Industrial raw materials are the starting point of any manufacturing process. From wheat that becomes flour to polyethylene that shapes a plastic pallet, every industrial product exists because a raw material made it possible first.
Knowing which examples of raw materials exist in each sector enables better procurement decisions, more resilient supply chain design, and the right choice of logistics packaging to protect and transport that raw material, or the product derived from it.
In this article you will find a practical classification of the main types of industrial raw materials, with real examples by sector and their relevance for logistics and packaging.
What you'll find in this guide: types of raw materials according to their origin, real examples in the food, chemical, pharmaceutical, automotive and logistics packaging sectors, and a summary table for quick reference.
Types of industrial raw materials by origin
The most widely used classification groups industrial raw materials into three broad categories according to how they are obtained:
| Type | Origin | Representative examples |
|---|---|---|
| Natural | Direct extraction from nature (plant, animal or mineral) | Wheat, wood, cotton, iron, crude oil, water, salt |
| Synthetic or petrochemical | Derived from processing oil or natural gas | Polyethylene (HDPE, LDPE), polypropylene (PP), PET, PVC, ethylene, propylene |
| Recycled or recovered | From recycling end-of-life materials | Post-consumer plastic (rHDPE, rPP), recycled steel, recycled paper, glass |
| Semi-processed | Materials that have undergone a first transformation and serve as input to another industry | Steel sheets, polypropylene granules, fruit juice concentrate, wheat flour |
This distinction matters because the type of raw material determines its handling, storage, temperature requirements, packaging type and the logistics requirements needed to guarantee its integrity.
Examples of raw materials in the food sector
The food industry is one of the world's largest consumers of raw materials. Its inputs range from agricultural commodities to chemical synthesis additives. Hygiene and food safety requirements directly determine what type of packaging and pallets can be used.
Food industry: some raw materials we can find:
- Cereals and derivatives: wheat, corn, rice, barley, oats, rye. Base of flours, starches, glucose syrups.
- Oilseeds: soybean, sunflower, palm, rapeseed. Source of vegetable oils and fats for processing.
- Animal proteins: whole milk, whey, egg powder, meats (carcass, deboned, minced).
- Sugars: sucrose (beet or cane), glucose, fructose, syrups.
- Additives and functional ingredients: salt, citric acid, ascorbic acid, soy lecithin, carrageenans, pectins, emulsifiers.
- Flavours and spices: natural extracts, oleoresins, synthetic flavours.
Logistics implication: food raw materials require pallets compatible with temperature-controlled environments, washable and without risk of cross-contamination. Plastic pallets, splinter-free and non-moisture-absorbing, are the safest option for companies certified in IFS or BRC or with high hygiene and food safety requirements.
Examples of raw materials in the chemical and petrochemical sector
The chemical industry transforms raw materials, mainly derivatives of oil and natural gas, into the polymers, solvents and specialties that the rest of industry needs. It is the sector on which most modern industrial packaging depends, directly or indirectly.
⚗️ Chemical industry: key raw materials it trades
- Olefins (polymer raw materials): ethylene, propylene, butadiene. Base of HDPE, LDPE, PP and synthetic rubber.
- Aromatics: benzene, toluene, xylenes. Starting point of PET, polystyrene, nylon, PVC.
- Industrial acids and bases: sulfuric acid, hydrochloric acid, nitric acid, sodium hydroxide (caustic soda), potassium hydroxide.
- Industrial gases: chlorine, hydrogen, nitrogen, oxygen. Crucial in synthesis and controlled atmospheres.
- Base polymers: HDPE, PP, PET, PVC, PS, ABS granules. Raw materials for the plastics industry.
- Solvents: ethanol, acetone, toluene, MEK. Present in paints, adhesives, coatings and pharmaceuticals.
Logistics implication: many chemical raw materials are traded in bulk or big bags, so pallets must withstand non-uniform and unstable loads in addition to resisting spills without absorbing or degrading.
Examples of raw materials in the pharmaceutical industry
The pharmaceutical sector works with some of the highest value-added and most strictly regulated raw materials in the world. Traceability, purity and storage conditions are critical throughout the process.
Pharmaceutical industry: most common raw materials
- APIs (Active Pharmaceutical Ingredients): the active ingredients that give the medicine its efficacy. Can be from chemical synthesis (paracetamol, ibuprofen, acetylsalicylic acid) or biotechnological origin (recombinant proteins, monoclonal antibodies).
- Excipients: lactose monohydrate, microcrystalline cellulose (MCC), magnesium stearate, povidone, mannitol, colloidal silicon dioxide.
- Pharmaceutical solvents: water for injection (WFI), purified water, 96% ethanol, acetone, propylene glycol.
- Encapsulation materials: bovine/porcine gelatin or HPMC (for vegetable capsules), aluminium for blisters, type I and II borosilicate glass.
- Primary packaging materials: HDPE for bottles, PET, pharmaceutical glass, laminated aluminium, silicone rubber for stoppers.
Logistics implication: the pharmaceutical sector requires pallets with complete absence of contaminants and high traceability. Recycled plastic pallets are the standard solution in pharmaceutical industry warehouses.
Examples of raw materials in the automotive industry
Automotive is one of the most raw material-intensive industrial sectors. A modern vehicle combines dozens of different materials, each requiring specific logistics.
Automotive industry: key raw materials
- Ferrous and non-ferrous metals: high-strength steel (AHSS), aluminium (bodywork and engine parts), copper (wiring and electric motors), magnesium (lightened parts).
- Technical polymers: polypropylene (bumpers, interiors), ABS (instrument panels), polyamide/nylon (under the hood), polycarbonate (lights, screens).
