What 500 Public Shipping Records Reveal About 367 Kratom Shipments Entering the United States
Imagine walking into a gas station.
You see a bottle. A pouch. A capsule.
What you do not see is the international supply chain that delivered it.
Before reaching an American shelf, that product may have crossed an ocean, passed through multiple companies, been documented on customs forms, assigned an international tariff classification, and transported through warehouses thousands of miles away.
This investigation follows that paper trail.
Using publicly available shipping records, trade databases, and customs documentation, we have reconstructed the movement of kratom from Southeast Asian farms to American warehouses. The records do not prove regulatory violations. They do not establish intent. But they do reveal the industrial scale, the recurring patterns, and the documentation choices that define how kratom enters the United States.
This is not an opinion piece. This is an evidence-based briefing for lawmakers, policy analysts, and anyone seeking to understand the kratom supply chain.
This investigation is based on 500 public shipping records, from which 367 unique kratom shipments and 11,390 metric tons of identified imports were derived. The data was compiled from import databases, customs filings, and bills of lading available to the public.
This investigation analyzed hundreds of shipping records to understand the scale and patterns of kratom imports into the United States. The following figures represent the compiled data from public trade databases.
This dataset should not be treated as a complete census of all kratom entering the United States. Not all shipments are captured in public databases, and some records may be incomplete or subject to data-entry errors.
The purpose of this investigation is not to determine guilt. It is to understand how kratom enters the United States.
Shipping records help lawmakers ask better questions about:
How does the Food and Drug Administration review kratom imports? What triggers a review? How many shipments are actually examined?
What information is required on customs forms? How are product descriptions verified? What happens when descriptions are inconsistent?
Which tariff codes are used for kratom imports? Are they consistent? Do they accurately reflect the product being imported?
Who are the major exporters of kratom? Where are they located? How many shipments do they send to the United States?
How old is imported kratom before it reaches consumers? What happens between the port and the retail shelf?
Where does the current regulatory framework fail to provide adequate oversight? What information is simply not available to regulators or the public?
This investigation does not allege wrongdoing. It identifies patterns in public records that raise legitimate questions for policymakers. The answers to these questions require access to customs and FDA records that are not publicly available.
To understand the kratom supply chain, it helps to understand how international shipping works. Every product that enters the United States by ocean freight passes through a predictable series of steps.
The following diagram illustrates the typical journey of a kratom shipment from farm to retail shelf.
Each step generates documentation. The bill of lading is created when the cargo is loaded onto the vessel. The customs entry is filed when the shipment arrives at the port. The importer of record is responsible for clearing the goods through customs.
Public shipping records capture some of these documents, but not all. The records that are available provide a partial view of the supply chain, but they are often sufficient to identify patterns and raise questions.
Think of it as the shipping industry's receipt.
A bill of lading is a legal document issued by a carrier to a shipper that details the type, quantity, and destination of the goods being carried. It serves three functions:
In the context of kratom imports, the bill of lading contains critical information:
The cargo description is where the most interesting details appear. Some bills of lading describe the product as "Mitragyna speciosa" while others use more generic terms. Some explicitly state "Not For Human Consumption" while others do not.
These differences are present in the public records, but the available data do not identify who selected the wording, why it was used, or whether it governed the final customs entry.
Important: Many public manifest records are non-negotiable transportation records and should not be treated as proof of beneficial ownership. A negotiable order bill may function as a document of title, while a non-negotiable sea waybill or straight bill generally operates differently.
Every product that enters the United States must be classified under the Harmonized Tariff Schedule (HTS).
Coffee gets one. Cars get one. Bananas get one. Kratom gets one.
The tariff classification helps U.S. Customs and Border Protection determine duty treatment and collect trade statistics. It may also help route an entry for review, but it does not by itself determine the product's intended use, FDA status, or legal admissibility.
In the records analyzed for this investigation, the overwhelming majority of kratom shipments were classified under:
The official HTS places heading 1211 under plants and plant parts used primarily in perfumery, pharmacy, or insecticidal, fungicidal, or similar purposes.
