EAEU industrial-input tariff liberalisation

Paired Eurasian Economic Commission Collegium (technical/administrative tier) and Council (ministerial tier) decisions that narrow existing Common Customs Tariff commodity codes to carve out a duty-free or reduced-duty sub-line for a specific domestic end-use industry, rather than granting a direct subsidy. Distinct from russia-counter-sanctions-import-substitution (unilateral Russian domestic law responding to Western sanctions) and from the EAEU/EEC trade-remedy track (e.g. the titanium-dioxide anti-dumping decision, which raises duties against a named third country): this theme is EAEU-internal, non-adversarial tariff engineering aimed at lowering input costs for bloc manufacturers.
