Executive Summary — How Five Environmental Treaties Meet The Customs Officer At The Border

Five environmental treaties, and the officer at the border who has to apply them.

This lesson examines how the major Multilateral Environmental Agreements (MEAs) — the Basel, Rotterdam, Stockholm, Montreal and Minamata Conventions — operate at Zimbabwe's customs frontier. Each treaty controls the cross-border movement of a class of environmental risk: hazardous wastes, dangerous chemicals subject to prior informed consent (PIC), persistent organic pollutants, ozone-depleting substances and mercury. ZIMRA is the border-end of that global governance system, verifying the permits, PIC documentation and notifications the conventions require before a controlled consignment may enter or leave.

For the customs officer the practical task is to recognise which convention a consignment engages, call for the correct EMA or MCAZ permit, and apply the right response — release on documentary compliance, hold on RIH, or seizure — working through inter-agency reach-back to the Environmental Management Agency and the Medicines Control Authority. The lesson ties each convention to its domestic implementing instruments and to the customs sections that give officers their enforcement powers.

A.1 Customs as the Border-End of Global Environmental Governance

Module L2.9 examines the architecture of Multilateral Environmental Agreements (MEAs) as they operate at the customs frontier. The world has constructed, over the past five decades, an interlocking system of treaties addressing transboundary environmental and chemical risks: hazardous waste, biodiversity, ozone depletion, mercury, persistent organic pollutants, hazardous chemicals, endangered species, chemical weapons, and biological weapons. Each treaty operates through international commitments, domestic implementing legislation, and — critically for this module — border control.

Customs administrations are the operational arm of MEA implementation: the point at which restricted substances and species are intercepted, controlled, or rejected.

The role of customs in MEA implementation is collectively known as Green Customs. The Green Customs Initiative, supported by UNEP, WCO, and treaty secretariats, recognises customs administrations as central to the integrity of the international environmental regime. Without customs enforcement at the border, the treaty obligations are unenforceable in practice — products can move, species can be smuggled, hazardous wastes can be dumped. With customs enforcement, the treaty obligations become operationally real.

For Zimbabwe, MEA enforcement spans all major ports of entry. Beitbridge handles the principal volume of goods that may attract MEA scrutiny; Forbes and Plumtree process specialised flows; the airports manage CITES species, mercury, and chemical risks; and the borders generally operate at the intersection of multiple agencies including ZIMRA, the Environmental Management Agency (EMA), the Parks and Wildlife Management Authority (PWMA), the National Biotechnology Authority (NBA), the National Ozone Office, and the Ministry of Agriculture (Pesticides Control).

A.2 Why Level 2 MEAs Matter

Three reasons drive Level 2 mastery. First, MEA enforcement is a high-priority national obligation; failure produces both environmental harm and reputational damage in international fora. Second, the treaty architecture has expanded substantially:

  • the Minamata Convention (mercury
  • in force 2017)
  • the Stockholm POPs amendments
  • the Basel ban amendment on hazardous wastes
  • the post-January 2025 Basel amendments on e-waste each represent significant expansions of customs scope

Third, the convention obligations are operationally specific — particular permits, particular labels, particular procedures, particular forms of certification — and the practitioner must be fluent in the operational details to enforce effectively.

A.3 Position and Learning Objectives

Module L2.9 sits in Phase L2-C (Specialist Topics). It complements Module 14 (Controls Level 1) and Module 15 (CITES Level 1) on the introductory side, and Module L2.10 (STCE/CBRN Level 2) on the security-controls side. By the end of this module, the reader should be able to:

