Chemical Import Regulations: Compliance Challenges Across Global Markets

Why Chemical Import Compliance Has Become More Complex

Chemical import compliance just got more complex, with REACH and TSCA updates rolled out quietly but carrying significant implications for electronics supply chains, chemical safety regulations, and chemicals industry trends. In 2025, regulatory compliance has emerged as one of the most critical challenges and opportunities for bulk chemical suppliers, because every market now requires different data, different registrations, and different safety communication, even for the same product. For companies operating in the chemical industry, one of the most significant challenges is navigating the complex and ever-evolving landscape of global chemical regulations, and the cost of getting it wrong is no longer just a fine, it is loss of market access, seizure of cargo at the border, and blacklisting by downstream customers who must report their own supply chain under SCIP, PFAS, and modern slavery rules.

The Global Regulatory Patchwork: REACH, TSCA, UK REACH, K-REACH

From the European Union's REACH regulations to the U.S. Toxic Substances Control Act (TSCA) and various regional adaptations of the Globally Harmonized System (GHS), understanding and complying with chemical regulations is critical for global businesses. The global landscape is fragmented, with each major economy operating its own version of chemical registration, evaluation, and restriction, and even when the names sound similar, the triggers, timelines, and data requirements are very different, creating constant compliance overhead for importers who buy from multiple origins.

EU REACH – No Data, No Market

REACH (Regulation (EC) No 1907/2006) has been in force since 2007 across all EU Member States, and it requires manufacturers and importers to register chemicals, assess their risks, and demonstrate safe use. EU REACH requires manufacturers and importers to register chemicals, assess their risks, and demonstrate safe use, and it applies to any company that manufactures or imports one tonne or more of chemical substances in the EEA, requiring submission of a registration dossier to ECHA. REACH operates on a no data, no market principle with mandatory pre-market registration, meaning that without a valid registration number, the chemical cannot be legally placed on the market, and enforcement is handled by member states through customs checks, inspections, and penalties.

US TSCA – Risk-Based Post-Market Model

The United States regulates chemicals on a federal level under TSCA, administered by EPA, and TSCA takes a risk-based post-market approach where the EPA must demonstrate unreasonable risk before restricting a substance, which is very different from REACH's precautionary pre-market model. TSCA applies to most industrial chemicals in the United States, except for products such as pesticides, foods, and drugs, and importers must file a TSCA import certification stating whether the chemical is on the TSCA Inventory or subject to a Significant New Use Rule (SNUR), Low Volume Exemption (LVE), or PFAS reporting under the new PFAS reporting window open April 13 to October 13, 2026. In 2024, EPA introduced major amendments that directly affect chemical importers, including stricter data requirements and faster review timelines.

UK REACH, K-REACH and Other Regional Schemes

A detailed side-by-side comparison of the four major frameworks — EU REACH, US TSCA, UK REACH, and Korea's K-REACH — covering registration triggers, SVHC obligations, SDS requirements, restricted substance controls, enforcement penalties, and key 2025–2026 changes shows that while the principles overlap, the practical requirements do not. UK REACH requires separate registration with the UK Health and Safety Executive (HSE) and a UK-based Only Representative, and EU REACH registrations are no longer valid in Great Britain, forcing dual registrations for companies selling into both markets. K-REACH in South Korea requires pre-registration and full registration for >1 tonne/year with annual reporting, plus unique requirements for existing versus new substances, while Turkey KKDIK, China IECSC/MEP, Japan CSCL, and Australia AICIS each have their own inventory and notification systems, creating a matrix of deadlines that importers must track.

Key Compliance Challenges for Importers

Registration and Data Sharing Costs

The first challenge is registration cost and data access, because for every product exported into the EU, suppliers are required to submit comprehensive safety data sheets (SDS) and chemical safety evaluations, and must join a Substance Information Exchange Forum (SIEF) or consortium to share toxicology studies. For SMEs importing 1–10 tonnes, the cost of a joint registration, lead registrant fees, and Chemical Safety Report can exceed the margin on the product itself, and non-compliance can result in severe fines and even restrictions on market access, making REACH compliance essential for global trade.

SVHC, Restrictions and PFAS Reporting

The second challenge is restricted and emerging substances, where REACH Annex XVII, Annex XIV authorisation list, Candidate List SVHC, and SCIP database for articles containing >0.1% SVHC intersect with global PFAS restrictions and POPs. Chemical regulations present complex compliance challenges, including EU REACH, PFAS restrictions, SDS, TSCA, and POPs, and companies must screen every import against all lists before customs clearance. In the US, TSCA requires importers to ensure that chemicals are not subject to Section 6 prohibitions, and in 2026, importers face additional PFAS reporting under TSCA Section 8(a)(7), which requires reporting of all PFAS manufactured or imported since 2011, creating a massive data gathering exercise across supply chains.

SDS, Labelling and Customs Documentation

REACH compliance requires Safety Data Sheets (SDS), product labelling, and poison centre notifications, and TSCA compliance requires importers and manufacturers to provide safety data and file certifications, yet SDS formats, language, and classification differ between EU CLP, US OSHA HazCom 2024 Rev 7, and other GHS adoptions. A US SDS that is compliant with OSHA may be rejected in the EU if it does not include EU-specific precautionary statements, exposure scenarios, and UFI code for poison centres, and vice versa, leading to cargo holds at the border. The solution is to maintain region-specific SDS, labels, and poison centre notifications, and to ensure that commercial invoice, packing list, Certificate of Analysis, Certificate of Origin, and Bill of Lading all carry consistent product identifiers, CAS numbers, and registration numbers, because customs officers now cross-check ECHA and EPA databases directly.

How Importers Can Build a Resilient Compliance System

The most successful bulk chemical importers treat compliance as a product qualification step, not as paperwork after purchase, by mapping each chemical to its CAS number, tonnage band, end-use, and destination market before ordering, and by appointing an Only Representative in EU/UK, a US agent for TSCA, and a local representative for K-REACH where needed. Building a central regulatory database that tracks registrations, expiry dates, tonnage updates, SVHC screening, and SDS versions, combined with quarterly checks of ECHA, EPA, HSE, and MoE updates, allows importers to anticipate sunset dates, restriction proposals, and PFAS bans before they affect supply. Investing in automated SDS authoring tools, SCIP dossier creation, and digital import certification helps reduce human error, while training procurement, logistics, and warehouse teams on GHS pictograms, transport classification under IMDG, and storage compatibility prevents incidents that trigger enforcement action.
