The deliverable
A structured PDF for practical UK customs review. Recommended code, GRI walk, relevant published ruling examples, current HMRC measures, risk flags, and an integrity record. Included on every plan.
Signed example PDF · includes published HMRC Advance Tariff Ruling IDs
Signed example: USB webcam 1080p → 8525 89 00 00. Three published HMRC Advance Tariff Ruling examples cited (ATaR 600012163, 600014467, 600014782).
What's in every pack
The structure is fixed so your compliance team can scan any pack the same way. No bespoke templates, no guessing where the reasoning went this time.
10-digit UK commodity code rendered prominently with a qualitative evidence-strength label (High / Medium / Low), paired with the GRI rule applied and a four-column trust summary strip.
Section → chapter → heading → leaf, with the pick at each level, the GRI rule applied, recorded reasoning, and alternatives considered. It gives your team or broker a readable decision trail to review.
When the pick aligns with published HMRC Advance Tariff Rulings, each is cited by ID with its goods description and expiry date. Decisions are non-transferable, so the pack links to HMRC for you or your broker to compare the exact goods and legal reasoning.
The pack records the available tariff and retrieval evidence behind the result, which may include UK tariff data, HMRC search references, published UK ruling examples, EU BTI examples, legal notes, and the GRI applied.
Severity-tinted callouts for anything worth a human double-check before filing: borderline GRI calls, accessory-set ambiguity, antidumping exposure, verification failures. High-severity flags appear in amber; medium in muted; low in grey.
The available MFN duty, UK VAT, supplementary unit, origin-dependent preferences, documentation codes, and trade-defence measures are fetched from HMRC's current Trade Tariff service for the selected code.
Each issued PDF is digitally signed as a TariffFlow artifact and recorded with a SHA-256 file hash. The verification page compares an uploaded PDF with the issuance record; this is not a qualified electronic signature or proof of professional approval.
End-to-end workflow
TariffFlow is a classification tool on the surface and a compliance-records system underneath. Every case is retained until you delete it, so you can reuse the facts and revisit the evidence instead of relying on a transient chat answer.
Paste a product description, upload a datasheet, or add a photo. The classifier combines tariff retrieval, evidence cards, model review, and deterministic checks.
Every plan can issue an artifact-signed Case Pack PDF at the end of the flow, with a consistent structure and the evidence available for that case.
The case (and its pack) are saved to your library with a stable URL. Full export or delete any time.
Import the same product again — whenever specs change, or for the next shipment — from the saved fact sheet, not from scratch.
If HMRC or your broker queries the classification, you hand over the pack. Reasoning, precedent, verification hash — all in one document.
Why it matters
Every issued pack is recorded with a SHA-256 file hash and a verification URL. The PDF keeps reasoning, GRI citations, relevant ruling examples, and the artifact record together.
Send your customs broker or freight forwarder a read-only share link. They see the recommendation, cited examples, and reasoning walk without needing a TariffFlow account.
Save the product once, reclassify whenever specs change. The library holds the structured facts so you're not copy-pasting the datasheet every time a new purchase order lands.
Start with five complete classifications per billing period. Every plan includes the full workflow, Case Pack, sharing, and library.
