When you work with a custom planter box factory, the planter box minimum order quantity for custom-size planter boxes is not always a single number. It depends on how much your requested dimensions differ from the factory’s existing molds, standard panel sizes, and production process. For simple dimension changes using stock materials, standard colors, and basic hardware, many factories begin at 100 pieces. That quantity helps cover cutting, assembly setup, quality checks, and packaging without making each unit too expensive.

If your project needs custom colors, special finishes, logo printing, liners, drainage trays, or non-standard joinery, the MOQ often increases to 300–500 pieces. These features require extra setup, samples, testing, and quality-control time. For a fully custom design, new mold, or custom metal or plastic profile, the planter box MOQ may be 500–1,000 pieces or higher because tooling and production planning costs need to be recovered.

Some factories can accept a smaller trial order, sometimes around 50 pieces, if your custom size is close to an existing production size and you choose in-stock materials. Even then, the unit price is usually higher, and a sample or development fee may apply. If you are testing a new market, ask whether that fee can be credited toward a future wholesale planter boxes order.

To confirm the exact minimum, send the factory your length, width, height, material, thickness, color, finish, drainage details, liner needs, logo method, packaging requirements, and target delivery date. Clear specifications help the factory check molds, calculate material yield, and quote accurately. In general, expect about 100 pieces for basic custom sizes, 300–500 pieces for semi-custom orders, and 500+ pieces for fully custom production. Always ask for the final MOQ in writing before you place a deposit.
