Executive Summary
The global illicit drug market has undergone a fundamental transformation over the past two decades. Where coca and opium poppies once dominated transnational criminal organization (TCO) supply chains, fentanyl and methamphetamine — entirely synthetic drugs — now represent the leading causes of overdose death in North America and the fastest-growing drug crisis in Mexico. This shift carries profound implications for supply chain transparency and economic security, because unlike plant-based drugs, synthetic narcotics require access to precursor and essential chemicals that are globally traded, often uncontrolled, and susceptible to diversion by criminal networks.
Mexican TCOs have become increasingly reliant on importing precursor and essential chemicals from East Asia, principally China and Hong Kong, to supply clandestine fentanyl and methamphetamine laboratories. While law enforcement agencies and regulatory bodies maintain watchlists of known precursor chemicals, this list-based approach has significant blind spots. TCOs deliberately structure their purchases to avoid detection, and many “essential chemicals” — such as glacial acetic acid, tartaric acid, and benzyl alcohol — are widely used in legitimate industry, making shipment-by-shipment screening ineffective.
This investigation brief presents an alternative methodology: analyzing the composition of an entity’s total import portfolio rather than individual shipments. By examining trade data for Mexico-based importers and identifying companies whose imports are heavily concentrated in chemicals known to be used in synthetic drug production, we identified 31 Mexico-based entities at elevated risk of chemical diversion. Our analysis examined 70 known precursors and essential chemicals across Mexican customs records.
Key Finding: Analyzing import portfolio concentration patterns — rather than relying solely on list-based screening or individual shipment analysis — reveals a cohort of high-risk Mexican importers whose trade profiles are inconsistent with legitimate chemical distribution. This methodology is directly applicable to government investigations, supply chain compliance programs, and third-party risk management in enterprise contexts.
Methodology
Our analysis began with a comprehensive inventory of 70 precursor and essential chemicals known to be used in the synthesis of methamphetamine and fentanyl, sourced from DEA guidance, UNODC intelligence, and law enforcement case files. We then queried Mexican customs trade data across a multi-year period to identify all importers bringing in these substances.
Rather than flagging every importer of any precursor chemical — a threshold that would capture thousands of legitimate chemical distributors — we applied a portfolio concentration analysis. For each importer, we calculated what percentage of their total import volume (in kilograms) consisted of the 70 designated chemicals. We then applied a threshold: entities whose essential chemical imports exceeded 50% of their total import portfolio were flagged as higher-risk candidates. This approach assumes that legitimate chemical distributors maintain diverse portfolios across many chemical types, whereas importers focused primarily on drugs-of-abuse precursors will show extreme concentration.
The 50% threshold was selected to balance sensitivity and specificity. A threshold below 30% would capture too many legitimate distributors; above 70% would miss borderline cases in which an entity imports some legitimate commodities as cover. Our analysis included secondary validation by cross-referencing flagged entities against corporate records, shipping lane data, and known TCO networks in Sayari Graph.
Caveats & Limitations
This analysis is constrained by several well-known limitations in trade-based financial crime detection. First, illicit networks frequently mislabel or misclassify shipments in customs declarations, using codes that obscure the true nature of the cargo. A shipment of tartaric acid might be declared as “food additive” or “unclassified chemical” to evade attention. Our analysis is limited to data accuracy as recorded in customs systems; grossly mislabeled shipments fall outside the aperture of this methodology.
Second, our analysis focuses on “supporting chemicals” and “essential chemicals” rather than direct precursors that are explicitly controlled under international treaties (such as acetic anhydride for heroin). The chemicals in our inventory are dual-use substances with legitimate industrial applications. This is intentional: list-based screening of directly controlled precursors is already well-established in government programs. Our contribution is identifying concentration patterns in secondary chemicals that law enforcement agencies may not have systematically analyzed before.
Critical Insight: The 50% concentration threshold is a risk indicator, not a definitive proof of illicit activity. Some of the 31 entities we identified may be legitimate specialty chemical distributors with unusual but legal import profiles. However, when concentration analysis is combined with other risk factors — geographic location in high-trafficking regions, relationships with known criminal networks, shell company structures, and behavioral indicators from trade data — the methodology becomes significantly more predictive.
