High Temperature & Overhaul Push TCCA/SDIC Costs Higher
Sustained high temperatures have prevailed across domestic industrial zones this summer. As typical high-risk chlorine-based disinfectant materials, TCCA (Trichloroisocyanuric Acid) and SDIC (Sodium Dichloroisocyanurate) produce irritating volatile gases and corrosive substances throughout production. Enclosed chemical workshops easily accumulate excessive heat, triggering stricter safety control standards and standardized operating restrictions for all production plants.

All frontline staff engaged in production, repackaging, finished goods packing and container loading must wear complete protective equipment, including gas respirators, heat-proof work uniforms and anti-corrosion gloves. Working with full protective gear in high-temperature workshops greatly increases operational difficulty and brings high risks of heatstroke. To comply with safety supervision and environmental protection regulations, all factories are required to implement peak-temperature production suspension and staggered shift work during midday hot hours. This official adjustment greatly cuts effective working hours, resulting in an overall production capacity drop of 30% to 45%.
To stabilize on-site manpower and avoid large-scale staff turnover in high-temperature seasons, all manufacturing bases have launched special summer high-temperature subsidies. Factories also deploy additional rotating workers and arrange night-shift production to compensate for daytime output losses. Expenses on heatstroke prevention supplies, labor protection facilities and occupational safety guarantees further raise unit production costs. Given the persistent difficulty in recruiting professional workers for hazardous chemical workshops, increased labor expenses are inevitably passed down to downstream procurement clients.
Under extreme heat, workshop ventilation systems, equipment cooling devices and exhaust facilities operate 24/7 at full load, leading to a sharp rise in water and power consumption. Production tanks, reaction vessels and delivery pipelines require enhanced daily inspections for static electricity elimination, lightning protection and leakage prevention. Frequent routine maintenance and safety checks further increase comprehensive operational expenditures, driving up the overall manufacturing cost of TCCA and SDIC products.
It is a long-standing industrial practice for domestic chemical facilities to carry out comprehensive annual maintenance during July and August every year. All mainstream TCCA and SDIC manufacturers have officially launched their summer overhaul schedules.

Leading disinfectant chemical factories have started phased shutdowns for equipment inspection, repair and upgrading, with each overhaul cycle lasting 20 days to one month. Meanwhile, upstream supporting facilities for liquid chlorine, caustic soda and cyanuric acid also suspend operation for synchronous maintenance. The tight supply of core raw materials further restricts the output capacity of finished TCCA and SDIC products.
During the overhaul period, manufacturers can barely generate new finished goods output and can only fulfill existing orders relying on pre-stored inventory. The original standard delivery cycle of 7–10 days has now extended to 15–30 days, and certain urgent orders cannot be scheduled for production temporarily. As more factories enter maintenance status, market spot resources continue to decrease, and the delivery time for new incoming orders will be further delayed.
Key raw materials including cyanuric acid, liquid chlorine and caustic soda maintain stable and firm market prices with no room for decline. Combined with the tight supply caused by seasonal factory overhauls, manufacturers have sufficient cost support and market motivation to adjust ex-factory prices upward. Overall TCCA and SDIC market prices will remain firm and rise easily rather than drop.
Current stock resources can still support short-term order delivery. However, with the continuous expansion of overhaul scope and decreasing market supply, mainstream factory quotations are expected to increase starting from August. Delayed order placement will directly lead to higher procurement costs.
July and August are the peak overhaul months of the year. Available production capacity will become increasingly limited as time goes by. The whole supply chain including production scheduling, packaging, customs declaration and container booking will face prolonged cycles and uncertain delays, which may affect customers’ terminal sales and project usage arrangements.
Dangerous goods shipping to Middle East regions is still under temporary restrictions. Even for general cargo shipments, container space is tight with persistent high sea freight surcharges. Late space booking will easily cause additional port storage fees and container detention charges.
1. Please confirm contracts and lock current pricing and production slots for pending orders as early as possible, so as to avoid future price increases and production arrangement shortages.
2. Arrange stocking plans in advance according to your quarterly sales demand. Reserve sufficient time for production, packaging, customs clearance and ocean transportation to prevent seasonal stockout risks.
3. Customized orders with special particle sizes or small-batch packaging will be arranged with lower priority during the overhaul period. Please confirm your customized requirements and schedule production in advance.
Summer high temperature impact and annual factory overhauls are regular seasonal situations in the chemical industry. Tight supply and rising costs are universal market conditions across the whole sector. We(Henan Brilliant Biotech Co.,Ltd) will fully coordinate with our factory to guarantee production priority for regular clients. Nevertheless, production capacity is limited during this period. Earlier order confirmation ensures stable production arrangement, timely shipment and maximum cost savings for your procurement.
