The range is the product
Nobody buys one plastic storage box from a Chinese factory and stops there. A houseware buyer — a supermarket, a discount chain, a home-goods distributor — buys a kitchen line, a storage line and a bathroom line that have to look like they came from the same brand, sit on the same shelf and share a colour card.
That changes the sourcing problem completely. Instead of optimising a single unit price, you are optimising tooling spread across 30 to 80 SKUs, colour consistency across three material families, and a container that mixes all of it without exceeding weight or cube.
Most first orders in this category go wrong on exactly those three points, and none of them appear on a quotation sheet.
Tooling economics across a range
Every SKU needs a tool. A small bathroom item might be a single-cavity tool; a 55 L storage box is a large deep-cavity tool with a much longer cycle. The per-unit tooling charge in a quote is simply the tool cost divided by the volume you commit to, so the same tool can appear as 2 percent or 20 percent of unit price depending on the order.
| SKU class | Typical tool cost band | Economic order quantity |
|---|---|---|
| Small bathroom item (soap dish, holder) | Low | 3,000–5,000 pcs |
| Kitchen smallware (strainer, cup) | Low to medium | 3,000–5,000 pcs |
| Mid-size storage (10–30 L) | Medium | 1,500–3,000 pcs |
| Large storage (50 L and above) | High | 500–1,500 pcs |
| Multi-part assemblies (rack, caddy) | Medium × parts | 2,000–4,000 sets |
Two commercial rules follow from this table.
First, do not tool the whole range at once. Tool a hero SKU per line, sell it, then use the revenue to fund the next tier. A range of 60 SKUs tooled simultaneously is 60 bets placed before any of them has a sales history.
Second, negotiate tooling ownership explicitly. Who owns the tool, where it is stored, and what happens if you move to another supplier. A tool that stays in the factory by default is leverage you have given away. Ask for a tool inventory with cavity counts and tool numbers, and a written statement of ownership.
Colour consistency is harder than it looks
The same Pantone reference will not look the same across PP, ABS and TPE. Three reasons:
- Base resin colour. PP homopolymer is slightly yellow; copolymer is slightly bluer. The same masterbatch dose gives a different result.
- Wall thickness. A 1.2 mm wall and a 2.8 mm wall of the same coloured PP read as two different shades, because more material absorbs more light.
- Surface finish. A textured face scatters light and appears lighter than a polished one.
The practical fix is to approve colours per substrate and per finish, not per brand colour. Send the supplier a physical reference for each material family, approve a moulded plaque rather than a colour chip, and keep the approved plaque as the standard for reorders. Colour drift between the first order and the third is one of the most common complaints in this category, and it is nearly always traceable to a plaque nobody kept.
For a range that must look unified, specify that all SKUs in one line use the same masterbatch supplier and the same dose, and accept that the ABS parts will be a half-shade off the PP parts. Designing the range so that mixed-material parts are not adjacent on the shelf removes the problem entirely.
Mixed containers: cube beats weight
Houseware is bulky and light. A 40 HQ container holds about 68 m³, and a houseware range will cube out long before it reaches the 26-tonne weight limit.
That has two consequences:
- Nesting is a design requirement, not a packaging detail. A storage box that nests 2:1 ships twice as many units per container as one that does not. This single ratio can move landed cost by 20 percent.
- The mix has to be planned against cube, not against value. A container full of soap dishes is cheap to fill and expensive per cubic metre. A container that mixes large nesting items with small dense items uses the cube better.
Ask every supplier for units per carton, carton dimensions and gross weight, then build the container plan from those figures. Suppliers who quote only FOB price per piece are giving you a number you cannot compare.
Quality control across a mixed range
A 60-SKU order cannot be inspected SKU by SKU at full AQL. The workable approach is a two-tier plan:
- Critical SKUs (the ones carrying the range, highest volume, highest return risk): full AQL inspection, dimensional report, and a functional test — load, drop, seal or drainage depending on the product.
- Filler SKUs: visual and dimensional check on a reduced sample, plus a packaging check.
Write the inspection plan into the purchase order. A factory that knows which SKUs will be measured measures them.
Compliance is per market, not per product
The same houseware range can require three different compliance packages:
| Market | Main requirements for food-contact houseware |
|---|---|
| EU | EU 10/2011, declaration of compliance, migration testing |
| US | FDA 21 CFR 177.1520 for polyolefins, plus state-level chemical rules |
| China domestic | GB 4806 series |
Non-food items (storage, bathroom) have no food-contact requirement but do fall under general product safety rules and, in the EU, toy-adjacent rules if the product is marketed to children. A storage basket sold as a toy bin is a different compliance category from the same basket sold as laundry storage — the intended use stated on the packaging decides it.
RFQ checklist for a range
- SKU list with target volumes per SKU, and which SKUs are hero items.
- Colour card, split by material family, with approved moulded plaques.
- Nesting ratio and pack density per SKU.
- Tooling cost, ownership, storage location and cavity count per tool.
- Container plan: target cube utilisation and total order value.
- Inspection plan by SKU tier, with the functional test named for each.
- Compliance package per destination market.
- Reorder lead time and the MOQ per SKU after the first order — this is often different from the first-order MOQ and is the number that governs your replenishment.
The one number to ask for last
Ask for the landed cost per cubic metre of shelf-ready product, not the FOB price. It combines unit price, pack density, carton cube and the container mix into a single figure that can be compared across suppliers.
In houseware, that number explains more pricing differences than the resin market does — and unlike the resin market, it is something the supplier can actually change for you.