  • articulate the nine principal MEAs covered by the Green Customs Initiative — Basel, Cartagena, Montreal, Minamata, Stockholm, Rotterdam, CITES, CWC, BWC — and their respective objectives and target goods
  • apply the Basel Convention framework — hazardous waste, e-waste, plastic waste; PIC procedure; EMA written assent; International Movement Document; Party Status check; SI 10 of 2007 Hazardous Waste Regulations
  • apply the Cartagena Protocol framework — LMOs and GMOs; National Biotechnology Authority Act [Chapter 14:31]; SI 157 of 2018, SI 159 of 2018, SI 160 of 2018; three NBA documents (registration, permit, GMO declaration); Advance Informed Agreement
  • apply the Montreal Protocol framework — ODS and HFCs; SI 49 of 2023; National Ozone Office; quota check; mandatory labelling; refrigeration, AC, aerosol, fire extinguisher equipment risks
  • apply the Minamata Convention framework — mercury and mercury-added products; intelligence-led detection (ASGM-focus); SI 247 of 2000 mercury in skin lightening products
  • apply the Stockholm Convention framework — POPs; legislative gap recognition; identify-flag-refer to EMA; SDS scrutiny
  • apply the Rotterdam Convention framework — PIC for hazardous chemicals listed in Annex III; PIC Circular; EMA as Designated National Authority; SI 144 of 2012 Pesticides Regulations
  • apply the CITES framework (Module 15 Level 1 introduces) at advanced level — Appendices I, II, III; PWMA permits; CITES/Basel overlap (cyanide poisoning in elephant poaching)
  • apply the Chemical Weapons Convention (CWC) framework — chemical weapon declarations; document checks; OPCW interface
  • articulate the principle of "synergies over segregation" — the integrated treatment of related conventions (BRS — Basel/Rotterdam/Stockholm) and the trend toward consolidated implementation
  • handle the inter-agency coordination architecture — ZIMRA, EMA, PWMA, NBA, National Ozone Office, OPCW NA, BWC NA — at the border

C. Detailed Conceptual Explanation: Detailed Conceptual Explanation

Which goods are controlled, and what documentation releases them.

C.1 The Basel Convention — Hazardous Waste

C.1.1 Core Objective and Targets

The Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and Their Disposal (1989, in force 1992) aims to reduce the movement of hazardous waste and ensure that what does move is managed in environmentally sound manner. Target goods: hazardous wastes, e-waste, incinerator ash, certain plastic waste.

C.1.2 Prior Informed Consent (PIC) Procedure

Movement of hazardous waste requires written consent from the receiving country and all transit countries before shipment can occur. ZIMRA's primary checks at the border:

Written assent from EMA. The importer must present a document showing EMA has given explicit written consent for the shipment. This is the primary check.

International Movement Document. The shipment must be accompanied by this document tracking waste from origin to final disposal or recycling facility.

Proof of Party Status. The exporting country must be a Party to the Basel Convention. Non-Party imports are categorically refused.

C.1.3 E-Waste and Plastics — Post-January 2025 Amendments

Significant Basel amendments effective January 2025 expanded the PIC procedure to all e-waste, regardless of whether the shipment is declared for "recycling" or "refurbishment". This is a critical evolution: previously, e-waste declared for refurbishment could move with limited control; now, all e-waste is subject to strict PIC. ZIMRA must apply rigorous misdeclaration checks against this amendment.

C.1.4 EMA Licensing

Under SI 10 of 2007, imported "Convention Wastes" can only be received by a facility holding a valid Blue, Green, Yellow, or Red EMA Licence for waste disposal. ZIMRA verifies the receiving facility licence at the border; without a valid licence, the consignment cannot lawfully enter.

C.1.5 ZIMRA Risk Profiling and Enforcement

Risk indicators for Basel-relevant cargo:

  • shipments declared as "scrap", "used goods", or "materials for refurbishment", especially from developed countries
  • repeated importer profiles in the e-waste sector
  • absence of receiving facility EMA licence in declarations
  • declared values inconsistent with described scrap or used goods

Enforcement — if required documents are missing or fraudulent: immediately seize the goods; refer the case to EMA for further action. Joint operations between ZIMRA and EMA are standard for substantial Basel cases.

C.2 The Cartagena Protocol — LMOs and GMOs

C.2.1 Core Objective and Targets

The Cartagena Protocol on Biosafety to the Convention on Biological Diversity (2000, in force 2003) protects biological diversity from potential risks posed by Living Modified Organisms (LMOs) resulting from modern biotechnology. Target goods: LMOs intended for food, feed, or processing (GMOs), and other biological goods.

