How to package products to reduce damage and shipping costs

Start with the product and its risks

Record weight, dimensions, sensitive surfaces, moving parts and leak risks. Also check whether the product can withstand pressure or contact with another item. A retail display carton is not automatically suitable shipping packaging.

For liquids, temperature-sensitive items and regulated products, have specific requirements checked before choosing a network. Good cushioning does not make prohibited or restricted goods eligible for unrestricted shipment.

Canada Post’s packaging guidelines by item type offer guidance based on contents. Supplement them with your manufacturer’s instructions and those of your chosen transport service.

Understand the role of cushioning

Cushioning keeps products from moving and can help absorb impacts. Paper, air pillows, dividers, moulded protection and foam do not all serve the same purpose. Choose the material according to weight, fragility and the space that must be maintained.

Adding lots of material to a large box does not always correct a poor design. A heavy object may compress cushioning that is too soft. Two bottles can strike each other if a divider moves. Check the arrangement after closing and handling the box.

Standardize the amount and position of protective materials. A photographed instruction is easier to reproduce than “add enough paper.” Also specify how to close the box and where to place the label so it remains readable.

Reduce volume and check billable weight

Shipping charges may be based on dimensional weight when a parcel takes up a lot of space. FedEx Canada explains that it compares actual weight with dimensional weight and uses the higher figure. Its published formula for dimensions in centimetres uses a divisor of 5,000. Check the rules for your service and agreement before calculating a price.

Dimension example for a parcel weighing 2 kg: a 40 × 30 × 25 cm box has a volume of 30,000 cm³, giving 6 kg with this divisor. A 30 × 25 × 15 cm box has a volume of 11,250 cm³, giving 2.25 kg. These results are before carrier rounding rules or other adjustments.

The second format reduces volume by 62.5%, but this does not mean the invoice will fall by 62.5%: rate bands, minimums and surcharges affect the price. It is only acceptable if protection remains adequate. Compare both the quoted rate and test results.

Measure the full cost of packaging

Add the box or mailer, cushioning, special protection, consumables and preparation time. Include the effect on shipping and the expected cost of damage. If customized presentation requires more handling, measure that time at the packing station.

Illustrative example: a box and protective materials cost $1.60, packing labour costs $0.90 and shipping costs $12, totalling $14.50 before incidents. Another format costs $2.10 in materials, $1 in labour and $10 in shipping, totalling $13.10. Despite more expensive materials, the second scenario saves $1.40 per order under these assumptions.

Do not count labour twice if your preparation rate already includes packing. Then compare observed damage: a theoretical saving of a few cents can disappear when a product needs to be replaced and shipped again.

Validate a format before rolling it out

1. Prepare several representative orders. Include the heaviest and most fragile combinations.
2. Measure the closed parcel. Record its external dimensions and weight, then check consistency at the workstation.
3. Check how securely the contents are held. Look for movement, contact and pressure points. Simple in-house handling is not a certification of package strength.
4. Plan tests appropriate to the risk. For fragile or valuable products, a packaging supplier or laboratory can define a suitable protocol.
5. Monitor the first shipments. Compare damage, customer feedback, preparation time and billing adjustments.

If damage occurs, keep the evidence needed for a possible shipping claim. A photo of the broken product helps, but the outer packaging and internal protection may be just as important.

Create a packing instruction sheet for your warehouse

For each order profile, specify the box reference, cushioning, sequence of steps, a photo of the finished package and exceptions. Keep a small set of formats that covers a large share of sales, with a process for orders that fall outside those formats.

When launching a new product or promotional bundle, communicate changes before the first orders arrive. Your order preparation and kitting service can then be organized with the right materials and time allowance. Also review free shipping thresholds when the format or number of parcels changes.
