Ctc manufacturers

When procuring CTC machinery, focus on the roller diameter and length, typically ranging from 8 to 13 inches, as this dictates throughput capacity. Ensure the rollers are made of hardened stainless steel or high-grade carbon steel to resist abrasion. Look for segment-type rollers which allow for easier maintenance and individual segment replacement. Additionally, verify the motor power (HP) and the presence of variable frequency drives (VFD) to control the speed of the rollers for different leaf conditions.

Quality is determined by leaf appearance, infusion color, and liquor strength. Demand samples categorized by grade: BOP (Broken Orange Pekoe), BP (Broken Pekoe), and OF (Orange Fannings). Ensure the tea meets ISO 3720 standards for black tea. Request a Certificate of Analysis (CoA) that details moisture content (should be <5%), total ash, and water extract levels to ensure the product hasn't been adulterated.

Suppliers must adhere to HACCP (Hazard Analysis and Critical Control Points) and ISO 22000 food safety management systems. For specific markets, ensure the product is FDA registered (USA) or compliant with EFSA MRLs (Maximum Residue Limits) for pesticides (EU). If sourcing organic CTC, a USDA Organic or EU Organic certification is non-negotiable.

CTC tea is primarily used for tea bags and instant tea premixes due to its quick infusion properties and strong flavor profile. It is also the standard base for Chai (spiced tea) in South Asian markets. For industrial buyers, it serves as a raw material for RTD (Ready-to-Drink) bottled beverages where high extract yield is required for cost-efficiency.

Specify the harvest season (Flush) in the contract and require vacuum-sealed aluminum foil lining within the bulk sacks or plywood chests to prevent moisture ingress. Use Third-Party Inspection (TPI) services like SGS to conduct a loading supervision to ensure the tea is fresh and the containers are dry and odor-free.

Leverage volume-based pricing; for CTC tea, prices drop significantly at the 5-ton and 10-ton thresholds. Request FOB (Free On Board) pricing to maintain control over your shipping costs. Always ask for a pre-shipment sample (PSS) that is drawn from the actual production lot, and state that the final payment is contingent on the bulk matching the PSS.

Utilize Secured Trading Services provided by the platform to ensure funds are only released upon proof of shipment. For high-value machinery, use a Letter of Credit (L/C) or a staged payment plan: 30% deposit, 60% against BL (Bill of Lading) copy, and 10% after quality arrival inspection.

Machinery should be shipped in seaworthy wooden crates (ISPM 15 certified) with anti-rust coating or VCI (Vapor Corrosion Inhibitor) packaging. Ensure the supplier provides a foundation drawing and installation manual in English. For shipping to landlocked regions or specific ports, confirm the Incoterms 2020 clearly to define who handles the inland transit and customs clearance.
