The most widely used classification for quaternary ammonium-modified organoclay in international trade is 3824.99 — “Chemical preparations, not elsewhere classified.” A secondary classification in some markets is 2508.10 (Bentonite), applied when customs authorities treat the product primarily as a clay mineral. A third code, 2853.90 (Other inorganic compounds), appears in certain destination tariff schedules. The material’s CAS No. is 68153-34-4.

Declaring under the wrong code can result in examination delays or duty miscalculation. Confirm the applicable code with your import customs broker before filing, using the supplier’s product description document and CAS number as reference inputs.

Standard MOQ for direct export is one full 20-foot container load — approximately 17–18 metric tons in 25 kg multi-wall bags, or 18–20 metric tons in 1,000 kg FIBC jumbo bags. LCL shipments are available from 500 kg to 5 metric tons with freight surcharge. Small trial orders of 50–500 kg are possible at higher unit pricing. Free samples of 200 g to 2 kg are standard before any commercial purchase commitment.

Three-stage process: Stage 1 — Documentation review: ISO 9001 certification, batch-specific COA with measured values (not specification ranges only), SDS for destination country, TDS per grade. Stage 2 — Sample qualification: Test 0.5–2 kg in your specific formulation system — target solvent, base oil, and process equipment. Record TI, viscosity, and application performance as baseline data. Stage 3 — Trial order: 1–5 metric tons enables production-scale verification and batch consistency assessment before full-container commitment.

→ Begin your evaluation — samples shipped within 48 hours for qualified inquiries.

Required documentation: batch-specific COA with measured values for moisture content, loss on ignition, and particle fineness (referencing production batch number and test date); SDS in GHS format for the destination country; TDS with performance parameters, dosage ranges, and incorporation procedure; Commercial Invoice and Packing List with accurate HS code. A COA listing only pass/fail against specification ranges without batch-specific measured values provides insufficient traceability for quality-controlled procurement.

Four factors beyond unit price: Grade performance equivalency — a lower-priced grade may require a 30–50% higher treat rate, erasing the apparent cost advantage; compare cost-per-unit-of-performance. Incoterm basis — convert all quotes to landed cost (freight, insurance, import duty, customs clearance) before comparing. Batch consistency — request COA data from three to five consecutive batches to assess production variability before awarding volume. Supply reliability — verify stock availability and quoted lead times against actual regional delivery records.
