The right code,
argued for.
Droblet Tariff suggests commodity codes as ranked candidates with the words each one matched, looks up the duty, VAT and measures a code carries, models landed cost across a consignment, and screens parties against sanctions lists. It informs the declarant's choice; it does not make it for them.

Why candidates and not an answer
The commodity code on a declaration is the importer's legal liability. A tool that returns one code with a confidence percentage invites the declarant to accept it, and makes the reasoning invisible when customs later disagrees.
Droblet Tariff returns a short ranked list instead, and for each candidate shows the words in the product description that matched it. A declarant can see at a glance why "lithium battery pack" landed on 8507 60 and not 8506, and can overrule it with a reason that is kept. The decision stays with the person; the evidence is laid out for them.
The same principle runs through the rest of the product. An unknown duty rate is reported as unknown, never as zero. A prohibition is its own flag, not a footnote. A sanctions screen that finds nothing tells you how many names it checked, so an empty list on an empty register does not read as "clear".
What it does
Classification
Candidate commodity codes ranked by match, each with the matched terms and a note on what would distinguish it from its neighbours.
Duty lookup
Third-country duty, preferential rates where an origin is given, VAT rate, licences and prohibitions for a code. Unknown is unknown, not zero.
Landed cost
Duty on the customs value including freight and insurance, VAT on the duty-inclusive value, line by line and for the consignment.
Sanctions screening
Party names and identifiers screened with legal-form stripping and tolerant matching. Over-reports rather than under-reports; shows how big the list screened was.
Reference data kept current
Commodity codes, duty rates, measures and sanctions lists refreshed nightly from the sources you configure, with a guard that refuses an update that would empty a table.
Everywhere you work
In the Droblet app, on the REST API, and as the classify_commodity, lookup_duty, model_landed_cost and screen_party MCP tools.
The free tools on this site (HS code search, import duty and landed-cost calculators) run on the public UK Trade Tariff. Droblet Tariff inside the platform adds ranked candidates with matched terms, your own master data, screening, and a record of every decision.
Common questions
It suggests. The candidates and their matched words are shown to the declarant, who picks one. That choice and any override are recorded against the declaration.
Whatever you load: UK Trade Tariff, EU TARIC, or both. Reference data is loaded through the admin endpoints and refreshed nightly.
The lists you configure, typically UK OFSI, EU consolidated and US OFAC SDN. The screen reports how many entries it checked so an empty result is meaningful.