- Elastomers: natural and synthetic rubber (tyres, gaskets, hoses), silicone (engine seals).
- Electrification materials: lithium, cobalt, manganese, nickel (lithium-ion batteries), rare earths (electric motors and permanent magnets).
- Glass: laminated and tempered glass for windows.
- Paints and coatings: epoxy resins, polyurethane, pigment fillers.
Logistics implication: automotive works with Just-in-Time or Lean models, where each component and its raw material must be available at the exact time and place. Industrial pallets with high load capacity are the standard in this industry.
Examples of raw materials in the logistics packaging sector
Industrial packaging — pallets, boxes, containers, films — also has its own raw materials. And in this sector, the most important trend is the use of recycled raw materials instead of virgin materials.
Polypropylene (PP)
It is the most widely used polymer in the manufacture of rigid plastic pallets. Its combination of strength, hardness and dimensional stability makes it ideal for supporting temperatures between 0°C and 40°C. Recycled PP (rPP) has a growing presence in the sector, driven by new European regulations such as the PPWR.
High-density polyethylene (HDPE)
The reference raw material for foldable boxes, containers and pallets designed to withstand cold temperatures. HDPE offers excellent chemical resistance and good properties at low temperatures. Both virgin HDPE and post-consumer recycled HDPE (rHDPE) are used in the production of pallets, boxes or containers, with recycled being the preferred option in the circular economy.
Post-consumer recycled plastic
At Naeco, plastic pallets are manufactured mainly from post-consumer and post-industrial recycled plastic: plastic waste from other industries or the end consumer that, after being recycled, becomes the raw material for new pallets. This process closes the circular economy loop and allows the pallet recycled at the end of its useful life to become a new pallet again.
Summary table: examples of raw materials by industrial sector
| Sector | Main raw materials | Supply form | Logistics requirements |
|---|---|---|---|
| Food | Cereals, oilseeds, proteins, sugars, additives | Bulk, big bags, sacks, tankers | Temperature-controlled, IFS/BRC hygiene, splinter-free pallets |
| Chemical / Petrochemical | Ethylene, propylene, acids, bases, base polymers | Tankers, IBC, cylinders, bulk granules | Chemical resistance, high load requirements, unstable loads |
| Pharmaceutical | APIs, excipients, solvents, glass, pharmaceutical HDPE | Hermetic containers, sterile or GDP conditions | Traceability, sub-zero temperatures, certified pallets |
| Automotive | AHSS steel, aluminium, technical PP, copper, lithium | Coils, sheets, metal containers, industrial pallets | JIT/Lean, high load capacity, 1200×1000 mm pallets |
| Logistics packaging | HDPE, PP, rHDPE, rPP, PET | Granules in big bags or silos | Strict dimensional tolerances, traceability of recycled material |
Recycled raw material as a competitive advantage
The use of recycled raw materials is moving from a sustainable option to a regulatory and competitive requirement. The European Packaging and Packaging Waste Regulation (PPWR) sets minimum quotas for recycled content in packaging marketed in the EU. For plastic logistics packaging, these quotas will increase until 2030.
Companies already working with packaging suppliers that manufacture from post-consumer recycled plastic today have a double advantage: they comply with current regulations and can justify the change in their ESG reports, sustainable supply chain and carbon footprint reduction commitments.
At Naeco, pallets are manufactured with post-consumer recycled plastic, some certified by Recyclass, and the production process operates under Zero Waste certification. In addition, through the Naeco Rewind programme, pallets are bought back at the end of their useful life, recycled and reintegrated as raw material to manufacture new pallets, closing the circle completely.
Frequently asked questions about industrial raw materials
A crude raw material is one that is extracted and traded without prior transformation: iron ore, crude oil, grain wheat or round wood are typical examples. A semi-processed raw material has undergone a first transformation that makes it easier for industry to process: wheat flour, polypropylene granules, cold-rolled steel sheet or fruit juice concentrate would be semi-processed. The difference matters in logistics because each type has different requirements for temperature, packaging, handling and transport regulations. The most common in the food processing industry are cereals (wheat, corn, rice), oilseeds (sunflower, soybean, palm), animal proteins (milk, eggs, meats), sugars (sucrose, glucose, fructose) and additives (salt, citric acid, emulsifiers, preservatives). For the packaging of these products, PE and PP films, plastic boxes and washable plastic pallets complying with IFS and BRC regulations are primarily used. Plastic pallets are manufactured mainly from polypropylene (PP) and, when specific needs exist, high-density polyethylene (HDPE), which can be virgin or recycled. The process starts with the collection and recycling of plastic, which is converted into raw material and subsequently injected into the mould. The resistance of the final pallet depends on the quality of the material, the pallet design and the amount of plastic it contains, among others. Using recycled raw materials (rHDPE, rPP) instead of virgin materials brings three main advantages: reduced carbon footprint (manufacturing with recycled material consumes less energy than starting from crude oil), regulatory compliance (the European PPWR requires minimum recycled content quotas in packaging), and ESG communication value (justifies sustainability commitments to customers, investors and auditors). In terms of technical performance, quality recycled plastic is equivalent to virgin plastic in the vast majority of pallet, box and industrial container applications. By volume, the most consumed raw materials by the chemical industry are ethylene and propylene, the two base olefins from which the most widely used polymers in the world derive (HDPE, LDPE, PP, PVC). Both are obtained mainly from cracking naphtha or ethane from natural gas. At high production volumes, sulfuric acid (the world's largest chemical product by tonnage) and sodium hydroxide also stand out, essential in dozens of industrial processes.What is the difference between crude and semi-processed raw material?
