Screen goods for export-control restrictions to a destination country.
Combines the goods classification with the destination's restriction status
and returns whether a license is required, the risk level, applicable
license policies (e.g. presumption of denial), control reasons (NS, MT, NP,
CB, AT), and proliferation/dual-use flags. Identify the goods by ANY of:
ECCN, HS code, or a free-text description (English or Russian).
IMPORTANT — jurisdiction nexus: each jurisdiction's controls only bind a
payment/shipment when there is a nexus to that jurisdiction (US EAR binds
US persons, USD-clearing, and US-origin items; EU/UK/JP bind their persons,
currencies, and origin). Use jurisdiction="ALL" for a comprehensive
multi-jurisdiction view, or pick the one matching the actual touchpoints.
IMPORTANT, prefer eccn or hs_code: goods_description is a fallback: the
classifier matches it lexically, so a vague description still returns one
specific HS code and it is usually the wrong one ("industrial machinery"
returns bakery and pasta machinery). When you pass a description only, the
result carries classification_basis and classification_confidence_note;
read them, never quote the inferred code back to the user as their HS code
or ECCN, and ask for the code on their invoice or export declaration. The
destination findings (embargo, transshipment risk, screening duties) are
NOT affected by that doubt, so report them normally.
Args:
destination_country: ISO 3166-1 alpha-2 destination code (e.g. "RU", "CN").
eccn: Optional Export Control Classification Number (e.g. "3A001").
hs_code: Optional Harmonized System code, 4-8 digits (e.g. "854231").
goods_description: Optional free-text goods description (EN or RU).
jurisdiction: "US" (default), "EU", "UK", "JP", "ITAR", or "ALL".
Provide at least one of eccn / hs_code / goods_description.
Examples:
export_controls_screen("RU", eccn="3A001") # electronics → Russia
export_controls_screen("CN", eccn="3A090") # advanced computing → China
export_controls_screen("IR", goods_description="industrial valves")
export_controls_screen("RU", goods_description="drone", jurisdiction="ALL")
export_controls_screen("DE", hs_code="854231") # → Germany (allied)
Use case: 'Can we ship integrated circuits to Russia?'
