How to Switch Packaging Suppliers Without Disrupting Shipping

Most businesses stay with a packaging supplier long past the point it makes sense, because switching feels risky and the current arrangement is at least predictable. The risk is real but it is narrow, and it is entirely manageable once you know where it sits.

The one thing that goes wrong

You run out of the old packaging before the new packaging arrives, and you spend a fortnight buying boxes at retail prices to keep shipping.

That is the whole risk. Everything else is comparison shopping. The defence is an overlap: place the first order with the new supplier while you still have six to eight weeks of the old stock left. If the new supplier is slower than promised, you absorb it without noticing. If they are on time, you have a short period holding both, which costs a little space and nothing else.

Compare specifications, not prices

A quote that looks cheaper is often a lighter product, and comparing headline prices without checking what is behind them is how businesses end up with packaging that fails.

• Board grade and wall — single or double wall, and which flute. A single-wall box priced against your double-wall one is not a saving.
• Film thickness — poly mailers are sold in mil or micron. A thinner bag is cheaper and splits more.
• Internal versus external dimensions — boxes are normally quoted internally. Confirm which you are being given, because the difference decides whether your product fits.
• Units per carton — affects handling and storage more than people expect.
• Whether freight is included — the most common hidden difference between two quotes.

Get the freight number before you decide

Packaging is light and bulky, which is the worst combination for shipping cost. A supplier who is a few pence cheaper per unit and further away can easily be more expensive delivered.

Ask for the landed cost to your actual address, for the actual quantity. Any supplier who will not quote freight until after you commit is telling you something.

Check the thing that is not on the quote

Price is easy to compare and rarely the reason a supplier relationship fails. These are:

• Do they answer? Send a question before you order and see how long the reply takes. That is your future experience when something goes wrong.
• Is the price ladder published? A supplier who quotes case by case is a supplier you renegotiate with every time.
• What is the real lead time in your peak season, not in February?
• What happens if a delivery is short or damaged? Ask before it matters.

Run one product first

Do not move your whole range in one go. Take a single high-volume line, order it at the minimum, and use it properly for a few weeks.

You are checking things a specification sheet cannot tell you: whether the seal holds, whether packers find it quicker or slower, whether the print quality is what you expected, whether damage rates change. Those show up in use, not on paper.

A sensible sequence

• Week 0 — specifications and landed cost from the new supplier, checked against what you currently use.
• Week 1 — order one line, while six to eight weeks of old stock remains.
• Weeks 2–5 — use it. Watch seal failures, damage claims and packer feedback.
• Week 6 — if it holds up, move a second line. If not, you have lost one order and learned something cheaply.
• Month 3 — move the rest, with a forecast based on real usage.

Handled that way, changing supplier is an admin task rather than a risk. If you want to compare against what you currently buy, send us the specification and the quantity and we will price it properly — including freight to your address.