Results
Our portfolio concentration analysis identified 31 Mexico-based importers whose essential chemical imports exceeded the 50% concentration threshold. These entities are distributed across major importing hubs in Mexico: Guadalajara, Mexico City, Monterrey, Culiacan, and Ciudad Juarez. The full list of all 31 entities, including corporate structure details, beneficial owner information, and supply chain relationships, is provided in Appendix A (available in the full PDF download).
Of these 31 entities, NORTPACIF (Importaciones & Insumos NORTPACIF S.A. de C.V.) emerged as a particularly high-confidence case study due to the extreme concentration of its imports (98% essential chemicals) and clear traceability of its supply chain. We focus our analysis below on this entity and its associated networks.
Case Study: Importaciones & Insumos NORTPACIF
NORTPACIF (full legal name: Importaciones & Insumos NORTPACIF S.A. de C.V., RFC IISN8404036J2) was incorporated on April 5, 2019, in Culiacan, Sinaloa — the capital of Mexico’s primary fentanyl and methamphetamine production region. The company is registered at Blvd. Quazar Industrial Park, a commercial address in central Culiacan that houses multiple shell companies and trading firms.
Between January 2021 and December 2022, NORTPACIF imported 2.3 million kilograms of chemicals valued at approximately $3.6 million USD. Of the company’s 52 recorded shipments during this period, 51 were for essential chemicals directly associated with the synthesis of methamphetamine and fentanyl. This 98% concentration is far above any legitimate chemical distributor’s threshold and strongly indicative of a specialized diversion operation.
The chemicals imported by NORTPACIF were precisely those required for high-volume methamphetamine and fentanyl synthesis. The volume patterns — particularly the massive quantities of tartaric acid and glacial acetic acid — are consistent with industrial-scale drug manufacturing, not legitimate chemical distribution. A legitimate chemical trader selling these substances to automotive, food, or textile manufacturers would typically maintain a more diverse portfolio and show smaller, more varied shipment sizes.
| Chemical | Weight (kg) | Value (USD) | Primary Drug Use |
|---|---|---|---|
| Tartaric Acid | 686,722 | $1,287,427 | Methamphetamine |
| Glacial Acetic Acid | 672,000 | $425,040 | Fentanyl & Methamphetamine |
| N-Methylformamide | 576,000 | $978,240 | Methamphetamine |
| Benzyl Alcohol | 282,240 | $502,387 | Methamphetamine |
| Thioglycolic Acid | 20,000 | $82,000 | Methamphetamine |
| Methyl Thioglycolate | 18,400 | $149,960 | Methamphetamine |
Critical Finding: All but one of NORTPACIF’s 52 recorded shipments were for essential chemicals commonly used in methamphetamine and/or fentanyl synthesis. The single non-matching shipment was a small quantity of ferric chloride. This pattern is incompatible with legitimate chemical distribution and is consistent with a specialized chemical diversion operation supporting high-volume clandestine drug manufacturing.
NORTPACIF’s import data reveals a classic supply chain structure used by Mexican TCOs to access precursor chemicals: the company imports almost exclusively from Hong Kong and China-based suppliers, primarily through freight forwarders and trading companies. This intermediation structure obscures the ultimate end-user and allows the importers to maintain plausible deniability if questioned by customs authorities.
NORTPACIF’s Suppliers
NORTPACIF’s supply chain is dominated by two key suppliers: NEW STAR HOLDING LLC (a South Carolina-based entity) and PANGS CHEM HK LTD (a Hong Kong trading company). These intermediaries act as nexus points between Chinese chemical manufacturers and Mexican importers, taking title to the cargo while obscuring the identity of the ultimate shipper and receiver.
NEW STAR HOLDING LLC is registered in Greenville, South Carolina, at a mail drop address. Our investigation of corporate records and beneficial ownership data linked this entity to ZENG RUIQI, a Chinese national with documented ties to SUNDIA HONG KONG LIMITED, a major chemical trading firm operating from Hong Kong. SUNDIA has long been suspected by law enforcement of facilitating chemical diversion for transnational criminal organizations. The structure — a Chinese national operating through a U.S. shell company to supply Mexican importers — is a textbook example of how global supply chains are weaponized by TCOs.
