How this service works
Matches declared classification tokens against a supplied published dual-use control list. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age. This is neither legal advice nor customs advice.
Output
Returns matched control entries indicating which candidate codes or commodity description tokens align with supplied control list keywords, along with disclosure of derivation methods, source document metadata, age of data, and a list of unavailable_fields where information could not be determined. Does not constitute legal or customs advice.
Example use cases
Export shipment dual-use screening
“I need to check whether these product codes — 5A002, 3A001, 7A003 — appear on the dual-use control list before we ship next week. The commodity is 'optical fiber sensing equipment for industrial monitoring'. Use the regulation published at https://eur-lex.europa.eu/annex1-2024.pdf on 2024-03-01 with keywords like 'optical', 'fiber', 'sensor', 'accelerometer'.”
Customs classification compliance check
“Can you run our new product's classification codes — ML10, 3E001 — against the dual-use keywords 'encryption', 'laser', 'guidance system' from the Wassenaar control list posted at https://wassenaar.org/controllist2023.pdf on 2023-12-01? The product is a 'compact laser rangefinder for surveying applications'.”
Procurement vendor dual-use risk review
“We're evaluating a supplier's component list. Please match these codes — 3A292, 5E001 — against dual-use control entries with keywords 'frequency converter', 'signal processing', 'military' from the document at https://trade.ec.europa.eu/dual-use-annex.pdf published 2024-06-10. The commodity description is 'programmable signal processing units for avionics testing'.”
Technical details
Endpoint
POSThttps://zoll.halowerk.com/v1/dual-useWhen to prefer
Use this endpoint when you need to programmatically screen classification codes or commodity descriptions against a specific published dual-use control list you supply — particularly when you want transparent provenance (source URL, publication date, derivation method) and explicit disclosure of missing data. Prefer this over general customs APIs when you need to supply your own control list entries and keywords rather than relying on a proprietary database, or when auditability and null-field transparency are important for compliance workflows.
