Key Takeaway：Chemical raw materials are classified by processing depth into basic (commodity) chemicals and fine chemicals; by chemical composition into organic and inorganic; and by application into general-purpose and specialty. In day-to-day procurement, the Chinese terms "chemical raw materials" (huagong yuanliao) and "chemical feed materials" (huagong yuancailiao) are used interchangeably, but strictly speaking "feed materials" has a broader scope and may include auxiliary and packaging materials. The key to selection is not memorizing category names, but identifying which category your product belongs to and which quality standards and compliance requirements apply.
1. Chemical Raw Materials vs Chemical Feed Materials: Are They the Same Thing?
Bottom line first: in most procurement scenarios these two terms are interchangeable and refer to the same thing. However, in bidding documents or contract clauses, the wording difference can affect the acceptance scope.
If you are the buyer, it is recommended to use "chemical raw materials" when signing the contract and to explicitly list CAS numbers and specifications. Avoid the broad term "chemical feed materials", which could let the supplier slip in auxiliary materials at acceptance. If you are the supplier, using "chemical feed materials" on the quotation can cover more categories, but each item must individually note the product name and CAS number.
| Dimension | Chemical Raw Materials | Chemical Feed Materials |
| Common usage | Basic substances obtained through chemical processing and used in production, e.g. ethylene, propylene, phenol. | Broader scope; besides chemical raw materials it may also include auxiliary materials and packaging materials. |
| Contract scenario | Used in procurement contracts to describe the subject of a single chemical. | Used in bidding documents to cover a comprehensive package of raw materials plus auxiliary materials. |
| HS / tax classification | Corresponds to the "chemical raw materials" and "chemical products" categories under customs HS codes. | May span multiple categories; must be classified according to the specific material. |
| Plain understanding | "The specific chemical I want to buy." | "All the materials I need in my production process." |
2. Core Classification System for Chemical Raw Materials
There is more than one way to classify chemical raw materials; different dimensions are used in combination to pinpoint a product. The three most procurement-relevant dimensions are outlined below.
2.1 Classification by Processing Depth
This is the most practical classification in procurement, because processing depth directly determines the price range, supplier type and quality standards.
| Category | Definition | Typical Products | Procurement Focus |
| Basic (commodity) chemical raw materials | Large-volume bulk products obtained from primary processing of primary energy sources such as petroleum, coal and natural gas. | Three acids and two alkalis (sulfuric acid, hydrochloric acid, nitric acid, caustic soda, soda ash), ethylene, propylene, benzene, methanol. | Price fluctuates; track futures trends; large-volume procurement; logistics cost accounts for a high share. |
| Fine chemical raw materials | High value-added products with specific functions and uses, obtained through deep processing of basic raw materials. | Pharmaceutical intermediates, agrochemical intermediates, dye intermediates, electronic chemicals, surfactants. | Purity grade, COA quality report, custom synthesis capability, small batches, many varieties. |
| New chemical materials | New materials with special performance, positioned between fine chemicals and materials science. | High-performance polymers, specialty coatings, electronic-grade silicon materials, lithium-battery electrolyte. | High technical barrier, fewer qualified suppliers, batch consistency must be verified. |
According to the China Commerce Industry Research Institute, the market size of China's fine chemical industry reached RMB 3.96 trillion in 2024, up 7.5% year on year, and rose to RMB 4.19 trillion in 2025. By segment, new chemical materials account for 29.8%, pharmaceuticals 26.6%, coatings 10.3% and agrochemicals 8.0%. These two major categories together account for over 56%, making them the main battlefield of fine chemical raw material procurement.
2.2 Classification by Chemical Composition
This is the most basic classification, and it corresponds to different inspection standards and storage conditions:
· Inorganic chemical raw materials: compounds without a carbon skeleton, such as sulfuric acid, caustic soda, ammonia water and hydrogen peroxide. Usually monitored for main content, heavy-metal impurities, iron ions and similar indicators.
· Organic chemical raw materials: compounds with a carbon skeleton, such as ethanol, acetone, toluene and ethyl acetate. Additional attention is paid to moisture content, non-volatile matter, color and similar indicators.
· Polymer chemical raw materials: compounds with a high degree of polymerization, such as polyethylene, polypropylene and epoxy resins. Key parameters include melt flow index, molecular weight distribution and density.
