A RainbowForest Solutions Venture Basel Convention Logistics Specialists
TransFrontier Shipments (TFS) manages the complete logistics and compliance chain for cross-border hazardous and non-hazardous waste from initial waste characterisation through Basel Convention prior informed consent permits, IMDG/ADR/IATA/RID-compliant transport, to treatment at approved facilities worldwide.
Our five services cover every stage of the transfrontier shipment process and are fully integrated clients can engage TFS for a single stage or for complete end-to-end management across the entire Basel Convention export and disposal chain.
TFS serves: industrial manufacturers, oil & gas operators, hospitals and healthcare institutions, mining companies, emergency response organisations, governments, and multilateral development organisations in Africa, the GCC, Latin America, Asia, Europe, and beyond.
Every legally compliant transfrontier shipment of hazardous waste under the Basel Convention requires eight sequential stages each with specific regulatory requirements, documentation obligations, and compliance checkpoints that must be completed before the shipment can proceed to the next stage.
TFS manages all eight stages as an integrated service providing clients with a single point of accountability from initial waste sampling through to the final certificate of disposal and competent authority reporting.
Understanding each stage is critical for waste generators planning their first Basel Convention export, or for operators who have experienced non-compliance at a specific stage. Use our Basel Convention Readiness Checklist to assess your current compliance status.
“TFS operates a selective partner programme for regional waste management companies in Africa, the GCC, Latin America, and Asia seeking to build Basel Convention transfrontier shipment capability and to access TFS’s global network of approved treatment facilities and competent authority relationships.”
Partners receive: Basel Convention compliance training and SOPs, interim storage design guidance, repackaging and labelling standard operating procedures, technical coaching on IMDG/ADR classification, and joint project opportunities where TFS provides the cross-border logistics and compliance while the local partner manages in-country collection and pre-shipment operations.
This programme is designed for waste operators, environmental service companies, and industrial waste managers in countries where hazardous waste cannot be treated domestically and must be exported under Basel Convention provisions.
A transfrontier shipment (also called a transboundary movement) is the cross-border transport of hazardous or non-hazardous waste under the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes. Any movement of waste across an international border for disposal, recovery, or recycling that involves waste classified under Basel Convention Annexes I, II, or VIII requires prior informed consent (PIC) from the competent authorities of both the exporting and importing countries, and any transit countries the waste passes through.
Prior informed consent (PIC) is the Basel Convention’s mandatory notification and consent mechanism the legal requirement that a waste exporter formally notifies the relevant competent authorities of the proposed shipment and receives written consent from all of them before any waste is transported. Standard PIC processes take 4–16 weeks depending on the responsiveness of the competent authorities involved. For urgent situations, some countries have expedited procedures. TFS manages the complete PIC process including submission, follow-up communication with focal points, and escalation where consent is delayed.
International hazardous waste shipments are governed by mode-specific transport regulations: IMDG Code (sea freight), ADR (road freight in Europe and beyond), IATA DGR (air freight), and RID (rail freight). These regulations specify the required packaging (UN-certified containers), labelling (hazard class diamonds, UN numbers), documentation (dangerous goods declarations), and transport conditions for each hazard class. TFS applies all four transport regulations depending on the route and transport mode selected for each shipment.
Yes. Cytotoxic pharmaceutical waste is classified under Basel Convention Annex I (Y1 clinical wastes from medical care, Y3 waste pharmaceuticals) and typically requires IMDG Class 6.1 (toxic) or Class 6.2 (infectious substances) packaging for transport. TFS has direct experience managing cytotoxic waste cross-border shipments from hospitals in Lebanon to approved pharmaceutical waste incineration facilities in Europe one of the most complex medical waste streams to manage across multiple jurisdictions.
Under Basel Convention Article 9, any transfrontier movement of hazardous waste without the prior informed consent of all required competent authorities constitutes illegal traffic. The consequences include: mandatory re-import of the waste at the exporter’s expense, criminal liability under national legislation, and financial responsibility for all costs of environmentally sound management of the illegally shipped waste. TFS ensures that no shipment moves before all required consents are in place and documented.
In countries where Basel Convention focal points are under-resourced or where competent authority response is slow, TFS draws on direct experience and established relationships with focal points in 30+ countries. We provide pre-submission consultations with focal point offices, format documentation to match each country’s specific requirements, and manage escalation through embassy and international organisation channels where needed. TFS has successfully managed PIC processes in conflict-adjacent zones including Lebanon and Afghanistan.
