To obtain IIP Certificate for Class 4 Flammable Solids, the following documents must be submitted to the certifying authority:

The table below shows the IIP UN Mark Certification fees for packaging materials under Normal, Combine, and Tatkal modes. These fees are especially useful for businesses seeking IIP Certification for Class 4 Flammable Solids, helping them plan and understand the certification costs upfront.

Note: The above fee structure represents the Normal Mode, Combined Mode, and Tatkal Mode charges for testing and certification of packaging materials for UN Certificates. If you obtain Combined Tatkal Mode Certification, the Government fee will be 1.5x the Normal Mode charges.

Note: Professional Fee for IIP UN Mark certification Registration Normal mode starts from ₹24,999 whereas the Combine mode (Air & Sea) Fee is ₹37,499.

The Indian Institute of Packaging (IIP) formally certifies packaging used to carry Class 4 hazardous materials with a UN Mark IIP Certificate for Flammable materials. These are substances that can catch fire due to heat, friction, or chemical reactions, such as sulfur, magnesium, naphthalene, phosphorus, and matches.

With regard to transportation laws like the IMDG Code, ICAO/IATA, and India's DGCA rules, this certificate guarantees that the packaging satisfies international UN requirements for safety and compliance.

The packaging must pass stringent performance tests, such as drop tests, leakproof verification, and stacking durability, before it can be issued. Depending on whether the maker is ISO certified, the certificate's typical validity ranges from nine to eighteen months.

The UN Mark IIP Certificate is mandatory for manufacturers, exporters, and logistics providers dealing with the transportation or export of flammable solid substances to ensure legal, safe, and internationally approved packaging.

The UN Mark IIP Certification is a globally recognized packaging certification used to transport hazardous goods. It ensures compliance with United Nations (UN) regulations for the safe handling, storage, and transportation of dangerous materials. Here are the key benefits:

• Enhanced Safety: Certified packaging passes the actual tests such as dropping, pressure, and leakproof efficacy in handling hazardous products that may result in spills, leaks, or contamination.
• International Trade Facilitation: UN certification is accepted by most of the regulatory bodies around the world and reduces the time taken to complete the customs formalities for transporting hazardous materials across borders with minimum legal complications.
• Increased Market Credibility: Certification shows the company’s dedication to quality, safety, and reliability, improving the overall image and perception of the business by its customers, suppliers, and other authorities while enhancing the overall market access.
• Cost Savings: UN approved packages help to avoid fines, legal consequences, and rejected shipments, certification lowers general expenses that are related to compliance violations, damaged goods, and potential danger.
• Competitive Advantage: Obtaining an IIP UN Mark certificate allows businesses to become more competitive and find more customers and partners due to compliance with the requirements for operating at a high level of safety and quality.
• Self-Ignition and Fire Prevention:Class 4 flammable solids and spontaneously combustible substances can ignite without an external ignition source. IIP-certified packaging for Class 4 is tested specifically to prevent self-heating, moisture ingress (for 4.3 water-reactive), and friction-induced ignition (for 4.1 flammable solids).

Class 4 flammable solids include hazardous material that pose significant fire and chemical hazards. Class 4 flammable solids are divided into three sub-divisions:

• Division 4.1 (Flammable Solids): 4.1 flammable solids are readily combustible and may contribute to fire through friction and can cause fire vigorously. Some of the common examples include sulfur, Red phosphorus, magnesium powder, Naphthalene, and safety matches.
• Division 4.2 (Spontaneously Combustible): Materials having a tendency for spontaneous ignition during normal conditions of transportation or heating up in contact with air. Ex- white phosphorus, activated carbon, metal catalysts, fish meals.
• Division 4.3 (Dangerous When Wet): Materials that are combustible, in contact with water or which are liable to become spontaneously flammable or emit gases that are flammable. Common examples include sodium metal and calcium carbide.

Note: Each division has different UN numbers and packaging requirements.

Packing groups (PG) denote the degree of danger presented by the substance. Roman numerals I, II, and III are used to denote 3 packing groups, representing high danger, medium danger, and low danger respectively:

The packing groups for class 4 flammable solids are as follows:

• Packing Group 1 (PG I): (X on UN mark), Highest danger. Ex- white phosphorus (4.2), sodium metal (4.3)
• Packing Group 2 (PG II): (Y on mark), Medium danger. Ex- sulfur (4.1), red phosphorus (4.1), calcium carbide (4.3)
• Packing Group 3 (PG III): (Z on mark), Lowest danger. Ex- safety matches (4.1), naphthalene (4.1)

Note:The packing group determines the robustness of IIP-certified packaging required.

Class 4 Flammable Solids include substances that can ignite easily through friction, heat, or exposure to moisture and air. Here is the list of Class 4 Flammable Solids:

Flammable Solids (Easily combustible and may ignite through friction)

• Common Elements: (Sulfur UN1350), Camphor, (Red phosphorus UN1338)
• Metal Powders: (Magnesium powder UN1418), Aluminum, Zinc, Titanium
• Organic Compounds: (Naphthalene UN1334), Celluloid, Nitrocellulose (Wet), Charcoal
• Everyday Items: Matches

Spontaneously Combustible Substances (Can ignite in air without an external ignition source)

• Reactive Elements: (White phosphorus UN1381, Pyrophoric Iron
• Organic Materials: Coal, Linseed Oil Rags, Cotton Waste, Fish Meal, Oily Fabrics
• Chemical Compounds: Sodium Hydrosulfite, Reactive Carbon Compounds, Ferrous Metal Turnings

Water-Reactive Substances (React violently with water, producing flammable gases)

• Alkali and Alkaline Metals: (Sodium UN1428), Potassium, Lithium, Cesium, Barium, Strontium
• Industrial Compounds: (Calcium carbide UN1402), Magnesium Alloy, Aluminum Phosphide, Zinc Dust

IIP Certificate for class 4 flammable solids, issued by the Indian Institute of Packaging (IIP), is a recognized certification that confirms packaging for dangerous goods including explosives meet prescribed safety, quality, and performance standards for storage and transportation. The validity of class 4 flammable solids depends on the manufacturer’s quality standard and the type of shipment.

• ISO 9000 Certified Manufacturers: 18 months
• General/Non-ISO Manufacturers: 9 months

Certified packages must be utilized for shipment within 18 months for ISO-certified manufacturers and within 9 months for non-ISO certified manufacturers.
