Content: 1.These Directions are stipulated by the Bureau of Standards, Metrology and Inspection (BSMI) for 
implementing the inspection of petroleum products.

2.Scope of Inspection: Petroleum Products that are imported or domestically-manufactured to be 
placed on the market.

3.Inspection schemes: monitoring inspection or management-system-based monitoring inspection.

4.Product name, type, inspection standards and inspection items for petroleum products are 
specified in Table 1.

5.Relevant requirements of monitoring inspection (including management-system-based monitoring 
inspection):
(1)Application:
a.Monitoring inspection: The obligatory inspection applicant shall apply to the BSMI or its branch 
(hereinafter referred to as the Inspection Authority) for inspection by submitting an inspection 
application form before the product is imported or transported out of the production premises.
b.Management-system-based monitoring inspection:
(a)An applicant shall register in the monitoring system and submit the application form, together 
with quality management system certificates issued by the BSMI or by certification bodies 
recognized by the BSMI, and a list of basic inspection equipment, to the Inspection Authority.
(b)The required basic inspection equipment is specified in Table 2.
(2)Inspection procedures for Monitoring Inspection:
a.The inspection is carried out by batch examination. Where the obligatory inspection applicant 
applies for inspection for products of the same origin, the same production premise or brand, and 
the same type, which have passed batch examination for three consecutive batches, the rate of each 
batch afterwards sampled for inspection shall be reduced to 20%. Where non-compliance is found in 
the randomly sampled products, batch examination will be resumed.
b.For petroleum products subject to batch inspection or randomly sampled for inspection, an 
inspection certificate will be issued based on a test analysis report (original) issued by 
BSMI-designated testing laboratory upon confirmation of compliance of the products with relevant 
requirements. Products may still be sampled for inspection if there are safety concerns. Where there 
is no non-compliance record of the products in the submitted application for batch inspection or 
where the products are sampled for inspection, the content of test analysis reports may include test 
results of major inspection items. For other situations, the content of test analysis reports shall 
contain test results of all inspection items.
c.The inspection shall be performed on major items if there is no non-compliance record of the 
products in the submitted application for batch inspection or if the products are sampled for 
inspection. The BSMI shall develop plans to monitor compliance with the other inspection items. If 
there are non-compliance records in batch inspection, all inspection items shall be conducted.
(3)Management-system-based monitoring inspection:
a.Domestically-manufactured cement to be sold in Taiwan: A production premise shall perform 
inspection of its cement and issue, by countersigning, the inspection certificate if compliance is 
demonstrated after the inspection.
b.For imported cement: the obligatory inspection applicant shall submit a copy of the registration 
certificate of the production premise under management-system-based monitoring inspection and 
the inspection records (original) produced by the production premise to the BSMI for approval 
before issuing the inspection certificate.

6.Inspection agency:
(1)Liquefied petroleum gases (LPG): Keelung, Taichung and Kaohsiung Branches of the BSMI. 
Samples taken by the BSMI headquarters, Hsinchu Branch or Hualien Branch of the BSMI are 
inspected by Keelung Branch; while the samples taken by Tainan Branch of the BSMI are inspected 
by Kaohsiung Branch.
(2)Petroleum products other than LPG:
a.Major inspection items: to be performed by BSMI Branches. Samples taken by the BSMI 
headquarters will be inspected by Keelung Branch.
b.Items other than major inspection items: to be performed by BSMI Branches or by inspection 
bodies commissioned by the BSMI.

7.Sampling:
(1)Method: The Branch of the BSMI receiving the inspection application will assign a staff member 
to take samples from the ship, the bonded tanks (sealed) or the storage tanks of the production 
premise.
(2)Inspection standards: CNS 1217 “Method of practice for manual sampling of petroleum and 
petroleum products” and CNS 12952 “Method for Sampling Liquefied Petroleum (LP) Gases.”
(3)Quantity: The applicant keeps two samples, while the BSMI Branch keeps one sample (the 
applicant may sign an undertaking not to keep the samples and waive the right to retest the 
products).
a.LPG: 300 ml×4 at minimum (each sampling may be split into several sampling bottles, if it is 
needed).
b.Fuel oil: 2,000 ml × 2+1,000 ml × 1.
c.Aviation turbine fuels: 2,000 ml × 2+1,000 ml × 1.
d.Aviation gasolines and unleaded gasoline for automobile: 4,000 ml × 2+1,000 ml × 1.
e.Kerosene: 2,000 ml × 2+1,000 ml × 1.
f.Diesel fuel oils and automotive diesel fuel: 5,000 ml × 2+1,000 ml × 1.
(4)Sampling equipment is to be provided by the applicant.

8.Delivery of samples: As carrying petroleum products by public transportation is not allowed, 
samples may be delivered by the staff member of the BSMI Branch receiving the application to the 
inspection agency via transportation means provided by the applicant. 

9.Period of inspection: 
(1)LPG: two working days upon receipt of samples, and five working days if further review is 
needed.
(2)Fuel oil, aviation turbine fuels, aviation gasolines, unleaded gasoline for automobile, kerosene, 
diesel fuel oils and automotive diesel fuel: three working days upon receipt of samples, and six 
working days if further review is needed.

10. Monitoring plan:
(1)Products and inspection items to be monitored: for petroleum products certified by having their 
major items inspected, compliance with the rest of the inspection items will be monitored; for 
petroleum products certified by providing test reports issued by BSMI-designated testing 
laboratories or produced by registered production premises under management-system-based 
monitoring inspection procedure, compliance with all inspection items shall be monitored. 
(2)Inspection agency: Clause 6 shall apply.
(3)Period of inspection: ten working days upon receipt of the samples and the inspection period 
mentioned in Clause 9 shall not apply.
(4)Actions to be taken if non-compliance is found in monitoring results:
a.Monitoring inspection: The inspection of petroleum products of the same place of origin, the same 
production premise or brand, the same model (the same type) is changed to batch inspection, 
covering all inspection items. Monitoring inspection shall be resumed under the circumstance that 
compliance with requirements is demonstrated for three consecutive batches.
b.Management-system-based monitoring inspection: The inspection of petroleum products of the 
same place of origin, the same production premise or brand, the same model (the same type) is 
changed to batch inspection for one to six months.
