You Bid Plywood in March and Buy It in September
Your panel goods, hinges, and slides were priced at bid and bought a quarter or two later, and since 14 October 2025 a duty layer sits on top of that delay.
A sub that mobilizes the week it's awarded buys close to bid pricing, because only days separate the two. Millwork can't buy until drawings are approved, which makes this trade's exposure window structurally longer than almost anyone else's on the job. The tariff line points straight at HTSUS 9403 cabinets, vanities, and their parts, which is the product coming off your floor.
The size of it
You carry the whole price move on panel goods and hardware between bid and buyout, on a job you may not fabricate for two quarters. On a material-heavy package a single-digit move in sheet pricing can take the job's profit before you cut anything.
No published benchmark reference breaks this trade out on its own. CFMA reports at NAICS level, and at that level this trade rolls into a broader bucket with several others. That's why this page carries mechanisms and no margin figures. It reports inside NAICS 238350 Finish Carpentry, so there's no millwork and casework margin figure to put in this box. The 48 trades that do publish average 7% net profit at $1M–$5M before taxes, which is the nearest reference point worth anything here.
The approval gate sits between award and buyout, so a millwork shop's real material buy routinely comes three to six months after the number you submitted. Section 232 duties took effect 14 October 2025 at 25 percent on kitchen cabinets, vanities, and their parts under HTSUS 9403, with the step to 50 percent deferred to 1 January 2027. Hardwood plywood, imported hinges, slides, and closers all sit inside that exposure. Hard bid millwork subcontracts almost never carry escalation language, so the entire move is yours to eat.

What millwork and casework owners ask
How to protect a millwork bid when material buyout is months after the bid date?
Your panel goods, hinges, and slides were priced at bid and bought a quarter or two later, and since 14 October 2025 a duty layer sits on top of that delay.
What does it cost?
You carry the whole price move on panel goods and hardware between bid and buyout, on a job you may not fabricate for two quarters. On a material-heavy package a single-digit move in sheet pricing can take the job's profit before you cut anything.
What do I do first?
Date-stamp every supplier quote in the estimate file and write the expiration next to it, so you know which lines are exposed before you sign a subcontract.
Are there published benchmarks for millwork and casework?
No, and this site won't print one. No published benchmark reference breaks this trade out on its own. CFMA reports at NAICS level, and at that level this trade rolls into a broader bucket with several others. That's why this page carries mechanisms and no margin figures. In the surveys it rolls into NAICS 238350 Finish Carpentry, so the closest honest reference is the 48-trade table, where net profit at $1M–$5M averages 7% before taxes. Read that as the neighbourhood, and read your own job costing as the answer.
Which part of the system fixes it?
The step is number 04, estimating system. The estimate maps one to one onto the job cost codes, so variance means something the day it appears. It comes from chapter 4 of CONTROL: The Construction Financial Operating System.
Josh Luebker ran commercial construction projects before he ran the numbers behind them, on data centres, military bases, hospitals, and high-rises. He wrote CONTROL: The Construction Financial Operating System, which is an eight-step framework for commercial subcontractors, and it publishes on October 1, 2026. He is a master electrician who moved into the office and kept the field vocabulary.
Sulphur Prairie Operations LLC maintains the benchmark reference behind these figures. Every edition is reconciled against the newest CFMA survey release before it publishes here. Where a figure changes between editions, the older edition keeps its year in the title so a citation to it stays correct.
