Packaging
Sodium dichloroisocyanurate granules are typically packaged in high-density polyethylene (HDPE) drums, fiber drums, or plastic pails to ensure safe and convenient handling. Common packaging sizes range from 1 kg, 5 kg, 10 kg to 50 kg, catering to various customer needs.
For bulk orders, sodium dichloroisocyanurate granules can be supplied in jumbo bags or customized packaging as per client requirements. Each package is labeled with product information, safety guidelines, and handling instructions to ensure proper use and storage.
Guidance for Use in Swimming Pools
Sodium dichloroisocyanurate is the best choice of quickly raising the chlorine level or daily disinfection of swimming pools and spas. It is quickly dissolved and will not damage liner.
Important
- Use safety gloves and safety mask to protect skins and eyes from contacting with this product.
- Never add sodium dichloroisocyanurate granules when the pool is being used, and always wait at least 30 minutes after added.
- The pool water should be chlorinated at a level of 1.0 to 3.0 ppm while the pH should be kept in the range of 7.2 to 7.6.
Directions for Use
- Fill a plastic bucket with pool water. Add the correct weight of SDIC granules to the bucket, stir gently to mix thoroughly.
- Slowly pour the solution into the pool immediately above the pool return inlet whilst the pool circulation system is running.
- Keep the pool circulation system running for at least 30 min after added.
- Test the pool water to ensure that the required chlorine concentration of 1.0 to 3.0 ppm has been established.
General Precautions
- Ensure that the filter and the pool circulation system work well.
- Always handle products in well ventilated area.
- Always wash hands thoroughly after handling pool chemicals.
Caution

Frequently Asked Questions
Q What is Sodium Dichloroisocyanurate (SDIC) and how does it work?
Sodium Dichloroisocyanurate (SDIC) is a chlorine-based disinfectant and biocide. When dissolved in water, it releases active chlorine, which acts as a powerful oxidizing agent to destroy a wide range of pathogens including bacteria, viruses, fungi, and algae. This makes it highly effective for water treatment and sanitation applications.
Q What is the difference between SDIC Dihydrate Granules and SDIC Granules?
The main difference lies in their available chlorine content and molecular formula. SDIC Dihydrate Granules (CAS No. 51580-86-0) contain 55–56% minimum available chlorine, while standard SDIC Granules (CAS No. 2893-78-9) contain 60% minimum available chlorine. Both appear as white granules with a chlorine odor.
Q What chlorine level and pH range should be maintained when using SDIC in swimming pools?
The pool water should be chlorinated at a level of 1.0 to 3.0 ppm. The pH should be maintained in the range of 7.2 to 7.6 for optimal disinfection performance and swimmer comfort. Regular testing of the pool water is strongly recommended.
Q What industries and applications are SDIC granules suitable for?
SDIC granules are suitable for a wide range of industries and applications, including swimming pool and drinking water disinfection, food processing and beverage manufacturing, livestock and aquaculture farms, hospitals and healthcare facilities, household sanitation, and textile fabric bleaching.
Q What packaging options are available for SDIC granules?
SDIC granules are available in HDPE drums, fiber drums, and plastic pails in sizes of 1 kg, 5 kg, 10 kg, and 50 kg. For bulk orders, jumbo bags or customized packaging options are also available to meet specific client requirements.
Q What certifications does SDIC hold and how should it be stored safely?
SDIC granules are certified under NSF, REACH, and BPR standards. For safe storage, keep the product in a dry, cool, and well-ventilated place away from light, heat, and ignition sources. Store away from strong reducing agents, strong acids, or water, and keep out of reach of children. Always keep the container tightly sealed after use.