TFS’s complete service covers all 8 stages of the Basel Convention export process: (1) waste sampling and characterisation, (2) laboratory analysis and classification, (3) UN-certified repackaging, (4) IMDG/ADR/IATA/RID-compliant labelling, (5) prior informed consent application and competent authority communication, (6) container loading supervision, (7) transfrontier transport management, and (8) treatment at an approved facility with certificate of disposal issuance. Clients can engage TFS for any single stage or for complete end-to-end management.
TransFrontier Shipments (TFS) and BlackForest Solutions (BFS) are complementary ventures within the RainbowForest Solutions Group. BFS provides waste management advisory including Basel Convention compliance strategy, regulatory assessment, circular economy roadmaps, and capacity building. TFS provides the physical logistics and documentation management for actual transfrontier shipments. For clients requiring both advisory and execution for example, a government ministry developing a national hazardous waste export programme BFS and TFS operate as an integrated team.
A TFS field technician or partner laboratory conducts representative sampling of the waste stream at the generator’s site following ISO 18512 and Basel Convention Technical Guidelines protocols for representative sampling of heterogeneous waste. Sampling includes physical and chemical characterisation of each waste fraction to determine Basel Convention Annex I classification, IMDG hazard class, and UN number. The sampling report forms the evidential basis for the prior informed consent application and all subsequent documentation.
Waste samples are submitted to an accredited laboratory for full chemical, physical, and toxicological analysis. TFS coordinates with accredited laboratories globally ensuring analysis reports meet the specific format and content requirements of the importing country’s competent authority. Results determine final Basel Convention Annex III hazard characteristic assessment (H1–H13), confirm IMDG classification, identify any incompatible waste fractions requiring segregated packaging, and establish whether the waste triggers any Basel Convention Annex II “other waste” classification. The laboratory report is a legally required attachment to the PIC notification dossier.
TFS supervises the professional repackaging of hazardous waste into UN-certified packaging appropriate to the waste’s hazard class, physical state, and designated transport mode. For liquid waste streams, UN-certified steel or HDPE drums of appropriate UN packing group are used. Solid waste is packed in labelled fibreboard or plastic containers meeting UN performance standards. For multiple waste fractions, TFS oversees segregation to prevent incompatible materials from co-packaging a frequent source of incidents during transport. All repackaging is documented with a packing list and visual photographic record accompanying the Basel Convention movement documentation.
Every container is labelled in compliance with IMDG, ADR, IATA, or RID requirements depending on the primary transport mode including: UN number diamond label, hazard class placard, subsidiary risk label (where applicable), “ENVIRONMENTALLY HAZARDOUS SUBSTANCE” mark for marine pollutants, Basel Convention movement document reference number, and exporter/consignee identification marks. Labelling errors are a primary cause of shipment rejection at customs and borders TFS’s labelling verification step ensures full compliance before loading. For multi-modal shipments using both sea and road freight, TFS applies dual-regulation labelling to eliminate re-labelling requirements at the point of modal transfer.
TFS prepares and submits the formal Prior Informed Consent (PIC) notification to the competent authority in the country of export triggering the Basel Convention Article 6 consent process. The PIC notification dossier includes: complete waste characterisation report, proposed routing and transport mode, identified receiving facility with its Basel Convention approval status, and detailed disposal plan referencing the applicable Annex IV disposal operation. TFS manages all communication with the exporting country’s competent authority, the receiving country’s national focal point, and any transit country authorities whose consent is also required under Article 6. Written consent from ALL required parties must be received before any waste is loaded for transport. TFS tracks consent timelines, issues escalation communications for non-response, and coordinates with focal points who require additional technical information before granting consent.
Once all required prior informed consents are received and documented, TFS supervises the loading of labelled and packed waste drums into the transport unit whether a 20ft or 40ft ISO container (for sea freight), a specialised road tanker or ADR-compliant curtainsider (for road freight), or an IATA-approved dangerous goods air cargo unit. Loading supervision includes: container integrity inspection, segregation verification (confirming incompatible waste streams are in separate containers), blocking and bracing to prevent movement during transit, and final weight verification against the customs declaration. The TFS supervisor signs the loading confirmation, which is attached to the shipment documentation set and retained for Basel Convention Article 13 annual reporting.
The waste shipment departs under the cover of a completed Basel Convention movement document (Annex VB format) a document that must accompany the waste from point of origin to the final treatment facility and be signed by each party upon receipt. TFS coordinates with the freight carrier to ensure: dangerous goods declarations are issued in the correct format for each transport mode, the Basel Convention movement document is presented at each customs point along the route, transit country border crossings proceed without delay using the pre-approved consent documentation, and any incidents or accidents during transport are reported to all relevant competent authorities as required under Basel Convention Article 13. For multi-transit routes common for shipments from Africa, Central Asia, or the Caribbean to European treatment facilities TFS manages the full document chain across multiple jurisdictions.
