Analysis
NAICS 327999 is the 2022 national industry for all other miscellaneous nonmetallic mineral product manufacturing, part of 32799 (All Other Nonmetallic Mineral Product Manufacturing). Census lists 17 example activities under it in the official index.
Census lists 12 related activities that belong elsewhere, most often in 327110, 327120, 32721 and 327310. Businesses that do several things are classified by their primary activity, the one that generates the most value, so check those boundaries before settling on this code.

Its index entries, the activities Census uses to assign businesses to this code, include asbestos products (except brake shoes and clutches)…, asphalt concrete crushing and grinding (except at…, built-up mica manufacturing and ceramic fiber manufacturing, among 17 in all.
Its goods appear in 23 statistical lines of the US tariff schedule, mostly under headings 6811 (articles of asbestos-cement, of cellulose fiber-cement or…), 6812 (fabricated asbestos fibers; mixtures with a basis of…) and 6815 (articles of stone or of other mineral substances (including…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
For example, manufacturing pottery, ceramics, and plumbing fixtures are classified in 327110 (Pottery, Ceramics, and Plumbing Fixture Manufacturing) instead.
