    Key Areas Monitored EU REACH SVHC Candidate List, US EPA TSCA
    Major Same-Day Changes None (no same-day additions or emergency revisions to lists/rules detected)
    Overall Risk Level Low–Medium (baseline compliance obligations remain in force; recent key deadlines have passed or are approaching)

    Note: No major same-day changes to EU REACH SVHC or US EPA TSCA were detected on the review date, so this is a daily monitoring report. However, several critical compliance milestones in July–August 2026 have taken effect or are approaching, requiring immediate attention from exporters.

    2. EU REACH SVHC (Key Focus)

    • Current status: The Candidate List contains 253 entries. The latest update (2026-02-04) added n-hexane (CAS 110-54-3) and 4,4′-[2,2,2-trifluoro-1-(trifluoromethyl)ethylidene]diphenol and its salts (BPAF, Bisphenol AF).
    • Key deadline: For articles containing a newly listed SVHC above 0.1% (w/w), manufacturers/importers must notify ECHA within six months of inclusion (i.e., by 2026-08-04) under REACH Art. 7(2); SCIP database notification under the Waste Framework Directive also applies.
    • Risk alert: The notification deadline (Aug 4) has passed. Exporters to the EU who have not yet notified are in a state of non-compliance, facing Member State enforcement, product recalls, and market exclusion.

    Recommended Actions:

    1. Immediately screen the supply chain to confirm whether articles contain n-hexane / BPAF (focus: fluoroelastomer seals/O-rings, cleaning agents, coatings, cross-linking agents).
    2. For articles above 0.1% with annual volume above 1 tonne, submit the overdue ECHA notification promptly and complete the SCIP notification in parallel.
    3. Establish a semi-annual SVHC review mechanism (ECHA typically updates the list every six months; a new update is expected in H2 2026).
    4. For fluoroelastomer parts containing BPAF, assess the future risk of inclusion in the Authorisation List (Annex XIV) and identify substitute materials early.

    3. US EPA TSCA (Key Focus)

    • 2026-07-23 (Final Rule): EPA extended compliance dates for the perchloroethylene (PCE) and carbon tetrachloride (CTC) risk management rules without weakening substantive protections.
    • 2026-04 (Final Rule): The TSCA section 8(a)(7) PFAS reporting start date was delayed to 2027-01-31 (or 60 days after the revised final rule takes effect, whichever is earlier), giving entities that manufactured/imported PFAS in 2011–2022 more preparation time.
    • 2026-05-22 (Final Rule): The TSCA 8(d) health and safety data reporting deadline was extended to 2027-05-21.

    Risk Level: Low–Medium (mostly extensions and proposals, not immediate bans).

    Recommended Actions:

    1. PFAS-related entities: use the extended window to compile 2011–2022 PFAS manufacture/import data and prepare reporting materials.
    2. Exporters of the 14 SNUR-proposed substances: assess whether products fall under a “significant new use” and submit comments during the comment period if needed.
    3. Continuously track PMN/SNUR final rules and build an internal 90-day advance-notification workflow.

    4. China GB Standards (Baseline)

    • 2026-07-30: 15 mandatory national standards released (incl. GB 7916-2026 Cosmetics Safety General Requirements).
    • 2026-05-25: Two mandatory PV standards (Safety Requirements for PV Modules; Nameplate Marking Requirements for PV Modules) released, effective 2027-06-01.
    • 2026-08-01: GB 46520-2025 Safety Specifications for Burning Behaviour of Thermal Insulation Materials implemented.
    • No same-day additions.

    5. Overall Action Plan (by priority)

    1. Priority 1 (Urgent): Screen supply chains and complete overdue EU REACH SVHC notifications (n-hexane / BPAF).
    2. Priority 2 (Monitor): Track the 14-chemical TSCA SNUR proposal comment process and PFAS reporting preparation.
    3. Priority 3 (Baseline): Monitor GB mandatory standard effective dates and align domestic production accordingly.
