I. EU Market: REACH is a Mandatory Threshold
For industrial adhesives exported to the EU, REACH compliance is a mandatory requirement for market access. REACH (EC 1907/2006) entails three levels of requirements: Registration—substances (or components of preparations) with an annual export volume exceeding 1 tonne must undergo REACH registration (completed by an EU-based importer or an Only Representative [OR] appointed by the exporter);
SVHC Testing—notification is required if the content of Substances of Very High Concern (SVHC)—such as heavy metals, phthalates, and polycyclic aromatic hydrocarbons; the SVHC list exceeds 240 items and is updated annually—exceeds 0.1%; Restricted Substances—prohibited substances (e.g., certain halogenated flame retardants) must not be detected. Supporting requirements include GHS classification and labeling (hazard communication—adhesives containing flammable solvents must be labeled with GHS pictograms, signal words, and hazard statements) and the SDS (Safety Data Sheet) covering 16 sections, including composition, hazards, first aid, and transport information.
Key implementation points: verifying report numbers on the issuing agency’s official website, re-testing upon annual list updates, and re-testing following composition changes—adhesives lacking a REACH report will be blocked during EU customs clearance.

Electronics and Food-Contact Applications: RoHS, UL, FDA/LFGB
Additional certifications are required based on specific application categories.
RoHS (EU Directive 2011/65/EU): Electronic adhesives (PCB potting compounds, conductive adhesives, encapsulants)—restricts 10 categories of hazardous substances, including lead, mercury, cadmium, and hexavalent chromium;
mandatory for adhesives exported as part of electronic products; test reports must accompany the shipment and include verification against the RoHS exemption list.
UL (USA): Electronic/Electrical Grade Adhesives—UL certification (e.g., UL 94 flammability ratings, UL 746C electrical performance) is a recognized market entry requirement for the US electronics sector and insurance companies; testing takes 4–8 weeks. Non-UL adhesives face restrictions when entering the US electronics supply chain.
FDA/LFGB (Food Contact): Food Packaging Laminating Adhesives (flexible packaging, paper cups, food bag lamination)—Compliance with FDA 21 CFR and German LFGB food contact standards (migration, sensory tests) is a mandatory procurement criterion in the food industry.
California Proposition 65 (Prop 65): California Market—Requires warning labels for hazardous substances such as lead and phthalates.
Application Matching: Use REACH+RoHS+UL for electronic adhesives and FDA/LFGB for food packaging adhesives—do not attempt to substitute application-specific certifications with general ones.
III.
Hazardous Goods Transport Certification: Mandatory for Solvent-Based Adhesives
A specific hurdle for adhesive exports is the transport of hazardous goods.
Classification Criteria: Adhesives with a flash point below 60°C (e.g., solvent-based adhesives containing acetone or toluene) are classified as hazardous goods—requiring UN numbers (common examples include UN 1133 for adhesives and UN 1866 for resin solutions), hazard classes (primarily Class 3 flammable liquids), and packing groups (I, II, or III).
Compliance Requirements: Hazardous goods classification and identification report (issued by a professional agency); UN-certified packaging (Packing Group II or III, such as 25kg tight-head steel or plastic drums); hazardous goods declaration (IMDG Code for sea freight, IATA DGR for air freight); and a Dangerous Goods Packaging Certificate (certifying packaging performance).
Cost Impact: Sea freight costs for hazardous goods are 30%–50% higher than for general cargo; Full Container Load (FCL) shipping is preferred to reduce per-ton costs. Some ports limit hazardous goods capacity, so booking space in advance is essential.
Special Note: Water-based (solvent-free) adhesives are usually transported as general cargo—choosing water-based formulations avoids hazardous goods requirements, offering an effective way to reduce export costs.
IV. Standardized Systems and Supporting Documentation
Management systems and documentation form the foundation for exports.
ISO 9001 (Quality Management System): A baseline requirement for B2B factory audits and order placement; the system ensures batch consistency (viscosity, cure time) for adhesives, and most overseas clients require the corresponding certificate.
IATF 16949 (Automotive): Essential for supplying adhesives (structural body adhesives, interior adhesives) to the automotive supply chain.
ISO 14001 (Environmental Management System): Preferred by European and American clients.
Supporting documentation checklist: Test reports (REACH/RoHS/UL/FDA), SDS (multilingual, prioritizing the destination country’s language), TDS/Technical Data Sheets (viscosity, curing, temperature resistance, shear strength), Certificate of Origin (CO), packing lists and invoices, and batch numbers with certificates of conformity.
Export documents serve as the “entry ticket” for customs clearance—verify report numbers, ensure documents align with specific batches, and maintain a robust documentation system to ensure smooth adhesive exports.

Practical Certification Steps and Factory Selection Advice
Six practical recommendations for certification: 1. Align with markets: EU (REACH + RoHS), USA (UL + FDA + California Prop 65), Food Contact (LFGB)—tailor the combination to the destination market and product category;
avoid both over-certification and missing necessary certifications. 2. Verify agencies: Check report numbers on the official websites of SGS, Intertek, or TÜV, and ensure the report holder matches the supplier.
3. Manage validity periods: Annual updates for REACH lists, annual renewals for OEKO-TEX, and annual UL audits—an expired report is equivalent to having no report at all.
4. Address hazardous goods early: For solvent-based products, obtain classification assessments and dangerous goods packaging certificates in advance, and include transport costs in quotations.
5. Select factories based on certification portfolios: Choose industry leaders with comprehensive certifications (e.g., Huitian, Guibao, Kangda—possessing complete REACH/RoHS/UL/FDA systems) and exercise caution with smaller factories that lack full certification coverage.
6. Incorporate responsibilities into contracts: Suppliers must guarantee the authenticity of certifications, and the allocation of liability for losses due to customs seizures must be explicitly stated in the contract.
Establishing a comprehensive certification system for adhesives is akin to securing a “passport” to the target market—export certification is not merely a cost, but an investment in market access.
Conclusion
Which export certifications are required for industrial adhesives?
EU REACH and RoHS; US UL, FDA, and California Proposition 65;
LFGB for food contact; IMDG/UN for dangerous goods transport; and ISO 9001/IATF 16949 management systems—these should be selected and combined based on the specific market and product category.
By ensuring proper agency verification, managing validity periods, addressing dangerous goods requirements in advance, and incorporating responsibilities into contracts, manufacturers can ensure smooth customs clearance and secure market access for their adhesives.
