Titanium dioxide buyers have a new international testing reference. On October 16, 2026, the International Organization for Standardization published ISO 787-24:2026, covering photometric comparisons of pigment tinting strength and the relative scattering power of white pigments. For manufacturers using titanium dioxide (TiO₂, CAS 13463-67-7) in paints, plastics and coatings, the new edition provides a timely…

Choosing between ferrous sulfate and ferric salts for wastewater phosphorus removal requires more than comparing chemical prices or advertised iron content. The two types of iron compounds behave differently in treatment systems, and actual performance depends on wastewater chemistry, oxygen availability, dosing location and solids separation. For industrial procurement teams, the important question is not…

Chemical manufacturers using synthetic polymer microparticles in industrial processes may qualify for an exemption from the European Union's microplastics marketing ban and still have to report their estimated environmental releases. That distinction is becoming more important as the next reporting deadline approaches. By May 31, 2027, additional manufacturers, industrial downstream users and certain suppliers must…

The European Union's new packaging rules are already in effect, but not every requirement applies immediately—and chemical drums, intermediate bulk containers (IBCs) and flexible bulk bags need particular attention. Regulation (EU) 2025/40, known as the Packaging and Packaging Waste Regulation (PPWR), began applying on August 12, 2026. It introduces requirements covering packaging materials, conformity documentation,…

A chemical container reaches its labeled date, but its contents may not have suddenly become unusable. The real question is whether the material still meets its required specifications—and whether the date represents an expiration limit or a scheduled quality review. Understanding chemical shelf life helps manufacturers avoid unnecessary waste without compromising product performance, workplace safety,…

Type C and Type D bulk bags can both be designed for hazardous industrial environments, but they control static electricity differently. A Type C bag requires an effective grounding connection during filling and emptying. A properly qualified Type D bag uses specially designed static-protective material and does not require the bag itself to be grounded.…
