completedcode_genP1

Description

Build Australian Customs Tariff classification engine following uk_tariff.py pattern. TEMPLATE: rosetta_core/uk_tariff.py DATA SOURCE: Australian Border Force tariff classification. Try ABF API or use HS-6 pivot with chapter-level rates. SYSTEM: Australian Harmonized Tariff (8-digit AHECC for exports, 12-digit statistical for imports). ABF authority. TAX: GST 10% flat (no state variation). Import Processing Charge (IPC) ~$50 per declaration. FTAs: AUSFTA (US), AANZFTA (ASEAN+NZ), ChAFTA (China), JAEPA (Japan), KAFTA (Korea), UK-Australia, CPTPP, RCEP. DUTY: General rate + preferential rates per FTA. No Section 301 equivalent. FILES TO CREATE: 1. rosetta_core/au_tariff.py — classify_au() with HS-6 pivot 2. rosetta_core/au_duty.py — duty + GST calculator 3. tests/test_au_tariff.py — 15+ tests 4. Wire into multi_jurisdiction.py (add AU to JURISDICTIONS + dispatcher)
