Storage is one of the categories buyers assume is easy: plastic, cheap, and made everywhere. It is actually five different supply chains sharing a shelf in the catalogue. A workshop that injection-moulds a drawer divider cannot quote a powder-coated wire rack; the shop that bends that rack cannot quote a wooden jewellery box; and none of them will quote a felt drawer liner, which is a cutting and sewing job. Pick the material first and the shortlist of suppliers falls out of it.
Where the storage lines actually sit
We read 12,951 company records out of public B2B export listings and matched them to product lines. These are the five storage lines in the index, with the provinces that lead each one:
| Storage line | Records | Top provinces |
|---|---|---|
| Storage racks & pegboard | 78 | Guangdong 24 · Jiangsu 19 · Zhejiang 11 |
| Bathroom organisers & tissue boxes | 77 | Guangdong 20 · Zhejiang 15 · Fujian 13 |
| Kitchen organisers & spice racks | 65 | Guangdong 28 · Zhejiang 14 · Shandong 8 |
| Industrial storage & shelving | 58 | Jiangsu 22 · Shandong 17 · Zhejiang 6 |
| Wooden storage & jewellery boxes | 43 | Guangdong 24 · Fujian 7 · Zhejiang 6 |
Basis: the 12,951 records in our index read in September 2026, matched to product lines. A record can be matched to more than one line, so line counts do not sum to a category total. The full category breakdown is on our category data page.
The pattern is not random. Guangdong and Zhejiang appear in every line because they are the general-purpose manufacturing provinces. Jiangsu and Shandong lead the industrial storage line – the heavier, welded, load-bearing end. Fujian shows up in the bathroom and wooden lines, where the work is joinery and finishing rather than moulding. None of that tells you which supplier is good; it tells you which province will recognise your specification when you send it.
What the minimum order quantity really is here
Storage looks like the most commoditised thing on any sourcing site. Its published minimums are not. Comparing the two sets on the same measure – records that publish a minimum counted in pieces – gives this:
| Measure | Home storage | All categories in our index |
|---|---|---|
| Records publishing a piece MOQ | 140 | 4,365 |
| Median | 50 | 1 |
| 25th percentile | 1 | 1 |
| 75th percentile | 300 | 100 |
| Under 100 pieces | 52% | 71% |
Basis: records in our index that publish an MOQ beginning with a number and a piece unit, read September 2026. The storage column uses the same category classification as the home and furniture category page.
The gap between those two columns is a gap between two kinds of product, not between two kinds of seller. A moulded box, a welded rack and a coated frame each carry a setup – a mould, a jig, a coating batch – that a printed item or a bag of loose hardware does not. When a supplier quotes you 500 pieces, that number is usually not a sales policy. It is the smallest quantity at which the setup stops dominating the unit price.
Five material routes, and what each forces you to decide
| Material | What sets the minimum | What buyers forget to specify |
|---|---|---|
| Injection-moulded plastic (PP, ABS, PET) – moulded to shape | The mould, plus a masterbatch minimum for a custom colour | Wall thickness, load rating, and whether stacking was tested |
| Wire, tube and sheet metal – cut, welded, coated | The welding jig and the coating batch | Coating colour and finish, load rating, and who tested it |
| Wood and bamboo – boarded, joined, finished | Board purchase and the finishing batch | Moisture content, finish type, and behaviour in a damp room |
| Textile, felt and non-woven – cut and sewn | The fabric roll and the dye lot | Fabric weight, colour fastness, and whether it is washable |
| Ceramic and glass – cast or pressed, then fired | The kiln batch | Tolerances, and whether the piece is decorative or food contact |
Read the second column as the negotiation, and the third as the specification. Most storage orders that go wrong went wrong in the third column: the material was right, the process was right, and one property nobody wrote down turned out to be the one that mattered.
What to put in the request
- What it stores, and how much weight it will carry when full. This single line changes the material recommendation more than anything else you can write.
- Material and process, if you have a preference – or say that you do not, and ask what the cost difference is between the two obvious routes.
- Dimensions, and whether the size is fixed or the internal volume is what matters.
- Colour: stock or custom, and whether stock is acceptable.
- Quantity, and whether it is a trial or a forecast.
- Market and use: retail shelf, e-commerce, food contact, children’s use.
Where storage orders go wrong
- Comparing a plastic quote with a metal product. Two quotes for “a storage rack” can differ threefold because one is moulded polymer and the other is welded tube. Before comparing prices, confirm both suppliers are quoting the same material.
- Buying by dimension alone. Two racks with the same footprint can differ several times over in how much they hold. The difference is tube gauge, wall thickness and weld quality, none of which is visible in a catalogue photograph. Ask for the load figure and what it is based on.
- Treating a custom colour as free. A custom colour adds a masterbatch or coating minimum on top of the production minimum. On a first order it is usually the single largest avoidable cost.
Freight is part of the design, not a detail afterwards
Storage products are bulky and light. A rack or a stack of boxes fills a container long before it reaches the weight limit, so the cost of moving one unit is driven by volume rather than by material. Two decisions taken at the drawing stage change that more than any material saving:
- Whether it knocks down. A flat-pack rack ships as panels; an assembled one ships as air. The trade-off is assembly at the destination, and the fittings that make the joint hold.
- Whether it nests. Moulded boxes and bins that stack inside one another at a ratio of three or four to one cut the freight per unit by the same proportion – frequently a larger number than the difference between two grades of plastic.
Ask for the carton dimensions and the pieces per carton with the quotation. A unit price without a packing figure is half a landed cost, and the half that is missing is usually the larger one.
The question that saves the most money
Ask for the unit price at three quantities with the same written specification – for example 300, 1,000 and 3,000. Because storage minimums are tooling-led, the curve between those three numbers shows you where the setup is being absorbed, and where more volume stops helping. That curve is also the honest answer to “can you do 300”: yes, at a price that reflects the setup, and here is what it becomes at 1,000.
Two things to do before the deposit
First, buy the sample and test it the way the end user will: load it, wet it, stack it, drop it. A sample that survives being looked at has told you nothing. Second, write the property you care about into the order – load rating, moisture content, fabric weight, coating type – so that the pre-shipment inspection has something to measure against.
Send the specification, not the category
“Storage boxes” is a shelf in a catalogue. A material, a size, a load, a colour and a quantity is a request a factory can price. Send those six lines and you will get a real number and the reason behind it, instead of a minimum that turns out to be a listing figure.
Two pages worth reading next: what a minimum order quantity actually is, and how a quotation is broken into lines on pricing. When you are ready, send the specification through the enquiry form and we will come back with the material route and the quantities it works at.
