Search custom packaging for a store that ships from China and you get packaging factories quoting their own boxes and dropshipping apps saying branding is possible. Each gives a minimum order or a unit price for one product. None works out what branding costs on every order, or what the box does to the shipping bill.

The cheapest way to brand a parcel is a printed insert card, at a few cents an order from a minimum of about 500. A printed poly mailer adds well under 50 cents and almost no weight. A mailer box costs about $1 to $2.55 an order at 1,000 units, and on a line that bills the greater of scale and volumetric weight, a box that is too big could double the weight you pay to ship.

This guide covers:

• The five ways to brand a parcel from China, from an insert card to a rigid box
• The minimum order and the cost per order for each, at about 1,000 units
• The cash a first run ties up at 50 orders a day
• How the lines out of China bill weight, and what a box does to it
• When a box could be worth it, and how to price it for your own product

The five ways to brand a parcel from China

A parcel shipped one order at a time from a warehouse in China can carry your brand in five places, roughly from cheapest to dearest:

• An insert card. A printed thank-you card, care guide or QR code to your reorder page, dropped in on top of the product.
• Printed tissue. A sheet wrapped around the product, the first thing the customer sees when the parcel opens.
• A printed poly mailer. The plastic shipping bag itself, printed with your logo. It replaces the plain grey mailer, so it adds almost nothing to the parcel.
• A mailer box. A printed corrugated box that folds shut, the usual unboxing box.
• A rigid box. A stiff two-piece or magnetic gift box, built for jewellery, cosmetics and gifts.

Stickers, branded tape and packing slips sit in between. A dropshipping app's glossary says they "often require low MOQs", while full custom boxes "typically demand higher volume".

What each costs per order, and the minimum to start

Published guides from packaging sourcing companies put the typical minimums and prices at:

• Insert cards: usually from 500 cards, about $0.05 to $0.13 a card at 1,000.
• Printed tissue: usually from 500 sheets, about $0.06 to $0.19 a sheet at 1,000.
• Printed poly mailers: from 100 at one US vendor, $0.38 for one colour to $0.48 for full colour at 1,000, and $0.69 to $0.85 at 100.
• Mailer boxes: typically from 500 to 1,000, about $1.00 to $2.55 a box.
• Rigid boxes: often from 100 to 500, about $1.90 to $5.10 a box at 500.

Three costs sit on top of the unit price. A sample run costs about $80 to $300, production takes about 20 to 35 days, and an independent inspection of the packaging factory costs about $200 to $350 a visit if you want one. Some factories print short digital runs of 50 to 100 at a higher unit price, which could suit a first test.

These are list prices and ranges, not quotes. The size, the paper, the number of colours and the finish move them a lot.

The cash a first run ties up

At 50 orders a day, 1,000 units of packaging covers 20 days of orders. Paid up front, that first run is:

• Insert cards: about $50 to $130
• Printed poly mailers: about $380 to $480
• Mailer boxes: about $1,000 to $2,550
• Rigid boxes: about $1,900 to $5,100

Two things follow. A box design is hard to change once 1,000 are printed, so test the product before the box. And a box run is sized to one product: if the product changes size, the boxes may not fit the next one. The guide to testing a product from China without an MOQ covers how to test before you commit.

The cost nobody adds up: the weight it ships at

The lines that carry parcels out of China price by weight. Which weight depends on the line. YunExpress, as published on its product pages on 20 October 2026:

• Standard Express bills "the greater of the package's actual weight and volumetric weight". Volumetric weight is length x width x height in centimetres, divided by 8,000 (6,000 for Canada).
• Economy Express to Canada and New Zealand bills the volumetric weight only if it is at least twice the scale weight.
• Some countries, Vietnam and the Philippines among them, are billed on scale weight only.

So the same product in different packaging can ship at a very different weight. Take an example product weighing 300 g:

• In a printed poly mailer (about 20 g): 0.32 kg on the scale, and flat, so it is billed at 0.32 kg.
• In a small mailer box, 20 x 15 x 5 cm (about 120 g): 0.42 kg on the scale. Its volumetric weight is 0.19 kg, so it is billed at the scale weight, 0.42 kg.
• In a larger mailer box, 25 x 20 x 10 cm (about 150 g): 0.45 kg on the scale, but its volumetric weight is 0.625 kg, so on a "greater of" line it is billed at 0.625 kg. That is about double the poly mailer.

On a line with the "twice" rule, the same larger box would be billed at its 0.45 kg scale weight, because 0.83 kg of volumetric weight (on the 6,000 divisor) is less than twice 0.45.

