A Clearer Brief Helps Us Review the Job
What to Include in a Custom Packaging Quote Request
You do not need to know every packaging term. These four details usually provide a much better starting point than choosing a box solely by appearance.
Product dimensions and weight
Measure the product as it will actually sit inside the pack. Include accessories, inserts or wrapping, and add the approximate packed weight when it matters to the structure.
Quantity you expect to order
Tell us the quantity that suits the project rather than choosing an arbitrary figure. Low MOQ options can support launches, smaller runs and growing ranges where applicable.
How the box will be used
Explain whether the pack is for ecommerce, postal delivery, shipping, subscription orders, gifting or another use. The delivery route can affect the structure you choose.
Artwork, printing and features
Share your logo or artwork if it is ready. Otherwise, describe the print, colours, insert, tear-strip, self-seal or presentation requirements you already know.
Not Sure Which Postal Box to Request?
Start with the product rather than forcing a box style too early. You can compare Custom Mailer Boxes, Custom Shipping Boxes, Postal Boxes by Size and Packaging Materials before submitting the form.
If you would rather explain the project first, contact Custom Postal Boxes and share the product dimensions, quantity and intended use.
UK businesses that supply or import packaging or packaged goods may also have responsibilities under the official GOV.UK Extended Producer Responsibility for packaging guidance.
What Happens Next
From Packaging Enquiry to Quotation
The purpose of the quote form is to establish a usable brief. Once the important details are clear, the packaging specification and quotation can be considered around the same information.
We review the brief
We look at the product, dimensions, quantity, intended use, box direction and any artwork or reference material you have supplied.
We clarify the specification
If an important detail needs confirming, the discussion can focus on that point rather than making assumptions about the finished packaging.
Your quotation is prepared
Once the brief is clear, the quotation can reflect the agreed size, quantity, structure, printing and other relevant requirements.
Custom Postal Boxes is a project of Vertex Packaging. The site focuses on postal, mailer, shipping and related ecommerce packaging while keeping that wider business relationship clear.
Practical Answers
Custom Packaging Quote FAQs
These answers cover common questions that come up before a UK business sends a postal packaging enquiry.
What information do I need for a custom packaging quote?
Start with your product dimensions, approximate packed weight where relevant, required quantity and intended use. Add your preferred box style, artwork, printing or special features if you already know them. You can still submit an enquiry when some of those details are undecided.
Can I request a quote if my artwork is not ready?
Yes. Custom Postal Boxes provides free design support, so you can begin with your logo, colours, product information or a reference direction. It is usually more useful to settle the box structure before final artwork placement.
Can I request custom postal boxes in my own size?
Custom dimensions can form part of the brief. Measure the product in its packed state, including any insert, wrapping or accessories. Those dimensions provide a more reliable basis for discussing internal clearance and the finished box size.
Can you help me choose between a mailer and shipping box?
Yes. Explain the product dimensions, packed weight, delivery route and how you want the customer to open the package. A mailer may suit many customer-facing ecommerce orders, while shipping formats can be more appropriate for other transit requirements.
Do you offer low minimum quantities?
Low MOQ options are available. The suitable quantity can depend on the structure and specification, so include the quantity your project genuinely needs instead of assuming one minimum applies to every box.
Is UK delivery available?
Yes. Custom Postal Boxes provides fast and free UK delivery. If your packaging is linked to a launch, stock intake or other fixed date, include the required timing in the enquiry so it can form part of the project discussion.
