The IC55UP is a tri-layer, ultra-pure HDPE 55-gallon drum designed for electronic wet chemicals that require controlled particle counts and low metal extractables. A virgin inner liner and an integral sump support product-contact purity and more complete recovery, and UN/DOT approval covers transport of Group II and Group III chemistries.
Three layers isolate colorants and UV stabilizers in the exterior structure, away from the product-contact layer.
The inner liner contacts the chemical with high-purity HDPE, supporting low particles and extractables. Three resin grades are available to match your specification.
Drums are finished in a Class 1000 clean-room environment, and cleanliness is verified in our Class 100 liquid particle-count laboratory testing.
Recovery geometry below the bung supports more complete extraction and lower residual volume.
Every IC55UP configuration is UN/DOT tested and certified, and each ships under the marking embossed on the drum itself.
Tested and certified for transport of Packing Group II and Group III chemistries, with and without a dip tube.
PG II & III · Dip tube: certified with & withoutHandles higher-pressure service, supporting global transport.
Higher-pressure chemistries · Global shipmentCertifications are documented per model and configuration; an approval for one configuration is never extended to another. Certification documents and test summaries for the configuration you intend to qualify are available on request.

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 IC55UP is UN/DOT tested and certified for Packing Group II and Group III chemistries at a 1H1/Y1.9/150 marking. It is not certified for Packing Group I; for high-danger PG I materials, COEXCELL manufactures the two-piece C55UP, which carries the X rating required for that service.
Yes. The IC55UP is UN/DOT tested and certified both with and without a dip tube, so certified extraction configurations are available without changing drums. Tell us your extraction setup and we'll confirm the certified configuration that matches it.
A 300 kPa version, embossed 1H1/Y1.9/300, is available for higher-pressure service, supporting global transport.
Drums are finished in a Class 1000 clean-room environment, and cleanliness is verified in our in-house Class 100 liquid particle-count laboratory testing.
Inner-layer resins for the IC and K55UP product lines are available in three inner-liner resin grades — matched to your extractables requirement rather than a single one-size claim. Grade selection is specified with our team during qualification.
