Exporting silica sand from Morocco to Australia requires four workstreams to be handled together: technical lot qualification, workplace hazard communication, customs classification and biosecurity. A correct product data sheet alone is therefore not enough.
For a Moroccan supplier, the best starting point is to have the dossier reviewed by the Australian importer before shipment. In Australia, the importer has its own duties when introducing a hazardous chemical into the market or a workplace. The importer must also self-assess the tariff classification of imported goods and check the biosecurity conditions that apply to the specific case [1–2,6–9].
Key takeaway: a good shipment is not only a conforming lot. It is a conforming lot supported by an adapted SDS, a coherent customs classification and a verified biosecurity dossier.
1. First question: is the product a hazardous chemical in Australia?
Australia uses the Globally Harmonized System, 7th revised edition - GHS 7 for classification and labelling of hazardous chemicals. Since 1 January 2023, manufacturers and importers must use GHS 7 for newly imported or manufactured hazardous chemicals [2].
This does not mean that a natural sand must be classified automatically solely because it contains quartz.
Classification should address the actual product placed on the market, taking into account its composition, physical form, available data and applicable criteria. For silica sand, useful information can include:
- bulk SiO₂ content;
- mineralogy and presence of crystalline quartz;
- fine fraction and dust-generation potential;
- particle-size distribution;
- the customer’s process;
- operations capable of generating a respirable fraction, such as crushing, grinding, cutting or other mechanical treatment.
Safe Work Australia notes that respirable crystalline silica can be generated when silica-containing materials are mechanically processed [3].
For the buyer, the message is therefore more precise than “quartz = hazardous”: bulk composition, GHS classification and actual workplace exposure need to be separated.
2. An overseas SDS is not automatically an Australian SDS
For a product classified as hazardous, the Australian importer must prepare or arrange a Safety Data Sheet - SDS that complies with the applicable WHS rules [1].
Safe Work Australia highlights several important requirements:
- the SDS must be in English;
- it must use Australian legal units of measurement;
- it must state the date of preparation or last review;
- it must identify the Australian manufacturer or importer, with an Australian address and business phone number;
- it must remain accurate and current;
- it must be reviewed at least once every five years.
An SDS prepared in Morocco, the European Union or the United States can be a useful starting point, but the Australian importer must check that it complies with GHS 7 and Australian WHS requirements [1–2].
The same logic applies to the label of a hazardous product: an overseas label may omit locally required information such as the Australian importer’s contact details.
What the Moroccan supplier should provide
To support that review, the supplier should provide at least:
- commercial identity and precise product description;
- chemical composition;
- available mineralogy;
- particle-size distribution;
- moisture;
- fines data;
- existing SDS;
- lot certificate of analysis;
- test methods used;
- intended industrial use when known.
The purpose is not to ask the Moroccan supplier to make the Australian importer’s legal decision, but to give the importer the data needed to make it correctly.
3. Respirable crystalline silica: read the Australian value as an exposure limit
As of 27 September 2026, Safe Work Australia lists a Workplace Exposure Standard for respirable crystalline silica - RCS of 0.05 mg/m³ over eight hours, TWA [3].
This figure is a workplace airborne concentration. It is not:
- a silica-sand purity specification;
- a maximum quartz content in the product;
- an acceptance threshold for a certificate of analysis;
- a bulk SiO₂ limit.
Mixing those concepts would create the wrong supplier specification.
A terminology change starts on 1 December 2026
Australia is moving from Workplace Exposure Standards - WES to Workplace Exposure Limits - WEL on 1 December 2026 [4].
Safe Work Australia stated in June 2026 that proposed levels for nine substances, including RCS, would not be changed in that transition. The RCS level therefore remains unchanged when WES terminology becomes WEL [5].
A dossier prepared in late 2026 should therefore be dated and contextual: it can state the current WES while noting the imminent regulatory transition.
4. The certificate of analysis and SDS answer different questions
A Certificate of Analysis - CoA documents whether a lot conforms to an agreed commercial specification.
An SDS communicates hazards, preventive measures and information needed for safe use of a hazardous product.
The documents complement one another.
| Document | Main question |
|---|---|
| CoA | Does this lot meet the agreed technical specification? |
| SDS | What hazards and preventive measures must be communicated? |
| Technical data sheet | Which properties and uses does the supplier describe? |
| Particle-size report | Is the size distribution suitable for the application? |
| Mineralogical report | Which mineral phases are present? |
| Packing / shipping documents | Does the shipped lot match the declared goods? |
For an industrial lot, the CoA should clearly identify the lot number, date, test methods and units.
XRF can document bulk chemistry; XRD can add mineralogical information when mineral phases matter. These methods answer different questions. See our guide to XRF and XRD analysis of silica sand.
5. Australian customs: 2505.10.00 for natural silica sands
The Australian Border Force Working Tariff classifies silica sands and quartz sands under 2505.10.00, currently showing a Free rate [6].
That line concerns natural sands.
The same chapter distinguishes:
- 2505.10.00: silica sands and quartz sands;
- 2506.10.00: quartz other than natural sands;
- 2506.20.00: quartzite.
