Terms of service

These terms govern your use of TariffFlow. TariffFlow is supplied for trade, business and professional use, not personal or household use. By creating an account or purchasing a plan you agree to these terms. If you act for an organisation, you confirm that you can bind it.

1. Who we are and who you are

TariffFlow ("we", "us") is operated by Daniel Hamilton, trading as TariffFlow, with a service address in Earl Shilton, Leicestershire, United Kingdom. Our service contact is support@tariffflow.app. Confirmed company and VAT registration details will be published here if and when they apply.

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 such as text, datasheets and images. The output may include a recommended UK commodity code, a qualitative evidence-strength label, alternatives considered, reasoning under the General Rules of Interpretation, current HMRC measures and a Case Pack. Every plan has the same workflow; plans differ by classification allowance, overage, support, and any separately contracted Enterprise services.

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 complete classifications per billing period, no card required.
• Self-serve paid tiers are charged monthly in advance through Stripe. Enterprise terms are agreed in an order form. Published prices are in GBP and exclude VAT; VAT is added where legally required.
• 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 only to provide, support, secure and improve the service for you. We do not sell your content or include classification content in advertising events.
• Our output. To the extent we hold the relevant rights, we grant you a perpetual, worldwide, non-exclusive licence to use classifications, reasoning and Case Packs generated for your account in your business. This does not transfer rights in the platform, prompts, rule library, third-party material or Crown copyright data.
• 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 evidence strength is Medium or Low.
• 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 apply to HMRC for an Advance Tariff Ruling for goods imported into Great Britain. Different routes, including Binding Tariff Information, apply to Northern Ireland and the EU. TariffFlow is not a substitute for a ruling or customs-broker advice.

8. Availability

We aim for high availability but do not warrant uninterrupted service. We give reasonable notice of planned maintenance where practicable. Any service level or service credit applies only when it is expressly included in an Enterprise order form.

9. Privacy and data protection

Our handling of personal data is described in our Privacy Policy. For personal data that we process solely on your behalf, you are the controller and we are the processor. These terms are the written processing agreement: we process that data only on your documented instructions to provide and secure TariffFlow; keep authorised people subject to confidentiality; use appropriate technical and organisational safeguards; assist reasonably with data-subject requests, security incidents and compliance assessments; require equivalent protections from subprocessors; delete or return the data at the end of the service subject to legal retention; and provide information reasonably needed to demonstrate compliance. You give general authorisation for the service providers listed in the Privacy policy and may object on reasonable data-protection grounds to a material new processor notified in advance.

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 the fees you paid us in that period or £100, to the extent that this limitation is reasonable and enforceable under applicable law.

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 a third-party claim arising directly from content you upload without the necessary rights or from your deliberate unlawful use of the service. We must notify you promptly, allow you reasonable control of the defence and settlement, cooperate at your expense, and take reasonable steps to mitigate the loss. You may not settle a claim in a way that admits liability for us or imposes a non-monetary obligation on us without our consent.

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 a material breach that cannot be remedied, fraud, an active security risk or legal requirement. For a remediable breach, including non-payment, we normally give a reasonable opportunity to put it right first.
• Cancelling a paid plan does not delete your TariffFlow application data; cases and saved products remain until you delete them. Deleting your account requests application-data and private-file deletion, cancels an active subscription, and closes the linked sign-in account, subject to the provider and legal-retention details in the Privacy Policy.

13. Changes to these terms

We update these terms for new features, pricing or legal requirements. We give at least 30 days' notice of a materially adverse change unless law or an urgent security issue requires less. You may cancel before that change takes effect. Changes do not retrospectively alter amounts already paid.

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.
