Premium Leather Bag Grade Selection Explained: Six Questions Before You Sign a Hide Clause

Question One: What Does Selection Mean on a Hide?

Selection is the name a tannery gives to how much usable surface survived the hazards of the animal's life and the hazards of the tanning process. It is assigned at the tannery, not at the cutting table, and it is expressed as a name rather than as a test result.

That distinction matters because two houses can use the same selection word for different things. One may grade on surface defects only; another may also fold in substance regularity and handle. Before discussing price, make every selection word resolve to a written description attached to your order.

• Selection grades describe usable surface, usually assessed defect by defect.
• Grades are assigned by eye and experience, then recorded per hide or per bundle.
• Naming conventions differ between houses; the written description governs, not the word.
• Grading covers tanning damage as well as natural marks from the animal's life.
• The same word can cover two different realities unless it is written down.

Some makers dismiss grading as commercial language rather than technical language. They are half right: the word is commercial, but the yield it predicts is as technical as anything in your specification, and it is the number that decides your cost per unit.

Question Two: How Much of a Lot Reaches Top Selection?

Fewer hides than most plans assume. On a typical premium delivery, top selection is usually in the range of 15-25% of the hides received; second selection accounts for roughly 40-55%, and the balance goes lower. Plan your prices against that distribution rather than against the best sample you were shown.

Top selection

Typically 15-25% of a delivery, prime panel area largely intact

Second selection

Typically 40-55%, usable with careful pattern layout

Lower selections

The balance, suited to small panels, linings and facings

Substance tolerance

+/-0.1 mm within a declared band, measured with a dial gauge

Bundle practice

Hides are usually sold by bundle, mixed selections within stated limits

Resorting right

Agree in writing what happens when a bundle misses the stated mix

The fifth line is where disagreements start. A bundle is a practical way to sell, but if the stated mix is not written into the order, the tops of three bundles will quietly drift and the cutting rejects will drift with them.

Question Three: What Counts as a Defect, Panel by Panel?

A defect is only a defect in relation to the pattern piece it would spoil. A healed scar sitting in the middle of a gusset does nothing to a body panel, and the same scar in the centre of a front panel ruins it. Define defects against panel area, not against the hide overall.

Write the allowance as numbers rather than adjectives. State the maximum number of healed scars per panel area, the largest measurement any single one may reach, and whether holes, brand marks or thin grain are acceptable anywhere in the prime area. Adjectives invite arguments at intake, numbers settle them.

Applying the third card literally across a whole hide will push you up a selection grade for no functional gain. Grade tightly where the visible panels come from and sensibly everywhere else, and the arithmetic improves without the surface looking different.

Question Four: How Tight Should Substance Tolerance Be?

Substance is the thickness of the leather, measured in millimetres, and for a premium body it is usually declared as a band rather than a single figure. A typical declaration is 1.2-1.4 mm with a permitted variation of +/-0.1 mm across hides in one delivery.

Tightening further is possible and rarely worth it. Below +/-0.1 mm the hides have to be sorted again by touch, which adds handling cost and forces further divides in an already small pool of grade A hides. The visible result of a looser tolerance usually shows in structure rather than in comfort.

• Declare substance as a band, typically 1.2-1.4 mm for a structured body.
• Permit +/-0.1 mm variation across a delivery rather than demanding uniformity.
• Measure with a dial gauge at agreed points, not at the thickest or thinnest.
• Separate the requirement for bodies from the requirement for facings and linings.
• Record the measured figures per bundle so fabric panel sorting can plan around them.

The fourth bullet saves money more often than any other line in the specification. Facings, straps and interior panels do not need the substance you specified for the front body, yet many orders apply one figure across every component.

Question Five: Who Grades, and Under What Light?

Grading is a visual judgement, so it is entirely dependent on the conditions it is made under. Hides should be assessed flat on a neutral surface in consistent light, commonly judged under a D65 source at around 1,000 lux, by graders working to one written standard.

The light is not pedantry. Signs of damage that vanish under warm showroom lighting are obvious under daylight-equivalent conditions, and a decision reached at nine in the morning is not the decision reached at the end of a shift. Ask where grading happens and what it is judged under, then put both in the order.

The fourth row deserves attention. A sealed reference set is the least costly lever in this entire article: it converts every later argument from a matter of opinion into a matter of comparison.

Question Six: What Should the Purchase Clause Say?

The clause is where grading becomes enforceable. It should name the selections permitted, the share each selection may take within a bundle, the defect allowance by area, the substance band with tolerance, the light and reference used, and what happens when a delivery misses any of them.

Most clauses stop at the first two items, which is why most grading disputes are unresolvable. Without a remedy written down, a buyer who finds 9% instead of 22% top selection has a grievance rather than a claim, and grievances are settled by whoever has more patience.

1. Name the permitted selections in writing, with the tannery's own descriptions attached.
2. State the share each selection may take within a bundle and overall.
3. Set the defect allowance by panel area rather than across the hide.
4. Declare the substance band and the permitted variation across a delivery.
5. Fix the light, the surface and the sealed reference used for grading.
6. Write the remedy: replacement, credit, or acceptance against an agreed adjustment.

Grading Language Compared

The vocabulary differs enough between houses to be worth translating. The terms below cover what most premium trade conversations mean, but the written definition always supersedes the word used in an email.

The fourth row explains a counter-intuitive pricing effect. Correcting a surface lets lower-choice hides become visually consistent, which is why a corrected-grained runner and a full-grain choice sit closer in price than their yield suggests.

What Grade Costs at the Cutting Table

Grade matters because it converts directly into cutting rejects. Moving from a lower selection to top selection on the same pattern typically raises hide cost while reducing sorting rejects, and the two numbers move in opposite directions at different rates.

• A tighter selection usually adds to hide cost and cuts rejects at the table.
• The saving appears as labour and time rather than as material returned.
• Mixed-selection bundles can be the pragmatic answer for multi-component bodies.
• Extra sorting and pairing adds roughly USD 4.80 per unit on medium structured bodies.
• Component planning lets one body carry two selections without visible difference.
• Yield figures quoted without a selection assumption describe nothing you can buy.

The last line is the one to carry into any negotiation. A yield figure offered without stating which selection it assumes is not a quotation; it is a wish, and it will be revised on the day the first bundle arrives.

Writing Grade Into Your Own Specification

Bring the six answers together as one sheet that travels with the order and travels with the hides. One page, six entries, each with a number, is enough to make a grade argument resolvable months later by someone who was not in the original conversation.

Our development programme works to MOQ 500 pcs per style and colourway, with sampling at 6-10 working days and 12-15 days where a body is complex, and bulk at 35-50 days on FOB Xiamen terms, inspected to AQL 2.5 under ISO 2859-1. It runs across 7 production lines with about 200,000 pcs per month of capacity and export experience since 2014, delivered through our validated partner factory Quanzhou Yingming Bags, an SGS-validated site. Hides are graded on the grey table before intake, against the sealed reference rather than from memory.