All three currently show a Free rate, but the similar duty rate does not make classification optional. The declaration must match the actual nature and presentation of the goods [6].
A natural sand that has been washed and size-classified is not necessarily the same tariff product as crushed quartz or a powder subjected to different processing.
ABF reminds importers that they must self-assess the correct tariff classification and that penalties can apply for incorrect or misleading information [6–7].
6. “Free” does not mean “zero import cost”
The Free duty rate shown for 2505.10.00 does not mean that the transaction has no tax or clearance costs.
Australia generally applies 10% GST to the Value of the Taxable Importation - VoTI, which includes the customs value, relevant international transport and insurance to the place of consignment in Australia, and any customs duty payable [8].
Import declarations can also attract Import Processing Charges and biosecurity charges depending on the declaration and logistics channel.
For goods valued above AUD 1,000, an Import Declaration is generally required [7].
A Moroccan supplier should therefore not present a Free tariff line as a promise of zero landed cost. Final cost depends on the import scenario.
7. Biosecurity: check BICON before shipment, not after arrival
Australia has a highly structured biosecurity system.
The Department of Agriculture, Fisheries and Forestry identifies BICON - Biosecurity Import Conditions system as the tool used to determine whether a commodity:
- is permitted;
- is subject to conditions;
- requires supporting documentation;
- requires treatment;
- requires an import permit [9].
For industrial silica sand, it would be unsafe to state that a permit is always required or never required. The exact case should be checked against the product, its preparation, intended use and origin.
Container cleanliness is part of the dossier
DAFF also places strong emphasis on sea-container hygiene.
Before loading, contamination should be avoided from:
- soil;
- seeds;
- insects;
- snails;
- plant or animal material.
The department states that a cleanliness declaration is required for imported containers and that a packing declaration should document container cleanliness and whether straw or timber packing materials were used [10].
For a mineral product shipped in bulk or big bags, this logistics layer matters: a chemically compliant product can still be delayed if the container or packaging introduces a biosecurity risk.
8. What supplier dossier should be sent before the first container?
A practical dossier can be structured into five blocks.
A. Product identity
- commercial name;
- precise physical description;
- form: natural sand, crushed quartz, powder or other;
- intended use;
- country of origin.
B. Technical data
- SiO₂ and relevant oxides;
- mineralogy where needed;
- particle-size distribution;
- moisture;
- fines;
- net mass;
- sampling method;
- analytical method.
C. Hazard communication
- current SDS;
- available classification;
- data needed for GHS 7 review;
- crystalline-quartz information;
- dust-control recommendations.
D. Customs and logistics
- proposed tariff code;
- commercial invoice;
- packing list;
- agreed Incoterm;
- net / gross weight;
- number of bags or big bags;
- Bill of Lading or transport document;
- consignor and consignee details.
E. Biosecurity
- importer BICON check result;
- required documents or permits where applicable;
- packing declaration;
- container cleanliness documentation;
- any required treatment.
This structure helps the importer avoid mixing raw-material qualification, WHS, customs and biosecurity into one vague “compliance” task.
9. Which controls are actually useful to an Australian buyer?
The answer depends on the final application. Sand for glass, foundry, filtration or mortar does not use the same purchasing specification.
An import dossier should therefore not invent a universal “Australian silica-sand specification”.
A buyer should instead define:
- final use;
- critical parameters;
- test methods;
- lot tolerances;
- control frequency;
- acceptance or rejection rules;
- documents required with each shipment.
Where particle size is critical, values such as D10, D50 or D90 can be useful, but only when the measurement method and comparison basis are consistent.
10. A seven-step qualification procedure
For a first Morocco → Australia supply relationship, a robust sequence is:
- define the application and raw-material requirement;
- qualify a representative sample;
- validate several lots, not one exceptional sample;
- have the classification, SDS and label reviewed by the Australian importer;
- confirm customs classification and the tax scenario;
- check BICON and container preparation;
- authorise commercial shipment only after the documentation is aligned.
Sampling representativeness remains fundamental. A strong analysis on a few hundred grams does not guarantee the conformity of an industrial shipment if the sampling plan is weak.
11. Four mistakes to avoid
Copying an EU SDS without adaptation
GHS principles are related, but Australia has its own requirements, including local importer identification.
Presenting 0.05 mg/m³ as a quartz-content limit
It is a workplace airborne exposure value, not a maximum silica content in the product.
Using 2505.10.00 for every “silica-rich” product
Classification depends on the actual form of the goods. The Working Tariff distinguishes natural sand, quartz and quartzite.
Ignoring the container because the product is mineral
Australian biosecurity controls can also focus on contamination of containers, packaging and cargo.
Conclusion
The most reliable way to export silica sand from Morocco to Australia is to build a coordinated supplier-importer dossier.
The supplier documents the lot, particle size, moisture, chemistry and mineralogy. The Australian importer reviews GHS 7 classification, adapts the SDS and label where required, confirms tariff classification and checks BICON conditions.
The Working Tariff currently classifies natural silica sands under 2505.10.00 - Free, but GST, processing charges and biosecurity remain separate. Likewise, the 0.05 mg/m³ RCS value must remain clearly identified as an occupational exposure limit, not a product specification.
