Is Clean Harbors (CLH) stock Halal?

Clean Harbors is a leading provider of environmental and industrial services throughout North America. The company primarily focuses on hazardous waste management, offering a comprehensive range of services including the collection, transportation, treatment, recycling, and disposal of hazardous materials. Clean Harbors operates one of the largest networks of hazardous waste disposal facilities and service centers across the continent, emphasizing its commitment to environmental responsibility and sustainability. Before any of that matters to a Muslim investor, one question comes first: is Clean Harbors stock Halal?

Is Clean Harbors Shariah compliant?

Yes. In the October 2026 screening Clean Harbors (CLH) passes AAOIFI Shariah Standard No. 21: the business activity screen and every financial ratio screen hold. Industrial businesses like Clean Harbors usually pass the activity screen without drama. The harder test is financial: heavy assets mean heavy financing, and AAOIFI Shariah Standard No. 21 tolerates interest bearing debt and investments only below 30% of market capitalisation, ratios that shift with every move in the share price.

Does Clean Harbors pass the business activity test?

Yes. In the October 2026 screening Clean Harbors holds an overall PASS, which a stock only earns when its core business clears the activity screen. The activity itself raises no Shariah objection; the scrutiny belongs to the financing.

Is Clean Harbors' income Halal?

Yes, within AAOIFI's tolerance. Clean Harbors' income from non-permissible sources stays below 5% of revenue in the October 2026 screening, and the small impure portion is handled through purification: the factor of 99.79% tells holders of CLH what share of each dividend to keep and what remainder to donate to charity. On a dividend yield of around 0.30%, the purification amount is modest but real.

Does Clean Harbors meet AAOIFI's debt and investment ratio requirements?

Yes. Both caps hold this month: interest bearing investments and interest bearing debt each stay below 30% of market capitalisation, measured against a market capitalisation of $16.4B (market data as of 1 October 2026). Because the caps move with the share price, our Shariah Supervisory Board has CLH re-screened every month, and the result above always shows the latest verdict.

Why do other halal screeners show a different verdict for Clean Harbors?

Screeners can disagree without either being wrong. AAOIFI Shariah Standard No. 21, which Tabadulat applies, measures interest bearing debt and investments against market capitalisation with a 30% ceiling. MSCI and FTSE measure them against total assets with a 33% ceiling, and S&P and Dow Jones Islamic use a multi year average of market capitalisation. Data dates differ too, because each provider reads filings and prices on its own schedule. The same company can therefore pass one standard and fail another in the same month. Tabadulat publishes one answer, the AAOIFI result as of October 2026, and re-screens it every month.

Tabadulat is an ADGM regulated brokerage whose license covers Shari'a Compliant Regulated Activities, as the FSRA permission names them. New to the terminology? Gharar and Maysir, Sukuk, Zakat and purification are all explained in plain English.