Upon arrival at the approved treatment facility, the waste is received and the Basel Convention movement document is signed by the receiving facility confirming physical receipt. Treatment proceeds according to the Annex IV disposal operation specified in the original PIC notification (incineration, co-processing, chemical treatment, secure landfill, or recovery). Upon completion of treatment, the facility issues a formal Certificate of Disposal (or Certificate of Recovery for R-coded operations) confirming that the waste has been treated in an environmentally sound manner. TFS submits this certificate to the competent authority in the country of export formally closing the Basel Convention movement and fulfilling the reporting obligation under Article 6(9). The complete documentation set (PIC notification, consent records, movement document, transport documentation, certificate of disposal) is provided to the client as a compliance archive.
TFS manages the cross-border logistics and Basel Convention compliance for hazardous waste generated by oil and gas operations including produced water treatment sludge, oil-contaminated drilling waste, spent catalysts, NORM (Naturally Occurring Radioactive Material), tank cleaning residues, and off-specification hydrocarbon fractions.
O&G waste streams frequently require multi-modal transport and multi-jurisdiction PIC consent due to the remote locations of generating facilities and the limited treatment capacity in many oil-producing countries. TFS has direct experience managing O&G hazardous waste from GCC operators.
Applicable regulations: Basel Convention Annex I (Y45 — waste mineral oils unfit for their originally intended use), IMDG Class 3 (flammable), ADR, and national environmental laws of oil-producing countries.
TFS manages transfrontier shipments of hazardous waste from mining operations including cyanide-contaminated tailings, heavy metal sludges (arsenic, lead, cadmium), acid mine drainage residues, mercury-contaminated equipment, and spent reagent chemicals.
Mining waste often involves complex multi-country jurisdictions and challenging logistics from remote sites. TFS has managed mercury waste shipments from mine sites in Latin America (Guatemala) coordinating land transport, multi-transit PIC consent, and final treatment in Europe.
Project reference: Mine-related mercury waste, Guatemala (2018–2019) repacking, global logistics, and final disposal.
TFS provides emergency response capability for accidental hazardous waste spills, industrial accidents, and environmental disasters including mercury spills, toxic gas releases, chemical contamination, and oil spills requiring waste recovery and cross-border disposal.
In emergency contexts, TFS can mobilise rapidly to provide on-site containment assessment, emergency repacking of spilled or contaminated material, and expedited Basel Convention processing working with competent authorities in emergency notification procedures where standard PIC timelines are compressed.
Project references: Emergency liquid mercury spill response, UAE (2017) Emirates Cargo. Removal and disposal of toxic gases, UAE (2024–2025).
TFS manages the cross-border logistics and Basel Convention compliance for clinical and medical hazardous waste including cytotoxic chemotherapy drugs and contaminated equipment, infectious clinical waste (Category A and B under IMDG Class 6.2), pharmaceutical expired waste, sharps, and laboratory chemical waste from hospitals and healthcare facilities.
Medical waste cross-border shipments require specialist expertise in IMDG Class 6.1 (toxic) and Class 6.2 (infectious substances) packaging and documentation as well as Basel Convention Annex I classification under Y1 (clinical wastes) and Y3 (waste pharmaceuticals).
Project reference: Cytotoxic hospital waste repacking, global logistics and final disposal, Lebanon, Lebanese American University and other hospitals (2021–2022).
For waste generators whose volumes are insufficient for immediate transfrontier shipment, or whose Basel Convention PIC process is in progress, TFS designs and advises on compliant interim storage and accumulation points ensuring waste is safely contained, correctly labelled, and documented during the waiting period.
Interim storage must comply with national environmental regulations and meet the standards required by the importing country’s competent authority. TFS’s interim storage advisory ensures that the storage period does not create compliance liabilities that could delay or block the eventual export consent.
Applicable: Basel Convention Article 4(8) waste generators bear responsibility for environmentally sound management during storage periods prior to export.
TFS manages transfrontier shipments of laboratory chemical waste, reagent and solvent mixtures, off-specification chemical products, and process residues from pharmaceutical, chemical manufacturing, and research facilities.
Laboratory waste streams frequently include multiple hazard classes in small quantities requiring specialist knowledge of IMDG segregation rules, mixed waste Basel Convention classification, and the identification of the dominant hazard component for UN number and packing group determination.
TFS has experience with multi-component laboratory waste consolidated from multiple generators into single compliant shipments reducing per-unit logistics cost while maintaining full Basel Convention compliance.
