Industry · Chemical
The sector that asks the hardest questions, which is why we like it.
Chemical blenders, coatings plants and lubricant packers are our most demanding customers and our largest source of inbound empties. They need a valid plate, a current test, the right elastomer and paperwork that survives an audit — and they generate a steady stream of containers that are perfect candidates for a closed loop rather than a skip.
Short answer
UN-rated 31HA1/Y reconditioned or rebottled containers with current leakproofness tests, chemistry-matched gaskets and per-unit wash certificates. Plus purchase and retrieval of your empties.

Send the chemistry.
Prior contents and next contents are the two facts that determine grade, wash cycle, gasket and plate requirement. Everything else follows from them.
Compatibility
Gasket selection by chemistry.
Getting this wrong produces a container that weeps within days and a customer who concludes the tote was defective. It almost never was.
| Product family | Gasket | Bottle suitability | Notes |
|---|---|---|---|
| Water treatment chemistry, alkalis | EPDM | HDPE excellent | Standard reconditioned stock |
| Acids (non-oxidising, dilute) | EPDM or PTFE-lined | HDPE good | Check concentration and temperature |
| Oxidising acids, concentrated | PTFE-lined | Case by case | Often requires stainless |
| Lubricants, hydraulic and cutting oils | Viton | HDPE excellent | Extended caustic wash on return |
| Fuels and hydrocarbons | Viton | HDPE good | Check permeation requirements |
| Aromatic and chlorinated solvents | Viton or PTFE | HDPE poor — swells and crazes | Specify stainless |
| Surfactants and detergents | EPDM | HDPE excellent | Extra rinse stages on return |
| Latex and waterborne coatings | EPDM | HDPE excellent | Wash promptly; cured product is unrecoverable |
| Glycols and antifreeze | EPDM | HDPE excellent | Straightforward reconditioning |
What we supply
Outbound to chemical plants

What we take back
Inbound from chemical plants
- Purchase of empties in any condition — what we pay
- Scheduled or one-off on-site collection with sorting included

- Full closed-loop programmes with serial-level registers
- Recovery of containers stranded at your own customers' sites
Questions
Chemical sector, answered.
01Can you supply UN-rated containers for our hazmat shipments?
Yes. We recertify in house, so we can supply reconditioned or rebottled containers with a valid design-type marking and a current leakproofness test, with the record issued against each serial number.
02How do you handle our prior contents on inbound empties?
Ordinary industrial residue is standard work — evacuated under containment at intake and routed to licensed treatment. Regulated residue must be declared before collection so the compliant route is arranged in advance rather than discovered on your dock.
03Will you match gaskets to our chemistry?
Yes, and we would rather you told us the fluid than the elastomer. EPDM, Viton, silicone and PTFE-lined are all stocked. Mismatched gaskets are the most common cause of a container that appears to fail.
04Can you run a closed loop for our fleet?
Chemical manufacturing is the sector where container management works best — repeating lanes, steady volumes and a compliance requirement that makes tracking worthwhile anyway. We hold the register, retrieve, wash, test and return.
05What documentation comes with each container?
Wash certificate naming prior contents and cycle, leakproofness test record where applicable, and a unit record tied to the serial. Sustainability teams also receive diversion statements.
Compatibility guidance here is general orientation, not a substitute for your own testing. Verify material compatibility for your specific formulation, concentration and temperature before committing to a container type.

Compliance workflow
Keeping a hazmat fleet in test without a fire drill.
- 01
Photograph every plate
At intake and at every wash. Eight seconds per unit, and it produces a fleet-wide certification schedule nobody has to walk a yard to build.
Continuous - 02
Build the schedule
Manufacture date plus interval gives you which containers fall due in which quarter. Batch them rather than discovering them.
Once, then maintained - 03
Combine with washing
Testing added to a wash run costs three to five days and one movement instead of two. Units leave your site once.
Per batch - 04
Record against the serial
Test result, date, marking and any repair, held against the unit. The inspector who eventually asks will ask you, not us.
Per unit

01Can you supply UN-rated containers for hazmat shipments?
Yes. We recertify in house, so we can supply reconditioned or rebottled containers with a valid design-type marking and a current leakproofness test, with the record issued against each serial number.
02How do you handle prior contents on inbound empties?
Ordinary industrial residue is standard work — evacuated under containment at intake and routed to licensed treatment. Regulated residue must be declared before collection so the compliant route is arranged in advance.
03Will you match gaskets to our chemistry?
Yes, and we would rather you told us the fluid than the elastomer. EPDM, Viton, silicone and PTFE-lined are all stocked. Mismatched gaskets are the most common cause of a container that appears to have failed.
04What is the biggest avoidable loss in a chemical fleet?
An illegible marking plate. Painting over it, labelling across it or pressure-washing it at close range takes seconds and permanently removes the container from regulated service. It is why fleets shrink faster than anybody planned for.
05Can you run a closed loop for our containers?
Chemical manufacturing is the sector where container management works best — repeating lanes, steady volumes and a compliance requirement that makes tracking worthwhile anyway. We hold the register, retrieve, wash, test and return.
06What if our product crazes polyethylene?
Then the honest answer is a stainless vessel rather than a better plastic container. Aromatic and chlorinated solvents attack HDPE regardless of container condition, and any supplier who sells you the plastic one is selling you a failure with a delay on it.
Next step
Send the fluid, the volume and the plate status.
Three facts and we can specify the container, the gasket, the wash cycle and the testing due — usually in one reply.
