Chlorine Tablets Manufacturer — Factory Direct Production & B2B Export

Choosing a chlorine tablets manufacturer is one of the most consequential sourcing decisions a water treatment distributor can make. The supplier you select determines not only your landed cost, but your product consistency, your regulatory exposure, and ultimately your reputation with end users. Everglory Industrial is a factory-direct chlorine tablets manufacturer with more than 15 years of production experience, manufacturing calcium hypochlorite tablets (65-70% available chlorine) and trichlor TCCA tablets (90% available chlorine) at our own compaction facility. We control every step from raw material intake to container sealing, hold ISO 9001 certification, pack exclusively in UN-certified plastic drums for Class 5.1 ocean transport, and export to buyers in over 60 countries. When you buy from Everglory, you buy from the factory — no trading company markups, no third-party quality guessing.

Manufacturing Capabilities

Our production base was purpose-built for solid chlorine products, with dedicated lines for granular material and tablet compaction operating under one quality system:

This capacity allows us to run full-container orders on a single batch, meaning one COA covers your entire shipment — a significant simplification for importers managing regulatory files.

Chlorine Tablets Production Process

As a vertically integrated chlorine tablets manufacturer, we run a six-stage production flow with defined control points between each stage:

• Step 1 — Raw material testing: Incoming calcium hypochlorite and trichlor lots are sampled and tested for available chlorine content and moisture before release to production. Material failing specification is rejected at the gate, not discovered in the finished drum.
• Step 2 — Compaction and granule preparation: Approved material is conditioned to the correct particle size distribution for pressing. Consistent granulometry is what produces tablets with uniform density — the variable that controls dissolution rate.
• Step 3 — Tablet pressing: Rotary and hydraulic presses compact the material into 200g (3-inch) or 20g (1-inch) tablets using calibrated tooling. Compaction pressure and dwell time are locked into the batch record for every run.
• Step 4 — Quality sampling: Operators pull tablets at fixed intervals for weight, hardness, and visual inspection. Deviation beyond tolerance halts the line until tooling is adjusted — tablets are never released on a statistical hope.
• Step 5 — Drum packaging: Finished tablets are filled into UN-certified plastic drums with inner PE liners, weighed, batch-stamped with production and expiry dates, and heat-sealed under low-humidity conditions to protect shelf life.
• Step 6 — Container loading: Sealed drums are palletized or floor-loaded per the DG loading plan, photographed drum-by-drum, inspected, and loaded under a dangerous goods declaration prepared by our own certified staff.

Quality Control System

Our ISO 9001 quality system defines five mandatory checkpoints for every tablet batch manufactured at our facility:

• Checkpoint 1 — Incoming raw material: Iodometric titration verifies available chlorine and moisture before any material enters production; results are archived against the supplier lot number.
• Checkpoint 2 — In-process tablet weight and density: Tablets are sampled every 30 minutes for weight (target tolerance ±2%) and density, catching press drift before it creates an out-of-spec batch.
• Checkpoint 3 — Available chlorine content: Finished tablets from each batch are titrated to confirm the certified 65-70% or 90% minimum; the value is printed on the COA that accompanies your shipment.
• Checkpoint 4 — Dissolution rate test: Laboratory dissolution testing verifies that 3-inch tablets fall within the slow-release profile and 20g tablets within the rapid-release profile specified for each product.
• Checkpoint 5 — Final drum sealing: Before container loading, every drum is checked for liner integrity, net weight, seal condition, batch stamp, and label accuracy — the last line of defense before your goods ship.

Product Range

One factory, two chemistries, every standard water treatment format:

Granular grades are available in 8-30 mesh (coarser, for shock treatment and general dosing) and 20-40 mesh (finer, for faster dissolution in dosing systems). Tablet tooling can be adapted for non-standard weights on request.

OEM Private Label Service

Many of the strongest regional pool and water treatment brands do not own a factory — they own a relationship with one. As your chlorine tablets manufacturer, Everglory provides full OEM private label support:

• Custom branding: Your company name, logo, and contact details printed on drum labels; your brand appears on the product, ours does not.
• Custom drum weights: Standard drums run 5 kg to 50 kg, and we will manufacture to your market's preferred retail or industrial weight, including sizes outside the standard list.
• Label design support: Our team prepares label artwork to your brief and handles required safety pictograms, UN markings, and multilingual text (English, French, Spanish) before printing.
• OEM MOQ: Private label orders start at 5 tons per SKU — deliberately sized so growing distributors can launch a brand without committing to multiple containers.

Certifications & Export Compliance

• ISO 9001: Our quality management system is certified and audited, covering the full production chain described above.
• UN 2880 packaging: All calcium hypochlorite tablet shipments use UN-certified plastic drums rated for Class 5.1 oxidizer ocean transport under the IMDG code; trichlor drums are certified under the corresponding UN classification.
• REACH support: We supply the documentation European buyers need for REACH-related due diligence on imported substances.
• COA and MSDS: A Certificate of Analysis accompanies every batch, and Material Safety Data Sheets are provided in English, French, and Spanish.
• COO and full export set: Certificate of Origin, commercial invoice, packing list, bill of lading, and dangerous goods declaration are issued in-house for smooth customs clearance in all 60+ destination markets we serve.
