Customs & Tariff Management

Harmonized System (HS) Code Classification:

# HS Code Classification Logic

def determine_hs_code(product_description, product_attributes):
    """
    Determine appropriate HS code for customs classification
    """
    # HS Code structure: XXXX.XX.XX.XX
    # Chapter (4 digits) -> Heading (2 digits) -> Subheading (2 digits) -> Statistical suffix (2 digits)

    classification_rules = {
        'textiles': {
            'chapters': [50-63],  # HS chapters for textiles
            'factors': ['material_composition', 'weight', 'weave_type']
        },
        'electronics': {
            'chapters': [84, 85],  # HS chapters for electronics

        },
        'automotive': {
            'chapters': [87],  # HS chapters for vehicles
            'factors': ['vehicle_type', 'engine_size', 'passenger_capacity']

    # Classification logic using product attributes
    # Returns HS code and applicable duty rates

Free Trade Agreement Optimization

FTAs and Their Impact:

Agreement	Coverage	Average Duty Reduction
RCEP	APAC 15 countries	90% eliminated over 20 years
USMCA	North America	75% eliminated immediately
EU Single Market	EU 27	100% eliminated
CPTPP	11 countries	99% eliminated over time

Rules of Origin:

• Substantial transformation test
