General. This section provides for the identification of merchandise or articles for drawback purposes by the use of accounting methods. This section applies to identification of merchandise or articles in inventory or storage, as well as identification of merchandise used in manufacture or production (see § 191.2(h) of this subpart). This section is not applicable to situations in which the drawback law authorizes substitution (substitution is allowed in specified situations under 19 U.S.C. 1313(b), 1313(j)(2), 1313(k), and 1313(p); this section does apply to situations in these subsections in which substitution is not allowed, as well as to the subsections of the drawback law under which no substitution is allowed). When substitution is authorized, merchandise or articles may be substituted without reference to this section, under the criteria and conditions specifically authorized in the statutory and regulatory provisions providing for the substitution.

Conditions and criteria for identification by accounting method. Manufacturers, producers, claimants, or other appropriate persons may identify for drawback purposes lots of merchandise or articles under this section, subject to each of the following conditions and criteria:

The lots of merchandise or articles to be so identified must be fungible (see § 191.2(o) of this part);

The person using the identification method must be able to establish that inventory records (for example, material control records), prepared and used in the ordinary course of business, account for the lots of merchandise or articles to be identified as being received into and withdrawn from the same inventory. Even if merchandise or articles are received or withdrawn at different geographical locations, if such inventory records treat receipts or withdrawals as being from the same inventory, those inventory records may be used to identify the merchandise or articles under this section, subject to the conditions of this section. If any such inventory records (that is, inventory records prepared and used in the ordinary course of business) treat receipts and withdrawals as being from different inventories, those inventory records must be used and receipts into or withdrawals from the different inventories may not be accounted for together. If units of merchandise or articles can be specifically identified (for example, by serial number), the merchandise or articles must be specifically identified and may not be identified by accounting method, unless it is established that inventory records, prepared and used in the ordinary course of business, treat the merchandise or articles to be identified as being received into and withdrawn from the same inventory (subject to the above conditions);

Unless otherwise provided in this section or specifically approved by Customs (by a binding ruling under part 177 of this chapter), all receipts (or inputs) into and all withdrawals from the inventory must be recorded in the accounting record;

The records which support any identification method under this section are subject to verification by Customs (see § 191.61 of this part). If Customs requests such verification, the person using the identification method must be able to demonstrate how, under generally accepted accounting procedures, the records which support the identification method used account for all merchandise or articles in, and all receipts into and withdrawals from, the inventory, and the drawback per unit for each receipt and withdrawal; and

Any accounting method which is used by a person for drawback purposes under this section must be used without variation with other methods for a period of at least one year, unless approval is given by Customs for a shorter period.

Approved accounting methods. The following accounting methods are approved for use in the identification of merchandise or articles for drawback purposes under this section.

First-in, first-out (FIFO)—(i) General. The FIFO method is the method by which fungible merchandise or articles are identified by recordkeeping on the basis of the first merchandise or articles received into the inventory. Under this method, withdrawals are from the oldest (first-in) merchandise or articles in the inventory at the time of withdrawal.

Example. If the beginning inventory is zero, 100 units with $1 drawback attributable per unit are received in inventory on the 2nd of the month, 50 units with no drawback attributable per unit are received into inventory on the 5th of the month, 75 units are withdrawn for domestic (non-export) shipment on the 10th of the month, 75 units with $2 drawback attributable per unit are received in inventory on the 15th of the month, 100 units are withdrawn for export on the 20th of the month, and no other receipts or withdrawals occurred in the month, the drawback attributable to the 100 units withdrawn for export on the 20th is a total of $75 (25 units from the receipt on the 2nd with $1 drawback attributable per unit, 50 units from the receipt on the 5th with no drawback attributable per unit, and 25 units from the receipt on the 15th with $2 drawback attributable per unit). The basis of the foregoing and the effects on the inventory of the receipts and withdrawals, and balance in the inventory thereafter are as follows: On the 2nd of the month the receipt of 100 units ($1 drawback/unit) results in a balance of that amount; the receipt of 50 units ($0 drawback/unit) on the 5th results in a balance of 150 units (100 with $1 drawback/unit and 50 with $0 drawback/unit); the withdrawal on the 10th of 75 units ($1 drawback/unit) results in a balance of 75 units (25 with $1 drawback/unit and 50 with $0 drawback/unit); the receipt of 75 units ($2 drawback/unit) on the 15th results in a balance of 150 units (25 with $1 drawback/unit, 50 with $0 drawback/unit, and 75 with $2 drawback/unit); the withdrawal on the 20th of 100 units (25 with $1 drawback/unit, 50 with $0 drawback/unit, and 25 with $2 drawback unit) results in a balance of 50 units (all 50 with $2 drawback/unit).

