Copper Oxychloride 50% WG Water dispersible granule · 50% Cu as metal
The same chemistry as the 50% WP, in a form that does not raise dust — which on a product classified harmful if inhaled is a safety argument before it is a convenience one.
Chelora Chemicals is a copper oxychloride 50% WG supplier and sourcing partner serving registrants, distributors and repackers across the United States, with dispersibility, attrition and dustiness agreed before dispatch.

Note: a WG is judged on the granule, not just the assay. Three parameters exist on a water dispersible granule that have no equivalent on a powder: dustiness, attrition resistance — whether the granules survive handling without crumbling back to powder — and flowability. Attrition is the one most often left off a purchase order, and granules that crumble in transit hand you back the dust problem you paid to avoid.
From technical grade to wettable powder
A WP is a milled and surfactant-blended dispersion system. The chemistry is set upstream; the formulation decides whether it actually sprays.
Why it matters: mixing and loading is the highest-exposure step in any spray operation — a granule that does not raise dust removes the exposure at the point it is worst
Why a granule instead of a powder
Copper oxychloride 50% WG carries exactly the same active content as the 50% WP — 50% copper expressed as metal, roughly 850 g/kg of compound, the same contact mode of action, the same FRAC M1 multi-site chemistry. What differs is physical form: the formulation is granulated, so it pours rather than puffs, and the granules disintegrate and disperse on contact with water in the spray tank.
The reason that matters is operator exposure. Copper oxychloride is classified harmful if inhaled, and mixing and loading is the highest-exposure step in any spray operation — the moment a powder is tipped into an open tank. A granule removes airborne dust at precisely that point. It also measures accurately, flows out of the pack cleanly and leaves less residue in the empty container, which matters for triple-rinse disposal.
What a WG specification controls that a WP does not
- Dustiness. The reason the form exists. Specified per order and verified on the granule as supplied.
- Attrition resistance. Whether granules survive handling without crumbling back to powder.
- Flowability. Decides measuring accuracy and how cleanly the pack empties for triple-rinse disposal.
- The powder equivalent for comparison: copper oxychloride 50% WP.

Where the granule form earns its premium
Operator safety, closed-transfer systems, accurate measuring and clean disposal.
Operator exposure reduction
Copper oxychloride is harmful if inhaled. A granule removes airborne dust at mixing and loading, the highest-exposure step in the operation.
- Dustiness specified per order
- Attrition resistance held
- Reduces respiratory exposure at tank fill
Dispersibility & tank behavior
Granules disintegrate on contact with water and disperse into suspension, so there is no powder clumping on tank fill.
- Dispersibility specified
- Suspensibility specified
- Do not buffer spray water below pH 6
Accurate measuring & clean packs
Free-flowing granules measure accurately and empty cleanly, leaving less residue for triple-rinse disposal.
- Flowability specified
- 1 kg and 5 kg retail packs
- Artwork to your registrant label
Resistance management programs
FRAC M1 multi-site activity is identical to the WP, so the rotation benefit is unchanged by the formulation.

Importing into the United States
Copper oxychloride 50% WG is a TSCA-regulated chemical substance. Under TSCA section 13 the importer of record, or its authorized agent, must certify to US Customs and Border Protection that each shipment either complies with TSCA or is not subject to it. We confirm the substance's TSCA Inventory status and agree in writing who files that certification before the first consignment moves.
Which party carries that duty follows the Incoterm. On FOB, CFR or CIF terms it is usually the US buyer; on DDP terms it can be the seller or its agent. Safety data sheets and labels are supplied to OSHA's updated Hazard Communication Standard, and the UN 3077 Class 9 transport documentation is prepared before booking.
| Item | How it works |
|---|---|
| Delivery points | Any nominated US plant, terminal or port of discharge |
| Incoterms quoted | FOB · CFR · CIF · DDP |
| Importer of record | Agreed in writing before the first shipment |
| TSCA certification | Section 13 positive certification filed at entry |
| Documentation | Batch COA, SDS, packing list, certificate of origin |
| Pack formats | 25 kg bags or 1 kg–5 kg retail packs |
Note: regional coverage describes where we deliver, not where we hold inventory. Lead time depends on producer scheduling and ocean transit to your nominated US port — we confirm both in the quotation.
How we supply copper oxychloride 50% WG
Chelora Chemicals is a copper oxychloride WP supplier and sourcing partner, not a manufacturer. On a formulated product the assay is the easy part. What decides whether a lot performs is suspensibility, wettability and sieve residue — and we agree those before quoting, not after a field complaint.
We place your order with whichever qualified formulator best matches your specification, your price point and your delivery window, and we settle the FIFRA and import position before booking rather than after.
We are direct about the limit of what a supplier can do here: we do not hold EPA product registrations and cannot lend one. If your intended use needs a registered product in the US, that registration has to be yours.
- Attrition resistance specified, not assumed. Granules that crumble in transit hand you back the dust problem you paid to avoid — and it is the parameter most often left off a purchase order.
- Dustiness verified on the granule as supplied. The whole commercial case for a WG rests on it.
- Dispersibility and suspensibility agreed up front. A granule strong enough to ship must still fall apart in the tank; the two pull against each other.
- The percentage basis stated both ways on every quote. 50% copper as metal, ≈850 g/kg as compound.
- UN 3077 documentation prepared before booking. The granule form does not change the Class 9 classification.
- FIFRA position settled honestly. A pesticide product must itself be EPA-registered for US sale or use. We coordinate; we do not register.

