Electrolytes, solvents, and precursor chemistries make a double demand of their packaging: controlled purity at the contact surface, and certified transport for chemistries regulators watch closely. COEXCELL's ultra-pure tri-layer models are built to meet both in one drum.
Contamination introduced by packaging doesn't stay in the drum — it ends up in the cell.
HowTri-layer construction isolates colorants and stabilizers in the exterior structure; the material only contacts a virgin ultra-clean inner liner, verified in the Class 100 LPC laboratory testing.
Battery-supply chemistries ship under scrutiny — the marking has to match the material and the lane.
HowConfigurations are UN/DOT tested and certified under exact embossed markings, with a 300 kPa IC55UP option for higher-pressure chemistries and the X-rated C55UP for Packing Group I chemistries.
Battery supply chains have to answer for every input — including the package it arrived in.
HowEvery drum is molded, finished, tested, and documented in one purpose-built plant in Maumee, Ohio, with rail-served resin supply and a unique traceability label on each IC, K55UP, and C55UP drum.
All three share tri-layer construction, the virgin ultra-clean inner liner, Class 100 LPC verification, and per-drum traceability.

Certifications are stated per model and configuration — never generalized. Full specifications on each model page.
From railcar to shipment, every step happens in our Maumee facility — and every step produces evidence a supply-chain audit can follow.
Cleanliness verified in our in-house liquid particle-count laboratory testing.
Post-forming finishing in a clean-room environment with recorded air-quality readings.
IC, K55UP, and C55UP drums each carry a unique traceability identification label.
Molded, finished, tested, and documented in one purpose-built plant in Maumee, Ohio.
Certification documents, technical data sheets, and test summaries are available for each drum configuration.
See the full quality processElectrolyte and precursor formulations are competitive property — and our process doesn't ask for them.
The packing group, the purity specification you qualify against, and conditions such as pressure, temperature, and specific gravity. The formulation stays yours.
Our team matches those requirements to a model, resin grade, and closure or dip-tube configuration — with its exact UN/DOT marking.
Certification documents, technical data sheets, and test summaries are provided per configuration, so your supplier file has evidence to cite.
Certifications are stated per model and configuration and are never generalized — the same discipline your supply-chain audits apply.
Answers to the questions we hear most before a first quote. If yours isn’t here, the form is the fastest route to a specific answer.
The ultra-pure tri-layer models, routed by requirement: the IC55UP with its 300 kPa option for higher-pressure chemistries, the K55UP where the lowest metal extractables is the priority, and the C55UP where Packing Group I transport requires an X-rated marking. Tell us the packing group, purity specification, and pressure and temperature conditions, and we'll recommend the certified configuration.
Tri-layer coextrusion isolates colorants and UV stabilizers in the exterior structure, so the material only contacts a virgin ultra-clean HDPE inner liner. Drums are finished in a Class 1000 clean-room environment, and cleanliness is verified in our in-house Class 100 liquid particle-count laboratory before testing.
Every drum is molded, finished, tested, and documented in one purpose-built plant in Maumee, Ohio, with rail-served resin supply and per-drum traceability labels on the IC, K55UP, and C55UP models — a single documented U.S. source for packaging supply chains that have to answer for theirs.
No. Quoting is built around requirements: the packing group, the purity specification you qualify against, and conditions such as pressure, temperature, and specific gravity. From those, we recommend a model and configuration with the certification documents to support qualification.
Tell us your purity, pressure, and compliance requirements — you don't need to disclose your chemistry. Our team will recommend a model and configuration, and provide the documentation to support qualification.
