Importing an ASIC Miner from Canada to the US: Duty, Customs & De Minimis

Quick answer

Plan on paying US import duty and a customs/brokerage entry — the old $800 “de minimis” duty-free threshold no longer applies (it was eliminated for China/Hong Kong on May 2, 2025 and for all countries on August 29, 2025), so a low declared value will not get a miner in duty-free anymore. The exact rate depends on the tariff classification (mining ASICs are generally argued under HTS heading 8543, though some rulings place computing equipment under 8471) and on whether it qualifies for USMCA — which a China-made rig shipped from Canada usually does not. Because 2025 US tariff rates are moving fast, get a quote from a licensed customs broker for your shipment rather than trusting a number off a web page. As-of 2026-07-21.

Reference, not customs advice. Cross-border duty is fact-specific and, in 2025, unusually volatile. This page gives the durable framework and points you to the primary sources; it does not quote a rate for your shipment. For that, use a licensed customs broker.

1. The $800 de minimis is gone — this is the big change

For years, a shipment under US$800 could enter the US duty-free under the Section 321 “de minimis” rule. That door has closed: the exemption was suspended for China and Hong Kong on May 2, 2025, and then for all other countries (including Canada) effective August 29, 2025. Practically, you can no longer count on a low declared value to avoid duty and a formal-entry process on a miner.

2. Classification decides the rate — and it’s contested

US duty is driven by the item’s HTS (Harmonized Tariff Schedule) code. Bitcoin mining ASICs are most often argued under heading 8543 (electrical machines/apparatus with individual functions), but there are CBP rulings and arguments that place data-processing-type equipment under 8471. The two can carry different treatment, and on top of the base rate there may be Section 301 (China-origin) tariffs and other 2025 trade-action duties. This is exactly why a number off a blog is unreliable — confirm the classification for your unit.

3. USMCA usually will not save a China-made rig

Because D-Central ships from Canada, buyers sometimes assume USMCA (the Canada-US-Mexico agreement) makes it duty-free. USMCA preference turns on rules of origin, not the country you ship from. A miner manufactured in China and merely re-exported through Canada generally does not meet USMCA origin, so USMCA preference typically does not apply. A unit genuinely built or substantially transformed in Canada is a different case — but do not assume it.

4. What actually lands on you

Duty at the applicable HTS rate (+ any Section 301 / 2025 trade-action tariffs).
A customs entry, and usually a customs broker fee to file it, plus the Merchandise Processing Fee on formal entries.
The carrier’s brokerage/disbursement charges if you let them handle clearance.

Under our shipping policy, import duties and taxes on cross-border orders are the buyer’s responsibility — this page is here so that is never a surprise at your door.
