Maritime transport: strict classification, isolation and emergency management

1. Classification and identification

According to the International Maritime Dangerous Goods Code (IMDG Rules), calcium hypochlorite is classified as a Class 5.1 oxidizing agent, and some products may be a Class 8 corrosive secondary hazard. Specific items should be subdivided according to the effective chlorine content and moisture content (such as UN1748, UN2208, etc.), and the corresponding dangerous goods label and Marine pollutant label should be posted.

2. Packaging and stowage requirements

Packaging specifications: Use containers that meet the packaging class II or III standards, and prohibit packaging bags, medium-sized bulk containers, etc. Hydrated calcium hypochlorite may be exempted from some requirements after being identified by a testing body.

Stowage isolation: only the cabin area is allowed to load, avoiding heat sources and living areas; The container needs to be ventilated and strictly isolated from acids, organic matter and combustibles.

Weight limit: It is recommended that the net weight of a single piece does not exceed 45 kg, and the total weight of a 20-foot container is controlled within 14 tons to avoid heat accumulation.

3. Emergency treatment

Fire treatment: The priority is to use water mist to extinguish the fire, avoid moving the heated package; Open the hatch cover to ventilate the cabin fire.

Leakage treatment: Wear protective equipment, wash the deck leakage with a lot of water, and wear a respirator to enter the cabin leakage treatment.

Air transport: Accurate declaration and special protection

1. Documentation and classification

Dangerous Goods assessment: MSDS (Safety Data Sheet) and dangerous bag certificate are required to confirm compliance with the International Air Transport Association (IATA) dangerous goods classification.

Non-dangerous exemption: If it is proved that it is not dangerous goods through testing, it is necessary to submit a written assessment of the transportation conditions of the goods.

2. Packaging and operation

Moisture and heat protection: Use anti-static, tightly sealed packaging, avoid direct sunlight or high temperature environment.

Magnetic testing: Batches containing metal impurities need magnetic testing to prevent triggering sensitive equipment in the cargo hold.

3. Declare compliance

Avoid false positives: Calcium hypochlorite is often mistakenly reported as calcium chloride, bleaching powder, etc., and it is necessary to clearly mark the ingredient and UN number.

Advance planning: Dangerous goods air transport should apply for shipping space 10-14 days in advance to ensure that the documents are approved.

Customs declaration process: compliance declaration and document management

1. Import declaration points

Access restrictions: Confirm whether the exporting country has access to the target market list.

Document preparation: need to provide certificate of origin, commercial invoice, packing list, health certificate, etc. Dangerous goods also need dangerous bag certificate and MSDS.

2. Export declaration key

Test report: non-dangerous goods need to provide goods transportation conditions identification, dangerous goods need dangerous package certificate and transportation identification report.

Labels and packaging: The outer packaging should be marked with oxidizer and corrosion product labels, and meet the requirements of GB/T 191 "fear of rain" labeling.

Common risks: False reporting or incomplete documentation will result in customs withholding, fines, and even blacklisting.

Comprehensive recommendation: Full chain risk management

Supplier audit: Select a manufacturer with a stable process (Such as sodium process calcium hypochlorite is more stable) to ensure that impurities and moisture are up to standard.

Professional logistics cooperation: Entrust freight forwarders with dangerous goods qualifications to assist in document review and emergency response.

Staff training: strengthen the safety awareness of loading, unloading and storage personnel, and regularly drill fire and leakage emergency plans.

In the context of the increasing complexity of the global supply chain, the safe transportation of calcium hypochlorite requires tripartite collaboration between enterprises, logistics providers and regulators. Compliance declaration, scientific packaging and accurate operation are the core of risk reduction. Through the above measures, enterprises can not only ensure transportation safety, but also improve the efficiency of international logistics and win the trust of the market.
