Customs duty depends first on the tariff classification of the goods, then on their origin and value. Classification uses the internationally harmonised commodity code, extended by each market, and an error flows through to duty, licensing and preference claims. Binding rulings in the EU, UK, US and India give advance certainty and are worth obtaining for high-volume or borderline products.
Headline duty rates differ widely
The GCC states apply a common external tariff. Dubai Customs states a standard rate of 5% of the CIF value, with 50% on alcohol and 100% on tobacco, and Saudi Arabia applies at least 5% to most goods from outside the GCC. India's basic customs duty is generally levied at 7.5% or 10%, with other levies on top. The UK applies the UK Global Tariff unless an exception such as a trade agreement applies.
United States tariffs have changed sharply. On 20 February 2026 the Supreme Court held that the International Emergency Economic Powers Act does not authorise the President to impose tariffs, although duties under other statutes, such as Section 232 and Section 301, are unaffected. Any landed-cost model for the United States should be dated and checked against the current tariff schedule.12345
Binding rulings give certainty before shipping
A binding tariff information decision in the EU is free, valid for three years and binds customs in every member state. Great Britain issues Advance Tariff Rulings, which are legally binding for Great Britain only; HMRC aims to reply in 30 to 120 days and will not rule on goods already cleared. HMRC also issues Advance Origin Rulings, valid for three years.
In the United States any importer, exporter or other interested person may request a written ruling, generally for prospective transactions; oral advice from CBP staff is not binding. India's Customs Authority for Advance Rulings can rule on classification, valuation, exemptions and origin, with rulings binding for three years; a 2026 proposal to extend this to five years should be checked.67891011

Decisions to make
- Is the classification of the main products settled, or could it fall under two headings?6710Classification drives the duty rate and whether a product falls inside a preference or licensing rule; a binding ruling removes the doubt.
- Do we need a ruling before the first shipment?78HMRC will not issue a retrospective Advance Tariff Ruling and may take up to 120 days to reply.
- Which US duties apply to the product today, and under which statute?5IEEPA-based tariffs were held unlawful in February 2026, but Section 232 and 301 duties remain.
- Will the ruling cover origin as well as classification?911Origin decides whether a preferential rate can be claimed; the UK and India both offer binding origin rulings.
Documents usually needed
- Product technical specifications, composition and function descriptions
- Photographs, data sheets and samples for ruling applications
- Existing binding rulings and their expiry dates
- Tariff schedule extracts used for each market, with the date checked
- Internal classification decisions with reasoning
Common mistakes
- Copying the exporter's commodity code into every import market without checking national extensions
- Assuming a ruling in one market binds another; an EU ruling does not bind Great Britain
- Relying on oral advice from customs staff
- Pricing US contracts on tariff rates that have since changed
- Forgetting that surcharges and import VAT sit on top of the headline duty rate

An Advance Tariff Ruling from HMRC is a legally binding decision on the commodity code to use when importing goods into or exporting goods from Great Britain. Great Britain only; for Northern Ireland or the EU a Binding Tariff Information decision is needed instead. It must be applied for before all customs procedures are completed; retrospective decisions are not possible.
HMRC states that it will reply to an Advance Tariff Ruling application in 30 to 120 days. Great Britain. The page does not state a fee or a fixed validity period.
An HMRC Advance Origin Ruling on the origin of goods imported into or exported from Great Britain is legally binding in the UK and valid for 3 years from the date of issue. Applicants need an EORI number starting GB. Protection applies while production arrangements relevant to the origin rules remain unchanged.
