How this service works
US de minimis (Section 321) check: the $800 per person per day limit (plus $100 gift and $200 traveller limits), whether duty-free de minimis is currently suspended according to the newest Federal Register documents, and whether a shipment value can enter duty-free today. Lists the latest CBP rules and presidential documents on de minimis with dates, numbers and links.
Output
Returns a JSON object containing: whether de minimis is currently suspended (boolean), the basis for the suspension status (title, date, document number, Federal Register URL), the current monetary limits ($800 per-person-per-day, $100 gift, $200 traveller), whether a supplied shipment value is under the limit and qualifies for duty-free entry, the governing statute (19 U.S.C. 1321(a)(2)), a list of the latest CBP rule/notice documents with titles, dates, and URLs, a list of the latest presidential documents on de minimis, and a timestamp of when the check was performed.
Example use cases
E-commerce shipment duty-free eligibility check
“I'm shipping a $350 package to a US customer — can you check if the Section 321 de minimis exemption is still in effect and whether that shipment value qualifies for duty-free entry right now?”
Trade compliance policy monitoring
“Pull the latest Federal Register and CBP documents on US de minimis suspension so I can see if there are any new rules or presidential orders affecting our import operations.”
Cross-border logistics decision support
“We're deciding whether to consolidate or split a shipment worth $950 into the US — what are the current de minimis limits per person per day, and is the $800 duty-free threshold currently active or suspended?”
Technical details
Endpoint
GEThttps://api.tradeenergy-api.workers.dev/api/logistics/us-de-minimis-section321?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a real-time, authoritative check on US Section 321 de minimis status grounded in the latest Federal Register and CBP documents — especially when the regulatory environment is volatile (active suspension orders). Prefer over manual research or static databases when you need both the current threshold values and the specific legal document citations backing the status determination.
Side effects
- Federal Register API unreachable — may return stale or cached suspension status
- Invalid or non-numeric valueUsd query parameter — may cause parsing error or ignored parameter
- Suspension status may lag real-world effective date if Federal Register documents are published after effective date
- Truncated presidential/CBP document lists if many documents match the query
