Identifying Regulated Chemicals in Annex III

Review the Annex III Chemical List

Start by confirming whether your chemical is included in the Annex III list at pic.int. This list outlines all substances regulated under the Prior Informed Consent (PIC) procedure. Annex III is divided into three categories: Pesticides, Industrial Chemicals, and Severely Hazardous Pesticide Formulations.

Check the chemical's CAS number against the Annex III database. Once confirmed, download the Decision Guidance Document (DGD) linked to the chemical.

"For each chemical listed in Annex III of the Rotterdam Convention, a decision guidance document (DGD) is prepared... The DGDs are intended to help governments assess the risks connected with the handling and use of the chemical and to make more informed decisions about its future import and use".

The DGD provides critical details, including the chemical's properties, hazard classifications, and the reasoning behind its regulation. Be sure to review the document thoroughly, as some listings might only apply to specific formulations or industrial uses. Also, keep an eye on periodic updates to the Annex III list.

Check for Recent Updates

The Annex III list is updated regularly as new chemicals are added based on recommendations from the Chemical Review Committee (CRC) and decisions made during the Conference of the Parties (COP). The Secretariat publishes a PIC Circular twice a year - in June and December - highlighting updates to Annex III and summarizing import responses from participating countries.

Make it a habit to check pic.int for updates. When a chemical is newly added, a fresh DGD is created and distributed to all Parties. Additionally, verify the import statuses of destination countries using the Import Response database. This step is crucial to avoid customs issues or legal penalties tied to non-compliance.

Staying informed about chemical listings and updates is a key part of securing prior informed consent and ensuring proper labeling and documentation practices.

Submit Notifications of Final Regulatory Actions

When your country bans or heavily restricts a chemical for health or environmental concerns, your Designated National Authority (DNA) must notify the Rotterdam Convention Secretariat in writing within 90 days of the final regulatory action taking effect. According to the Rotterdam Convention Secretariat:

"Each Party that has adopted a final regulatory action shall notify the Secretariat in writing of such action."

To do this, you need to complete the official "Form for Notification of Final Regulatory Action." This form should include details like the chemical's CAS number, trade names, specifics of the regulatory action, and a summary of the associated risks. The Secretariat will review your submission within six months. Once validated, the notification will appear in the PIC Circular, which is distributed to all Parties every June and December.

Secure Import Responses

Before exporting any chemical listed in Annex III, check the import response from the destination country. Each Party must provide an import response for every Annex III chemical, indicating one of three options: Consent, No Consent, or Consent under conditions. To find this information, visit the Import Responses Database at pic.int or review the most recent PIC Circular. If the response is "Consent under conditions", make sure you understand and comply with those conditions before proceeding. If no response is available, contact your DNA to determine whether explicit consent is required or if interim rules apply.

"For each chemical listed in Annex III of the Convention and subject to the PIC procedure, all Parties are required to take a decision on whether or not they will allow future import of the chemical." - Rotterdam Convention Secretariat

Avoid Exports to Countries with Import Bans

Never export an Annex III chemical to a country that has issued a "No Consent" response. It is the exporter’s responsibility to ensure that shipments align with the importing Party's decision.

"The exporting Party must ensure that exports do not occur contrary to the import decision of the importing Party." - Rotterdam Convention Secretariat

Additionally, if a chemical is banned or severely restricted in your own country but is not yet listed in Annex III, you must send an Export Notification to the importing country before the first export of the year. Make sure you have up-to-date contact information for the importing country's DNA to ensure the notification reaches the correct official. Also, verify that your labeling and documentation meet the requirements outlined in the PIC procedures.

Meeting Labeling and Documentation Requirements

Once you've validated import responses, it’s crucial to ensure your product labeling and documentation meet the necessary standards. Proper labeling and thorough documentation not only satisfy legal requirements but also help communicate potential risks throughout the supply chain.

Hazard Labeling and Packaging Standards

For every Annex III chemical, labels must clearly convey risks. The Rotterdam Convention mandates that labels adhere to international standards. Article 13, Paragraph 3 of the Convention specifies:

"Each Party shall require that chemicals listed in Annex III and chemicals banned or severely restricted in its territory are, when exported, subject to labelling requirements that ensure adequate availability of information with regard to risks and/or hazards to human health or the environment, taking into account relevant international standards."

