Verify country of origin, identify transshipment risks, and build an auditable supply chain due diligence record — all from public CBP data.
Trade compliance teams face growing pressure to verify supply chain claims: the Uyghur Forced Labor Prevention Act (UFLPA), Section 301 tariff compliance, and voluntary ESG due diligence all require documented evidence of where products actually originate. CBP manifest data provides an independent, government-sourced verification layer for supplier declarations — and a documented audit trail that demonstrates due diligence.
Supplier origin declarations that can't be independently verified
Cross-reference declared origin with the manifest's shipper name, loading port, and vessel route for a public-record verification layer
Transshipment risk with no visibility into actual shipping routes
Analyze manifest records for the shipper's actual loading port vs. declared country of origin — flag inconsistencies for further investigation
UFLPA and forced labor compliance with limited audit trail
Document manifest-based due diligence as part of your UFLPA compliance record — CBP's own data as supporting evidence
New suppliers with unverifiable compliance representations
Search the supplier's manifest history: who else have they shipped to in the US? Any prior CBP holds or detentions? Are their declared origins consistent across buyers?
Board and audit committee asking for supply chain transparency evidence
Build and document a manifest-based supply chain verification process that demonstrates systematic due diligence
For high-risk commodities (steel, aluminum, solar panels, textiles under UFLPA review), cross-reference supplier origin declarations with manifest records. Flag shippers whose loading port is inconsistent with their declared country of origin.
Real example
A compliance officer reviews steel imports from a claimed South Korean mill. Manifest records show the shipper's loading port is consistently a Chinese port, not South Korean. They escalate for further investigation before the entry is filed.
Build a documented due diligence process using manifest data as an independent verification source for supplier origin claims in UFLPA-covered commodity categories.
Real example
For all solar panel suppliers, the compliance team searches CBP manifest records to verify the supplier's US shipping history, consistent country of origin declarations, and absence of Xinjiang-region addresses in the shipper records. This documented process is included in their UFLPA compliance file.
Before approving a new foreign supplier, search their manifest history. Have they shipped to other US importers? Consistently from the same country of origin? Any pattern of detention or holds suggested by gaps in shipping records?
Real example
A new apparel supplier from Bangladesh claims years of US export experience. A manifest search finds minimal US shipping history, with the supplier's name appearing in records as a transshipment intermediary for a sanctioned-country product. Onboarding is paused pending further review.

Map your sourcing categories to UFLPA risk lists, Section 301 tariff categories, and voluntary ESG risk frameworks. These are your priority verification targets.
For each high-risk supplier, pull their complete US manifest history. Assess origin consistency, buyer diversity, and shipping pattern regularity.
Compare the supplier's declared country of origin with their loading port in manifest records. Inconsistencies (e.g., Chinese loading port for "Vietnamese" product) are red flags for transshipment.
Export manifest records as supporting evidence in your compliance file. CBP's own public records are a credible independent source for origin verification.
For flagged suppliers, escalate to legal/customs counsel before filing entries. Consider requesting additional origin documentation, factory audits, or shifting to alternative suppliers.
CBP's own public manifest records as documented due diligence evidence strengthens your position in any audit or penalty proceeding
Catching origin inconsistencies pre-entry avoids CBP detentions and seizures — which can cost 2-6x the duty savings they were trying to avoid
Documented manifest-based due diligence process demonstrates systematic compliance with UFLPA rebuttable presumption requirements
Manifest-data-backed supply chain transparency reports provide credible ESG supply chain disclosure data
After UFLPA passed, we built a manifest verification step into every new supplier onboarding. We've caught three transshipment red flags in 18 months that would have been CBP detentions. The subscription pays for itself with one avoided detention.
Yes — manifest data is a useful due diligence layer for UFLPA compliance. You can verify supplier origin claims against manifest records, flag inconsistencies between declared country of origin and loading port, and document this verification as part of your UFLPA rebuttable presumption evidence. However, manifest data is one tool — full UFLPA compliance typically also requires factory audits, supply chain mapping, and legal review.
CBP manifest data (from vessel manifests) is public record and shows shipper/consignee, cargo description, and origin. CBP entry data (from formal entry filings) includes invoice values, HS codes, and duty declarations — this is confidential and not publicly available. Manifest data provides the independent public verification layer; entry data is your proprietary filing.
Transshipment involves goods from Country A being briefly transited through Country B to falsely claim Country B origin. Manifest records show the loading port — if a supplier declares "Made in Vietnam" but consistently loads from Chinese ports, that's a transshipment red flag. If a shipper's name matches a known transshipment intermediary, that's another indicator.
Manifest data from CBP is a government public record — highly credible as supporting evidence in a compliance file. Documenting that you searched CBP's own public records and found no origin inconsistencies demonstrates reasonable due diligence. Consult with your trade counsel on how best to integrate manifest verification into your formal compliance program.
