Globally Harmonized System (GHS) Compliance

Environmental & Chemical Regulations

Globally Harmonized System of Classification and Labelling of Chemicals

GHS Rev. 11 Is Published. OSHA Deadlines Are Here. Are Your SDSs and Labels Current Across Every Market You Ship To?

GHS compliance requires accurate chemical classification, standardized Safety Data Sheets, and compliant labeling—across 70+ countries, each adopting different GHS revisions and building blocks. OSHA's updated HazCom standard demands reclassification by mid-2026. The EU CLP continues adding new hazard classes.

Certivo automates GHS compliance from supplier SDS collection to multi-jurisdiction label and classification validation.

WhatisGHS?

The Globally Harmonized System is the UN's international standard for classifying chemical hazards and communicating them through standardized labels and Safety Data Sheets. For supply chain and compliance teams, GHS compliance means ensuring every chemical product shipped globally carries the correct classification, hazard pictograms, signal words, and a 16-section SDS aligned with the destination country's adopted GHS revision.

GHS Rev. 11 (September 2025) introduces a new atmospheric hazard class for substances contributing to global warming, refined criteria for chemicals under pressure, updated skin sensitization guidance using non-animal methods, and rationalized precautionary statements. Countries adopt these revisions on staggered timelines—OSHA aligns with Rev. 7/8, the EU CLP incorporates changes through Adaptations to Technical Progress, and Asian markets follow their own schedules.

GHS compliance requires chemical-level classification data—hazard categories, H-statements, P-statements, and pictogram assignments—validated against each target market's specific GHS implementation. When revisions are adopted or classification criteria change, your entire product portfolio requires reassessment.

GHS-SpecificPainPoints

The Building Block Nightmare

GHS is not one standard—it is 70+ national implementations, each adopting different revisions, different hazard classes, and different building blocks. The US omits environmental hazard sections. The EU adds unique hazard classes. Korea requires separate MoEL-specific data. One chemical product may need five different SDS versions and three different label formats to ship globally.

The Revision Reclassification Scramble

OSHA moves to Rev. 7/8. The EU adopts ATPs adding endocrine disruptors and PBT/vPvB classes. GHS Rev. 11 introduces atmospheric hazards. Each revision triggers reclassification of affected products—new H-statements, new pictograms, new precautionary language. Your SDS library of 5,000 products is now partially out of date. Finding which products are affected requires substance-level analysis across your entire portfolio.

The SDS Management Burden

Your company supplies 3,000 chemical products across 12 markets. Each market requires a localized, language-specific, revision-compliant SDS. Suppliers send you SDSs in inconsistent formats—some still labeled MSDS, some missing sections, some referencing deprecated classifications. Your EHS team spends 40% of their time on SDS management instead of risk reduction.

The Supplier SDS Quality Gap

A supplier sends an SDS for a raw material. Section 2 references an outdated classification. Section 3 lists incomplete concentration ranges. Section 14 transport data is missing. You discover this during a customer audit—not during incoming quality checks. Without automated SDS parsing and validation, non-compliant supplier data flows directly into your products.

FrequentlyAskedQuestions

Which companies must comply with GHS requirements?
Any company manufacturing, importing, distributing, or using hazardous chemicals must comply with GHS requirements in every market where they operate. In the US, OSHA's HazCom Standard applies to all employers with hazardous chemicals in the workplace. In the EU, the CLP Regulation applies to manufacturers and importers placing substances or mixtures on the market. Certivo maps your product portfolio against each jurisdiction's GHS implementation automatically.

What are the penalties for GHS non-compliance?
Penalties vary by jurisdiction. OSHA citations for HazCom violations are among the most frequently issued—with per-violation penalties exceeding $16,000 for serious violations and over $160,000 for willful or repeat violations (adjusted annually). EU CLP penalties are set by Member States and can include market withdrawal and fines. Non-compliant SDSs or labels can trigger shipment rejections, customs holds, and customer audit failures.

How does Certivo handle SDS compliance across multiple GHS revisions?
CORA parses every incoming supplier SDS and extracts classification data, hazard statements, and composition information. Certivo validates this data against the specific GHS revision adopted in each target market—OSHA HazCom (Rev. 7/8), EU CLP (with ATPs), WHMIS 2015, and others. When a jurisdiction updates its adopted revision, Certivo flags affected products for reclassification review.

Does Certivo support both SDS collection and SDS authoring workflows?
Certivo focuses on collecting, validating, and managing supplier SDSs as compliance evidence—ensuring every SDS in your library is current, complete, and jurisdiction-compliant. CORA extracts and validates SDS data at the section level, identifies gaps and outdated classifications, and generates audit-ready compliance reports. For SDS authoring, Certivo integrates with existing EHS authoring tools via API.

How does GHS compliance relate to REACH, RoHS, and other chemical regulations?
GHS classification data is foundational to broader chemical compliance. EU REACH requires SDSs to follow GHS format under Regulation (EU) 2020/878. RoHS substance restrictions intersect with GHS hazard classification for the same chemicals. TSCA reporting references GHS classification data. Certivo validates one supplier SDS submission against GHS, REACH, RoHS, and related frameworks simultaneously—eliminating duplicate collection campaigns.
