As an accredited J-Acid factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | The packaging for J-Acid consists of a 25 kg fiber drum with an inner polyethylene liner, clearly labeled with product details. |
| Shipping | J-Acid should be shipped in tightly sealed, labeled containers made of compatible materials, such as plastic or metal, to prevent leaks or contamination. Transport must comply with relevant local, national, and international regulations for hazardous chemicals. Protect from direct sunlight, moisture, and extreme temperatures during transit. Handle with proper safety precautions. |
| Storage | J-Acid should be stored in a cool, dry, and well-ventilated area, away from sources of heat, sparks, or open flames. It must be kept in tightly sealed containers to prevent moisture ingress. Store separately from oxidizing agents and strong acids. Proper labeling is essential, and access should be limited to trained personnel using appropriate personal protective equipment. |
