Civil Reference No. 7 of 2004
North Mara Gold Mine Limited, a Tanzanian mining company, imported two Caterpillar dump trucks (CAT 785C) in June 2013. The trucks were packed and shipped in an unassembled state for ease of inland transportation. The appellant declared them under HS Code 8704.10.10 (a zero percent duty rate applicable to 'unassembled' goods), but the Tanzania Revenue Authority (TRA) classified them under HS Code 8704.10.90 ('other'), attracting a 10% ad valorem duty, on the basis that goods imported unassembled merely for convenience of transport are to be classified as complete articles. The appellant's objection was rejected by TRA, and its subsequent appeals to the Tax Revenue Appeals Board and the Tax Revenue Appeals Tribunal were both dismissed, the Tribunal affirming that the classification under HS Code 8704.10.90 was correct and that the mode of transportation had no bearing on the HS Code classification. The appellant then appealed to the Court of Appeal of Tanzania under section 25 of the Tax Revenue Appeals Act.
(1) Whether the dump trucks, imported and declared by the appellant as 'unassembled', were properly chargeable with duty under HS Code 8704.10.10 (zero rate) or HS Code 8704.10.90 (10% rate); and (2) Whether the dump trucks qualified for exemption from import duty as 'machinery' under item 30(B) of the Fifth Schedule to the East African Community Customs Management Act, 2004.
The appellant, through Dr. Kibuta Ongwamuhana, argued that: there was no legal requirement that unassembled trucks be assembled at a licensed assembly plant for the zero-rate classification to apply; goods must be classified according to their form at the time of importation, and the trucks were genuinely unassembled, not merely 'disassembled' for convenience; Rule 1 of the General Interpretation Rules of the HS Code required classification according to the specific tariff heading rather than by conjecture, and the Tribunal disregarded this; the mode of transportation of the trucks was irrelevant to their tariff classification; and the trucks qualified as 'machinery' exempt from import duty under item 30(B) of the Fifth Schedule to the EAC Customs Management Act. He relied on two Indian Supreme Court decisions (Union of India v Tarachand Gupta and Bros; Modi Xerox Ltd. v Collector of Customs) to support strict adherence to Rule 1 of the HS Code's interpretation rules. The respondent, through Mr. Beleko, argued that: the trucks were not genuinely 'unassembled' but were merely arranged/disassembled for ease of transport, and thus fell under the 'other' classification (HS Code 8704.10.90); the classification of imported goods must indeed be based on their state at importation, but the evidence showed the trucks were not in the unassembled state contemplated by the zero-rate code; the Indian authorities cited were factually distinguishable; and the exemption under item 30(B) did not apply because there was no evidence the appellant had declared the trucks as exempt at importation, and in any event the trucks did not qualify as machinery for oil, gas or geothermal exploration as required by that provision.
The Court of Appeal dismissed the appeal with costs. On the exemption issue, the Court agreed with the Board and Tribunal that item 30(B) of the Fifth Schedule to the EAC Customs Management Act was intended to exempt machinery, spares and inputs for direct use in oil, gas and geothermal exploration; since the dump trucks were not for such use, the exemption did not apply. On the classification issue, the Court held that although the Tribunal erred in relying on an unproven and uncited requirement that an assembly plant be licensed at the mine site, this error did not resolve the substantive classification question. Applying the General Rules for Interpretation (GRI) of the HS Code, the Court found that GRI 1 alone (classification by the terms of the heading) could not determine the character of the imported goods because a customs officer must first be satisfied the goods were vehicles ready for transport of goods; therefore GRI 2 had to be invoked. Under GRI 2(a), unassembled or disassembled articles are classified as complete articles if they possess the essential character of the finished product once assembled. Since it was undisputed that the trucks were packed unassembled purely for convenience of inland transport and were, once assembled, to be used to transport goods (rock), they possessed the essential character of complete dump trucks. Consequently, they were correctly classified under HS Code 8704.10.90, attracting a 10% duty rate, and not under the zero-rated 'unassembled' code. The Court also found no merit in the argument that the mode of transportation was wrongly considered relevant, noting the Tribunal had merely restated a fact introduced by the appellant itself without treating it as determinative of classification.
The judgment articulates and applies foundational canons of tax statute construction under the Tanzanian Constitution (Article 138) — that no tax is collectable without legal authority, that tax statutes must be strictly construed with ambiguities resolved against the tax authority, and that literal interpretation prevails unless it produces manifest absurdity. More specifically for customs law, the decision clarifies the hierarchical application of the General Rules for Interpretation (GRI) of the Harmonized Commodity Description and Coding System as domesticated under the Customs (Management and Tariff) Act: GRI 1 (classification by heading terms) must be attempted first, but where it cannot resolve classification—such as where goods are imported unassembled—GRI 2(a) applies, deeming unassembled or disassembled articles to be classified as their complete counterparts if they possess the essential character of the finished product. The case thus provides Tanzanian authority on how 'unassembled' goods imported for convenience of transport are to be tariff-classified, emphasizing substance (essential character) over form (state of packaging) in customs classification disputes, and confirms strict eligibility criteria for machinery exemptions under the EAC Customs Management Act's Fifth Schedule.
