Send a product description, get back the HS code, the declarable national line, a confidence score and the legal reasoning, in about 12 seconds. Your experts stop looking up codes and start checking only the lines that need them.
Manual classification is minutes per product for a trained person and a queue for everyone else. Nomenclo does the lookup, the reasoning and the national line, and tells you which answers deserve a human look.
A 2,000-line monthly entry file is days of lookup work. Sent in batches of ten, it comes back classified within the afternoon, each line with its 10-digit code and reasoning.
Every answer cites the heading text, the section and chapter notes and the GRI applied. When data is missing, the line says what to ask the shipper instead of guessing.
Your licensed people review the 10 to 15 % of lines flagged needs_review instead of typing the other 85 %. Same team, more entries, more clients billed.
Six situations our users face daily. Left: how it goes today. Right: the same job with one API call.
Today
Thousands of merchant item descriptions in a dozen languages, a 10-digit HTSUS line required for each since July 2026, one spreadsheet due by the 7th. The team looks codes up by hand and the file is always late.
With Nomenclo
Your system sends each description with destination_country: "US"; the answer carries the HS6, the HTSUS 10-digit line chosen among the official USITC lines, the confidence and the reasoning you keep for the audit trail. Batches of 10 per call, sent in parallel.
Result: the monthly file is ready in hours, not days; your broker reviews only the flagged lines; you take on more consolidators with the same staff.
Today
EUR 3 of duty per declaration line, a CN8 or TARIC10 line to provide, and parcels blocked when the line is wrong or missing. Chinese, German or Spanish product titles land in the queue as they are.
With Nomenclo
Send the title in its original language with the member state as destination; get the CN8 and TARIC10 line, the confidence and the alternative rejected. Lines under 0.80 confidence are re-read by a larger model before they reach you, and still flagged.
Result: fewer blocked parcels and duty disputes, one line per product, a defensible answer when customs asks why.
Today
Without an HS code you cannot quote duties, so you ship DAP and the customer discovers the bill at delivery: refused parcels, returns, chargebacks, one-star reviews.
With Nomenclo
Classify each product once when it is created (title plus description, any language), store the HS6 and national line, and feed your duty calculator. The free lookup endpoints verify a code or list its national lines at no cost.
Result: DDP pricing you can show before payment, fewer refused deliveries, catalogues classified overnight for $0.10 a product or less.
Today
A prospect sends 5,000 SKUs on Friday and wants a quote and a clearance set-up on Monday. Classification is the bottleneck, and the junior who does it has no way to show how a code was chosen.
With Nomenclo
Run the catalogue through the batch endpoint over the weekend. Each line comes back with code, national line, confidence, GRI reasoning and alternatives: the review sheet writes itself.
Result: quote on Monday, onboarding in days, and an audit trail your compliance team signs off.
Today
Sellers leave the HS field empty or copy a wrong code from a competitor's listing; cross-border orders fail at the carrier label step.
With Nomenclo
Suggest the code at listing time from the seller's own title and description, show the official wording and the confidence, let the seller confirm. Re-check the catalogue monthly with the lookup endpoints when tariffs change.
Result: complete, consistent HS data across the catalogue, fewer failed labels, more sellers shipping abroad.
Today
Years of codes assigned by different people and never revisited. A post-clearance audit means re-checking thousands of lines by hand, with the penalties on the lines you miss.
With Nomenclo
Send your descriptions with your current codes alongside. The agreement rate shows where to look first; every disagreement comes with the reasoning and the alternative, so your expert decides in seconds instead of researching from scratch.
Result: a prioritised review list in an afternoon, documented decisions, lower exposure.

A 78-second illustrative conversation between a customs-ops lead and a compliance manager: what changed when the monthly HTS file stopped being a manual job. Fictional names, no real customer shown.
Three steps, one JSON answer. The AI never writes a code from memory: it picks among the official texts and explains the pick.
The description is read in its language; the model proposes candidate headings and search terms.
Candidate headings are expanded to every official subheading text plus the section and chapter notes; the model applies GRI 1 to 6 and explains.
For a US, UK or EU destination the declarable line is chosen among the official tariff lines. Doubtful answers get a second opinion from a larger model.

Nomenclo is classification assistance, not a binding ruling. The declarant remains responsible for the classification declared; confirm high-value, regulated or disputed goods with a licensed customs broker or a binding tariff information request. WCO Explanatory Notes are not reproduced.
On the public benchmark of 40 products in five languages, the production configuration returned the correct six-digit subheading 40 times out of 40, median 12 seconds. Every answer and the benchmark are on the benchmark page. A benchmark is not a guarantee: the confidence score and the needs_review flag tell you where a human should look.
Yes, chosen among the official USITC lines under the subheading, with its description. For the EU: CN8 and TARIC10. For the UK: the 10-digit commodity code.
Most tools return a code. Nomenclo returns the code, the reasoning under the General Rules of Interpretation, the notes applied and the alternatives rejected, which is what an audit asks for. Run it as a second opinion: send your current codes alongside and the agreement rate tells you where to look.
Product descriptions in any language. Answers in English, with the official nomenclature wording.
Product descriptions are used only to produce the answer and are not retained by Nomenclo. Do not send personal data. Requests are processed by a third-party AI provider under its commercial API terms.
HS 2022 stays in force until HS 2028. National lines change each January; the dataset is rebuilt from the official publications and the data version is returned with every answer.
