How to approve chemical labels and packaging
Approve the formulation and hazard classification before signing off artwork. Match the pictograms, statements and supplier details to that assessment, then check the actual container and any required child-resistant closure or tactile warning. Factory checks in China can be coordinated by Cambridge China Bridge.
Start with the mixture you will actually import
Ask for the formulation, current SDS, intended uses and a written classification assessment for the exact adhesive, paint or cleaning mixture. Identify the formulation revision and intended customers. Ask a chemical specialist to resolve missing information or conflicting classifications before you approve printing.
Keep registration and disinfectant claims on a separate review track using our cleaning products guide. This approval file should connect the agreed mixture to its label, container and closure, rather than repeat that wider chemical-regime assessment.
Check the complete label, not just the symbols
For a hazardous mixture in packaging, the required label elements include supplier name, address and telephone number, product identifiers, and applicable pictograms, signal words, hazard statements, precautionary statements and supplemental information. For packs made available to the general public, nominal quantity is required unless shown elsewhere on the package.
Request English artwork and check your importer contact details directly. Compare the product identity with the SDS and agreed specification. Ask the reviewer to confirm any ingredient-specific supplemental wording; a familiar brand name or a generic warning panel is not a useful approval basis.
Match pictograms and wording to the classification
GB CLP pictograms are diamond-shaped with a red border and white background. Hazard statements describe the hazard and follow the classification criteria. Precautionary statements describe measures to reduce or prevent harm. Check the applicable signal word, Danger or Warning, alongside the selected statements.
Approve a physical printed sample on the intended container. Check that curvature, seams, overlabels and the closure do not obscure the information. Compare every statement with the reviewed wording rather than accepting a factory translation. Our packaging sourcing guide helps with print specifications and sample matching.
Decide safety features before choosing the pack
Child-resistant closures and tactile warnings have separate triggers. HSE explains that classification or specified substances at specified concentrations can trigger these features. For general-public supply, skin corrosion is among the classifications requiring a child-resistant fastening, while respiratory sensitisation is among those requiring a tactile warning. These examples are not the complete trigger lists.
Ask the reviewer to record whether each feature applies, including any relevant exception, against the current GB CLP packaging provisions. Then obtain evidence for the proposed container, closure and tactile feature. Match report identifiers to the actual components using our test-report verification guide; do not approve a cap merely because it is described as child-resistant.
Release production against an agreed approval file
HSE says hazardous-chemical packaging should prevent escape, resist adverse effects from the contents and withstand normal handling. A replaceable closure must continue preventing escape after repeated use. Ask for compatibility and leakage evidence for the agreed mixture and complete pack, then inspect filled samples for leakage, deterioration and closure operation.
Keep the classification assessment, reviewed artwork, component specifications, supporting reports and signed sample together. Give the factory written instructions to stop for review if the formulation, bottle, cap or artwork changes. Cambridge China Bridge’s staff in China can compare production with the approved sample; retain the chemical assessment in your importer compliance file.
Frequently asked questions
Can I approve a chemical label from the SDS alone?
Use the SDS as a cross-check, alongside the exact formulation, classification assessment, artwork and packaging evidence. Resolve mismatches before approving printing.
Whose contact details go on a hazard label?
The required elements include the supplier’s name, address and telephone number. For your import approval, check your importer details directly rather than copying the factory’s panel.
Do all cleaning products need child-resistant caps?
No. The requirement depends on the relevant classification or substance-concentration trigger and supply conditions. Ask for a written applicability decision for the exact mixture and pack.
Is a printed triangle a tactile warning?
A tactile warning is a raised-profile warning. Ask for evidence for the proposed physical feature and check the production sample by touch; flat printed artwork does not provide that feature.