PANGS CHEM HK LTD is a Hong Kong-registered trading company linked to PANG BIN, a Singapore-based businessman with a documented history of chemical trading. PANGS GROUP, the parent company, operates multiple chemical trading subsidiaries across East Asia. NORTPACIF’s imports from PANGS CHEM were particularly large: shipments of 500,000+ kg of glacial acetic acid in single containers. These volumes are consistent with wholesale chemical distribution for industrial-scale manufacturing operations, not boutique or specialty applications.
What makes this supply chain particularly significant is the cross-jurisdictional nature: Chinese manufacturers → Hong Kong traders → U.S. intermediaries → Mexican importers. Each jurisdiction crossing provides an opportunity for corporate obfuscation, and each adds layers of plausible deniability. A chemical manufacturer in China can claim ignorance of the end-use; a Hong Kong trader can claim the U.S. company is the true buyer; the U.S. company can claim the Mexican importer misrepresented its intentions. By the time the chemicals reach Culiacan, the supply chain is deliberately fragmented across multiple jurisdictions and legal entities.
NORTPACIF’s Extended Corporate Network
NORTPACIF does not operate in isolation. Beneficial ownership and corporate records reveal a family network operating around NORTPACIF and related import operations in Sinaloa. The company is linked to KELLY ROMERO MONTALVO and four other family members who hold direct and indirect ownership stakes. This family cluster also controls or is affiliated with several logistics, distribution, and transport companies operating in the same region:
BELKEL DISTRIBUIDORA is a chemical distribution company registered in Sinaloa and controlled by family members. It appears to serve as a re-export hub, receiving bulk shipments from NORTPACIF and parceling them out to smaller importers and regional distributors. This layering structure is typical of TCO supply chain architecture: a high-volume importer (NORTPACIF) → a regional distributor (BELKEL) → local end-users or clandestine labs.
TRANSPORTES REFRIGERADOS NEISAD and FLETQUIM are logistics firms that specialize in chemical transport. These companies provide cold-chain and hazmat-certified transport services throughout northern Mexico, enabling the movement of chemicals from port cities to interior regions where clandestine manufacturing occurs. The combination of specialized logistics capabilities and family ties to the importing operation suggests deliberate infrastructure construction for supply chain efficiency.
OLA CONSTRUCCIONES is a construction company ostensibly operating in Culiacan. Its presence in the network may indicate ownership of real estate used in the supply chain (warehouses, distribution centers) or may simply serve as a cash-intensive cover business to legitimize family wealth. The pattern — a cluster of family-controlled entities spanning importation, distribution, transport, and construction — is consistent with known TCO operational structures in Mexico.
Critical Nodes in Chemical Supply Chains
The NORTPACIF case reveals why trading companies, logistics firms, and regional distributors function as critical infrastructure for transnational criminal organizations. Unlike manufacturing or cultivation, which require fixed locations and specialized expertise, chemical importing and redistribution can be operated through ostensibly legitimate commercial entities. A trading company’s entire business model — importing bulk commodities and reselling them to regional distributors — is indistinguishable from the operations of a criminal-controlled import operation.
This creates two analytical challenges for law enforcement and compliance professionals. First, identifying high-risk entities requires going beyond traditional list-based screening of regulated precursor chemicals. Our portfolio concentration analysis addresses this by focusing on the composition of an importer’s total portfolio rather than individual shipments. Second, understanding the true ownership and control of trading companies and logistics firms requires access to beneficial ownership data, corporate registries, and network analysis tools — capabilities that are not evenly distributed across law enforcement agencies worldwide. A Mexican state prosecutor may have access to corporate records, but may lack visibility into Hong Kong trader networks or U.S. shell company structures that feed the supply chain.
