The Federal Landscape for Hemp Cannabinoid Trade in 2025
The legal and regulatory landscape for hemp cannabinoid imports and exports underwent sweeping changes in 2025. U.S. Customs and Border Protection (CBP) has sharpened its focus on shipments of hemp-derived cannabinoids, especially those containing or marketed as THCa and other potentially intoxicating compounds. Businesses in this space face greater scrutiny, more sophisticated enforcement technology, and evolving red flags that can trigger a costly seizure or denial of entry.
This guide draws on regulatory insights, recent guidance, and industry trends as of September 2025, detailing what importers and exporters need to know and do to stay compliant—without offering legal advice.

CBP’s Intensified Scrutiny: What Changed in 2025
CBP’s approach to hemp imports and exports has grown stricter in 2025, especially for shipments involving THCa or products that may be intoxicating even if delta-9 THC content is below 0.3%. Key triggers include:
- Total THC Testing: Border labs now regularly assess total THC content via decarboxylation potential (not just delta-9 levels)
- Product Formulation and Labeling: Products labeled for human consumption, novel foods, or with euphemistic descriptions (e.g., “aromatic flower,” "herbal smoke") face added scrutiny
- Red Flags: CBP detains shipments where labels, documents, or web listings suggest euphoric/intoxicating effects, or when documentation is incomplete, misclassified, or vague
- Enforcement Tech: Improved chemical analysis in border labs enables detection of synthetic/semi-synthetic cannabinoids and conversion potential (especially for THCa)
Seizure Triggers and Enforcement Rationale
CBP has made clear: Stating “0.3% delta-9 THC” alone is not enough. If the product’s total THC—after heating/conversion—exceeds legal limits, it risks seizure. This is especially relevant for THCa flower (since THCa converts to delta-9 on decarboxylation). Misusing tariff/HS codes or failing to provide a robust chain of custody can also trigger red flags.
HS Codes and Product Classification: Do Not Gamble
Correct Harmonized System (HS) codes are vital for avoiding misclassification penalties, detentions, or outright bans of shipments. In 2025, the following best practices are critical:
- Raw Plant Material: Use the precise HS code for unprocessed hemp (typically 1207.99.03 or 1207.99.40 for seeds; consult the latest CBP guidance and the USHTS)
- Plant Extracts and Isolates: Use 1302.19.91 for “other plant extracts,” but be specific in the description (e.g., “Cannabis sativa L. extract, non-psychoactive, GMP produced”)
- Finished Goods: Completed consumer products (e.g., lotions, tinctures) may fall under different codes depending on form, use, and composition
- THCa-Specific Shipments: If your shipment contains high THCa, border agents may classify it as “marijuana” if the total THC potential is over 0.3%. Use of appropriate codes and documentation is your best defense, but be realistic about the risk profile.
Pro tip: When in doubt, consult with a trade compliance professional familiar with U.S. CBP cannabinoid enforcement trends—mistakes can be expensive.
Documentation Musts: COAs, Chain of Custody, and Language
Incomplete or imprecise documentation remains the #1 cause for import/export holds in 2025. Increase your odds of success with:
1. Master Certificates of Analysis (COAs)
- Provide up-to-date, batch-specific COAs from ISO/IEC 17025-accredited labs
- COAs should detail both delta-9 THC and total THC (including THCa) via HPLC or GC methods (with decarboxylation calculation)
- Attach a translation if the COA is not in English
2. Chain of Custody Documents
- Maintain full traceability: from origin (farm/manufacturer), through processing, packaging, and shipment
- Date-stamped documentation for all transfers, storage, and handling events
- Record and disclose all facility licenses, GMP registrations, and handler permits
3. Prohibited Language & Proper Positioning
- Never use “for human consumption” on commercial invoices or shipping labels unless that use is explicitly permitted in the destination market
- Avoid medicinal, euphoric, or intoxicating claims
- Instead, use technical, ingredient-focused descriptions (“botanical extract for cosmetic use” or “not for ingestion”)
For reference, see the FDA’s public health focus page for evolving cannabis-derived product compliance.
Import: Staying Ahead of CBP Seizure Risks in 2025
Importers must take a defensive approach to CBP scrutiny in 2025:
- Supplier Selection: Source only from facilities with proven GMP or equivalent standards (including validated pest, heavy metal, and residual solvent controls)
- NDIN/Novel Food Status: For ingestible products, ensure FDA “NDIN” (New Dietary Ingredient Notification) or relevant “novel food” posture to avoid being flagged as adulterated or unapproved drugs
- Pre-Arrival Coordination: Notify U.S. customs brokers with ample lead time; pre-submit document packets for review when possible
- Border Laboratory Risks: Anticipate random sampling and decarboxylation-based total THC testing—if the documentation, COA, or physical inspection suggests convertible THC levels, even compliant delta-9 will not guarantee release
Key lesson: It’s not about what your paperwork says after the fact—border labs will create their own calculations and interpretations, often erring on the side of seizure if any ambiguity exists.
Export: Meeting Importer and Destination Market Demands
Exporting hemp cannabinoids from the U.S. in 2025 carries equal compliance risk, with added complexity:
- Importer Licenses: Confirm the receiving party is licensed to handle imported hemp/cannabinoids under their national law (not just a generic import license)
- Destination Market Limits: Many countries treat even trace cannabinoids as narcotics or novel foods. Pre-clear with local authorities where possible; verify both mg caps and product category controls
- Documentation Mirroring: Send all information packets (COA, chain of custody, bill of lading, use declaration) both physically and digitally ahead of shipment arrival
Best practice: Use destination-specific, professionally translated paperwork to minimize misinterpretation and seizure risk.
THCa: Why It’s a Red Flag in 2025
THCa-rich hemp flower and extracts have become a flashpoint for CBP in 2025:
- THCa converts to delta-9 THC (the federally controlled intoxicant) on heating—rendering "0.3% delta-9 THC" labels insufficient
- CBP positions now require accounting for the full conversion potential (total THC) in both raw and processed forms
- Products marketed as “legal weed” or with euphemistic descriptors for its effects are almost certain to face seizure or additional testing
- HEMP Act and Proposed Federal Changes: With proposed legislation in Congress focusing on intoxicating hemp derivatives, missteps carry escalating federal risk (learn more)
Pro Tips: Minimizing Red Flags and Surviving Audits
- Always use precise HS codes—generic or catch-all codes draw suspicion
- Prepare a master compliance file with all COAs, supplier licenses, and chain of custody documents ready to present in the event of a hold or audit
- Educate your supply chain—any break in documentation, ambiguous label, or misinformation online can cause a domino effect
- Pre-clear routes with customs brokers by sharing your compliance profile before placing orders
- Stay active in regulatory monitoring—policy is far from settled, and both CBP and FDA are issuing guidance updates quarterly
Takeaways for Hemp Cannabinoid Traders in 2025
- CBP and FDA enforcement in 2025 prioritize total THC over delta-9 alone; THCa-heavy shipments face extraordinary risk
- Misclassification or incomplete documentation is increasingly non-negotiable—be exhaustive and transparent
- Global trade in hemp cannabinoids is highly fragmented—know both U.S. and destination country rules
- Regularly update your compliance protocols to keep pace with evolving CBP, FDA, and legislative requirements
