For years, the practical rule of small imports into the US was simple: shipments valued at $800 or less entered duty-free under the de minimis exemption, with minimal paperwork. That rule no longer exists.
Effective 29 August 2025, de minimis treatment was suspended for all countries — imports from China and Hong Kong had already lost it that May. Now every shipment, regardless of value, is subject to applicable duties, taxes, and entry requirements. For postal shipments there was a transition: a flat per-package duty ($80–$200) could be used instead of percentage-based duty, but from 28 February 2026 only the ad valorem (percentage) method applies.
The practical effect: the $40 gadget that used to arrive with no paperwork now generates a duty calculation and a receipt — and consumers are seeing customs charges for the first time on purchases that never used to carry them.
Import duty is not one rate — it is a lookup. Three inputs decide the figure:
The HTS classification — every product maps to a code in the Harmonized Tariff Schedule, and the code carries the duty rate. Getting the classification right (or wrong) changes the bill.
The customs value — generally the price paid, which is why the commercial invoice accompanies the shipment and why undervaluing it is fraud.
The country of origin — trade agreements, and in recent years additional tariffs, apply by origin. Origin is where the goods were made, not where they were shipped from.
An ad valorem duty is a percentage of that customs value. Your receipt should let you reconstruct the arithmetic: value × rate = duty, plus any additional tariffs, fees, and taxes itemised separately.
Duty is owed by the importer of record — and for a consumer purchase from abroad, that is usually you, not the seller. The seller's price did not include US duty unless the terms said so explicitly (delivered-duty-paid, often shown as DDP at checkout).
This is why the carrier's message asking for payment before delivery is usually legitimate: the carrier or broker advanced or calculated the duty, and the goods will not be released until it is paid. It is also why the paperwork matters — a payment demand should reconcile to a duty calculation you can see, not just a total.
The entry or reference number — the identifier for the customs entry itself.
The customs value declared, and the HTS code(s) applied.
The duty rate and amount, with any additional tariffs shown separately.
Taxes (where applicable) and fees, each named.
The shipment identifier — tracking or waybill number — tying the payment to the goods.
Keep it with the commercial invoice and the order confirmation: together they show what was bought, what was declared, and what was paid — the complete story a dispute or an audit needs.
For a business, import duty is part of the landed cost of goods — it belongs in inventory cost and margins, not lost in a shipping-expenses line. The duty receipts are also the audit trail: customs authorities can and do review entries after the fact, and reclassification or revaluation disputes are argued from exactly these documents.
Duty overpayments can sometimes be recovered — refund claims for overpaid duty run on the entry number and the original receipts. If a record is missing while the payment genuinely happened, the carrier or broker can reissue their invoice and the entry documentation, and your card or bank statement establishes what you paid; a clear reconstructed record documents that real payment for your files, matching it exactly, while the entry paperwork remains the document customs itself recognises.