Enterprise Relevance: This methodology is directly applicable to enterprise supply chain due diligence and third-party risk management. Companies importing chemicals or managing supply chains in Mexico and other transit countries can use portfolio concentration analysis to identify unusually high-risk supplier relationships, implement additional due diligence on specialized chemical traders, and develop monitoring systems for abnormal concentration patterns in their suppliers’ import behavior.
Implications for Economic Security
The NORTPACIF case illustrates a broader vulnerability in the global supply chain architecture: the ability of transnational criminal organizations to access industrial-scale quantities of precursor chemicals through a combination of corporate opacity, jurisdictional fragmentation, and the dual-use nature of the materials themselves. Chemical manufacturers in China have limited incentive to police their customers; Hong Kong traders operate in a jurisdiction with weaker enforcement against drug precursor diversion; U.S. shell companies create legal distance between suppliers and end-users; and Mexican importers are supported by a permissive regulatory environment and weak enforcement in certain regions.
This cross-jurisdictional vulnerability cannot be solved by any single nation’s law enforcement or regulatory system. It requires coordinated intelligence sharing, multilateral agreements on chemical supply chain transparency, and the adoption of advanced analytical methodologies — such as portfolio concentration analysis — that go beyond traditional list-based screening. For government agencies, this investigation brief provides a replicable framework for identifying high-risk chemical importers. For policymakers, it underscores the need for information-sharing agreements between Mexico, the United States, and East Asian jurisdictions focused on precursor chemical trade.
The economic security implications are significant. Mexican fentanyl production has become a primary driver of overdose deaths in the United States and Canada. The chemical supply chains enabling this production are embedded in otherwise legitimate international trade networks. By making supply chain transparency a priority — requiring corporate beneficial ownership disclosure, implementing portfolio-based risk assessments, and enabling law enforcement access to cross-border trade data — governments can disrupt the infrastructure that sustains transnational drug trafficking organizations.

Frequently Asked Questions
Essential chemicals (also called precursors or reagents) are dual-use substances that have legitimate industrial applications but can also be diverted for illicit synthetic drug production. Key chemicals include glacial acetic acid, tartaric acid, N-methylformamide, and benzyl alcohol. These chemicals are widely traded internationally and are often uncontrolled or minimally controlled, making them difficult to monitor through traditional list-based screening alone. Sayari’s trade data enables analysts to identify concentration patterns in import portfolios that may indicate diversion risk.
Trade data derived from bills of lading and customs records provides a detailed view of what companies are importing, from whom, and in what quantities. By analyzing an entity’s total import portfolio rather than individual shipments, investigators can identify abnormal concentration patterns — such as a company whose imports are almost exclusively dual-use chemicals associated with synthetic drug production. This portfolio-based methodology goes beyond traditional list screening to surface entities that would otherwise appear legitimate. Sayari provides access to this level of trade intelligence across Mexico, China, and other key jurisdictions.
Chinese chemical companies are the primary producers and exporters of many precursor and essential chemicals used in synthetic drug manufacturing. These chemicals are often shipped through intermediary jurisdictions — including the United States and Hong Kong — before reaching Mexico, where transnational criminal organizations use them to manufacture fentanyl and methamphetamine. Sayari’s corporate records and trade data help investigators trace these multi-jurisdictional supply chains and identify the ultimate beneficial owners behind shell trading companies.
Sayari provides government analysts and investigators with commercial trade data, corporate ownership records, and network visualization tools that enable them to trace supply chains, identify beneficial owners, and uncover hidden connections between companies and individuals. For counternarcotics investigations, Sayari Graph allows analysts to map chemical supply chains from Chinese manufacturers through intermediary brokers to Mexican importers — revealing the corporate infrastructure that enables chemical diversion for illicit drug production.
Import portfolio concentration analysis is a methodology for evaluating the risk profile of a company based on the composition of its total imports, rather than screening individual shipments against watchlists. When a company’s imports are heavily concentrated in chemicals known to be used in synthetic drug production, it may indicate a higher risk of chemical diversion — especially when combined with other risk indicators such as geographic location, corporate network structure, and supplier relationships. This approach enables investigators to narrow the aperture from thousands of importers to a prioritized set of high-risk entities.
