Packing Bulky 1688 Goods to Cut Freight

Bulky goods from 1688 have a habit of eating margin at a point most sellers overlook: freight is charged by volumetric weight, not actual weight. This piece covers how to ask suppliers to disassemble, compress, or repack items so the freight bill back to Vietnam is meaningfully smaller than the default.

Why bulky goods cost far more to ship than expected

When you import a 2-kilogram item that happens to be large, the carrier does not necessarily charge you for 2 kilograms. They charge for volumetric weight, which converts the box dimensions into a kilogram equivalent. The standard formula is: length x width x height (in centimeters) divided by 6,000, giving kilograms.

A folding chair that weighs 1.5 kilograms but ships in a 60x50x40 cm box has a volumetric weight of: 60 x 50 x 40 / 6,000 = 20 kilograms. Carriers bill whichever is higher, actual or volumetric. For bulky goods, volumetric wins almost every time, and you pay for 20 kg instead of 1.5 kg.

This is why a product with an attractive 1688 price can land at break-even or a loss once freight is added. You did not miscalculate the product cost. You skipped the volumetric step when estimating shipping.

Request disassembly before packing

This is the highest-impact tactic for several product types. Many 1688 suppliers pack goods fully assembled because that is how they ship to domestic Chinese buyers. If you ask, many will ship in disassembled or flat-pack form instead.

The product types that benefit most:

• Tables, shelves, and cabinets with multiple panels. Flat-pack collapses height from 80 cm down to 15 or 20 cm, cutting volumetric weight sharply.
• Chairs, folding chairs, office chairs. Removing legs and laying them flat alongside the seat cuts the box width immediately.
• Framed sports goods: bicycles, strollers, gym frames. Removing wheels, handlebars, or frame sections reduces the box size considerably.
• Lamps, fans, and stands with vertical poles. The upright post is usually what drives box height.

When messaging the supplier, explain clearly that the goal is to reduce box size for international freight. Most factories understand the request and will accommodate it, sometimes for a small extra packing fee (typically a few yuan per unit, if anything at all).

Ask for volume compression on soft goods

Fabric goods, cushions, pillows, backpacks, and bags are easy to overlook because they are light. But a cotton pillow or seat cushion can take up a disproportionate amount of box space if the supplier packs it uncompressed.

Options worth requesting:

• Vacuum packaging. Cushions, pillows, lightweight blankets, and medium-sized stuffed toys can all be vacuum-sealed, cutting volume by 60 to 70 percent. Most suppliers have vacuum equipment on site, and the added cost is small.
• Bale compression with strapping. For fabric, garments, or towels shipped in larger lots, ask the supplier to compress the bale and secure it with plastic or steel strapping rather than leaving air space inside a loose carton.
• Rolled instead of folded. Some rugs and fabric rolls have a much smaller volumetric footprint when rolled tightly and wrapped than when laid flat inside a square carton.

One important note: after vacuum sealing or compression, the carrier still measures the outer packaging, not the product inside. So the outer box itself must also be kept compact. Leaving excess air space in the carton wastes the compression gains.

Consolidate and repack at a China warehouse

Another way to reduce total volume is consolidation, where multiple smaller shipments from several suppliers are received at a warehouse in China, then repacked into a smaller number of optimally sized boxes before the international leg.

Consolidation warehouses typically offer:

• Opening original cartons and repacking to a requested dimension.
• Combining small items from multiple orders into a single carton.
• On-site vacuum sealing if you request it and the products are suitable.

Before using a consolidation service, ask about fees upfront: receiving fees, repacking fees, and storage fees if you are waiting to accumulate enough stock for a combined shipment. These costs go into your landed cost calculation. That said, if you save a meaningful amount on freight per large shipment, the warehouse fee usually pays for itself.

Estimate freight under both scenarios before ordering

Before placing an order, build a rough freight estimate for two versions: standard packing and optimized packing.

1. Ask the supplier for box dimensions and actual weight under standard packing. Most have these on hand.
2. Calculate volumetric weight: length x width x height (cm) divided by 6,000.
3. Take the higher number between actual weight and volumetric weight to estimate freight. Sea freight from China to Vietnam typically takes around 18 to 30 days depending on route and port. Ask your current carrier for per-kilogram or per-CBM rates, as these vary.
4. Ask the supplier for revised dimensions if disassembly or repacking is applied. Recalculate freight on the new numbers.
5. Compare the difference against any additional packing cost to see if the saving is net positive.

A simple worked example: a folding chair in a standard 60x50x40 cm box weighs 1.5 kg, volumetric weight 20 kg. Assuming a road-freight rate of around VND 15,000 per kilogram: freight cost is roughly VND 300,000. Disassembled into a 60x20x15 cm box, volumetric weight drops to around 3 kg: freight cost falls to roughly VND 45,000. Difference: about VND 255,000 per unit. On a batch of 50 chairs, that is more than VND 12 million saved on freight alone.

These numbers are illustrative. Actual rates depend on your carrier, the route, and the season. The point is to run the comparison before you commit, not after the stock lands.

When disassembly does not make sense

Not every bulky product is worth disassembling. Cases where it is not practical:

• Electronics and motorized appliances where disassembly voids warranty or makes reassembly unreliable.
• Fragile goods such as ceramics or glass: disassembly may increase breakage risk during reassembly, and the trade-off between freight savings and defect cost needs to be weighed.
• Factory-sealed goods where opening the box to disassemble removes the seal and affects presentation at point of sale.
• Small batches under ten units: consolidation and repacking costs may exceed the freight saving at low volumes.

In these cases, the practical move is either choosing the right shipping route (sea freight over road for high-volume bulky items), or accepting the freight cost and building it correctly into landed cost from the start rather than discovering it later.

Record dimensions so you do not recalculate every time

A small but recurring cost: not keeping the numbers from the last shipment. For each bulky SKU, store:

• Box dimensions (length x width x height), both standard and optimized where applicable.
• Actual weight.
• Corresponding volumetric weight.
• Which packing method is in use (disassembled, vacuum-sealed, consolidated).
• Any additional packing fee charged by the supplier.

With this on file, estimating freight for the next reorder takes a few minutes, not a round of back-and-forth messages with the factory.

Bottom line

With bulky goods, freight is not a fixed input. It is something you can affect if you ask the right questions at the right time. Disassembly, volume compression, and consolidation are three practical levers for cutting volumetric weight and the freight bill that follows. Calculate freight by volume during product evaluation, before the order is placed, so there are no surprises when the stock arrives and the margin has already been spent on shipping.
