Duties and tariffs on materials in plain language: who pays, what to ask, what to keep
The extrusion quote says 'subject to applicable tariffs'. The purchaser does not know whether the price includes customs charges, which import arrangement applies or what would change at invoicing. A broad label could conceal several different questions.

Ask what the tariff wording actually includes, who handles the import and how the supplier proposes to adjust the price. Obtain current customs and contractual review before relying on it. Customs liability and the parties' purchase-price allocation are separate questions. This lesson gives vocabulary and a purchasing record; it does not identify an applicable rate, calculate liability or interpret your contract.
A tariff is an import duty; headlines may use that word for a surtax. Customs duty is a government charge on certain imports. A surtax is an additional government charge under a specific measure. Anti-dumping duty is a separate trade-remedy duty under the Special Import Measures Act, addressing the comparison of normal value and export price. A supplier's 'surcharge' needs explanation rather than being assumed to name any one of these.
Resolve four purchasing questions
- Ask about the goods and origin. Obtain the exact product description and country-of-origin information the customs professional needs. Classification, origin and applicable treatment affect customs assessment. Do not select a rate from a headline or assume a shipping address establishes the answer for a specific product.
- Ask what the quoted price includes. Have the supplier identify included customs charges, separate fees and exclusions, and distinguish a government assessment from its own price adjustment. Identify the importer of record with the responsible advisers. Customs law can involve liability of several parties; that label alone does not settle every obligation or who bears cost under your purchase.
- Ask how long the price is held. Record the validity date, relevant shipment assumptions and proposed treatment of later changes. Obtain clear evidence and review of any pass-through wording. Do not assume an earlier quotation freezes a government assessment or that a stated expiry grants an unlimited later increase.
- Ask what can move the price. Request the actual trigger, calculation basis, evidence and approval process proposed for adjustments. Send customs questions to a qualified customs professional and contract questions to the authorized legal or purchasing advisers. Record the reviewed agreement before issue, keeping unresolved conditions visible.
Keep product information, quote revisions, the authorized order, supplier responses and relevant customs evidence together through the approved record process. Have the responsible advisers identify required retention and confidentiality arrangements. Compare an invoice adjustment with the actual reviewed basis; do not accept it solely because its line says 'tariff', or refuse a customs issue because a supplier once quoted a base price.
Common mistakes
- Applying a news headline's rate to an unidentified product.
- Treating importer-of-record status as the whole cost-allocation answer.
- Paying an unexplained surcharge solely because it is labelled tariff.
Checklist
Clarify an imported-material quote
- Exact product and origin information.
- Included charges, exclusions and import arrangement.
- Price validity and shipment assumptions.
- Reviewed adjustment trigger, basis and evidence.
- Authorized order and relevant customs records.
Check your understanding
The supplier is importer of record. Does that prove the quoted price includes every duty change?
