Terms of service

These terms govern your use of TariffFlow. Please read them carefully. By creating an account you accept them. If you do not accept them, do not use the service.

1. Who we are and who you are

TariffFlow("we", "us") is operated by Daniel Hamilton, based in Earl Shilton, Leicestershire, United Kingdom. If we later incorporate as a UK limited company we will update this clause with the company number and registered address.

You are the individual or the business entity named on the account. If you sign up on behalf of a business, you warrant that you have authority to bind that business to these terms.

2. The service

TariffFlow is an AI-assisted UK commodity classification tool. You submit product information (text, datasheets, images); we return a recommended UK commodity code, a confidence score, alternatives considered, reasoning citing the General Rules of Interpretation, and a live HMRC duty + VAT lookup.

We maintain a classification corpus sourced from the UK HMRC Integrated Online Tariff and refresh it daily. Live duty and VAT figures are fetched at request time from the HMRC Trade Tariff API and cached for up to 24 hours.

3. Your account

• You must be at least 18 years old and have capacity to enter a binding contract.
• You are responsible for keeping your login credentials secure and for all activity under your account.
• You must provide accurate information. If your circumstances change (role, company name, email), update them in Settings.
• You may delete your account at any time via Settings → Your data. Deletion is permanent; see Privacy for retention details.

4. Subscriptions and billing

• Free tier: 5 Quick Check classifications per calendar month, no card required.
• Paid tiers (Starter, Operator, Enterprise): charged monthly or annually in advance via Stripe. Prices are shown in GBP inclusive of UK VAT where applicable.
• Overage: Starter and Operator include a metered overage rate published on the Pricing page, capped per month so you cannot receive an unexpected bill. When the cap is reached further classifications block until the next billing period or an upgrade.
• Changes of plan take effect at the next billing period for downgrades and immediately (prorated) for upgrades.
• Refunds: we do not offer refunds for time already elapsed. If the service has been substantially unavailable we will consider service credits on request. Statutory consumer rights are not affected.
• Cancellation: cancel any time via Stripe Customer Portal. You keep the features you paid for until the end of your current billing period.

5. Acceptable use

You must not use TariffFlow to:

• Classify goods that are illegal to import or export under UK law.
• Evade customs duty, VAT, or import licensing requirements. The AI-recommended code is your starting point, not your submission to HMRC.
• Classify goods subject to UK sanctions regimes, export controls (ECJU), or goods governed by the UK Firearms Act, Medicines Act, or similar without independent compliance review.
• Attempt to reverse-engineer, scrape at scale, or train competing AI models on the service output.
• Upload content you do not have rights to, including third-party proprietary datasheets where disclosure is restricted.
• Interfere with the service — rate-limit abuse, DoS, or credential stuffing.

We may suspend accounts that breach this clause with written notice where practicable, or immediately where there is an active security or legal risk.

6. Intellectual property

• Your content. You retain ownership of everything you submit. You grant us a worldwide, non-exclusive licence to process it solely to deliver the service. We do not sell your content, do not use it for advertising, and do not train AI models on it.
• Our output. Classifications, reasoning, Case Packs, and other generated output are provided to you to use for your customs workflow. You own the output of your own classifications. We retain ownership of the platform, prompts, rule library, and aggregate analytics.
• HMRC source data. Commodity codes, descriptions, duty rates, and notes originate from the UK HMRC Integrated Online Tariff and are Crown Copyright.

7. AI-assisted output — not a binding classification

TariffFlow produces AI-assisted recommendations. It is NOT a binding tariff ruling, legal advice, or a customs declaration. The correct commodity code for your goods remains your responsibility under UK customs law. You should verify every recommendation before submitting to HMRC, particularly where:

• The confidence score is below 85%.
• The recommendation carries a risk flag.
• The classification sits near a chapter or heading boundary the reasoning explicitly discusses.
• The goods are high-value, subject to preference claims, or under an anti-dumping regime.

For formal clarity you can request a Binding Tariff Information (BTI) ruling from HMRC. TariffFlow is not a substitute for BTI, nor is it customs broker advice.

8. Availability

We aim for high availability but do not warrant uninterrupted service. Planned maintenance is published where reasonably practicable. Unplanned outages are communicated via status page and email to account owners. Enterprise customers may receive a contractual SLA with service credits — see the Pricing page.

9. Privacy and data protection

Our handling of your personal data is governed by our Privacy Policy, incorporated by reference into these terms. For business customers we offer a Data Processing Agreement (DPA) on request.

10. Limitation of liability

Nothing in these terms excludes or limits liability that cannot be excluded or limited under UK law — in particular, liability for death or personal injury caused by negligence, fraud, or fraudulent misrepresentation.

Subject to the above, to the maximum extent permitted by law:

• We exclude all implied warranties, including fitness for a particular purpose and satisfactory quality, to the fullest extent permitted.
• We are not liable for indirect, consequential, or special losses; loss of profits, revenue, customs duty liability, fines, goodwill, or data; or losses arising from reliance on any AI-generated output.
• Our total aggregate liability to you under or in connection with these terms in any twelve-month period is capped at the greater of (i) the fees you paid us in that period, or (ii) £100.

This allocation of risk reflects the price you pay for the service. You should maintain your own customs compliance review and professional indemnity where appropriate.

11. Indemnity

You will indemnify us against claims, damages, and costs arising from (a) your breach of these terms, (b) your misuse of the service, or (c) content you upload that infringes third-party rights.

12. Termination

• Either party may terminate for convenience at any time by cancelling the subscription or deleting the account. You remain liable for fees already accrued.
• We may terminate immediately for breach of these terms, fraud, non-payment, or legal requirement.
• On termination, we deactivate your access. Account deletion purges data per the retention schedule in the Privacy Policy.

13. Changes to these terms

We update these terms occasionally — new features, pricing, legal requirements. Material changes are announced by email to your registered address at least 14 days before taking effect. Continued use after the effective date constitutes acceptance.

14. Governing law

These terms are governed by the laws of England and Wales. The courts of England and Wales have exclusive jurisdiction over any dispute, except that we may bring proceedings against you for unpaid fees in any court of competent jurisdiction.

15. General

• These terms are the entire agreement between you and us for the service. They supersede any prior agreement or representation.
• If any clause is held unenforceable, the remainder continues in full force.
• Failure to enforce a clause is not a waiver of our right to do so later.
• You may not assign your rights under these terms without our written consent. We may assign freely in connection with a sale of the business or restructure.
• Third parties (Contracts (Rights of Third Parties) Act 1999) have no rights under these terms.
