CSARS v Mining Pressure Systems (Pty) Ltd (565/2023)
The Supreme Court of Appeal (SCA) has ruled in The Commissioner for SARS v Mining Pressure Systems (Pty) Ltd that certain seamless steel pipes imported from China were correctly classified by SARS as “line pipe of a kind used for oil or gas pipelines”, which attracts 10% customs duty.
Background to the dispute
Mining Pressure Systems (Pty) Ltd imported seamless carbon steel pipes from China and supplies them to the mining industry. Before SARS’ tariff determination, the company cleared the pipes duty free under tariff heading 7304.39.35, which applies to certain seamless pipes of iron or non-alloy steel.
For several years, the company cleared these pipes under a tariff heading that allowed them to enter duty free. In January 2019, SARS issued a tariff determination reclassifying the pipes under TH 7304.19.90, described as “line pipe of a kind used for oil or gas pipelines”, resulting in 10% duty.
Mining Pressure Systems challenged this determination in the High Court, arguing that the pipes were not the type typically used in oil or gas pipelines. The High Court agreed and set aside SARS’ classification. SARS then appealed the decision to the Supreme Court of Appeal.
What Was Disputed
Both parties agreed on the physical nature of the goods. The pipes were seamless carbon steel pipes manufactured according to the API 5L standard, a widely used international specification for pipeline steel.
The dispute was not about what the pipes were made of, but rather whether they belonged to the category of pipes used in oil or gas pipelines.
SARS argued that because the pipes complied with the API 5L standard — which is commonly used in the oil and gas industry — they should be classified as pipeline pipes.
The company, however, argued that the pipes were lower-strength pipes (grade X42) and smaller than those typically used in major oil and gas transmission pipelines. According to its expert evidence, these pipes were more suited to industrial applications such as mining water systems.
The judgment of the SCA
The Supreme Court of Appeal overturned the High Court decision and ruled in favour of SARS. It emphasised that tariff classification must be based on the objective characteristics of the goods at the time they are imported, rather than how the importer intends to use them.
Because the pipes complied with the API 5L specification — an international standard used for pipes designed to transport oil and gas — the court held that they were “of a kind used for oil or gas pipelines.”
The court also rejected the argument that only larger or stronger pipes qualify for this category. It explained that pipeline design depends on various engineering factors such as pressure and system requirements, meaning different pipe grades and sizes may still be used in pipelines.
As a result, the court concluded that the pipes were correctly classified under the tariff heading applicable to line pipe used for oil or gas pipelines, which attracts a 10% customs duty. The appeal by SARS was therefore upheld with costs, and the earlier High Court order was set aside.
Why the case matters
This judgment reinforces an important principle in customs law: classification depends on the nature and characteristics of the goods, not the importer’s intended use. For businesses importing specialised equipment or materials, this case highlights the importance of accurate tariff classification and the potential financial impact if SARS determines that goods fall within a duty-paying category.
