Sourcing Thermal Carbon Black from China

Zero duty on thermal carbon black

Read from the UK Trade Tariff on 4 October 2026, heading 2803 covers carbon blacks and other forms of carbon not elsewhere specified or included. Thermal carbon black falls within the single commodity line 2803 00 00 00. The table shows purchasing forms sharing that line, rather than separate tariff subdivisions. Goods from China carry 0% duty, with no anti-dumping or countervailing measure and no suspension shown.

The tariff attaches import waste control and also lists an export waste control. For a shipment from China to England that is waste subject to notification controls, shipment can start only after consent from the Environment Agency and the other competent authorities involved. If the supplier offers recovered material or describes the goods as waste, confirm the applicable requirements with your customs broker before ordering.

Confirm the composition and presentation using our commodity code guide, particularly for dispersions or masterbatches. See the wider carbon black guide for other carbon black families.

Specify thermal grade and compound performance

Ask the producer to identify the thermal production route, feedstock, grade and manufacturing site. State whether you want powder or pellets, and agree limits for iodine adsorption, oil absorption, ash, moisture, sieve residue and pour density, with named test methods. Request a batch certificate of analysis and retain an approved sample.

Trial the proposed thermal grade in your own compound. Record dispersion, mixing behaviour and the finished properties your application needs. Agree that the producer must obtain your approval before changing the grade, production site or material source.

Importers are responsible for chemical classification. Confirm whether UK REACH registration applies through our UK REACH guide. Request the safety data sheet and plan dust handling before delivery; confirm applicable workplace exposure requirements with HSE.

Worked duty example

Illustrative example, not a quote: Illustrative order: 20 tonnes of pelletised thermal carbon black in bulk bags under 2803 00 00 00, invoiced at £22,000 free on board, with £2,000 of freight and insurance to the UK. The customs value is £24,000. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £24,000, so it is £4,800. With no duty, the only import tax is the VAT, which a VAT-registered importer can usually reclaim. The import duty and VAT guide explains each step.

Inspection checklist

Identity: match the thermal grade, producer and batch references on the bags, certificate and order.

Batch quality: sample across the lot and compare iodine adsorption, oil absorption, ash, moisture and sieve residue with the agreed specification.

Physical form: check powder or pellet form, pellet breakdown and fines where relevant, then compare dispersion with the approved sample.

Packing: check liners, closures, bag weights, pallet condition and signs of water ingress or carbon leakage. Agree the sampling scope through our inspection guide.

What goes wrong

A substitute carbon black can look similar while changing mixing and finished compound performance. A matching description on the invoice is insufficient purchasing evidence. Keep the approved sample, batch analysis and compound trial results together, and investigate unexplained changes before accepting the lot.

Grit, excessive ash, damp material and damaged packaging can cause defects or handling problems. Pellets that break during transit create fines; pellets that resist dispersion can leave visible particles. Record arrival condition and hold suspect bags pending sampling and review.
