Timber Material OEM Custom Sizes Service: What to Clarify Before Ordering
A practical guide to sourcing custom timber sizes from an OEM supplier — covering MOQ, tooling, lead time, and quality consistency
If you're specifying non-standard timber profiles — unusual widths, extra thicknesses, or custom tongue-and-groove details — you need an OEM supplier who can deliver consistent dimensions across the production run. Timber material that looks right on the first piece but varies by 1.5mm by piece 200 will cause installation delays and site rejection.
We manufacture custom timber profiles for distributors and project contractors. Here's what to clarify before signing an OEM agreement.
MOQ (Minimum Order Quantity): What's Realistic
- New tooling required: Most OEM suppliers require 500–1,000 m² minimum for a new profile. Below that, the tooling amortization makes the unit price uncompetitive.
- Existing tooling (modification): If you're adjusting an existing profile, MOQ can be lower — typically 300–500 m². The supplier's ability to modify existing tooling affects this.
- Repeat orders: Once tooling is amortized, subsequent orders can often be smaller. Clarify the reorder MOQ in the initial agreement — some suppliers reset it after 12 months.
Keep in mind: For modified timber, tooling wear is faster than for untreated timber because of the higher density. Ask how often the supplier re-sharpens or replaces tooling — it affects dimensional consistency across a production run.
Lead Time Reality for Custom Sizes
OEM Custom Sizes Timeline (Typical)
- Sampling (0–2 weeks): Supplier provides CAD drawing for approval, then 1–2 sample pieces. Allows dimensional verification before full production.
- Tooling production (2–4 weeks): New knives, rollers, or模具 fabrication. This is the critical path — delays here shift everything else.
- Production (2–6 weeks): Depends on order volume and factory load. Modified timber adds 1–2 weeks for the heat treatment cycle after machining.
- QC and packaging (1 week): Dimensional audit, moisture content check, and ISPM 15 palletization for export.
Dimensional Tolerances: What to Write into the Contract
For custom profiles, always specify tolerances in the purchase order — not just "as per sample." Here are the typical tolerances for machined timber profiles:
| Dimension | Typical Tolerance | Acceptable for Installation |
|---|---|---|
| Thickness | ±0.3 mm | Yes — allows for sanding/finishing |
| Width | ±0.5 mm | Yes — within tongue-and-groove engagement range |
| Length | +0 / −5 mm | Yes — end-trim during installation is standard |
Our timber profiles for windows and doors are produced with CNC-controlled machining that holds ±0.2mm on critical dimensions — because window/door profiles have zero tolerance for sloppy fit.
