How this service works
Calculates customs value under the transaction-value method from disclosed additions and deductions. 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 the computed customs value (or null if insufficient data), a list of unavailable fields that prevented full calculation, and disclosure of the derivation method used. Source-backed figures include source URL, publication date, and age; derived values state their computation method. Does not constitute legal or customs advice.
Example use cases
CIF customs value for air freight
“I need to calculate the customs value in USD for a shipment with a transaction value of 12000, adding 850 for air freight and 120 for cargo insurance. The source is our freight invoice at https://freightco.example.com/inv-9921 published 2025-01-15 titled 'Freight Invoice 9921'.”
Royalty and commission adjustments
“Can you work out the customs value in GBP for goods with a declared transaction value of 80000, adding 6000 for royalties payable as a condition of sale and 2000 for buying commissions? Source document is https://trade.example.com/royalty-agreement published 2024-12-10 titled 'Royalty Agreement Ref RA-445'.”
Deducting post-import costs from declared value
“Help me figure out the customs value in CHF for a shipment declared at 30000, but I need to deduct 1500 for domestic transport after arrival and 400 for import duties already included in the price. Source is https://supplier.example.com/proforma-2025 published 2025-02-20 titled 'Proforma Invoice PI-2025-003'.”
Technical details
Endpoint
POSThttps://zoll.halowerk.com/v1/customs-value?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a structured, method-disclosed computation of customs value under the transaction-value method, with explicit traceability of each addition and deduction and disclosure of any facts that could not be resolved. Prefer it over manual calculation or generic math tools when you need audit-ready attribution of sources and derivation methods for trade compliance workflows.
Side effects
- Missing required source fields (url, published_at, title) cause validation errors
- Ambiguous or conflicting additions/deductions may result in null customs value with unavailable_fields populated
- Currency code not matching ISO 4217 format triggers rejection
- Transaction value exceeding maximum allowed (1,000,000,000,000) causes schema validation failure
- Insufficient input data returns null for customs value with explanation of missing facts