Packaging weights are from one packaging company's comparison: 0.5 to 1 oz (about 14 to 28 g) for a custom poly mailer and 4 to 16 oz (about 113 to 454 g) for a custom box. Measured per store on small parcels shipped from China, the typical parcel weighs about 200 to 500 g, so a 150 g box can add 30% or more to the weight before its size is counted at all.

What a tight pack is billed on

Parcels packed close to the product's size rarely reach the volumetric limit. On YunExpress parcels from stores shipping from a China warehouse, where the line reported both weights (late May to October 2026), the weight charged matched the scale weight on 999 in 1,000.

That cuts both ways. Packed tight, a parcel is billed on what it weighs, so every gram of packaging is paid for on every order. The box only changes the bill a second time when it is bigger than the product needs.

When a box could be worth it

• Fragile or rigid products need a box whatever it costs. A poly mailer protects against water and dirt, not crushing.
• Gifts, jewellery and cosmetics sold at a price where the unboxing is part of the product could carry a mailer or rigid box, if the margin covers a few dollars an order.
• Clothing and soft goods could get most of the brand for cents with a printed poly mailer, tissue and a card.
• A product still being tested might be better with an insert card only, until it sells every day.

A box size chosen for the product, not the brand's whole range, keeps the volumetric weight under the scale weight.

How to check it for your own product

1. Weigh the product packed, without branding, and note the size of the smallest box or mailer it fits.
2. Ask for a quote at your real quantity, with the size, paper, colours and finish written down, plus the sample fee and the production time.
3. Work out the volumetric weight of the box: length x width x height in centimetres, divided by the divisor your line uses (often 8,000 or 6,000). Compare it with the scale weight.
4. Price both weights on your line's rate card, then add the packaging cost per unit.
5. Divide the run by your daily orders to see how many days the first order covers, and how much cash it holds.

What to do

• Start with an insert card, the cheapest brand touch per order
• Print the poly mailer before you print a box, for soft products
• Size the box to the product, not the range, so it ships on its scale weight
• Ask your line how it bills weight to each country you sell in
• Order the first run for about three to four weeks of orders, not three months
• Test the product first, then the box

How we handle this at Commercive

Commercive is your all in one sourcing and fulfilment partner. We source from a product link or a photo across more than 1,845 vetted factories, or work with the supplier you already use, and we default to the no-minimum or lowest-minimum option so you can test a product from its first order.

Your stock is received on our floor in China, held with no storage fees, and each order is packed and shipped one by one. If you send or source your own packaging, there is no handling fee for using it: you pay for the packaging only. Our measured delivery times by line and country are on our shipping status page, and the guide to verifying a Chinese supplier before you pay applies to a packaging factory as much as a product one.

If you're currently running a brand, just give us the product and your daily order volume. We'll get you a quote within the next 24 hours to hold up against what you're paying today.

Where these facts come from. Billing rules are from YunExpress's Standard Express and Economy Express product pages, read 20 October 2026; other lines and accounts can bill differently. Packaging minimums and prices are from two packaging sourcing guides (updated 25 April and 20 August 2026, approximate prices from China, pounds converted at about $1.27), one US poly mailer vendor's price list (1 April 2026) and a dropshipping app's glossary; they are ranges, not quotes. The 300 g product and the box sizes are an example. Our own figures are YunExpress parcels from stores we fulfil: the billed weight check covers parcels where the line reported both weights, created late May to 20 October 2026; typical parcel weight is the median per store, June to September 2026.

What is the cheapest way to brand a parcel shipped from China?

A printed insert card. Published guides put them at about $0.05 to $0.13 a card at 1,000, usually from a minimum of about 500. A printed poly mailer is next, at about $0.38 to $0.48 at 1,000 from one vendor, and it replaces the plain mailer instead of adding to it.

What is the minimum order for custom mailer boxes from China?

Typically 500 to 1,000 boxes, at about $1.00 to $2.55 a box in one 2026 sourcing guide. Some paper and cardboard factories go as low as 100 to 200, and some print short digital runs of 50 to 100 at a higher unit price.

Does a box cost more to ship than a poly mailer?

Usually, in two ways. The box adds weight, about 113 to 454 g in one packaging company's comparison against 14 to 28 g for a poly mailer. And on lines that bill the greater of scale and volumetric weight, a box bigger than the product needs is billed on its size: in the example above, about double the poly mailer.

How do I work out volumetric weight for a parcel from China?

Multiply length, width and height in centimetres and divide by your line's divisor. YunExpress Standard Express uses 8,000 for most countries and 6,000 for Canada, as published on 20 October 2026. If the result is above the scale weight, a "greater of" line bills that instead.

Can a dropshipping agent use my custom packaging?

Most fulfilment partners in China can pack orders in packaging you supply or have made, with your insert or mailer added at packing. Ask whether there is a handling fee for it, where the packaging is stored, and how many days of stock they want on hand.
