Six digits is as far as the international nomenclature goes, and it is the same six digits in every country that applies the Harmonized System. Your destination adds further digits of its own, and the rate lives on that national line — which is why the US lines below run to eight and ten digits, and why the lookups go to each authority's own tariff.

US national lines under 4410.12
The United States subdivides this subheading into 3 lines. They share a duty rate, so the classification below the subheading affects reporting rather than the amount.
| Line | Description | General | Preferential |
|---|---|---|---|
| 4410.12.00 | Oriented strand board (OSB) | Free | — |
| 4410.12.00.10 | Unworked or not further worked than sanded | Free stated on 44101200 | — |
| 4410.12.00.20 | Other | Free stated on 44101200 | — |
A blank General cell means the line states no rate of its own and takes the one above it — the line it is stated on is named, so the figure can be checked where it actually appears. Preferential rates are listed with the programme codes that grant them; the schedule offering a rate is not the same as your goods qualifying for it.
Preferential rates for 4410.12
No preference programme applies to these lines for any origin — the general rate is the rate, wherever the goods come from. That is worth knowing: there is nothing to claim here, so no certificate of origin will reduce the duty.
What chapter 44 excludes
A subheading's wording does not decide a classification — the legal notes do. These are the notes that push goods out of this chapter even when the description seems to fit.

4. Products of heading 4410, 4411 or 4412 may be worked to form the shapes provided for in respect of the articles of heading 4409, curved, corrugated, perforated, cut or formed to shapes other than square or rectangular or submitted to any other operation provided it does not give them the character of articles of other headings.

Notes are reproduced from the published tariff schedule. They govern classification, but reading them is not the same as applying them to your goods — that is what a broker or a binding ruling is for.
Other chapters that mention heading 4410
An exclusion pointing into this heading from another chapter is as decisive as one in your own, and it is the one nobody finds by reading their own chapter.
4. Products of heading 4410, 4411 or 4412 may be worked to form the shapes provided for in respect of the articles of heading 4409, curved, corrugated, perforated, cut or formed to shapes other than square or rectangular or submitted to any other operation provided it does not give them the character of articles of other headings.
