B2B E-Commerce for the Chemical and Plastics Industry

The distribution of chemicals and plastic raw materials is governed by a dense network of European legislation with direct implications for the e-commerce channel. The REACH Regulation (EC 1907/2006) obliges suppliers to provide current safety data sheets (SDS) for all hazardous substances and mixtures. Every shipment of a hazardous substance must be accompanied by a current, language-correct SDS that must be available to the recipient at least 24 hours before the first delivery. A B2B shop selling hazardous substances must manage SDS documents per article and language version, provide them automatically upon ordering and maintain a complete provision history for audits.

The CLP Regulation (EC 1272/2008) governs the classification, labeling and packaging of chemical substances and mixtures under the globally harmonized system (GHS). Hazard pictograms, H statements and P statements must be correctly displayed in the shop for every product. Classification data is relevant to commercial buyers because it determines operational protective measures, storage classes under TRGS 510 and the need for operating instructions. Our system displays GHS pictograms and signal words prominently on the product page and filters the catalog by hazard classes, significantly simplifying the buyer's work.

In addition to REACH and CLP, the Biocidal Products Regulation (EU 528/2012) applies to parts of the chemical product range, as does the POP Regulation for persistent organic pollutants and the national Chemicals Act (ChemG). For plastic raw materials, specifications such as EN ISO standards, technical data sheets (TDS) and material safety certificates play a central role. Our document module manages SDS, TDS, declarations of conformity and certificates of analysis centrally, linking them to articles, batches and orders. Document versions are synchronized via the ERP interface, ensuring that the currently valid document is always available for download.

The safety data sheet (SDS) is the central information document for every hazardous substance and one of the most important legal instruments of the REACH Regulation. It contains all information on identification, hazards, composition, first aid measures, firefighting, accidental release, handling, storage, exposure, physical properties, stability, toxicology, ecology, disposal, transport and regulation across 16 standardized sections. For e-commerce this means: the SDS must be stored with version control, provided in language-specific form and accompanied by a precise provision record.

Our SDS module addresses this challenge systematically. SDS versions in all relevant languages (at minimum German and English, plus additional languages for export products) are stored for each article. When a new SDS version is issued, the system automatically updates all product pages and notifies customers who carry the product in their regular order lists. When an order is placed, the current SDS is automatically provided as a PDF and archived in the order documentation. This automatic provision record is indispensable during regulatory inspections and audits, replacing labor-intensive manual documentation processes.

SDS management is especially critical for mixtures whose composition changes. When a manufacturer adjusts the formula of a cleaning agent or lubricant and alters the classification, the new SDS must be immediately fed into the ordering process and communicated to all customers who regularly order that product. Our system uses an automatic notification feature for this: customers are informed by email about the new SDS version and see a note about the changed classification when they next place an order. This prevents potential safety risks from outdated protective measures. Learn in our strategic consulting how we integrate SDS workflows into your existing document management process.

In the chemical industry and plastics processing, batch information is essential. Product properties such as viscosity, purity, molecular weight, melt flow index or yellowness index can vary batch-specifically and directly influence processability in production. A quality manager handling a complaint must be able to determine exactly which supplier batch a raw material came from and what analytical values that batch exhibited. This level of traceability requires deep integration between the B2B shop and downstream enterprise resource planning and quality assurance systems.

Our batch module records the supplier's batch number at goods receipt and links it to the internal goods receipt document. The associated certificate of analysis (CoA) is automatically associated with the batch and made available to the customer when ordering. In the customer portal, the buyer can trace for every past order which batch number was delivered and download the associated CoA. This is particularly relevant in pharmaceutical supply chains and food chemistry, where GMP requirements demand complete documentation of the raw material batches used.

The transport of hazardous substances is governed by the European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR). UN numbers, ADR classes, packing groups, dangerous goods labels and transport documents are mandatory for every hazardous goods shipment. A B2B shop shipping hazardous substances must store this information in a structured product master and embed it in the dispatch process.

Our ADR module stores UN number, ADR class, packing group, tunnel restriction code and special provisions in a structured way per article. In the shopping cart, the system automatically checks for segregation restrictions between products of different ADR classes and warns of potentially incompatible combinations. Exempted quantities under ADR 1.1.3.6 are calculated, allowing smaller shipments below the exemption threshold to benefit from simplified transport regulations. The transport document is automatically generated and contains all details required under ADR Section 5.4.1.

