Evolving Standards in the Forestry Value Chain

As forest certification standards continue to evolve, the entire forestry value chain, from seedling to sawmill, is under increasing pressure to demonstrate transparency and sustainability. A recent talking point has been the FSC Pesticides Policy (FSC-POL-30-001 V3-0) and what it means for third-party timber processing plants, especially those involved in preservative treatment of poles and sawn timber.

At the centre of this discussion lies a simple but important question: “Are timber treatment chemicals used in pole plants and sawmills subject to FSC’s list of prohibited pesticides?”

Informing, Not Enforcing

Clause 4.12.12 of the FSC Pesticides Policy requires certified forest managers to: “Inform third-party processing plants … of the list of FSC prohibited chemical pesticides, encouraging them to avoid these pesticides in their processes … and request a list of such pesticides in use.”

This clause aims to extend sustainability beyond the forest boundary, encouraging awareness throughout the supply chain. However, it does not require forest managers to enforce pesticide restrictions on downstream partners. Their responsibility is to engage, inform and document, ensuring transparency as certified material moves through the value chain.

Processing Plants and the Pesticide Question

Processing facilities under the South African Wood Preservers Association (SAWPA) and the South African Utility Pole Association (SAUPA) have sought clarity on whether timber treatment substances such as creosote or copper chrome arsenate (CCA) fall under FSC’s definition of pesticides.

While some overlap may exist in chemical classification, FSC defines pesticides as substances used to control, destroy or repel pests during forest operations, not those used for post-harvest preservation or timber treatment.

Both SAWPA and SAUPA have confirmed that their member facilities comply fully with South African legal and environmental regulations, including SANS standards. As national chemical legislation continues to tighten, this compliance provides a strong foundation for responsible practice in timber treatment.

A Grey Area with Room for Collaboration

The link between FSC policy and timber treatment remains a grey area. While FSC’s Chain of Custody (CoC) standards do not regulate pressure treatment or restrict treatment compounds, the Pesticides Policy encourages voluntary avoidance of high-risk substances and clear communication throughout the chain.

Forest managers are therefore expected to share the FSC Prohibited Pesticides List and request information on chemicals used by their processing partners. This is not about enforcement; it is about transparency, due diligence and shared commitment to sustainability.

Strengthening the Chain Through Dialogue

This issue highlights the need for collaboration rather than compliance pressure. Forest managers play a leading role in initiating dialogue, while processing plants are encouraged to respond with openness and confidence, something both SAWPA and SAUPA members have demonstrated.

Their strong record of legal compliance and stewardship already meets the spirit of FSC’s policy, even where treatment chemicals fall outside its direct scope. This mutual understanding reinforces trust across the forestry supply chain and supports the Sector’s wider sustainability goals.

Final Thoughts

The treatment and preservation of timber, particularly utility poles and structural products, remains essential to the forestry sector. SAWPA and SAUPA member plants continue to operate with integrity, meeting national standards and upholding responsible chemical management.

Forest managers can fulfil their FSC obligations by simply engaging with these partners, sharing the relevant policies and documenting the exchange. In return, processors can demonstrate their own strong governance, ensuring that South Africa’s forestry value chain remains both credible and sustainable.

In a world of changing standards and growing expectations, collaboration remains the strongest preservative.