Last-in, first out (LIFO)—(i) General. The LIFO method is the method by which fungible merchandise or articles are identified by recordkeeping on the basis of the last merchandise or articles received into the inventory. Under this method, withdrawals are from the newest (last-in) merchandise or articles in the inventory at the time of withdrawal.

Example. In the example in paragraph (c)(1)(ii) of this section, the drawback attributable to the 100 units withdrawn for export on the 20th is a total of $175 (75 units from the receipt on the 15th with $2 drawback attributable per unit and 25 units from the receipt on the 2nd with $1 drawback attributable per unit). The basis of the foregoing and the effects on the inventory of the receipts and withdrawals, and balance in the inventory thereafter are as follows: On the 2nd of the month the receipt of 100 units ($1 drawback/unit) results in a balance of that amount; the receipt of 50 units ($0 drawback/unit) on the 5th results in a balance of 150 units (100 with $1 drawback/unit and 50 with $0 drawback/unit); the withdrawal on the 10th of 75 units (50 with $0 drawback/unit and 25 with $1 drawback/unit) results in a balance of 75 units (all with $1 drawback/unit); the receipt of 75 units ($2 drawback/unit) on the 15th results in a balance of 150 units (75 with $1 drawback/unit and 75 with $2 drawback/unit); the withdrawal on the 20th of 100 units (75 with $2 drawback/unit and 25 with $1 drawback/unit) results in a balance of 50 units (all 50 with $1 drawback/unit).

Low-to-high—(i) General. The low-to-high method is the method by which fungible merchandise or articles are identified by recordkeeping on the basis of the lowest drawback amount per unit of the merchandise or articles in inventory. Merchandise or articles with no drawback attributable to them (for example, domestic merchandise or duty-free merchandise) must be accounted for and are treated as having the lowest drawback attributable to them. Under this method, withdrawals are from the merchandise or articles with the least amount of drawback attributable to them, then those with the next higher amount, and so forth. If the same amount of drawback is attributable to more than one lot of merchandise or articles, withdrawals are from the oldest (first-in) merchandise or articles among those lots with the same amount of drawback attributable. Drawback requirements are applicable to withdrawn merchandise or articles as identified (for example, if the merchandise or articles identified were attributable to an import more than 5 years (more than 3 years for unused merchandise drawback) before the claimed export, no drawback could be granted).

Ordinary—(A) Method. Under the ordinary low-to-high method, all receipts into and all withdrawals from the inventory are recorded in the accounting record and accounted for so that each withdrawal, whether for export or domestic shipment, is identified by recordkeeping on the basis of the lowest drawback amount per unit of the merchandise or articles available in the inventory.

Example. In this example, the beginning inventory is zero, and receipts into and withdrawals from the inventory are as follows:

The drawback attributable to the January 15 withdrawal for export is zero (the available receipt with the lowest drawback amount per unit is the January 2 receipt), the drawback attributable to the January 28 withdrawal for domestic shipment (no drawback) is zero (the remainder of the January 2 receipt), the drawback attributable to the February 5 withdrawal for export is $100.50 (the January 5 and January 20 receipts), the drawback attributable to the February 15 withdrawal for export is $47.50 (the February 10 receipt), the drawback attributable to the February 23 withdrawal for domestic shipment (no drawback) is zero (the February 20 receipt), the drawback attributable to the February 28 withdrawal for export is $102.50 (the January 25 and January 31 receipts), the drawback attributable to the March 15 withdrawal for export is $42.50 (the March 10 receipt), the drawback attributable to the March 21 withdrawal for domestic shipment (no drawback) is $52.50 (the February 25 receipt), and the drawback attributable to the March 31 withdrawal for export is $98.00 (the March 25 and March 5 receipts). Remaining in inventory is the March 20 receipt of 50 units ($1.08 drawback/unit). Total drawback attributable to withdrawals for export in this example would be $391.00.

Low-to-high method with established average inventory turn-over period—(A) Method. Under the low-to-high method with established average inventory turn-over period, all receipts into and all withdrawals for export are recorded in the accounting record and accounted for so that each withdrawal is identified by recordkeeping on the basis of the lowest drawback amount per available unit of the merchandise or articles received into the inventory in the established average inventory turn-over period preceding the withdrawal.

