Carbon black n330 price manufacturers

Buyers must prioritize the Iodine Adsorption Number (82 ± 7 g/kg) and DBP Absorption Number (102 ± 7 10⁻⁵m³/kg), as these define the reinforcement properties in rubber. Additionally, ensure the Heating Loss is below 2.5% and Ash Content is less than 0.5% to prevent impurities from affecting the final product's structural integrity.

N330 is a High Abrasion Furnace (HAF) grade, making it ideal for tire treads, high-quality rubber conveyor belts, and industrial rubber products that require a balance of high tensile strength and tear resistance. It is also widely used as a pigment and UV stabilizer in plastics and coatings.

Suppliers should provide ISO 9001:2015 for quality management and ISO 14001 for environmental standards. For international trade, ensure the product complies with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) for the EU market and ASTM D1765 for standard classification of carbon blacks used in rubber products.

The price of N330 is heavily influenced by raw material costs (coal tar and ethylene tar) and environmental regulation compliance costs. Buyers should monitor the crude oil market and consider long-term contracts to hedge against price volatility, while also factoring in the Total Cost of Ownership (TCO) including specialized logistics for hazardous or messy powder handling.

The main risks include moisture contamination during sea transit and packaging failure. Carbon black is a fine powder; if the valve bags or jumbo bags are punctured, it causes severe environmental contamination and product loss. Always insist on palletized packaging with shrink-wrap and verify the supplier's Trade Assurance status on Made-in-China.com to secure the transaction.

Request a Pre-Shipment Inspection (PSI) by third parties like SGS or Intertek to verify the particle size distribution and tint strength. For pricing, negotiate based on volume-based tiers; typically, orders exceeding 20 tons (one full container load) can yield a 5-10% discount. Ask for a fixed-price window of 30-60 days to protect against sudden raw material spikes.

Carbon black is generally classified as non-hazardous for transport (unless it is self-heating), but it is extremely 'dirty' cargo. Ensure the shipping line accepts carbon black and that the container is clean and dry. For shipping to specific regions, ensure the HS Code (280300) is correctly declared to avoid customs delays and check for any anti-dumping duties applicable in your country.

Utilize the secured payment systems provided by Made-in-China.com to ensure funds are only released upon proof of shipment. Conduct a factory audit (virtual or physical) to confirm the supplier has the production capacity to meet your lead times, which typically range from 15 to 25 days for bulk chemical orders.