C.2.2 The Three NBA Documents

All LMO shipments must have three primary documents from the National Biotechnology Authority:

NBA Registration. The company or individual involved in the trade of biological-nature goods must be registered annually with the NBA.

Import/Export Permit. A specific permit, valid for three months, must be obtained from the NBA for each commodity consignment.

GMO Declaration/Certification. A certificate or declaration must accompany the consignment to verify GMO status and compliance.

C.2.3 Advance Informed Agreement (AIA)

AIA is the procedure used by NBA to assess and approve the first intentional transboundary movement of an LMO, allowing decisions based on a precautionary approach. First-time imports of new LMOs require AIA before commercial movement is permitted.

C.2.4 Verification, Labelling, Penalties

Mandatory labelling under SI 159 of 2018. All imported food and feed must be clearly labelled with their genetically engineered status, regardless of threshold. Provides visible check during physical inspection.

Physical verification. Confirm the physical consignment matches the NBA permit and declaration.

Direct ZIMRA verification. Not just referral — direct confirmation of the required NBA permits and declarations.

Enforcement. If non-compliant, ZIMRA officers have clear authority to seize the goods and initiate legal action in collaboration with NBA.

Penalties. Importing products without a required biosafety import permit carries severe penalties — Level 12 fine or up to 5 years imprisonment, or both.

C.3 The Montreal Protocol — ODS and HFCs

C.3.1 Core Objective and Targets

The Montreal Protocol on Substances that Deplete the Ozone Layer (1987, with subsequent amendments) protects the stratospheric ozone layer by phasing out the production and consumption of Ozone Depleting Substances (ODS) and Hydrofluorocarbons (HFCs). Target goods: CFCs, HCFCs, HFCs, and equipment that depend on them — refrigeration units, air conditioners, fire extinguishers.

C.3.2 Implementation under SI 49 of 2023

SI 49 of 2023 (Prohibition and Control of Ozone Depleting Substances Regulations) provides ZIMRA with a clear and actionable enforcement mandate. Mandatory documentation:

Ozone Office Licence. A mandatory import or export licence must be secured from the National Ozone Office.

Quota Check. The officer must verify that the quantity of substance in the shipment aligns with the quota allocated to the importer by the Ozone Office. This is crucial for managing the national phase-out schedule.

Mandatory Labelling. Products must be clearly labelled to national and international standards, including chemical formulae and safety measures.

C.3.3 Risk Areas and Enforcement

Principal risk areas:

  • refrigeration and cooling equipment
  • air conditioning units for vehicles and buildings
  • aerosol cans and fire extinguishers containing prohibited substances

Enforcement is high-priority due to limited inland monitoring equipment. Penalties: fines up to Level 14 or imprisonment up to 12 months, or both, with possible court-ordered forfeiture to the State.

C.4 The Minamata Convention — Mercury

C.4.1 Core Objective and Targets

The Minamata Convention on Mercury (2013, in force 2017) protects human health and the environment from mercury throughout its life cycle. Target goods: mercury and mercury compounds; products containing mercury (specific batteries, lights, skin creams, certain measuring devices).

C.4.2 The ASGM Enforcement Challenge

A significant portion of illegal mercury trade is tied to the informal Artisanal and Small-Scale Gold Mining (ASGM) sector. This trade often involves:

  • clandestine movements of small, easily concealed quantities
  • absence of formal paper trail typical of conventional goods
  • connections to organised crime networks

C.4.3 ZIMRA Detection and Profiling Strategy

ZIMRA must shift from a traditional verification model to an intelligence-led detection model. Red flags include:

  • undeclared goods at examination
  • sophisticated concealment methods
  • individuals or groups travelling in proximity to known ASGM areas
  • cargo profiles inconsistent with declared purposes

Collaboration with EMA and national law enforcement is essential. SI 247 of 2000 prohibits mercury in certain consumer products (skin lightening creams), supporting Minamata's consumer-product objectives.

C.5 The Stockholm Convention — POPs

C.5.1 Core Objective and Targets

The Stockholm Convention on Persistent Organic Pollutants (2001, in force 2004) protects health and environment by eliminating or restricting the production, use, and trade of POPs. Target goods: highly toxic, long-lasting industrial chemicals and pesticides — DDT, PCBs, Aldrin, Lindane.