Accounting for withdrawals (for domestic shipments and for export). Under this method, domestic withdrawals (withdrawals for domestic shipment) are not accounted for and do not affect the available units of merchandise or articles. All withdrawals for export must be accounted for whether or not drawback is available or claimed on the withdrawals. Once a withdrawal for export is made and accounted for under this method, the merchandise or articles withdrawn are no longer available for identification.

Establishment of inventory turn-over period. For purposes of this section, average inventory turn-over period is based on the rate of withdrawal from inventory and represents the time in which all of the merchandise or articles in the inventory at a given time must have been withdrawn. To establish an average of this time, at least 1 year, or three (3) turn-over periods (if inventory turns over less than 3 times per year), must be averaged. The inventory turn-over period must be that for the merchandise or articles to be identified, except that if the person using the method has more than one kind of merchandise or articles with different inventory turn-over periods, the longest average turn-over period established under this section may be used (instead of using a different inventory turn-over period for each kind of merchandise or article).

Example. In the example in paragraph (c)(3)(ii)(B) of this section (but, as required for this method, without accounting for domestic withdrawals, and with an established average inventory turn-over period of 30 days), the drawback attributable to the January 15 withdrawal for export is zero (the available receipt in the preceding 30 days with the lowest amount of drawback is the January 2 receipt, of which 50 units will remain after the withdrawal), the drawback attributable to the February 5 withdrawal for export is $101.50 (the January 20 and January 25 receipts), the drawback attributable to the February 15 withdrawal for export is $47.50 (the February 10 receipt), the drawback attributable to the February 28 withdrawal for export is $51.50 (the February 20 and January 31 receipts), the drawback attributable to the March 15 withdrawal for export is $42.50 (the March 10 receipt), and the drawback attributable to the March 31 withdrawal for export is $98.00 (the March 25 and March 5 receipts). No drawback may be claimed on the basis of the January 5 receipt or the February 25 receipt because in the case of each, there were insufficient withdrawals for export within the established average inventory turn-over period; the 50 units remaining from the January 2 receipt after the January 15 withdrawal are not identified for a withdrawal for export because there is no other withdrawal for export (other than the January 15 withdrawal) within the established average inventory turn-over period; the March 20 receipt (50 units at $1.08) is not yet attributed to withdrawals for export. Total drawback attributable to withdrawals for export in this example would be $341.00.

Low-to-high blanket method—(A) Method. Under the low-to-high blanket method, all receipts into and all withdrawals for export are recorded in the accounting record and accounted for so that each withdrawal is identified by recordkeeping on the basis of the lowest drawback amount per available unit of the merchandise or articles received into inventory in the period preceding the withdrawal equal to the statutory period for export under the kind of drawback involved (e.g., 180 days under 19 U.S.C. 1313(p), 3 years under 19 U.S.C. 1313(c) and 1313(j), and 5 years otherwise under 19 U.S.C. 1313(i)). Drawback requirements are applicable to withdrawn merchandise or articles as identified (for example, if the merchandise or articles identified were attributable to an import more than 5 years (more than 3 years for 19 U.S.C. 1313(j); more than 180 days after the date of import or after the close of the manufacturing period for 19 U.S.C. 1313(p)) before the claimed export, no drawback could be granted).

Accounting for withdrawals (for domestic shipments and for export). Under this method, domestic withdrawals (withdrawals for domestic shipment) are not accounted for and do not affect the available units of merchandise or articles. All withdrawals for export must be accounted for whether or not drawback is available or claimed on the withdrawals. Once a withdrawal for export is made and accounted for under this method, the merchandise or articles withdrawn are no longer available for identification.

Example. In the example in paragraph (c)(3)(ii)(B) of this section (but, as required for this method, without accounting for domestic withdrawals), the drawback attributable to the January 15 withdrawal for export is zero (the available receipt in the inventory with the lowest amount of drawback is the January 2 receipt, of which 50 units will remain after the withdrawal), the drawback attributable to the February 5 withdrawal for export is $50.00 (the remainder of the January 2 receipt and the January 5 receipt), the drawback attributable to the February 15 withdrawal for export is $47.50 (the February 10 receipt), the drawback attributable to the February 28 withdrawal for export is $50.50 (the February 20 and January 20 receipts), the drawback attributable to the March 15 withdrawal for export is $42.50 (the March 10 receipt), and the drawback attributable to the March 31 withdrawal for export is $96.00 (the March 25 and January 25 receipts). Receipts not attributed to withdrawals for export are the January 31 (50 units at $1.03), February 25 (50 units at $1.05), March 5 (50 units at $1.06), and March 20 (50 units at $1.08) receipts. Total drawback attributable to withdrawals for export in this example would be $286.50.