2.3 Classification by Application
For the same chemical, different uses can mean quality grades and prices that differ several-fold. For example, industrial-grade ethanol and chromatographic-grade ethanol differ in price by more than ten times. Common application categories include pharmaceutical, electronic, agrochemical, coating, food and reagent grades. Always state the intended grade in your inquiry.
3. Three Trends for Chemical Raw Material Selection in 2026
Trend 1 - Fine chemical demand growth far outpaces basic chemicals. According to Forward Intelligence (Qianzhan), the average gross margin of China's fine chemical industry reached 32.5% in 2025, 15 percentage points higher than basic chemicals. Emerging fields such as new energy (battery materials), AI computing power (liquid-cooling and electronic materials) and biomedicine are seeing annual demand growth of over 30%, while the capacity utilization of traditional bulk chemicals is only 73.0% (National Bureau of Statistics, 2025 data).
Trend 2 - Domestic substitution accelerates, but high-end gaps remain. According to the Zhejiang Petrochemical Industry Association, exports of fine chemical products reached USD 115 billion in 2025, up 26.8% year on year, and the share of high-end product exports rose to 35%. However, core technologies such as high-end photoresist resins and electronic-grade solvents remain monopolized by overseas suppliers, and dependence on imports of high-precision production equipment exceeds 70%.
Trend 3 - Compliance thresholds keep rising. Two policy documents - the Implementation Plan for the Innovation and Development of the Fine Chemical Industry (2024-2027) and the Digital Transformation Work Plan for the Raw Material Industry (2024-2026) - explicitly push the industry toward high-end, green development. The three major industrial bases in the Yangtze River Delta, Pearl River Delta and Bohai Rim contribute 75% of national output (Qianzhan data); environmental and safety supervision in these regions is stricter, and supplier qualification verification standards are rising.
Summary
The core logic for selecting chemical raw materials in 2026: for basic commodities, look at price and logistics; for fine chemicals, look at purity and qualifications; for new materials, look at technical barriers and batch stability.
Frequently Asked Questions
Q: What exactly is the difference between chemical raw materials and chemical feed materials?
Strictly speaking, "chemical raw materials" refers to the basic chemical substances used in production and processing in the chemical industry, while "chemical feed materials" has a broader scope and may include non-chemical substances such as auxiliary and packaging materials. In day-to-day procurement communication the two are largely interchangeable. For contracts or bidding, use "chemical raw materials" and explicitly list CAS numbers and specifications to avoid ambiguity.
Q: How do I distinguish fine chemical raw materials from basic chemical raw materials?
The simplest way is to look at processing depth and added value. Basic chemical raw materials are bulk products obtained from primary processing of petroleum, coal and natural gas (such as the three acids and two alkalis, and ethylene): high output, low price, wide applicability. Fine chemical raw materials are high value-added products obtained by deep processing of basic raw materials (such as pharmaceutical intermediates and electronic chemicals): small output, many varieties, high technical barrier. In terms of price, fine chemical raw materials are usually at least an order of magnitude more expensive than basic ones.
Q: How do storage conditions differ between organic and inorganic chemical raw materials?
Organic chemical raw materials (such as solvents) are mostly flammable and volatile, requiring explosion-proof warehouses, separation from ignition sources and good ventilation; many are also light-sensitive and must be stored away from light. Inorganic chemical raw materials are relatively stable, but strong acids and alkalis need corrosion-resistant containers, and oxidizing materials must be stored separately from reducing materials. Always follow the SDS safety data sheet for specific storage conditions; do not rely on experience.
Q: How do I read the purity grades of chemical raw materials?
Common purity grades from low to high are: Industrial grade (Tech), Chemical Pure (CP), Analytical Reagent (AR), Guaranteed Reagent (GR), HPLC grade and Electronic Grade. Prices vary greatly between grades; choose based on actual use rather than always aiming for the highest. For cleaning, industrial grade is enough; for analytical testing, AR or above is needed. The key is to tell the supplier your intended use in the inquiry and let them recommend the right grade.
Q: Will quality be the same across batches from the same product?
For the same brand and specification, batch-to-batch quality is usually stable. But chemical products can vary slightly between batches due to raw-material sources and process parameters. It is recommended to run a small-batch verification before key experiments or production, and to state batch-consistency requirements in the inquiry. On arrival, check the test data on the COA report to confirm that key indicators are within acceptable ranges.
