Researcher synthesis
Use the explainer for navigation, but use the current regulation for exact legal wording. Its permissive container-shape example should not override current barrel terminology.
Regulatory comparison: No access and 27 CFR 5.143, checked September 6, 2026.
Assessment
The article uses BAM summaries; current 27 CFR 5.143 specifies barrels. NAS and finished-product conclusions require their applicable labeling provisions, not extrapolation.
No new legal Zettel from secondary shorthand. Link exact current regulatory citations when drafting.