A Class 9 dangerous good - the aquatic hazard drives it
Copper oxychloride is moderately hazardous by ingestion and inhalation, and the classification that governs its logistics is aquatic toxicity. It is very toxic to aquatic life with long-lasting effects, which is what makes it a Class 9 dangerous good rather than an unregulated solid. The summary below is orientation only - the safety data sheet supplied with your specific batch is the authoritative document.
Classified hazards
H302Harmful if swallowed.H332Harmful if inhaled.H315Causes skin irritation.H410Very toxic to aquatic life with long lasting effects.
US registration and import, stated plainly. Copper oxychloride is an EPA-recognized pesticide active ingredient (PC code 023501) covered by the agency's copper reregistration decision, and a technical grade product appears in EPA's product label system. That is not the same as a licence to sell or apply a formulated product here: under FIFRA a pesticide product must itself be EPA-registered for US sale or use, that registration sits with the registrant and never with a raw material supplier, and an imported pesticide requires a Notice of Arrival, EPA Form 3540-1, filed with Customs. We supply material and documentation and will coordinate with your broker; we do not hold registrations and we will not tell you that you can apply unregistered material.
Storage
Store in sealed original packaging in a cool, dry, well-ventilated area, away from food, seed and feedstuffs, and away from strong acids. Keep off the floor and protect from moisture: damp material cakes, and the beta crystal form cakes more readily than the alpha form. Bunded or contained storage is advised because of the aquatic hazard.
Handling
Handle with dust control, impervious gloves, eye protection and respiratory protection where dust is generated; the material is harmful if swallowed or inhaled and irritates skin. Wash hands and face after handling. Prevent any release to drains, watercourses or soil. Follow the exposure controls set out in the batch SDS.
Transport
Copper oxychloride and its formulations are classified as dangerous goods for transport on the basis of aquatic toxicity, normally shipped as UN 3077, Environmentally hazardous substance, solid, n.o.s., Class 9, Packing Group III. This is a real difference from most of our inorganic range: marked and labeled packaging, a dangerous goods declaration and IMDG or DOT-compliant documentation are required. We confirm and document the classification for your specific grade, packaging and destination before booking.
Every batch, documented
We verify documentation before dispatch so there are no surprises at your incoming-goods bench.
Specification agreed
Copper content basis, crystal form, shade, particle size and moisture confirmed against your requirement before order placement.
Producer batch testing
The producing plant tests each batch against the agreed specification before release.
Documentation review
COA, SDS, TSCA or FIFRA position and UN 3077 dangerous goods paperwork checked by our desk before the shipment is booked.
Traceable dispatch
Each shipment is traceable to its producing batch, with full chain-of-custody records on request.
How a copper oxychloride WG is built
A water dispersible granule starts where a wettable powder does — technical copper oxychloride milled to a controlled particle size and blended with a wetting agent and a dispersant. The extra step is granulation: the blend is agglomerated, usually by extrusion, fluid-bed or spray granulation, into free-flowing granules held together by a binder.
The engineering problem is that the granule has to be strong enough to survive handling and weak enough to fall apart in water. Too little binder and the granules attrit back to powder in transit, handing you the dust problem the form exists to solve. Too much and they sit in the tank undispersed. That balance is why dispersibility and attrition resistance are both specified, and why they pull against each other.
The declared content is copper expressed as metal, as on the WP: 50% copper as Cu corresponds to roughly 850 g/kg of compound. The mode of action is unchanged — FRAC group M1, multi-site contact — so the resistance-management positioning is identical to the powder. One label note carries over too: do not buffer the spray water below pH 6.
We do not publish operating process parameters here; this is background only. Full technical documentation accompanies every shipment, and any process-specific detail you need is best confirmed directly with our technical desk.
