Procurement & Supplier Selection | Pain Point “Buy from whoever is cheapest”—this is often the most expensive sentence in colorant procurement. Behind low prices often hide hidden costs such as unstable batches, excessive addition, and absent after-sales. Calculated into mass production yield and rework, total cost may exceed that of a more stable supplier with […]

Compliance & Certification | Technical Application Children’s products are far more safety-sensitive than adult products. As the core of the EU Toy Safety Directive, EN71-3 limits the thresholds of migratable heavy metals in materials such as colorants, directly affecting children’s health. Many toy, stationery, and baby product companies fail on their first return shipment because […]

Compliance & Certification | Technical Application Is the color on food packaging safe? The answer is not in the word “waterborne,” but in food contact regulations. FDA (United States) and EC 1935/2004 (European Union) are the world’s two major food contact frameworks. They focus not on what the colorant “contains,” but on what it “migrates […]

Compliance & Certification | Technical Parameters “Low VOC” has become a standard selling point for coatings and colorants, but most users have only a vague concept of how VOC is actually measured, calculated, and what environmental labels really restrict. Different standards, sampling methods, and calculation bases can lead the same product to very different VOC […]

Compliance & Certification | Technical Application Industrial coatings and food packaging are the two colorant application scenarios with the greatest differences in compliance requirements: the former looks at China’s Ten-Ring Label and VOC limits, while the latter looks at FDA, EC 1935/2004, and other food contact regulations. The same colorant manufacturer must prepare two completely […]

Compliance & Certification | Technical Application Colorant export is never simply about “getting the goods there.” It is about “documents first, compliance first.” The EU market has three hard thresholds—REACH, RoHS, and EN71-3—while the United States has TSCA and Japan has CSCL. The absence of any one of these can lead to return shipments, notifications, […]

Over the course of a week, we moved from basic colorant concepts to coating color matching processes and construction implementation. There is a lot of information, but what is truly usable on site is often a table that can be quickly consulted. This article condenses the core points of Week One into a “Selection Quick […]

The most headache-inducing thing in color matching is not being unable to match accurately, but “there is always a little difference every time.” Where these color differences come from, how much is qualified, and how to manage them determine whether your delivery is stable. Starting from the core concept of ΔE, this article explains the […]