Some shipments were also classified under HS heading 3101, which covers animal or vegetable fertilizers. This classification has appeared in multiple records and raises questions about how kratom is being categorized for import purposes.
Note: 1211.90 and 3101.00 are six-digit international HS-level headings/subheadings. A complete U.S. HTS classification ordinarily extends beyond six digits. The public records analyzed for this investigation did not always contain the full ten-digit HTS code.
A different tariff heading may affect customs classification, duty treatment, and how the merchandise is described in trade data. The public records do not establish whether the classification altered FDA screening or admissibility review.
FDA Import Alert 54-15 addresses dietary supplements and bulk dietary ingredients that are or contain Mitragyna speciosa.
Products from firms listed on the alert's Red List may be detained without physical examination (DWPE). When similar products originate from firms not yet listed, FDA personnel may refer the entry for center review.
A bill-of-lading phrase such as "not for human consumption" does not, by itself, establish how FDA classified the article or whether the agency had authority to examine, detain, or refuse it. FDA may consider labeling, websites, marketing, product form, importer representations, and other evidence of intended use. Public manifest records do not reveal what evidence accompanied an individual entry.
FDA Import Alert 54-15 is more nuanced than a blanket detention order. It authorizes DWPE for specified products from firms on the Red List, while also providing for center review detention for products from firms not yet listed that appear to be dietary supplements or bulk dietary ingredients.
The question of whether a shipment falls within the scope of Import Alert 54-15 depends on multiple factors, not just the wording on the bill of lading. FDA considers intended use, which can be established by labeling, advertising, and other evidence beyond shipping documents.
The largest curated shipment in this dataset weighed approximately 82.2 metric tons.
The investigation identified 367 unique shipments representing 11,390 metric tons.
To put that in perspective:
This is not a cottage industry. This is industrial-scale agricultural trade.
The records show that kratom enters the United States in large quantities, through multiple ports, from multiple suppliers, and is received by multiple importers. The volume is substantial enough that it cannot be attributed to a few isolated shipments.
The scale of these imports raises questions about supply chain oversight. How is this volume being monitored? How are shipments being classified? How are they being inspected?
The public shipping records analyzed for this investigation reveal several patterns worth noting.
Some records say "Mitragyna speciosa." Others say "kratom." Some say "herbal powder." The descriptions are not consistent.
Most shipments use HS 1211.90. Some use HS 3101 (fertilizer). The choice of heading varies by shipment.
Multiple U.S. companies appear as importers of record. Some import large volumes, others import small quantities.
Exporters are based in Indonesia, primarily in West Kalimantan. Some suppliers appear repeatedly, others only once.
Several Indonesian companies appear in multiple shipments. They appear to be commercial exporters with established relationships.
The volume of shipments, the size of containers, and the frequency of imports indicate a mature supply chain.
These patterns do not prove wrongdoing. But they do establish that kratom is being imported at industrial scale through a variety of channels and with varying documentation choices.
This is very important.
The public shipping records analyzed for this investigation do not establish:
The records are a starting point, not a conclusion. They identify patterns worthy of investigation, but they do not prove anything about how any particular shipment was handled by regulators.
To determine how FDA evaluated any specific shipment, one would need access to FDA records, customs entry documents, and potentially court records. Those documents are not publicly available in most cases.
The records analyzed for this investigation raise several questions that policymakers and regulators may wish to explore.
Were any of these shipments reviewed by the Food and Drug Administration? If so, what was the outcome?
How many shipments were actually examined by FDA? How many were detained?
Why do some bills of lading describe the product as "Mitragyna speciosa" while others use generic or vague terms?
Why do some shipments state "External Use" or "Not For Human Consumption" on the bill of lading?
Why are some kratom shipments classified as fertilizer (HS 3101) while others are classified as botanical material (HS 1211.90)?
How long does imported kratom remain in storage before it reaches consumers? What is the age of the material in retail products?
These questions are not accusations. They are legitimate inquiries based on patterns observed in public records. The answers would provide valuable context for understanding the kratom supply chain.