For products with a storage class designation under TRGS 510, the shop displays the corresponding storage class (LGK) and provides guidance on quantity thresholds and co-storage restrictions. This information supports the buyer in order management: if an order contains products from incompatible storage classes, they are alerted that the receiving warehouse must meet the appropriate storage prerequisites. The B2B portal functions allow customers to store individual storage class profiles for their various receiving locations, enabling the system to automatically check whether a delivery to the selected location is permissible.

Chemists, process engineers and quality managers have different requirements for a search function than typical B2B buyers. The search for an organic solvent does not start with a trade name but with the CAS registry number or the IUPAC systematic name. A plastic granulate is searched by its MFI value (melt flow index) or impact strength per ISO 179, not by a product name. Our search architecture maps these professional search dimensions and enables technically sophisticated buyers to make precise product selections.

Chemicals and plastic raw materials are traded in a wide variety of packaging sizes and units that differ fundamentally from other B2B product ranges. Liquid chemicals come in small containers (liters, kilograms), drums (200 liters), IBC containers (1,000 liters) and as tanker deliveries (from 20 tonnes). Solids are delivered as granulate, powder or compact form in sacks (25 kg), big bags (500 to 1,000 kg) or silo vehicles. These different packaging types not only have different price structures but also different logistical requirements and hazardous substance classifications.

Our packaging module maps this complexity in a structured way. For each product, multiple packaging variants can be maintained with individual prices, minimum order quantities, lead times and delivery conditions. Unit conversion between kilograms, liters and moles is performed automatically based on the stored density or molar mass. The buyer can choose between packaging sizes as needed without having to calculate manually: they enter their requirement in their preferred unit, and the system recommends the most economical packaging taking into account minimum order quantity and tiered pricing.

The IT landscape in chemical and plastics companies includes, alongside the ERP system, specialized solutions for quality management, laboratory information management and regulatory compliance. The interface work must take into account the specific characteristics of the chemical industry and ensure reliable data flows between the shop, ERP, LIMS and compliance systems.

The biggest challenge in chemical e-commerce is the currency and completeness of regulatory data. SDS versions change when manufacturers adjust formulas or new scientific findings have been incorporated into the classification. GHS classifications are updated by new harmonized classifications (CLH) in Annex VI of the CLP Regulation or by new ECHA scientific assessments. A shop that does not reflect these changes promptly provides customers with outdated safety information and exposes itself to legal risk. Our system can automatically import SDS updates from common document management solutions and use a validation loop to ensure the currently valid document is always linked to the product.

A further industry-specific challenge is managing export and import restrictions. Many chemicals are subject to export control regulations under the Dual-Use Regulation (EU 2021/821) or national chemical weapons control legislation. An internationally operating chemical wholesaler must automatically check at order acceptance whether the product may be exported to the destination country and whether the end customer is unproblematic from an export control perspective. Our system supports these verification processes through a configurable export control flag at product level and the integration of sanctions list checks into the checkout process. We are happy to discuss technical implementation details in a personal consultation.

For plastics processors, additional specific challenges arise: a product range of polymer granulates, compounds and additives often comprises thousands of articles with closely related technical specifications. Without structured filter dimensions for MFI, Shore hardness, heat deflection temperature (HDT) and tensile strength, buyers get lost in the catalog. Our PIM integration service ensures that technical data sheets, standards and test values from the ERP or PIM system are correctly displayed in the shop and indexed for technical searches. Performance optimization ensures that search queries across extensive catalogs are answered in real time. How we have approached similar projects is explained on request in our reference conversations.

In the chemical and plastics industry, framework contracts with annual quantities, price escalation clauses and delivery programs dominate the procurement business. Raw material prices are linked to indices such as the naphtha price, ethylene spot or cotton index and can fluctuate week by week. A procurement portal for this industry must map these contract structures and provide buyers with a clear overview of annual contracts, call-off quantities and price indexing.

Our contract module maps framework contracts with annual quantities, price escalation clauses and fixed delivery windows. The buyer can see in their portal overview what percentage of the annual quantity has already been called off, which delivery windows are still open and when the contract expires. Automatic reminders notify when the minimum purchase quantity is approaching and when contract terms are nearing expiry. Connection via the ERP interface ensures that contract terms are imported from the supplier master and call-off quantities are reflected back into planning. Long-term maintenance covers regular adjustments to new price indices and changed contract structures.