To comply, use the Globally Harmonized System (GHS) for labeling. This includes hazard pictograms, signal words like DANGER or WARNING, hazard (H) statements, and precautionary (P) statements. Labels should align with Section 2.2 of the accompanying Safety Data Sheet (SDS). Additionally, shipping documents must include the correct Harmonized System (HS) customs code, as assigned by the World Customs Organization, to help customs officials quickly identify regulated chemicals.

Include Safety Data Sheets (SDS)

Clear labeling should always be paired with accurate, up-to-date Safety Data Sheets (SDS). Provide an SDS for each Annex III chemical or any chemical banned or heavily restricted in your country. The SDS must follow an internationally recognized 16-section format for workplace chemicals. The Convention highlights:

"The information on the label and on the safety data sheet should, as far as practicable, be in one or more of the official languages of the importing Party."

Translate the SDS into the official language of the importing country to avoid customs delays and ensure proper handling. If the chemical is registered under REACH and exceeds 10 tonnes per year, you may also need to supply an extended SDS (eSDS) with exposure scenarios attached. Check that Section 14 of your SDS matches the transport labels on your packaging, ensuring hazard diamonds and UN numbers are consistent.

Maintain Accurate Records

Keep detailed records of all Prior Informed Consent (PIC) decisions, export notifications for non-Annex III chemicals, and communications with trade partners. If an importing Party doesn’t confirm receipt within 30 days, send a second notification and document this step. Retain all SDSs, labels, shipping documents, and HS codes for compliance audits. These record-keeping requirements remain in effect until a chemical is formally added to Annex III and the importing Party’s response is distributed by the Secretariat.

Monitoring Updates and Staying Informed

Staying compliant with the Rotterdam Convention isn’t a one-time task - it’s an ongoing process. As the Convention updates its chemical reviews and import responses, keeping up-to-date is essential to avoid potential trade issues.

Follow Chemical Review Committee Recommendations

Chemical Review Committee

The Chemical Review Committee (CRC) plays a vital role in the Convention. This group of 31 government-appointed experts evaluates notifications about banned or severely restricted chemicals and advises the Conference of the Parties (COP) on which chemicals should be added to Annex III. According to the Rotterdam Convention Secretariat:

"The Chemical Review Committee (CRC) is a subsidiary body of the Rotterdam Convention... its main function is reviewing notifications and proposals from Parties and make recommendations to the Conference of the Parties on the listing of chemicals in Annex III."

Chemicals flagged by the CRC are often high-risk candidates for future trade restrictions. To stay ahead, regularly check the Database of Notifications of Final Regulatory Actions (FRA) for updates on chemicals restricted by individual countries - these often signal the next additions to Annex III. Once a chemical is listed in Annex III, download its Decision Guidance Document (DGD) for technical details and the reasoning behind its inclusion. Reviewing CRC recommendations and COP reports regularly ensures you’re prepared for upcoming regulatory changes.

Track Conference of the Parties (COP) Decisions

The Conference of the Parties (COP) finalizes decisions on Annex III updates and compliance obligations. After each COP meeting, it’s crucial to review the official "Reports and Decisions" page to identify new legal requirements and effective dates for Annex III amendments. These decisions build on CRC recommendations, making them key to understanding your compliance responsibilities.

Another essential resource is the PIC Circular. Published twice a year, this document provides updates on import responses and regulatory changes. The Rotterdam Convention Secretariat highlights its importance:

"The PIC Circular is a key document in the implementation of the Rotterdam Convention... It is published every six months, in June and December."

Make it a habit to review the PIC Circular in June and December. This ensures you’re aware of the latest import responses and regulatory actions, as countries can update their consent decisions at any time.

Source Frequency Key Information Provided
PIC Circular Every 6 Months (June/Dec) Import responses, new notifications of regulatory action, and proposals for hazardous formulations.
COP Reports Periodic (Post-Meeting) Final decisions on Annex III listings and amendments to Convention procedures.
FRA Database Ongoing/Real-time National-level regulatory actions that may lead to future global listings.
DGDs Per Chemical Listing Technical details, health/environmental risks, and guidance for Annex III chemicals.
