Why the minimum follows the color, not the order
The first thing to understand about panel minimums is that they are not about volume for its own sake. Each color on a veneered, fluted or slat line is its own production run: a separate staining or pressing setup, a separate batch of face material pulled toward one standard, and a separate lot that must match the retained swatch under a standard lamp before it packs. The plant's risk sits in that setup, and the minimum exists to cover it. Two colors at 150 sq m each are a different manufacturing job from one color at 300 sq m, even though the total area is identical - which is why minimums are quoted per color and why the question that matters for a program is area per color, not order size alone. It is also why repeat colors are the soft spot in any minimum: the setup is proven, the standard exists, and the run only has to match the swatch it created.
Estimating area per color honestly is therefore the first OEM skill. The working method is to measure the walls the range will actually cover, add the cutting margin the format forces - profile panels and mosaic modules both generate offcuts at corners and sockets - and then add the spares a program wants in the box: a few panels per color for installer errors and later repairs, so a year-three patch comes from the original batch rather than from an almost-match. The number that survives this arithmetic is the one to plan minimums against. A range planned on raw wall area meets its minimum twice - once in production, once in the argument about who pays for the shortage.
The reference ranges by line
Across the category, minimums are quoted as typical reference ranges - planning figures, confirmed in writing for each program before they harden into commitments. The ranges by line:
| Line | Typical reference minimum |
|---|---|
| Veneered wall panels - fluted and flat faces | From 100-300 sq m per color |
| Acoustic slat panels | About 100-200 sq m |
| Mosaic wood panels | 100-200 sq m |
| WPC wall panels | 300-500 sq m, or ordered per piece |
| Veneer sheets and rolls | 500 sq m per color |
| Mounting rails and battens | By the thousand pieces, or per kilometer |
| Edge banding and trims | By the thousand pieces |
Read the table as the trade's common ground, not as a price list and not as a floor: plants flex on repeat colors, on programs that consolidate volume, and on runs that fit an existing schedule - but every exception is a per-program conversation answered in writing. The same ranges, with the sample and batch timing beside them, sit on the MOQ and lead time page.
What molds and tooling change
Profile work adds a second axis to the minimum conversation: tooling. Catalog fluted and slat panels run on cutters the plant already owns, which is why catalog pitches ship at catalog minimums and catalog pace. A private geometry - a slat width or pitch of your own, a flute radius from a drawing, a mosaic figure nobody else runs - is a tooling decision: cutters or dies are made, a sampling cycle proves the profile, and the production minimum for that profile sits higher than the catalog equivalent. Tooling is also an ownership question that belongs on the program sheet rather than in an email thread: on an OEM program, the drawing and the cutters are assigned to the buyer and confirmed in writing, so a second plant cannot simply run the same profile and a reorder does not renegotiate its own existence. The branding ladder - from printed cartons to private profiles - is walked on the OEM and private label page, and the route division between buyer-held and plant-held designs is compared in the OEM versus ODM note.
What colors do to a program
Colors carry the second cost: time. Catalog tones start at production because the formula, the standard and the retained swatch already exist. A custom color inserts a proofing loop - a target agreed as a physical sample, a first article produced, judged in daylight and under a lamp, approved and frozen - typically 15-25 days before the run, with the first batch carrying that color typically 45-60 days against 25-45 days for catalog colors. Color count then multiplies the effect: minimums are per color, so a range spread thin across many tones hits each one hardest. The planning answer is the color ladder - a few core tones with depth, seasonal accents on top - which the color planning note architects in detail. A three-color first range on one line pools sampling, tooling and freight in a way three separate single-color orders never will.
The OEM sequence around the numbers
Minimums and tooling make sense only inside the sequence they serve. The brief fixes family, colors or physical targets, area per color and destination. The desk shortlists partner plants per line, and sampling runs in stages: color cards typically 5-10 working days, production-format panel samples 7-15, a custom color article 15-25 days. The approved sample is retained as the swatch that governs every later lot, and grade documents are collected before production - certificates per lot for the emission grade the market reads, fire reports where a rating is quoted, matched to the build-up actually shipped. Only then does the batch run against the program sheet, with minimum per color, tooling ownership, packaging and lead all confirmed in writing on that one sheet. The full walk is on the sourcing process page.
Planning a range inside the minimums
Three habits keep a range comfortable inside the numbers. First, plan the ladder before the first order: decide which tones are core, which are accents, and which can wait a season, so area concentrates where it earns depth. Second, remember that minimums do not pool across lines - three colors spread across two lines is five runs, not two - but one container can still carry several lines, which is a freight plan rather than a production fiction; the arithmetic sits in the container planning note. Third, treat repeat colors as the flexible edge of the range: when a tone proves itself, the reorder conversation has a standard to stand on. When the area per color and the color list are ready, the quote form turns them into a program sheet with the minimums, the tooling position and the timing on it - confirmed in writing before anything runs.