Average—(i) General. The average method is the method by which fungible merchandise or articles are identified on the basis of the calculation by recordkeeping of the amount of drawback that may be attributed to each unit of merchandise or articles in the inventory. In this method, the ratio of:

The total units of a particular receipt of the fungible merchandise in the inventory at the time of a withdrawal to;

The total units of all receipts of the fungible merchandise (including each receipt into inventory) at the time of the withdrawal;

Is applied to the withdrawal, so that the withdrawal consists of a proportionate quantity of units from each particular receipt and each receipt is correspondingly decreased. Withdrawals and corresponding decreases to receipts are rounded to the nearest whole number.

Example. In the example in paragraph (c)(1)(ii) of this section, the drawback attributable to the 100 units withdrawn for export on the 20th is a total of $133 (50 units from the receipt on the 15th with $2 drawback attributable per unit, 33 units from the receipt on the 2nd with $1 drawback attributable per unit, and 17 units from the receipt on the 5th with $0 drawback attributable per unit). The basis of the foregoing and the effects on the inventory of the receipts and withdrawals, and balance in the inventory thereafter are as follows: On the 2nd of the month the receipt of 100 units ($1 drawback/unit) results in a balance of that amount; the receipt of 50 units ($0 drawback/unit) on the 5th results in a balance of 150 units (100 with $1 drawback/unit and 50 with $0 drawback/unit); the withdrawal on the 10th of 75 units (50 with $1 drawback/unit (applying the ratio of 100 units from the receipt on the 2nd to the total of 150 units at the time of withdrawal) and 25 with $0 drawback/unit (applying the ratio of 50 units from the receipt on the 5th to the total of 150 units at the time of withdrawal)) results in a balance of 75 units (with 50 with $1 drawback/unit and 25 with $0 drawback/unit, on the basis of the same ratios); the receipt of 75 units ($2 drawback/unit) on the 15th results in a balance of 150 units (50 with $1 drawback/unit, 25 with $0 drawback/unit, and 75 with $2 drawback/unit); the withdrawal on the 20th of 100 units (50 with $2 drawback/unit (applying the ratio of the 75 units from the receipt on the 15th to the total of 150 units at the time of withdrawal), 33 with $1 drawback/unit (applying the ratio of the 50 units remaining from the receipt on the 2nd to the total of 150 units at the time of withdrawal, and 17 with $0 drawback/unit (applying the ratio of the 25 units remaining from the receipt on the 5th to the total of 150 units at the time of withdrawal)) results in a balance of 50 units (25 with $2 drawback/unit, 17 with $1 drawback/unit, and 8 with $0 drawback/unit, on the basis of the same ratios).

Inventory turn-over for limited purposes. A properly established average inventory turn-over period, as provided for in paragraph (c)(3)(iii)(C) of this section, may be used to determine:

The fact and date(s) of use in manufacture or production of the imported designated merchandise and other (substituted) merchandise (see 19 U.S.C. 1313(b)); or

The fact and date(s) of manufacture or production of the finished articles (see 19 U.S.C. 1313(a) and (b)).

Approval of other accounting methods. (1) Persons proposing to use an accounting method for identification of merchandise or articles for drawback purposes which has not been previously approved for such use (see paragraph (c) of this section), or which includes modifications from the methods listed in paragraph (c) of this section, may seek approval by Customs of the proposed accounting method under the provisions for obtaining an administrative ruling (see part 177 of this chapter). The conditions applied and the criteria used by Customs in approving such an alternative accounting method, or a modification of one of the approved accounting methods, will be the criteria in paragraph (b) of this section, as well as those in paragraph (d)(2) of this section.

In order for a proposed accounting method to be approved by Customs for purposes of this section, it shall meet the following criteria:

For purposes of calculations of drawback, the proposed accounting method must be either revenue neutral or favorable to the Government; and

The proposed accounting method should be:

Generally consistent with commercial accounting procedures, as applicable for purposes of drawback;

Consistent with inventory or material control records used in the ordinary course of business by the person proposing the method; and

Easily administered by both Customs and the person proposing the method.
