Normally, it takes the Bureau of Industry and Security (BIS) four to six weeks (from date of submission) to review and process an export license application. If the license requires a more in-depth review by additional agencies (DOE, DOD, DOS), the process could be as long as 90 days, but those cases are rare. Providing a detailed End-User Statement (EUS) and a completed and signed BIS711 will certainly expedite the license application filing process. The EUS and BIS711 are available from LND Sales Dept.
The warranty period is six months.
Return Authorization numbers are currently not required. Please contact the LND Sales and Customer Service Department before returning any items.
LND has produced selected MSDS's for customers who require them. Please contact Steve Davies if you require an MSDS for an LND product.
Before the Department of Defense (DoD) can purchase or procure services, products or materials for use by the U.S. Military, these items must be inspected and tested to government specifications. After extensive testing and inspections, those items that meet the specifications are considered to be "qualified" for DoD procurement.
DoD maintains QPLs (Qualified Product Lists) for various programs and these lists show the products' government designation (also referred to as a "JAN" number) and the authorized vendor or supplier.
LND currently has six (6) electron tubes that have been qualified for DoD procurement.
Generally, detectors containing gas at pressures above 2260 Torr (absolute pressure at 20 degrees C) or containing flammable or toxic gas must be shipped as Dangerous Goods/Hazardous Material. The majority of our detectors may ship under section 173.310 of 49CFR or as excepted quantities under the IATA regulations. Please see the specific examples below, and do not hesitate to contact us if you have questions.
The following special permit is used for the vast majority of Helium-3 tubes, Ionization Chambers and tubes containing Hydrogen, Methane or Propane:DOT SP 14183
The following special permit is used for three specific high-pressure Ionization chamber designs:DOT SP 10529
For international shipments, include the corresponding Competent Authority Approval with the DOT Special permit:
Exceptions for small detectors containing non-flammable, non-toxic gas at pressures above 2260 Torr at 20 degrees C:
Detectors with volumes of 30cc or less can ship as IATA excepted quantities when transported by air. Detectors containing 100 milligrams or less of gas can ship as not-restricted under IATA special provision A69.
Exceptions for Boron trifluoride neutron detectors:
Detectors containing 1 gram or less of Boron trifluoride, and filled to not more than 105 kPa absolute at 20 degrees C, are not subject to the hazardous materials regulations. All modes of transportation are allowed, including passenger aircraft. Please refer to IATA special provision A190 and U.S. DOT special provision 238.
Detectors containing more than 1 gram of Boron trifluoride, but not more than 12.8 grams, and filled to not more than 105 kPa absolute at 20 degrees C, must be shipped under IATA special provision A190 and/or DOT special provision 238. These special provisions allow for all modes of transportation, both domestic and international, except passenger aircraft.
In order to comply with special provision A190 and special provision 238, detectors must be shipped in a sealed plastic bag or plastic liner along with an absorbent capable of absorbing all of the gas contained in the detectors. Activated alumina is an effective absorbent for Boron trifluoride, and should be used in a ratio of 6:1, absorbent to BF3. For example, a detector containing 1 gram of BF3 must be packaged with a minimum of 6 grams of activated alumina.
Radiation detection equipment that uses Boron trifluoride neutron detectors as components installed inside of polyethylene neutron moderating enclosures will be in compliance with the special provisions, provided that activated alumina is included in the plastic enclosure and the plastic enclosure is hermetically sealed with a gasket.
Detectors containing more than 12.8 grams of Boron trifluoride and/or at pressures exceeding 105 kPa absolute at 20 degrees C, must ship under LND's DOT Special Permit 12087 and A2 competent authority approval. See links below.DOT SP 12087
When using DOT SP 12087 for international shipments, you must include LND's A2 Competent Authority Approval:
LND has two Permits of Equivalent Level of Safety from Transport Canada.
Most of LND's detectors have been classified as ECCN EAR99 or 1A999 by the Bureau of Industry and Security (BIS). Certain models of our 3He tubes are covered by the ECCN 1C232. Our BF3 detectors and B10 lined detectors have been assigned ECCN 1A999 by BIS.
