1. PROHIBITION OF THIRD-PARTY PROXIES
POAs CANNOT be set up through unlicensed intermediaries or third-party agents without direct IOR validation. The IOR must execute the POA directly with the customs broker.
2. MANDATORY IMPORTER IDENTITY VERIFICATION
Customs brokers MUST verify the identity of the grantor prior to transacting customs business (19 CFR § 111.24 / § 111.38). Requires checking unexpired photo IDs, state business registry, EIN/IRS documentation, and credit/business databases.
3. 24/7 POINT OF CONTACT (POC) REQUIREMENT
Customs brokers must designate a 24/7 POC available to CBP for immediate commercial incident response.
CBP Form 5106 integration & importer identity verification
CBP Form 5106 Integration & Importer Identity Verification

IRS Employer Identification Number (EIN) or Social Security (SSN). CBP-Assigned Number (for foreign non-resident importers).
2. CORPORATE & OFFICER INFORMATION

The table below demonstrates real-world landed financial impacts for an importer purchasing 1,000 units of industrial machinery ($20.00/unit base factory price; total $20,000 base value) shipped from Shenzhen, China to a commercial warehouse in Los Angeles, California:
| Cost & Compliance Element | Option A: Unverified Indirect Proxy POA (CBP Hold Risk) | Option B: SIS Verified Direct 19 CFR 111 POA + Fast Sea DDP |
|---|---|---|
| Base Factory Product Cost (1,000 units) | $20,000.00 | $20,000.00 |
| Main Carriage Freight & Duties (10.9% Duty) | $4,500.00 | $4,800.00 (All-inclusive DDP rate) |
| SIS Direct POA Setup & CBP 5106 Identity Verification | $0.00 (Proxy attempted) | $150.00 (100% compliant direct verification) |
| CBP Customs Detention & Storage Hold (10 Days @ $350/day) | $3,500.00 (Invalid POA / Form 5106 hold) | $0.00 (ACE entry pre-cleared at sea) |
| Customs Attorney Re-Filing & Legal Penalty Fee | $1,200.00 (Emergency re-filing fee) | $0.00 (Zero compliance errors) |
| ACE Customs Re-Entry Administrative Fee | $250.00 | $0.00 (Included in DDP) |
| Total Realized Project Outlay | $29,450.00 | $24,950.00 |