C.5.2 The Legislative Gap

Zimbabwe has ratified the Convention but the national legislative framework "falls short" on specific POPs issues. The absence of a dedicated POPs statutory instrument makes immediate prosecution for illegal trade difficult. This is a recognised legislative gap requiring policy attention.

C.5.3 ZIMRA Response — Identify, Flag, Refer

Despite the legal gap, interception is paramount for national security and environmental protection:

  • Identify and Flag — officers must recognise the names and characteristics of POPs listed in Convention Annexes A, B, C
  • Scrutinise Documentation — examine manifests, chemical safety data sheets (SDS), commercial invoices for any mention of controlled chemicals
  • Referral — flag the matter and immediately refer to EMA with all gathered intelligence. This intelligence is vital for tracking trade trends and advocating stronger domestic laws

C.6 The Rotterdam Convention — PIC for Hazardous Chemicals

C.6.1 Core Objective and Targets

The Rotterdam Convention on the Prior Informed Consent Procedure for Certain Hazardous Chemicals and Pesticides in International Trade (1998, in force 2004) establishes PIC for chemicals and pesticides traded internationally. Goal: ensure importing countries have sufficient information to make informed decisions on whether to accept or refuse a hazardous chemical shipment. Target goods: chemicals and pesticides listed in Annex III of the Convention.

C.6.2 The PIC Communication Loop

The Convention Secretariat publishes the PIC Circular every six months, detailing import decisions (Consent, Refusal, Conditional Consent) of all member Parties including Zimbabwe. ZIMRA, as a relevant authority, is a recipient of this information.

C.6.3 ZIMRA Verification

Valid Import Permit. For any chemical listed in Annex III, the officer must confirm the importer has a valid import permit issued by EMA (the Designated National Authority).

Check Against Circular. The permit and import must be consistent with Zimbabwe's formal import response in the latest PIC Circular.

Labelling. Verify shipment labelling and SDS following national regulations (colour-coded triangles, etc.).

C.6.4 SI 144 of 2012 Pesticides Regulations

SI 144 of 2012 is a foundational framework intersecting with Rotterdam:

Mandatory Registration. All pesticides must undergo a rigorous registration process including laboratory analysis and field trials before import or sale.

Local Accountability. Applications for foreign-manufactured pesticides must be submitted by a local representative with a registered company and pre-inspected warehouse.

Export Controls. Exported pesticides must also be locally registered and bear "Zimbabwean labels" ensuring quality and integrity for trading partners.

C.7 CITES — Endangered Species (Advanced)

C.7.1 Core Objective

Module 15 (Level 1) introduces CITES. Module L2.9 covers advanced operational aspects. CITES (1973, in force 1975) ensures international trade in wild animals and plants does not threaten their survival. Target goods: wild animals, plants, and derivatives (trophies, meat, skins) listed in Appendices I, II, III.

C.7.2 The CITES/Basel Overlap — Integrated Threats

Illegal wildlife trade is not isolated. A critical Zimbabwean example: the use of cyanide poisoning to kill elephants. This is simultaneously:

  • a CITES violation (illegal trade in elephant products)
  • a Basel/Rotterdam violation (illegal hazardous substance)
  • a public health risk (cyanide contamination of waterways and ecosystems)

Integrated search must look for suspicious wildlife products in conjunction with unidentified or prohibited chemicals and poisons. The convention boundaries break down at the operational level.

C.7.3 The Role of Taxonomy

Precision is critical:

Scientific name identification. Enforcement relies on identifying the exact species using its scientific name to verify CITES Appendix status and country of origin.

Split-listing awareness. Populations of the same species (e.g., the African bush elephant) may be listed on different Appendices depending on their country of origin. Africa's elephants illustrate this directly: Zimbabwe's, Botswana's, Namibia's, and South Africa's populations are on Appendix II while most other range states are on Appendix I.

