Domestic China shipping is the cost most 1688 importers leave out of their landed cost calculation. It is not the largest line item, but it is consistently missing, and over time that gap quietly erodes the margins you thought you had.
What domestic China shipping actually is
When you place an order on 1688, the supplier does not ship directly to your international freight carrier. They ship to a consolidation warehouse in China, typically in Guangzhou, Yiwu, or Shenzhen. The leg from the factory to that warehouse is domestic China shipping, and it carries a fee.
A typical 1688 order travels at least two legs before it leaves China. Leg one: the factory sends the goods to the consolidation warehouse through one of China's domestic express networks, most commonly Zhongtong, Yuantong, Yunda, SF Express, or a similar carrier. Leg two: the warehouse receives, inspects, and consolidates your parcels before dispatching them on the international route you selected. The fee on leg one is what this is about.
This is not a hidden fee in the sense of being deliberately buried. The "yun fei" (freight fee) field on a 1688 product page usually shows the domestic shipping rate the supplier charges. The issue is that buyers skim past it while comparing product prices, or assume it is already built into the listed price. It is usually not.
How the fee is calculated
Domestic China shipping does not follow a single standard. Each supplier sets their own rate or has a contract with their preferred domestic carrier. But a few pricing models come up repeatedly.
By actual weight. Some factories charge a flat rate per kilogram of actual parcel weight. Typical ranges fall around 2 to 8 yuan per kg for light to medium goods, varying by domestic route and carrier. Heavier freight, or goods traveling longer internal distances (say, from Sichuan to Guangdong), can run noticeably higher.
Per parcel, fixed fee. For small, light goods, many suppliers charge per box regardless of weight, something like 4 to 10 yuan per parcel. If you order 50 items but the factory packs them into 3 boxes, you pay three times that rate.
Free domestic shipping above a threshold. Some direct factories offer free domestic shipping once an order crosses a minimum value, often around 500 or 1,000 yuan. This is worth asking about directly, because it is not always stated up front.
Absorbed into the unit price. Some suppliers roll the domestic shipping cost into their listed price without separating it. In that case, you will not see a line item for it, but you are paying it. If you negotiate the unit price down and they suddenly add a separate freight charge, the previous price had it built in.
Why it is routinely missed
A few patterns show up consistently.
Attention goes to the product price. When comparing suppliers, buyers focus on unit cost and gloss over the smaller number below it. A supplier with a unit price 3 yuan lower but a domestic shipping charge of 6 yuan per parcel is actually more expensive in total.
Confusion with consolidation warehouse fees. Your consolidation warehouse or order agent charges their own service fees: weighing, repacking, storage. New importers sometimes assume that covers the domestic freight from the factory too. It does not. The warehouse fee covers what the warehouse does; the factory-to-warehouse leg is a separate charge that either the supplier or the domestic carrier bills.
Small amounts on small orders. On a test order worth 200 to 300 yuan, a domestic shipping fee of a few tens of yuan feels negligible. Multiplied across every order in a month, across several SKUs, it becomes a real number that was never in the spreadsheet.
Using an order agent without reading the invoice. When you rely on an agent to handle the 1688 purchase, it is easy to treat their summary invoice as final without checking every line. The agent pays the domestic freight on your behalf and rolls it into their invoice. If you are not reading each line, it disappears into "total agent fees" and never shows up in your per-unit cost calculation.
The real impact on landed cost
A concrete example makes this clearer.
You order 100 door hooks at 6 yuan each: 600 yuan in product cost. The factory packs them into 4 small parcels, each about 2 kg. Domestic shipping at 3 yuan per kg comes to 24 yuan total. That is the number that gets dropped.
Converting to dong at around VND 3,600 per yuan (the actual rate shifts, so check it when you calculate): 24 yuan is roughly 86,000 VND across the order, or about 860 VND per unit. If your target selling price is 45,000 VND and you estimated a 6,000 VND margin per unit, this missing 860 VND consumes roughly 14 percent of the margin you thought you had. On heavier goods or larger orders, that proportion grows.
In absolute terms the number is small. As a share of a thin margin, it is not.
How to include it correctly
The simplest step is to ask the supplier directly before you place the order: what is the domestic shipping charge, is it by weight or per parcel, and at what order size does it become free?
Once you have the number, the correct approach is to add the domestic shipping fee to the product cost in yuan before converting to dong, not to calculate it separately and add it later. The reason is straightforward: you are converting yuan-denominated spending to dong, and domestic shipping is yuan-denominated spending just like the product price is.
The right formula per unit is:
Unit cost in yuan = (product cost + domestic shipping fee) / quantity
Then multiply by the exchange rate to get your base cost in dong, before adding international freight, import duties, and any other fees downstream.
For the example above: (600 yuan + 24 yuan) / 100 units = 6.24 yuan per unit, then convert and continue building up landed cost from there.
If you use an order agent, ask for an itemized invoice. A well-structured agent invoice shows product cost, domestic freight, agent service fee, international freight, and customs handling as separate lines. If yours shows only a single "total" figure, ask for the breakdown. You need each line to calculate margin accurately and to know where to negotiate.
When this fee is worth negotiating
Most small buyers have limited leverage on domestic shipping fees. But once you are placing regular, growing orders with a supplier, this is one of the first points that can move: free domestic shipping above a volume threshold, or the supplier absorbing it when order value is high enough.
When you are comparing two suppliers with nearly identical unit prices, domestic shipping often determines the actual price difference. A supplier in Guangdong shipping to a Guangdong consolidation warehouse typically costs meaningfully less on this leg than a supplier in Hangzhou or Qingdao shipping to the same warehouse. Distances inside China are not short, and that shows up in the number.
How it connects to international freight
Domestic shipping and international freight are separate costs and need to be tracked separately, but they are connected in one way worth knowing.
International freight is usually calculated from the consolidation warehouse to your receiving location. Goods arrive at the warehouse in their original factory packaging, and the warehouse typically repacks before dispatch. The packed weight and volume that leaves the warehouse can differ from what left the factory. If the warehouse adds cushioning or uses a larger outer carton, the volumetric weight increases and so does the international freight charge. This is a separate line item from domestic shipping, but it sits in the same cost chain you need to track completely if your landed cost number is going to be accurate.
Bottom line
Domestic China shipping will not wreck a business on its own, but it is the cost most consistently left out of landed cost calculations. Ask for the rate before you order, add it to the yuan-denominated cost before converting, and ask for itemized invoices from your agent. Get the landed cost right and the decisions that follow it will be right too.
