Prepare a source-checked United Kingdom to USA import duty estimate using product facts, manufacturing origin, customs value, a verified US HTS rate, additional measures, and separately labeled fees.
A United Kingdom seller or ship-from address does not by itself determine origin or duty; use production facts and the US origin rules that fit the product.
US import duty begins with the product-specific HTS line and customs value, not a universal country percentage.
Additional duties, trade remedies, user fees, excise taxes, and carrier charges are separate layers and should be labeled and verified independently.
Use a candidate HS code, verify duty rate, verify additional tariffs, verify tax/VAT/GST where applicable, and keep a source-check required note. The result is estimate-only and not a filing result.
| Input | How to prepare it |
|---|---|
| Detailed product facts | Record material, function, construction, model, and use. The worked example uses wool-blend apparel fulfilled from a UK warehouse, but every SKU needs its own facts. |
| Manufacturing country of origin | Confirm where the product was made or substantially transformed. Do not use United Kingdom merely because it was sold or shipped from there. |
| US HTS candidate | Prepare a candidate from the product facts, then verify the complete US HTS line, notes, and unit of quantity in the current USITC schedule. |
| Customs value basis | Start from the transaction records and add only the amounts required by the applicable valuation method. Keep freight, assists, packing, commissions, and related-party questions visible. |
| Base duty rate | Enter the rate shown for the verified HTS line and treatment column that applies to the shipment facts. |
| Additional measures | Check separately for additional tariffs, trade remedies, quotas, excise taxes, and other product-specific measures. Do not infer them from country alone. |
| Entry and transport fees | Review MPF by entry type and HMF for applicable vessel cargo. Brokerage and carrier disbursement fees are not the same as customs duty. |
| Source date and evidence | Save the HTS revision or access date, origin evidence, invoice, fee source, and assumptions used in the estimate. |
Estimated border cost = base duty + verified additional duties or taxes + applicable MPF/HMF + separately identified brokerage or carrier fees. Base duty = customs value x verified HTS duty rate. Do not replace this product-specific stack with a country headline rate.
Use the connected calculator as a preparation aid. Enter only source-checked rates and keep the official source note with the estimate.
Scenario: A US ecommerce importer buys wool-blend apparel fulfilled from a UK warehouse from a supplier in United Kingdom. The importer has an invoice, product specification, origin evidence, transport mode, and a working HTS candidate but has not yet verified the final rate.
Treat the United Kingdom as the origin only when manufacturing or substantial-transformation evidence supports it; a UK seller, invoice, or warehouse is not enough. Check the current US HTS and USTR implementation sources for product-specific UK treatment or arrangements in force on the entry date; do not assume a comprehensive US-UK free-trade rate. For apparel, footwear, food, alcohol, machinery, and automotive goods, keep product-specific duty, excise, agency, and additional-measure checks separate.
Written by the TariffCatalog Editorial Team for route-specific duty, landed cost, and DDP estimate preparation. The page uses the connected Import Duty or Landed Cost calculator within its coverage boundary, and source-check required review for rates outside that boundary.
Maintained by Ryan Cole, with review focused on ecommerce route assumptions, catalog inputs, and estimate-only calculation boundaries.
Within the coverage boundary, TariffCatalog auto-resolves duty rate, Section 301 additional tariff, MPF, and HMF from official tariff sources and the TariffResolver. Outside the coverage boundary or for complex scenarios, the page returns editable fields and prompts source-check required review. Each estimate is always marked estimate-only and not a filing result.
Use official sources for final classification, duty rate, additional tariff treatment, tax/VAT/GST where applicable, and document requirements. Route pages are estimate-only and not a filing result.

There is no universal United Kingdom rate for every product. The applicable amount depends on the verified US HTS line, customs value, manufacturing origin, treatment column, entry date, and any additional product-specific measure.
No. A seller, warehouse, port, or ship-from address in United Kingdom does not by itself prove origin. Review where the goods were manufactured or substantially transformed and retain supporting records.
Base duty is generally estimated as customs value multiplied by the verified ad valorem HTS rate. Specific or compound rates need the units and formula shown in the tariff schedule.
They are separate customs user fees. MPF depends on entry type and HMF may apply to commercial vessel cargo at covered ports. Keep them separate from the tariff rate.
Yes. Additional tariffs, trade remedies, excise taxes, quotas, or other measures may apply to particular products and origins. Verify them separately rather than using a country-wide assumption.
Prepare a candidate from material, function, construction, and use, then verify the complete US HTS line and notes in the current USITC schedule.
No. Brokerage, advancement, disbursement, and clearance charges are carrier or broker fees. They can affect landed cost but should not be labeled as customs duty.
No. It is an estimate-only preparation workflow. CBP treatment depends on the entry facts, records, and official review.
TariffCatalog route pages provide estimate-only calculation support, candidate HS code workflows, and source-check required notes. They are not a filing result and do not replace official tariff databases, carrier requirements, or destination authority review.