C.8 The Chemical Weapons Convention (CWC)

C.8.1 Core Objective

The CWC (1993, in force 1997) prohibits the development, production, stockpiling, and use of chemical weapons and provides for their destruction. Target: scheduled chemicals (Schedules 1, 2, 3) and dual-use chemicals capable of weapons applications. The Organisation for the Prohibition of Chemical Weapons (OPCW) is the implementing body; each Party has a National Authority.

C.8.2 The Critical Document Check

At the border, ZIMRA verifies:

  • CWC import declarations
  • compliance with OPCW reporting requirements
  • end-user verification documents (where applicable)
  • absence of First Schedule chemicals (which are categorically prohibited for non-research purposes)

C.8.3 Border Prohibitions and Enforcement

Strict prohibitions apply to certain CWC-controlled goods. Non-compliance triggers seizure, referral to the National Authority, and where evidence supports, prosecution under the broader Customs and Excise Act offence framework alongside specific CWC implementing legislation.

C.9 The Biological Weapons Convention (BWC)

The BWC (1972, in force 1975) prohibits biological and toxin weapons. Implementation at the border focuses on dual-use biological agents and toxins, requiring inter-agency coordination with health and security authorities.

C.10 Synergies Over Segregation

A guiding principle of the contemporary MEA architecture: synergies over segregation. The Basel-Rotterdam-Stockholm (BRS) Conventions operate under unified Secretariat arrangements; convention obligations are increasingly addressed through integrated operations rather than convention-by-convention silos. For ZIMRA, this means:

integrated training across MEAs rather than convention-specific silos;

integrated risk profiles capturing multiple convention indicators;

integrated documentary checks where multiple instruments apply;

integrated enforcement operations bringing customs, EMA, PWMA, NBA, and other agencies together.

C.11 Inter-Agency Coordination at the Border

MEA enforcement is intrinsically inter-agency. The Zimbabwean architecture:

Agency

Primary MEA Role

ZIMRA First-line interception at border; documentation verification; physical examination; seizure where applicable Environmental Management Agency (EMA) Designated National Authority for Basel, Stockholm, Rotterdam, Minamata; National Ozone Office (Montreal); licence issuance Parks and Wildlife Management Authority (PWMA) CITES implementing authority; permit issuance; species verification National Biotechnology Authority (NBA) Cartagena implementing authority; LMO/GMO permits; biosafety enforcement CWC National Authority OPCW interface; chemical weapons enforcement BWC National Authority BWC interface; biological weapons enforcement Ministry of Agriculture (Pesticides Control) Pesticides registration under SI 144 of 2012 ZRP (Zimbabwe Republic Police) Crime investigation and prosecution support ———————————————— —————————————————————————————————————————–

D. Procedural Walkthrough: Procedural Walkthrough

D.1 Hazardous Waste Importation Walkthrough

From an importer's perspective, importation of materials potentially within the scope of the Basel Convention requires:

  • prior engagement with the Environmental Management Agency (EMA)
  • written EMA assent in advance of shipment
  • an International Movement Document tracking the consignment
  • verification that the exporting country is a Basel Party
  • engagement of a receiving facility with a valid EMA Licence (Blue, Green, Yellow, or Red as applicable). The post-January 2025 Basel amendments expanded coverage to all e-waste regardless of declared purpose

Importers should consult EMA before contemplating any movement that may engage Basel.

D.2 GMO Food/Feed Consignment Walkthrough

From an importer's perspective, importation of food, feed, or seed potentially containing LMOs requires: annual NBA registration of the importing entity; a specific NBA Import Permit valid for 3 months for each consignment; a GMO Declaration/Certification accompanying the cargo; SI 159 of 2018 labelling on the physical product. First-time movements of new LMOs require an Advance Informed Agreement procedure. Penalties for non-compliance are substantial. Importers should engage NBA before commencing any LMO-related trade.

D.3 ODS-Containing Equipment Walkthrough

From an importer's perspective, importation of ODS-containing equipment (refrigeration, air conditioning, fire extinguishers using regulated substances) requires: a National Ozone Office Licence for the importer; quota allocation supporting the specific consignment quantity; mandatory product labelling. Non-compliant consignments face seizure and possible forfeiture under SI 49 of 2023.

