether this is for sample, pre-production, or mass production so the supplier knows the expected tolerance on dimensions and materials.

Second, state the deliverables you expect from the supplier. That includes printable dielines or CAD files for all packaging tiers, a photo set of packed product, an initial sample type to be produced, and a simple acceptance checklist. If you need art proofs or certificate copies from a third party, name them. A short bullet list can make deliverables clear:

bullets:[

• Product list with SKU codes and variants
• Requested deliverables: dieline, sample type, photos, checklist
• Who approves and the target approval timeline

Specify dimensions, materials, and allowable tolerances

Give exact measurements in clear units. For every primary and secondary package, provide finished external dimensions, internal cavity dimensions, wall thickness, and required clearance around the product. Note the unit of measure, decimal precision, and the acceptable tolerance band for each critical dimension so there is no ambiguity on what passes QA.

Describe materials by function, not vague names. For example, say inner tray material and minimum caliper, foam density and cell type, or corrugated flute and board weight if you care about crush resistance. If color matters, reference a specific color code and show a sample image. State adhesive type, closure method, and any special surface finish requirements such as matte film lamination or varnish.

• List dimensions with units and tolerances for external box and internal cavity
• Specify material by functional property such as caliper, density, or surface finish

Write protective packaging requirements the supplier can perform

Define the protective goal and the test or field condition that proves it. Instead of saying protect for shipping, state the expected shipping scenario: number of unit shifts during handling, whether items are palletized, expected drop height for cartons, or if exposure to humidity is likely. Then ask the supplier to propose protective materials and show calculations or past sample photos that demonstrate the chosen solution.

Be explicit about how you will judge protection on the first production run. Ask for a photographed pre-shipment sample with the product removed to show cushion placement and clearance. If you want compression or drop testing, name the test method you intend to use and the pass-fail criteria. If you are unsure which test applies, ask the supplier to recommend commonly used tests and provide a quote to run them, then decide with that data.

• State the shipping and handling conditions you need protection for
• Request photographed samples and a named test method with pass-fail criteria

Specify labeling, artwork placements, and retail readiness

Provide exact label artwork files and call out placement coordinates on dielines. Specify orientation relative to the product and to the carton top. If labels must resist abrasion or moisture, state adhesive type and expected surface conditions. For barcodes and scannable labels, define size, quiet zone, and minimum print quality rather than saying meet retail standards without detail.

Clarify any retail-ready presentation you require: hanging tab locations, window cutouts, or shelf-facing face. Ask the supplier to produce a packaging mockup photograph with a ruler or scale bar visible so you can confirm alignment and legibility. If multiple languages or warning marks must appear, attach final text and indicate preferred font sizes and contrast levels to avoid back-and-forth.

• Attach final artwork and indicate exact placement coordinates on dielines
• Request mockup photos with scale for approval

Set carton, palletization, and outbound handling rules

List carton quantities, orientation, and how mixed SKUs are arranged if applicable. State target carton dimensions, maximum weight per carton, and a maximum stack height for pallet builds. If cartons ship as full pallets, specify pallet pattern, allowable overhang, and whether plastic or wood pallets are required. Ask for the planned pack layout diagram and a photo of a trial pallet.

Make logistics constraints explicit so packing decisions are executable. Note any cube limitations for air freight, preferred carton marking content and location, and whether outer cartons must be banded or stretch-wrapped. Request a shipping-mark template that the supplier will print and confirm who will apply export labels or cords at origin.

• Provide carton quantity per inner unit and max weight per carton
• Request pallet pattern diagram and trial pallet photos

Define approval samples, change control, and the decision record

Specify which sample types require approval before mass production: prototype, pre-production, and first-article. For each, list the acceptance criteria that must be checked and the data the supplier must return with the sample, for example measured dimensions, material batch, and photos of protective inserts. Say whether you accept electronic approvals or require physical sign-off, and set a deadline for supplier response after sample delivery.

Outline a simple change-control process. Require the supplier to submit a change notice with comparison photos and a rationale before modifying material, carton size, or label art. Record each approval in the working file with version numbers and dates so the next sourcing decision can reference the approved configuration. A short sample checklist helps make approvals repeatable:

bullets:[

• Sample type required
• Measured dimensions vs tolerance
• Photos of internal packing and carton markings
• Date, approver name, and version number

Create one packaging working file per SKU and send it to the supplier for a first-sample quote.
