tax category
The product's tax classification — the governed external code (Stripe Tax txcd_*, Avalara tax code, Shopify tax_code) that determines which sales/VAT rate applies to it. A product-intrinsic fact (cardinality one): a printed book is the reduced/zero-rated book category, an e-book the standard-rate digital category, basic foodstuffs zero-rated — a classification that travels with the product whoever sells it. A FREE LITERAL, not a governed token vocabulary: the underlying registries publish hundreds (Stripe ~600) to thousands (Avalara) of codes that the pool cannot own or enumerate as natural-language values — exactly the `hs_tariff_code` (HS ~5000-code customs registry) and `trade_identifier` literal-anchor precedent. Its ROLE is distinct from both: `tax_category` classifies the product for SALES/VAT tax; `hs_tariff_code` classifies it for customs DUTY and drives carriage (fulfilment); `trade_identifier` identifies the instance (identity). A non-taxable/exempt product carries its 'nontaxable'/'exempt' category code, so taxability needs no separate boolean (derivable, A10). The applied rate is NOT stored here — it is computed at checkout from this category and the buyer's jurisdiction (downstream, L1/offer).
Tax category is free text, written for one product alone and never shared as a category.
It belongs to tax — one facet of a product.