E. Worked Examples: Worked Computations and Illustrations

E.1 Worked Example 1 — Basel E-Waste Misdeclaration

A consignment is declared at Beitbridge as "Used Computers for Refurbishment" — 40 tonnes from a UK exporter, valued at US$ 25 000. Documentation includes a UK exporter's commercial invoice but no EMA assent, no International Movement Document, no Zimbabwean receiving-facility licence. The importer claims the goods are exempt from Basel as "used goods for refurbishment".

Apply the post-January 2025 Basel framework. Under the amended provisions, ALL e-waste — including goods declared for refurbishment — is subject to PIC. The importer's exemption claim does not survive the 2025 amendment.

Action:

  • Refuse release
  • Seize the goods (40 tonnes of e-waste)
  • Refer to EMA for action under SI 10 of 2007
  • Document the misdeclaration for prosecution under Section 174 of the Customs and Excise Act (false statement) and any specific SI 10 of 2007 offence
  • Coordinate with UK customs for export-side verification and possible re-export of the cargo to the country of origin under Basel Article 9

E.2 Worked Example 2 — GMO Maize Without Permit

A truck arrives at Forbes from Mozambique declaring 20 tonnes of yellow maize, value US$ 6 000. The importer is registered with NBA but has no specific import permit for this consignment (NBA permits are valid 3 months and consignment-specific). No GMO declaration accompanies the cargo. SI 159 of 2018 labelling absent.

Action:

  • Hold the consignment pending NBA verification
  • Contact NBA for direct confirmation
  • Where NBA confirms no permit issued, seize the consignment
  • Refer for prosecution — Level 12 fine or up to 5 years imprisonment, or both
  • Coordinate with NBA on disposal (typically denaturing or supervised destruction; not permitted to enter consumption channels)

E.3 Worked Example 3 — CITES Elephant Ivory and Cyanide Connection

A truck is stopped at Plumtree showing the following declared cargo: 50kg of unworked ivory; 10 drums of agricultural pesticide. The driver presents a PWMA permit for the ivory (genuinely from a 2023 cull) but the pesticide manifests as "industrial chemicals" without further description.

Apply the CITES/Basel/Rotterdam integrated framework:

  • CITES verification — PWMA permit verified as authentic; ivory tagged and traceable to the cull operation
  • Rotterdam verification — pesticide drums require EMA permit and PIC Circular alignment; verify
  • Cyanide concern — given the integrated threat (cyanide-poisoning of elephants), verify the pesticide is not a cyanide-containing compound capable of wildlife poisoning
  • Take samples of the pesticide for laboratory analysis
  • Where verification supports legitimacy, release; where suspicions are confirmed, seize and refer to PWMA, EMA, and ZRP CID for joint investigation

F. Real-World Applicability: Real-World Applicability

F.1 Importers and Industry

Importers of MEA-relevant goods:

  • refrigeration distributors, agricultural input suppliers, biotechnology firms, mining operations using mercury, taxidermists handling CITES species — must be deeply familiar with the relevant convention frameworks. The compliance discipline includes: securing required permits in advance
  • maintaining annual registrations
  • verifying export-side documentation
  • managing supply chains to avoid transit through non-Party countries
  • coordinating with relevant Designated National Authorities

F.2 Trade Finance and Insurance

Trade finance and insurance functions interact with MEAs through documentation review and risk assessment. Letters of credit for hazardous waste imports without EMA assent should not be honoured; insurance for non-compliant cargo carries forfeiture risk. The compliance framework intersects with banking and insurance discipline.

F.3 EMA, PWMA, NBA, and ZIMRA

The agencies operate together at the operational level. EMA issues permits and licences; ZIMRA verifies at the border; both refer cases for joint enforcement. PWMA and NBA operate parallel architectures. The CBM agenda (Module L2.8) increasingly integrates the inter-agency operations through ZeSW and joint procedures.

F.4 The International Community

Zimbabwe's MEA enforcement contributes to global environmental governance. Compliance with Basel, Cartagena, Montreal, and the other frameworks builds the country's international reputation and supports trade and investment relationships predicated on responsible environmental management.
