CLP

CLP is EU Regulation (EC) No 1272/2008, the European Union implementation of the Globally Harmonized System for chemical classification, labelling, and packaging. CLP is mandatory for all substances and mixtures placed on the EU and EEA market. The regulation came into force in 2009 with phased deadlines for substances (2010) and mixtures (2015), and now governs every label, every SDS, and every packaging compliance check for chemicals shipped into the EU.

What CLP requires

Three things CLP makes the supplier do:

1. Classify every substance and mixture against CLP hazard criteria (which mirror GHS)
2. Label every package with the correct CLP elements: hazard pictograms, signal word, hazard statements (H-codes), precautionary statements (P-codes), product identifier, supplier identification, and (for mixtures) any nominal contents
3. Package chemicals so they cannot leak, are child-resistant where the hazard requires (PG I substances and certain consumer products), and are tactile-warning where required for visually impaired users

For a Chinese chemical exporter shipping into the EU, CLP compliance is on the EU importer (the EU-based “downstream user” or distributor). But the upstream supplier must provide accurate classification data and a CLP-compliant SDS for the EU importer to use. A factory that supplies an SDS classified only against China GB/T 17519 forces the EU importer to re-classify against CLP, a non-trivial cost.

Self-classification vs harmonised classification

CLP allows two paths:

• Self-classification. The supplier classifies based on available data per CLP criteria. This is the default for most substances.
• Harmonised classification. For some substances, ECHA has published a binding harmonised classification in CLP Annex VI. Suppliers must use the harmonised classification for those substances (deviation is allowed only to make it stricter).

About 4,500 substances have harmonised classifications. The list grows by 30 to 80 substances per annual ATP (Adaptation to Technical Progress) cycle. For a Chinese factory exporting a substance with harmonised classification, the EU importer expects the SDS to use the harmonised entry, not a self-classification that differs from it.

The harmonised list disproportionately covers carcinogens, mutagens, reproductive toxicants (CMRs), severe sensitisers, and a growing list of endocrine-disrupting substances. Most industrial commodity chemicals are self-classified.

CLP and REACH

CLP and REACH are siblings, both administered by ECHA, both addressing chemical management in the EU. The split:

• REACH is registration, evaluation, authorisation, and restriction of chemicals, the substance-management regime. Anyone supplying a substance to the EU above 1 tonne per year must register it with ECHA.
• CLP is classification, labelling, and packaging, the hazard-communication regime. Every chemical on the EU market must be labelled per CLP regardless of REACH registration status.

The two work together. The REACH registration dossier feeds the CLP classification (and vice versa). The substance’s REACH registration number sometimes appears on the CLP label.

SVHC overlay

CLP does not directly create the SVHC (Substances of Very High Concern) framework, that sits under REACH Article 57. But CLP classification feeds SVHC identification. Substances classified as Category 1A or 1B carcinogens, mutagens, reproductive toxicants, or persistent bioaccumulative toxic (PBT) substances under CLP become candidates for SVHC listing under REACH.

For a Chinese factory exporting a CMR-classified substance to the EU, the path from CLP classification to SVHC listing to authorisation requirement is a real risk on the 5- to 10-year horizon. Substances on the SVHC candidate list (currently about 240 entries) trigger downstream-user notification obligations and may move to the REACH Authorisation List, requiring EU customers to obtain authorisation to continue using the substance.

Practical CLP compliance for Chinese exports

For an EU-bound shipment from China:

1. Confirm CLP-compliant SDS in EU language(s) for the destination
2. Confirm the package label carries the CLP elements in EU language(s), pictograms, signal word, H-codes, P-codes, product identifier, supplier name and address (the EU-side supplier)
3. For substances with harmonised classification, confirm the SDS uses the Annex VI entry
4. Cross-check the substance against the SVHC candidate list, if listed, the EU importer must notify downstream users
5. Cross-check the substance against the REACH Authorisation List (Annex XIV), if listed, the EU customer needs authorisation to use it after the sunset date

The upstream Chinese factory’s role is providing the data and the SDS shell. The downstream EU importer’s role is verifying CLP compliance at the point of placing the substance on the EU market.

Operator note: the language coverage trap

CLP requires labels and SDSs in the official language(s) of every EU country where the substance is sold. The EU has 24 official languages. A label only in English passes for some countries (Ireland, Malta) but not for others (Germany, France, Italy, Spain, Poland). For a multi-country EU distribution, the label may need to carry 4 to 6 languages.

A Chinese factory printing labels in English-only loses the buyer the ability to distribute in those EU countries without re-labelling at the EU warehouse, a significant added cost. Specify the required label languages on the PO before printing.
