Packing Methods to Cut Costs on Shipments from China

Short answer: good packing protects the goods and reduces chargeable volume, but over-packing raises cost. Use cartons strong enough for the weight, fill voids, secure goods on pallets, mark shipping details clearly, and agree packing standards with the supplier in writing before production.

1. Primary packaging (the product itself)

A bag or box protecting against dust, moisture and scratches.
Dividers or foam for fragile parts.
A simple test: does the product survive a low drop inside its box?

2. Outer packaging (cartons)

Choose carton strength suited to the weight; weak cartons collapse when stacked.
Do not exceed the recommended weight per carton so it can be handled.
Seal cartons with strong tape on edges and openings.
Use strapping for heavy bundles.

3. Pallets and loading

Wooden pallets ease handling but add volume and weight.
Some countries require wood treatment (heat or fumigation) and an approved ISPM 15 mark; check your destination's requirements.
Stretch-wrap the pallet to hold cartons in place.

4. Reducing cost through packing

Reduce empty space to cut chargeable volume.
Match carton dimensions to pallet or container dimensions.
Standardise carton sizes where possible.
Agree with the supplier whether packing is included in the price.

5. Marks and documents

Write the consignee, order number and carton count.
Add orientation and fragile marks where needed.
Make sure the packing list matches what is in the cartons.

6. Packing by cargo type

Fragile (glass, ceramics): cushioning, dividers and double-wall cartons.
Electronics: anti-static materials and moisture protection.
Heavy goods: reinforced cartons or wooden crates.
Clothing and fabric: sealed bags that protect against moisture.

Example: how better packing saves money

Example with assumed figures, for illustration only: a product currently packed in a carton of 50×40×30 cm, or 0.06 CBM per carton, holding 10 units. 200 cartons equal 12 CBM. If the carton could be reduced to 45×35×28 cm with adequate protection, it becomes about 0.044 CBM per carton and 8.8 CBM for 200 cartons. At an assumed LCL rate of USD 90 per CBM, this saves about USD 288 per batch. Not every product allows this reduction, so test a sample before adopting the new packing.

Simple tests of packing strength

Drop test: drop the packed carton from about a metre onto its faces and corners, then inspect the contents.
Stacking test: place a suitable load on the carton for hours and watch for deformation.
Humidity test: make sure carton and contents tolerate a humid environment if the route is by sea.
Basic vibration test: shake the carton and check that the contents do not move or rub.

Packing for air and express

Air and express are usually charged on volumetric weight, so large cartons with empty space raise cost. Use the smallest carton that protects the product, limit heavy filling material, and make sure the gross carton weight is within the carrier's limits.

Agree packing specifications with the supplier in writing

Carton type, number of plies and dimensions.
Units per carton and how they are arranged.
Mark text and barcode if any.
Inner packing and protection method.
Whether the price includes packing, and what happens if goods arrive damaged because of packing.
Photos of packing before closing and of pallet loading.

Common packing materials and when to use them

Corrugated cardboard in different plies: the basis of outer packing; choose plies according to weight.
Bubble wrap: protection against shocks and scratches for light and medium items.
Foam and polyethylene foam: cushioning for devices and fragile products.
Paper fill: filling voids at low cost.
Moisture-barrier bags or absorbent materials: for sensitive goods.
Strapping, strong tape and edge protectors: securing cartons and pallets.

Retail packaging versus shipping packaging

Packaging for the consumer (the box and labels) differs from shipping packaging (outer cartons). Do not rely on an attractive product box to protect it in transit. Agree the inner box and the outer carton separately with the supplier and ask for a sample of both before full production. If your product will carry your own brand, agree printing, logo and colours in the same order.

Pre-shipment photos

Ask the supplier for photos of several packed cartons opened, of pallet loading, of outer labels, and of the container before it is closed. These photos are not a luxury: they are your evidence if the goods arrive damaged and you need to establish the cause, whether packing or transport.

Standard or custom packing?

Standard cartons are cheaper and quicker; packing custom-made to the product's shape protects better and sometimes reduces volume, but adds cost and production time. For large quantities the volume saving may offset the customisation cost; for small quantities good standard packing is usually enough.

A checklist before closing cartons

Is the product fixed in place in the carton and does it not move when shaken?
Are voids filled without excess pressure on the product?
Is the carton sealed well on the base and lid with enough tape?
Has a contents slip or inner label been added if needed?
Are weights and dimensions recorded accurately for the packing list?
Does the outer label show the consignee, order number, carton count and any special marks?

Packing mistakes that lead to damage

Using weak, reused cartons.
Overfilling the carton so the lid distorts.
Leaving voids that let the product move.
Placing heavy items on top of fragile ones inside the carton.
Not protecting the corners and edges of sensitive products.
Neglecting moisture protection for sea shipments.

Frequently asked questions

Does extra packing raise freight cost? It may add a little weight and volume, but it can save damage losses. Balance the two according to the goods' value.

Should I leave packing to the supplier? You can, but write the specification into the purchase order and ask for loading photos before shipment.

Does packing affect insurance? Yes, poor packing is a common exclusion in cargo insurance policies.

Can the goods be packed with my own branding? Yes, provided design, quantity and cost are agreed with the supplier before production.
