FSC chain-of-custody vs. per-member provenance — what's the difference?

Q: FSC chain-of-custody vs. per-member provenance — what's the difference?

FSC chain-of-custody certifies an operation (a mill or supplier) through periodic paid third-party audits and is built for volume and forestry sustainability claims. Per-member provenance certifies an individual reclaimed piece — its source, dimensions, and custody history, verifiable by the buyer without an auditor. They answer different questions at very different costs and are often complementary rather than mutually exclusive.

Short answer: FSC certifies an operation (a mill or supplier) through periodic third-party audits, and is oriented to volume and forestry sustainability. Per-member provenance certifies an individual piece — this beam, its source and custody, verifiable by the buyer. Different jobs, different costs. Many dealers treat them as complementary rather than either/or.

These get lumped together because both have "chain of custody" in them, but they're solving different problems. Confusing them leads people to think they need one when they want the other.

What FSC certifies

Forest Stewardship Council chain-of-custody certification is about an operation. A mill, distributor, or manufacturer pays for periodic third-party audits proving they can track certified material through their process and keep it separated from uncertified stock. It's aimed at sustainability sourcing and works at volume. It's real and valuable — and it's built for suppliers moving a lot of wood, with the cost and audit overhead that implies.

What per-member provenance certifies

Per-member provenance is about a piece. Not "this company handles certified wood correctly," but "this specific beam came from here, measures this, and its custody is recorded and verifiable." It's issued per timber, checkable by the buyer, and priced to make sense on individual reclaimed pieces rather than truckloads.

Side by side

Unit: FSC = the operation. Provenance = the individual piece.
Who checks: FSC = a paid auditor, periodically. Provenance = the buyer, anytime, themselves.
Cost shape: FSC = ongoing audit/membership overhead. Provenance = per-piece, no audit.
Answers: FSC = "is this sourced sustainably and tracked?" Provenance = "is this specific reclaimed piece what the seller says, and where's it from?"

Not a competition. A supplier can be FSC-certified and issue per-member provenance — they're answering different buyer questions. If your buyer cares about sustainable sourcing at volume, that's FSC territory; if they care whether this antique beam is genuine and traceable, that's provenance.
