How this service works
US CBP Section 321 ($800 de minimis) eligibility & 2025/2026 China/Section 301 exclusion evaluator. Pass ?shipment_value_usd=180&origin=CN&subject_to_301=true. Returns Section 321 eligibility, recommended CBP Entry Type (Type 86 vs Type 11 Informal vs Type 01 Formal), anti-structuring rules, and bond/MPF checklist. Educational reference only; not legal advice.
Output
Returns a JSON object indicating whether the shipment is Section 321 eligible (boolean), the recommended CBP entry type (e.g. Type 86, Type 11 Informal, Type 01 Formal), an array of 2025/2026 enforcement notes relevant to China and Section 301 exclusions, a fallback entry checklist covering bond and MPF requirements, and a legal disclaimer noting educational use only.
Example use cases
Small e-commerce import eligibility check
“I'm importing a $350 product from China that's classified under an HTS code subject to Section 301 tariffs — does it still qualify for Section 321 de minimis in 2025, and what CBP entry type should I file?”
Vietnam low-value shipment entry type
“I have a shipment worth $600 coming from Vietnam that is not subject to Section 301 tariffs — can you check if it qualifies for de minimis and whether I should use Type 86 or Type 11?”
Anti-structuring compliance for multiple parcels
“We're splitting a $1,200 order into two $600 shipments from China, both subject to Section 301 — does each qualify for Section 321, and are there any anti-structuring rules I need to worry about?”

Endpoint
GEThttps://x402-niche-briefs.fly.dev/v1/de-minimis-321-eligibility?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic evaluation of Section 321 de minimis eligibility and CBP entry type selection for a specific shipment, especially when dealing with Chinese-origin goods potentially subject to Section 301 tariffs. Prefer this over general tariff lookup tools when you specifically need the Type 86 vs informal vs formal entry decision tree and anti-structuring guidance for 2025/2026 enforcement rules.
Side effects
- Missing required query parameters (shipment_value_usd, origin, subject_to_301) returns a validation error
- Invalid ISO country code may produce unexpected results or an error
- subject_to_301 must be the string 'true' or 'false', not a boolean — type mismatch may cause failure
- Regulatory data reflects a specific as_of date and may not reflect real-time CBP rule changes
- Payment of $0.01 USDC required per call; insufficient funds returns 402 Payment Required
