Building code spec flagging (IRC, IBC, NFPA, ASTM) per SKU, can Magento handle it?

Yes, via product attributes + faceted navigation. The pattern:

• Per-SKU code attributes, code_irc (IRC 2018 / IRC 2021 / both), code_ibc (IBC compliance level), code_nfpa (NFPA 13 fire-rated, NFPA 70 NEC for electrical), code_astm (ASTM spec numbers like ASTM A615 for rebar grades).
• Faceted navigation on category pages, filter rebar by ASTM A615/A706, grade 40/60/75/100, diameter, length. Filter drywall by fire-rating (Type X, Type C), thickness, edge profile. Filter wiring by NEC compliance, conductor count, gauge, jacket rating.
• Code-pack PDFs, PDF spec sheets uploaded per SKU, downloadable from PDP. Required for engineer/architect/inspector signoff on commercial jobs. Hosted on S3/Cloudflare R2 for fast delivery.
• Code-jurisdiction filtering, advanced. Some products are legal in CA but not in NY (e.g. certain flame-retardant chemicals). Use customer-shipping-state to gate product visibility. Implemented as a stock-source-selection rule + product attribute.

The audience: architects, engineers, and code inspectors use the website as a spec-confirmation tool more than a purchase tool. They search by ASTM number, download the spec sheet, and forward it to the contractor with the SKU. Your job is to make that flow frictionless. The contractor then logs in (already a customer) and buys the SKU.

SEO bonus: indexing on ASTM/NFPA spec numbers ranks well because the search volume is real (architects google “ASTM A615 grade 60 #5 rebar”) and Home Depot Pro doesn’t optimize for it.
